Computer Science/Điện Toán Học

Sample / Học Computer Science/Điện Toán Học


CS [Computer Science] thì không nên thiếu C# (C Sharp).
Computer = máy điện toán
Computer = điện toán học

Học Computer Science, nhưng lĩnh vực này quá rộng, nó có đôi chút kiến thức võ vẽ về viết chương trình bằng ngôn ngữ Java cho vui, không chuyên sâu.

Bây giờ cháu nó đam mê lĩnh vực điện toán, và tò mò cái gì cũng muốn biết. Nhưng tui biết có nhiều đứa học CS (Computer Sciencera) ít có việc làm, hay lương không cao; ngược lại có nhiều đứa Úc không học uni mà lại làm developers lương rất cao. Bằng cấp của những đứa này nếu có cũng ít khi liên quan.

Sau rồi lại thấy Dr Tran là bác sĩ, anh TrungThuc5 làm consultant, tui không biết cái nghề này có nhất thiết phải học uni không? Thực lòng mong nghe các vị chỉ giáo.

Tui ngu độn, không dạy con cháu được, thực lấy làm xấu hổ.

Nếu phải học Computer Science ở Đại Học thì nên học ngôn ngữ nào, phải giành bao nhiêu giờ tối thiểu để luyện viết? Tui đọc sơ qua quyển Computer Science Dummies thì có các ngôn ngữ .NET, JAVA, C++,...

Ngoài việc rành ngôn ngữ, thì phải học thêm về cái gì để có tương lai?

Tui có tìm hiểu về Infomation Security, nhưng mà trình độ không tới, không hiểu được.

Nếu lạc đề quá xin tạ lỗi với Dr Tran và các vị vậy.

- Có lẽ không sao đâu! Chủ đề kiến thức học hành, kiến thức con người VN, Dr Trần chắc cũng khoái như tôi.

- Cháu của bác nếu có ý thích học Computer Science (CS) thì cứ việc xin nhập học ở các trường đại học. Học ngành nào cũng vậy, trường càng có tiếng thì càng có sự cạnh tranh. Mà càng có sự cạnh tranh thì người sinh viên mới có dịp trau dồi nhiều, trau dồi nhiều thì kiến thức chuyên môn nhiều - Hoc Computer Science cũng vây.

Ngày nay, các trường ĐH ở Mỹ curriculum về Computer Science hoặc được dạy bởi C++ hoặc Java. Nhưng ngôn ngữ Computer Science dù là C++, Java và cho dù đi lùi lại học C cũng không quan trọng. Vì ngôn ngữ chỉ là sự chuyển đạt mà thôi. Các chương trình về Computer Science người ta chỉ chú trọng dạy về nhiều thứ concepts, methodology, rồi đến data structures, algorithm Analysis (*1). Một thí dụ như, hồi ở ĐH tôi chuyên ngành Mechanical Engineering. Khi ra trường thì lại đi làm cho Intel, chuyên nghiên cứu về IC packaging, rồi nghề nghiệp lại cần đến sự hiểu biết về programming, nên phải tự trau dồi và sau đó trở thành chuyên môn về Computer Science luôn. Rồi khi đi dạy part time ở JC gần hãng vào ban đêm, trường cần thầy có hiểu biết sâu về programming methode nên thuê tôi. Thế là tôi càng có dịp trau dồi chuyên sâu hơn nữa. Thí dụ này để cho ta biết rằng người thầy ở Mỹ không phải họ đều biết hết mọi thứ. Nhưng vì có sự học thâm sâu, nếu cần họ có thể nắm bắt một thứ gì đó, mới mẻ, một cách nhanh chóng hơn là dân học dốt. Bao nhiêu thầy khác ở Mỹ cũng vậy, có thầy có PhD về Physics mà lại dạy về Microprocessor, thậm chí có thầy có MD, PhD về Microbiology rồi lại bỏ nghề bác sĩ y khoa đi dạy về Computer Science. Brian Kernighan và Dennis Ritchie (K&R) cũng tuơng tự, hai ông tổ của C programming language, một người xuất thân từ Electrical Engineering, người từ applied math.

Do đó cần nhấn mạnh nhiều lần rằng - một người lãnh đạo quốc gia cần phải là người từng là một người học giỏi từ tiểu học, trung học, lên đến đại học, và ngành chuyên nghiệp sau đại học / post graduate. Mục đích để họ nắm bắt một vấn đề của hiện tại và tuơng lại của đất nước một cách nhanh chóng hơn người bình thường.

Nếu có đam mê về Computer Science thì cứ tìm trường có tiếng mà học và học hết mình. Lên graduate thì nên tìm cách sang Mỹ học thì sẽ mở mang được nhiều hơn. Một thí dụ như Brian Kernighan, sau khi tốt nghiệp ở University of Toronto, Canada (trường này cũng là trường hạng nhất của Canada), nhưng ông đã xin vào Princeton để học PhD về Electrical Engineering.

Tóm lại, học Computer Science, ngôn ngữ C, C++, Java... chỉ là cái dụng cụ, tools mà thôi. Sở dĩ bây giờ đa số các trường Đại Học chọn C++, hoặc Java là để sinh viên lên năm thứ ba, thứ tư, không xa lạ khi học các môn học liên quan đến object oriented/môn chính.

Ghi chú:
(*1) Không dịch được mấy chữ chuyên môn này ra tiếng Việt, nếu cố dịch chỉ làm tối nghĩa thêm mà thôi.

PS.

Chỉ học lơ mơ mới không có việc làm mà thôi. Đã học Computer Science thì không nên thiếu C# (C Sharp).


C# (C Sharp) được lead bởi Anders Hejlsberg viết dot net FRAMEWORK là nền tảng của hệ điều hành Windows hiện giờ. Anders Hejlsberg là tổ của Delphi bên Borland. Từ ngày Bill bứng Anders Hejlsberg về M$ thì Borland tàn luôn.

http://en.m.wikipedia.org/wiki/Anders_Hejlsberg

JavaWorld of 1997 writes how Hejlsberg went to Microsoft: Microsoft offered Anders Hejlsberg a signing bonus of US$500,000 and stock options. Microsoft doubled the bonus to US$1,000,000 after Borland made a counter-offer. Hejlsberg left Borland in October 1996.

Anders Hejlsberg (/hɑːlsbɛrɡ/, born December 1960)[2] is a prominent Danish software engineer who co-designed several popular and commercially successful programming languages and development tools. He was the original author of Turbo Pascal and the chief architect of Delphi. He currently works for Microsoft as the lead architect of C#[1] and core developer on TypeScript.

http://en.m.wikipedia.org/wiki/Anders_Hejlsberg
Early lifeEdit

Hejlsberg was born in Copenhagen, Denmark, and studied engineering at the Technical University of Denmark but did not graduate.[3] While at the university in 1980, he began writing programs for the Nascom microcomputer, including a Pascal compiler which was initially marketed as the Blue Label Software Pascal for the Nascom-2. However, he soon rewrote it for CP/M and DOS, marketing it first as Compas Pascal and later as PolyPascal. Later the product was licensed to Borland, and integrated into an IDE to become the Turbo Pascal system. Turbo Pascal competed with PolyPascal. The compiler itself was largely inspired by the "Tiny Pascal" compiler in Niklaus Wirth's "Algorithms + Data Structures = Programs", one of the most influential computer science books of the time. Anders and his partners ran a computer store in Copenhagen and marketed accounting systems. Their company, PolyData, was the distributor for Microsoft products in Denmark which put them at odds with Borland. Philippe Kahn and Anders first met in 1986. For all those years, Niels Jensen, one of Borland's founders and its majority shareholder, had successfully handled the relationship between Borland and PolyData.[citation needed]

At BorlandEdit

In Borland's hands, Turbo Pascal became one of the most commercially successful Pascal compilers.[4] Hejlsberg remained with PolyData until the company came under financial stress, at which time, in 1989 he moved to California and became Chief Engineer at Borland. There he remained until 1996. During this time he developed Turbo Pascal further, and eventually became the chief architect for the team which produced the replacement for Turbo Pascal, Delphi.

At MicrosoftEdit

Hejlsberg at the Professional Developers Conference 2008.
In 1996, Hejlsberg left Borland and joined Microsoft. One of his first achievements was the J++ programming language and the Windows Foundation Classes; he also became a Microsoft Distinguished Engineer and Technical Fellow. Since 2000, he has been the lead architect of the team developing the language C#. In 2012 Hejlsberg announced his new project TypeScript—a superset of JavaScript.

AwardsEdit

He received the 2001 Dr. Dobb's Excellence in Programming Award for his work on Turbo Pascal, Delphi, C# and the Microsoft .NET Framework.

Together with Shon Katzenberger, Scott Wiltamuth, Todd Proebsting, Erik Meijer, Peter Hallam and Peter Sollich, Anders was awarded a Technical Recognition Award for Outstanding Technical Achievement for their work on the C# language in 2007. A video about this is available at Microsoft Channel 9.[5]

Trích dẫn từ bài viết của tangle2
Cha mẹ muốn con cái thành đạt thì cha mẹ phải tu nhân tích đức, đời này qua đời khác rồi mới từ từ khá lên. Chứ không thể cha mẹ bình dân mà con cái nhảy vọt ngay một bước thành giới trí thức tinh hoa hàng đầu được.
Đúng vậy, chỉ học "cách làm sang" mà thôi. Đó là nhà nghèo trúng số học cách đứng ngồi của nhà giàu.
Nếu học đi theo các nghiên cứu thì phải mất 10 năm.

Cha mẹ bình dân thì không thể dạy cho con cái nhân cách, lối hành xử khôn khéo, cách giải quyết vấn đề, biết nhẫn nhịn khi cần, cách dùng từ ngữ xã giao, từ ngữ ngoại giao, cách thức giao tế, cách thuyết phục người khác, cách lãnh đạo, cách chấp nhận và tùng phục bề trên, quyền lực, v.v...

Do đó, thật là sai lầm khi nói rằng "tôi làm neo nuôi con ăn học!"

Sai bét, cha mẹ làm neo thì cho dù có tiền cũng không thể nuôi con, dạy dỗ, để chúng học lên tuyệt đỉnh.

Cha mẹ đi làm trong sở thì có thể hơn, cho dù chỉ làm chức nhỏ. Vì trong đó học được nhiều điều về dạy con cháu.

Tôi có người quen qua đây hồi bốn tuổi, học ra đại học. Chê lương thấp, ra làm neo. Trước đây anh ta nói toàn tiếng Anh, đúng giọng. Mới đây gặp lại anh ta nói tiếng Việt còn rành hơn tôi, nhưn giọng nhà quê, chữ dùng thô kệch vì trong tiệm neo nói toàn tiếng Việt. Anh ta mới có con, với một cô làm chung tiệm nail. Thôi tiêu đời đứa con! Cha mẹ biết gì ngoài tiệm neo mà dạy dỗ.

Muốn gia nhập giới "trí thức tinh hoa hàng đầu" thì cần nhiều loại "soft skills", "people's skills", và EQ (emotional quotient) phải rất cao.

EQ muốn cao thì phải gia nhập nhiều hội đoàn, du lịch nhiều, tham gia nhiều trại hè, vào nhiều nhóm thể thao, âm nhạc, kịch nghệ, v.v... Và như vậy cần tiền, cần dẫn dắt.

Đứa trẻ đi trại hè về muốn kể cho cha mẹ nghe, hỏi ý kiến nhiều điều, trong khi cha mẹ làm nhà hàng, tiệm neo, thì biết gì mà nói, chưa kể không đủ ngoại ngữ mà nói. Đứa trẻ do đó không theo kịp bạn bè, bị chê bỏ vì "s/he doesn't know anything", từ từ sẽ bị đào thải ra khỏi nhóm, có khi xấu hổ bị trầm cảm, nhát, tránh đám đông luôn.

Tôi có đứa cháu họ nói "My Dad doesn't know anything", và đây là 1 pharmacist học tại Mỹ, chỉ là đứa nhỏ học giỏi quá, "bung" ra xã hội nhiều, còn người cha chỉ đi làm về rồi coi phim Tàu, Hàn quốc. May là cha mẹ cũng biết họ kém, cuối tuần chở lên cho tôi dạy thêm.

3 đứa cháu vô Duke, MIT, Yale, cũng là 1 tay tôi dạy, chứ cha mẹ chúng không đủ trình độ xã hội.

Từ lớp 6, tôi đã dạy chúng học cái này cái nọ, chơi piano thì cha mẹ phải mua cho cây Steinway, tiếng đàn hay chúng mới ham học, chứ mua đàn điện tử $1500 thì đánh hư tay, tiếng không hay, chúng mau chán.

Chơi violon thì 2/4, 3/4 không nói, lên tới 4/4 (full size) thì phải mua cây ít gì $10.000 mới tạm gọi là ok, để chúng nhận thấm các khúc nhạc hay, chứ các loại như Suzuki thì cho Joshua Bell đàn cũng chỉ là để dỗ ngủ.

Rồi còn phải đi đủ loại trại hè trong nước, ngoài nước, trên biển.

Khi phỏng vấn, phải có nhiều thành tích ngoại khóa, nhiều điều để nói mới được nhận vào, chứ chỉ biết học thì trừ khi là đại thiên tài, không đời nào vô được Yale, Duke.

Các cô cậu từ VN nếu theo tiêu chuẩn học sinh trong xứ Mỹ thì không ai được vào Ivies, tôi dám chắc chắn 100%. Đem họ so với đám cháu họ tôi thì thua xa tới mức không thể so sánh vì quá khác ĐẲNG CẤP.

Vô rồi thì phải tốn rất nhiều tiền để chúng theo kịp bạn bè, được vô nhóm học chung, có điểm cao, mới vô trường y, luật sau này.

Nhiều cô cậu từ Somalia, Algerie, Việt Nam lon ton vô các nơi này, như báo Mỹ "khen" gần đây, thì cũng khó thành công do không có tiền, có people's skills, soft skills, để làm group projects, học nhóm cho có điểm cao.

Cậu George Huynh này nếu ra được Yale, GPA 3.0, là may:
http://www.bostonglobe.com/metro/201...1jJ/story.html

Do thông minh, họ cũng sẽ tốt nghiệp, nhưng hầu như chắc chắn sẽ không đứng đầu lớp để học lên Tiến sĩ, Bác sĩ, Luật sư trong các trường hàng đầu sau này.

Vì lẽ do ít tiền, không có tài gì khác ngoài học, họ sẽ không có nhiều bạn thuộc loại giàu sụ, có nhiều tài ngoại khóa, sẽ không được cho coi các test banks, không vào nhóm học chung, không có GS chống lưng. Học solo thì được B là may.

What is it like to be poor at an Ivy League school?

High-achieving, low-income students, often the first in their families to attend college, struggle to feel they belong on elite campuses.

The son of an MBTA bus driver from Jamaica Plain, Harvard sophomore Ted White helps lead the First Generation Student Union, pushing for a better understanding of challenges financially disadvantaged students face.

By Brooke Lea Foster APRIL 09, 2015

WHEN ANA BARROS first stepped into Harvard Yard as a freshman, she felt so out of place she might as well have had the words “low income” written on her forehead. A girl from Newark doesn’t belong in a place like Harvard, she thought, as she marveled at how green the elms were, how quaint the cobblestone streets. Back home, where her family lives in a modest house bought from Habitat for Humanity, there wasn’t always money for groceries, and the world seemed gray, sirens blaring at all hours. Her parents, who immigrated to the New York area from Colombia before she was born, spoke Spanish at home. It was at school that Barros learned English. A petite 5-foot-2 with high cheekbones and a head of model-worthy hair, Barros found out in an e-mail that she’d been accepted to Harvard — a full scholarship would give her the means to attend. “I knew at that moment that I’d never suffer in the way that my parents did,” she says.

She opted for a single her freshman year, because she felt self-conscious about sharing a room with someone from a more privileged background. “All you see are class markers everywhere, from the way you dress to the way you talk,” says Barros, now a junior sociology major, as she sits in a grand, high-ceilinged space off the dining room in her Harvard College dorm. During her freshman and sophomore years, Barros hesitated to speak in class because she often mispronounced words — she knew what they meant from her own reading, but she hadn’t said many aloud before, and if she had, there had been no one to correct her. Friends paired off quickly. “You’d get weeded out of friendships based on what you could afford. If someone said let’s go to the Square for dinner and see a movie, you’d move on,” she says. Barros quickly became close with two other low-income students with whom she seemed to have more in common. She couldn’t relate to her peers who talked about buying $200 shirts or planning exotic spring break vacations. “They weren’t always conscious of how these conversations can make other people feel,” she says. In a recent sociology class, Barros’s instructor asked students to state their social class to spark discussion. “Middle,” said one student. “Upper class,” said another. Although she’d become accustomed to sharing her story with faculty, Barros passed. It made her uncomfortable. “Admitting you’re poor to your peers is sometimes too painful,” she says. “Who wants to be that one student in class speaking for everyone?”

For generations, attending an Ivy League college has been practically a birthright for children of the nation’s most elite families. But in 2004, in the hopes of diversifying its student body and giving low-income, high-achieving students a chance at an Ivy League education, Harvard announced a game-changing financial aid campaign: If a student could get in, the school would pick up the tab. (Princeton was the first Ivy to offer poor families the option, in 1998; Yale followed Harvard in 2005.) Families with incomes of less than $40,000 would no longer be expected to contribute to the cost of their student’s education. (In recent years, income eligibility has increased to $65,000, with significant grants awarded to families that make up to $150,000.) Having since been adopted, in one form or another, by all the Ivies, this “zero family contribution” approach opened the gilded doors of top colleges for many of the country’s most disadvantaged students. The number of students awarded a Pell Grant — financial aid of as much as $5,700 given to those with a family income of up to 250 percent of the poverty line, or about $60,000 for a family of four — is considered the best indicator of how many are low-income. At Harvard, where tuition, room, and board is estimated at $58,600, the Pell is a very small part of a student’s financial aid package. Last year, 19.3 percent of eligible Harvard students were awarded a Pell, an 80 percent increase since the admissions policy began 11 years ago. At Brown University, 15 percent of students get a Pell, and at Yale, 14 percent do.

But receiving a full scholarship to an Ivy League school, while a transformative experience for the nation’s poorest students, is only the first hurdle. Once on campus, students report feelings of loneliness, alienation, and plummeting self-confidence. Having grant money for tuition and fees and holding down jobs, too, as virtually all of them do, doesn’t translate to having the pocket money to keep up with free-spending peers. And some disadvantaged students feel they don’t have a right to complain to peers or administrators about anything at all; they don’t want to be perceived as ungrateful.

“IT’S TOTAL CULTURE SHOCK,” says Ted White, a Harvard sophomore. White grew up working class in Jamaica Plain and graduated as valedictorian (he was one of the only white kids in his senior class) from New Mission High School in Hyde Park; his father is an MBTA bus driver. From the start, the Harvard campus didn’t seem built for a kid from a background like his, he says. Classmates came in freshman year having started businesses or nonprofits (usually with their parents’ resources, he says) that could make even a top student wonder if he belonged. “The starting place for all of us isn’t really the same,” he says. White appreciates, for example, that Harvard gives low-income students free tickets to the freshman formal, but they have to pick up the tickets in a different line from everyone else. “It’s clear who is getting free/reduced tickets and who isn’t,” he says — a situation a Harvard spokesperson says the school is working to remedy. At times, White wondered if he’d made the right choice going to Harvard, even if he saw his matriculation, like many low-income students do, as his one shot at leaving his family’s financial struggles behind for good.

How did colleges become country clubs?

Stephen Lassonde, dean of student life at Harvard College, says first-generation students have it particularly tough because they’re wrestling with their identities, like all students, while simultaneously trying to transcend their socioeconomic backgrounds. “As much as we do to try to make them feel included, there are multiple ways that their roommates and peers can put them on the outside without even intending to,” he says.

Today, White, a sociology major, is vice president of Harvard’s First Generation Student Union, an advocacy and support network seeking to create positive institutional change for students whose parents never attended a four-year-college; Barros is the president. To hear them talk about it, the union has become a haven for Harvard’s poorest students, even if “first generation” doesn’t always mean poor. Low-income kids claimed the term when they realized how much easier it was to admit they were struggling partly because they were the first in their family to go to college, and not simply because they were poor, says Dan Lobo, who founded the union in 2013. Raised by Cape Verdean immigrant parents in Lynn — his dad cooks and his mom waits tables at hotels near Logan — Lobo spent a few tough years “trying to transition to Harvard.” After having dinner with two classmates in similar circumstances who also felt like an “invisible minority” on campus and struggled to make friends and keep up academically, Lobo decided to “come out” as a low-income, first-generation student and organized the First Generation Student Union. Urging others to talk more openly about how their background influenced their college experience, he sought to create a community that could advocate for change on campus. “At the time, no one was talking about first-gen issues at all,” says Lobo, who has since graduated (with highest honors) and works for a nonprofit that helps students of color get into elite private high schools. “It’s like Harvard was committed to admitting underprivileged kids, but then we got here and they didn’t know what to do with us.”

03/17/2015 - Providence, RI - Alejandro Claudio, cq, a freshman at Brown University, walks through campus on a sunny Tuesday afternoon. Claudio gained a full-ride scholarship to the Ivy League school, which is the only way that the son of poor immigrant parents could hope to attend. He is shocked regularly by the huge contrast between his world at school and the world he's used to at home. Claudio is majoring in economics. ÒIf I fail, IÕm going back to poverty, to working in a factory," said Claudio. "I need to get good grades and get a job that pays well enough to help feed my family,Ó added Claudio.

Freshman Alejandro Claudio navigates a different world at Brown. “If I fail, I’m going back to poverty, to working in a factory,” he says.

As at Harvard, low-income students at Yale and Brown have suggested administrators could do more to help them develop a sense of belonging. And they, too, have been organizing — Undergraduate First Generation Low Income Partnership sprang up in 2014 at Yale. At Brown, three students, including a Mexican-American kid from California named Manuel Contreras, started 1vyG, the Inter-Ivy, First Generation College Student Network, in January 2014. Contreras’s group organized a three-day conference this February that brought together students and administrators from other schools to share information and learn from one another. “Brown wasn’t made for students like us,” Contreras, a cognitive science major, often tells fellow members, “but we have to make it ours.”

All the groups are seeking greater visibility on campus: a more open dialogue about what it means to be a first-generation student at an Ivy League school, dedicated staff to serve as support, and a list of best practices so Ivies can use their abundant resources to ensure their most disadvantaged students are as equipped to succeed as other students. If the infrastructure at an Ivy League school assumes everyone comes from a certain socioeconomic background, as some first-generation students say, then change needs to come at an institutional level. Dining halls at some schools, for example, close for spring break, though some students can’t afford to leave campus. While tuition, room, and board may be covered. some universities tack on a “student fee” ranging from a few hundred to as much as a thousand dollars, an amount that can be devastating to those trying to figure out how to pay for books.

Rakesh Khurana, dean of Harvard College, grew up in Queens as the son of a teacher in the Bronx. “We have to do a better job at making sure every student feels comfortable here,” says Khurana, who recently organized a task force to that end. In December, Harvard appointed two first-generation liaisons — one in the office of financial aid, the other in the office of career services — to help ease the transition for students. In January, Jason Munster, a first-generation low-income graduate student in environmental sciences and engineering from Maine, was named Harvard College’s first “first-generation tutor.” If you’re poor and struggling, Munster is the person you can go to for help. With an undergraduate degree from Harvard, Munster is also the campus liaison for the Harvard First Generation Alumni Network, founded around the same time as the First Generation Student Union.

Still, students complain that Harvard worries too much about singling out first-generation students — the administration has been hesitant, for example, to offer them a specialized “bridge” program in the summer before their freshman year. Khurana waves the accusation off, saying that as a college Harvard is still figuring out how best to help. “I told the task force to imagine that we can create the best environment possible for these kids — no constraints,” he says. “What is the ideal? Can we create relationships earlier in their experience rather than later? Can we streamline certain forms of financial aid? It’s our goal to close this gap as quickly as possible.”

ON A SUNDAY in mid-January, 18-year-old Alejandro Claudio has just packed up his duffel bag at his family’s first-floor apartment in a run-down triple-decker on Waldo Street in Providence’s West End. A crumbling statue of the Virgin Mary sits on the porch; next door is the Cranston Street Rescue Mission, a soup kitchen. It’s just a 15-minute drive across the city back to school after winter break, but to Claudio, dressed most days in his Brown sweat shirt and Red Sox cap, Brown is worlds away from the neighborhood where he grew up. On campus, his “perfect world up on the hill,” he feels removed from the worries at home — how his mom, a day-care provider, and his dad, a welder, are going to make their rent or keep their lights on. A political science, philosophy, and economics major, Claudio is well aware, though, that he must succeed. “If I fail, I’m going back to poverty, to working in a factory. I need to get good grades and get a job that pays well enough to help feed my family.”

Claudio’s bright, windowed dorm room overlooks a grassy quad, and he can eat whenever he wants at the Ratty, the campus dining hall, because his meal plan is covered by his scholarship. During his first semester, friends looked at him like he had five heads when he said he’d never tasted falafel, kebabs, or curry. He had immigrated to the United States from the Dominican Republic when he was 8. “Growing up in a poor family, we ate the same thing every night: rice, beans, and chicken,” he says.

It was at Providence’s predominantly Latino Central High School that Claudio, who would go on to be class valedictorian, decided he didn’t want a job in the fish factories where many of his friends’ parents worked. He believed he might actually escape the West End when he met Dakotah Rice, his coach on the debate team and an undergrad low-income student at Brown. They’d get together at a Burger King across from Central to talk about Claudio’s future and his chances of going to Brown. “He understood my background, and we’d talk for hours about how I could get in. He was like, ‘If I can do it, you can too,’ ” says Claudio. Now that he’s on campus, Claudio sees just how big a social gap exists between him and other students. It was easy to mistake other African-American and Latino students as coming from a similar socioeconomic background — but after striking up a conversation, Claudio was shocked to learn many were as moneyed as his white peers. At the first ice cream social, one student mentioned his dad was a lawyer and his mom a doctor, then asked Claudio what his parents did. When he told them his dad was a welder, the conversation ended awkwardly. Later in the semester, Claudio confided in a well-off friend that his mom was asking him for money to help pay bills. “I’m sorry,” the friend said, which made Claudio feel worse. He’s since stopped sharing his background so openly.

After parachuting into a culture where many kids seem to have a direct line to prestigious internships through their well-off parents and feel entitled to argue with a professor over a grade, poor kids sense their disadvantage. Even if they’re in the same school as some of the nation’s smartest and best-connected young people, students’ socioeconomic backgrounds seem to dictate how they navigate campus. Research shows, for example, that upper-middle-class kids are better at asking for help at college than low-income ones, in part because they know the resources available to them. Disadvantaged students are accustomed to doing everything on their own because they rarely have parents educated enough to help them with things like homework or college applications, so they may be less likely to go to a writing center or ask a professor for extra help. Yolanda Rome, assistant dean for first-year and sophomore students at Brown, says many disadvantaged students have come to her in tears after getting a C on a paper. When she asks if they met with the instructor, the answer is typically no. “We’re working hard to change the campus culture,” she says, “so these students know that asking for help is not a weakness.”

Anthony Jack, a resident tutor at Harvard alongside Jason Munster, is a PhD candidate in sociology studying low-income students at elite colleges. He says low-income students show up at his office every other week looking to vent about frustrations with campus life — or to ask a question they don’t know whom else to ask, like “How do I get a recommendation for a fellowship?” In his research, Jack looks at the experiences of both the “privileged poor,” low-income students who attend an elite, private high school before college, and the “doubly disadvantaged,” or students who aren’t familiar with the expectations and norms of elite colleges. His findings suggest that low-income students’ success on campus may be tied to the social and cultural capital they possess. For example, do they arrive with the same sense of entitlement as their more affluent peers, do they understand the importance of developing one-on-one relationships with professors to earn future recommendations?

03/17/2015 - Providence, RI - Alejandro Claudio, cq, and his parents, Alejandro Claudio, cq, left, and Maribel Claudio, cq, right. Alejandro is now a freshman at Brown University and gained a full-ride scholarship to the Ivy League school, which is the only way that the son of poor immigrant parents could hope to attend. He is shocked regularly by the huge contrast between his world at school and the world he's used to at home. Claudio is majoring in economics.

Brown is just a 15-minute ride from the apartment in Providence’s West End where Alejandro Claudio’s parents, Alejandro and Maribel Claudio, live.

Jack says that the privileged poor adjust more easily to the campus culture than the doubly disadvantaged. The latter see professors as distant authority figures and feel guarded in approaching them, whereas the privileged poor, like upper-middle-class students, find it easier to cultivate the relationship. “You’re worth a professor’s time,” Jack will tell many of the students he mentors.

Does this reluctance to ask for help ultimately impact graduation rates? Perhaps not as much at an Ivy League school as elsewhere. Nationally, the graduation rate for low-income, first-generation students in bachelor’s programs is about 11 percent, but that number increases dramatically at Ivy League schools, where most of the financial burden is lifted from students. According to data collected by I’m First, an online community for first-generation college students funded by the Bill and Melinda Gates Foundation, at Harvard and Yale, 98 percent of students from minority groups underrepresented in college will graduate with a four-year degree within six years; at Brown, it’s 91 percent.

When recent Brown graduate Renata Martin first came to campus, she had no idea how poor her family was back in the Newark area, where her dad works as a pizza delivery driver. “Everyone who lived around us was getting their lights shut off — that was my normal,” she says. She used her campus health insurance to see a therapist for help with her identity struggles, but she couldn’t afford the $15 copays. Martin, who attended Brown on a $90,000 Jack Kent Cooke scholarship, says, “Brown assumes that all students can afford small extras like that, but we can’t.” During lean weeks, she’d stop in to see the campus chaplain to apply for funds to buy a book she couldn’t afford or a bus ticket home. “It’s really hard to ask for help,” she says. “But I had to get used to telling professors my story or I wouldn’t have gotten through Brown.”

Beth Breger is the executive director of Leadership Enterprise for a Diverse America, a nonprofit that helps prepare 100 high-achieving, low-income high school juniors per year for college and the application process. Its students spend seven weeks on Princeton University’s campus to study leadership and attend seminars on things like writing, standardized-test prep, and campus life. They’re introduced to the resources that exist on campus, like the career center, where they can learn how to network and prepare for job interviews. “Our students are very capable of doing the work academically, but we help them with social and cultural aspects of school: why it’s important to meet with their academic adviser and professors, how to access a health center. We don’t want them to feel like taking advantage of these resources is a weakness.” Bridge programs with similar goals exist for incoming freshmen at Princeton, Stanford, and Yale. Says Breger: “There’s a confidence issue with these kids. Many have never met a corporate lawyer or Wall Street trader. They don’t have a parent offering them a lens into the professional world. We try to broaden their perspective.”

WHEN JUNIOR Julia Dixon steps inside the small cafeteria at Trumbull College at Yale, the short-order cook flipping hamburgers lights up: “Hi, Ms. Julia, what can I get for you today?” A man stacking crates of clean glasses says to the Southern-born Dixon: “Ms. Julia, it’s too cold for a Georgia peach today, isn’t it?” Wearing black-rimmed glasses and lipstick the color of Japanese eggplant, Dixon may be a long way from her childhood as the second oldest of 11 growing up on food stamps in rural Georgia. But she sees the dining room workers as family. In fact, when her parents rented a car and drove up to visit, they were nervous around Dixon’s friends — but they asked to meet the cafeteria workers. “Can you watch out for my baby girl?” her father asked the short-order cooks. That her parents reached out to dining hall staff on their one visit to campus, rather than a professor or faculty member, gets at the heart of the split identity Dixon has grappled with since her freshman year.

She’s come to see herself as “Georgia Julia” and “Yale Julia,” and reconciling the two identities is complicated. Even her parents sense the change. On her second (and most recent) visit home in the three years she’s been at school, her father voiced concern at dinner one night that her education might cause her to drift away from them. “I don’t want you to be ashamed of us,” he said. At first, Dixon wouldn’t talk to her parents about what she was going through at school — a tough class she was taking, how much money she had in her bank account. She’s since realized that the only way to stay connected to them is to talk openly about her problems, even if most of what she’s experiencing is foreign to them.

Poor students may feel out of place at an Ivy League school, but over time, they may feel as if they don’t belong at home, either. “Often, they come to college thinking that they want to return home to their communities,” says Rome, the Brown official. “But an Ivy League education puts them in a different place — their language is different, their appearance is different, and they don’t fit in at home anymore, either.”

Ellie Dupler, a junior global affairs major at Yale with wavy, reddish-brown hair and silver hoop earrings she picked up in Turkey on a Yale-funded trip, lived in a trailer with her single mother in northern Michigan until she was in the sixth grade. In high school, she took a public bus two hours each way to a better public school than the one in her hometown. She’s on a tight budget when we meet at Blue State coffeehouse in New Haven. “I’m waiting for a check from financial aid, so I’ve been skipping some meals,” she says. Even so, Dupler says Yale has given her a false sense of financial security. “Frankly, the longer I’m here, the less that I feel I identify with having a low-income background.”

Along with working three jobs, she’s on the school’s ski team — her mom operated the chairlift at a resort near her hometown, and Dupler could ski for free. When she shared her background with some of her teammates, they were surprised. “I would have never have known you were low income,” one told her. Her best friend, who is from a wealthy suburb of New York City, helps her out when she needs it, though Dupler says she’s quick to repay her. Dupler thinks she’s been able to blend in more easily at Yale than some other low-income students because she’s white. “Typically, unless I disclose my background in some way, I’m assumed to be just like most of the other white students who grew up upper middle class in a perfect house in the suburbs,” she says. She likes seeing herself through other students’ eyes. Maybe it’s even convinced her that she can live a different kind of life.

Still, graduation looms, and she worries about making it without the security of a Yale scholarship. “I feel like here I’m moving up the socioeconomic ladder. But when I graduate, will I slip back down?” As a result, she says, she’s become obsessed with her career. “My friends joke that my aspirations change weekly.” She’s currently set on getting a graduate degree in law and public policy and eventually a career in international relations.

Julia Dixon says she tries not to see money as the most defining element of her identity anymore. Yale has shown her a life where dinner conversations don’t revolve around overdue bills. She’s using the time to think about her future — without worrying about the financial means she needs to get there. “Money is something I’ve learned to disassociate from. Maybe I see these four years as my chance to dream.”

BROWN GROUP BRINGS FIRST-GENS FROM MANY CAMPUSES TOGETHER

By Emeralde Jensen-Roberts

Esther Maddox from Princeton, Jasmine Fernandez from Harvard, and Kujegi Camara, also from Princeton, attended an open dialogue session at Brown’s 1vyG conference for first-generation students in February.

A new group at Brown brings first-gens from many campuses together to agitate for change.

On a frosty Saturday morning in February, more than 200 students, some wearing sleek business suits, file in to Brown University’s C.V. Starr auditorium. As they wait for the day’s program to start, they sit in small, chatty packs, picking at blueberry muffins and sipping coffee from paper cups. Some take selfies with friends, later tweeted and hashtagged “1vyG2015.”

Hailing from Brown and 15 other schools, some Ivies and some not, the students and more than 20 college administrators are here at the invitation of 1vyG, a first-generation student network launched last year at Brown. 1vyG’s founders, juniors Manuel Contreras, Jessica Brown, and Stanley Stewart, have been studying the obstacles that first-generation students like them face at Brown, and the three-day conference, believed to be the first of its kind, is a natural extension of that. Are students at other schools dealing with the same challenges, and how can they share information to help improve campus life for all?

The weekend’s workshops are geared to fostering discussion between first-generation students and administrators and to boosting students’ coping skills on campus and beyond. Sessions include Navigating Class and Culture on Campus, Building a Career as a First-Gen, and Coaching College-Bound Students to Succeed.

Contreras comes away from the event determined to repeat it. “At bare minimum, we’re going to be an annual rotating conference,” he says, with different schools playing host. Additional ambitions at Brown include setting up a textbook lending library and establishing a mentorship program to connect incoming students with current first-generation upperclassmen and alumni.

The ultimate goal remains constant: keep pushing schools to broaden their view and keep encouraging students to find strength through their shared experience. “I want first-gens to be connected, [to] feel happy and that they belong,” says Contreras. “You may be the first, but you’re not alone.”

Học y tại Mỹ, khó vô cùng

Quote:

Trích dẫn từ bài viết của Trungthuc5 Xem Bài

Mới đây tôi có đến nhà một ngừoi quen ăn tiệc, ông chủ nhà có khoe có đứa cháu gái ruột bác sĩ (cùng dự tiệc) mới từ Việt Nam qua - Đậu hết mấy cái USMLE1... USMLE3, đang xin thực tập ở các bệnh viện Mỹ - Tôi cười, nói ra chẳng lợi gì. Như vậy đủ thấy rằng dù con cháu VNCH mà ở với Việt cộng cũng xạo, cũng nói láo như Việt cộng.

"Gần mực thì đen, gần đèn thì sáng" cấm có sai bao giờ.


May cho cô ta là không có tôi ở đó!

Mùa xin thực tập đã qua rồi, mỗi năm chỉ có một dịp vào tháng 3 (the Match).

Cô này phải thi ba cái: USMLE 1, USMLE 2 clinical knowledge, USMLE 2 clinical skills.

Từ nước ngoài, trừ khi phải học thêm ít nhất hai năm, hầu như không thể đậu USMLE 1, USMLE 2 clinical skills.

USMLE 1 đi chuyên sâu vào y học phân tử, y sinh vật, y hóa học hữu cơ.

Cái khó là nay test này "adaptive", tức là trong 2h đầu hỏi đủ thứ, từ giờ 3 đến giờ 8 toàn xoáy vào các lãnh vực thí sinh YẾU NHẤT, càng có điểm xấu đề tài nào, càng bị hỏi nhiều về đề tài đó!

USMLE 2 CK cũng không phải là dễ, nhưng sinh viên nước ngoài còn có thể đậu.

Về cộng sản thì phải theo các thủ thuật khám bệnh đặc thù tại Mỹ, chứ cho dù là một bác sĩ xuất sắc bên Pháp, Úc, Đức qua đây cũng rớt.

Và đây là trình độ Anh văn cực cao.

Các bác sĩ Việt Nam dịch bằng chữ mấy chục năm trước khi đó còn dễ, chứ nay thì khó hơn rất nhiều và ngày càng khó.

Cô này nếu chăm thì có thể vẫn được, nhưng probability này rất nhỏ, theo tôi không tới 1% cô ta có thể đạt được, và thực tập thành công.

The Autistic, Autistic Savant và Asperger
***************************

Có một savant Toán học, hỏi ngày nào bất kỳ trong lịch sử cũng nhớ, chính xác, cộng trừ nhân chia lên tới hàng chục con số làm trong chớp mắt, nói được cả chục ngàn số Pi. Nhưng nói tới kinh tế, chính trị, xã hội, thể thao, lịch sử, là chẳng nhớ được gì, chẳng biết. Ráng học cũng không qua, học social sciences ì à ì ạch. Riêng chuyện gặp gf nói chuyện, cũng không biết bắt chuyện gì.

Còn có bà nữa, bên uni adelaide - faculty of law, IQ thuộc hàng cực kỳ cao, tui không rõ, nhưng bà có khả năng nhắc tới bất kỳ một case nào từ năm Úc độc lập về mặt tư pháp là 1901 tới giờ, hay tới tiệm tui clean chân tay, tips rất hậu, mặt như con diều hâu.

Cứ hệt như là một quyển Encyclopaedia/Bách Khoa Tự Điển về Common Wealth Law đầu thai thành người vậy.

Nhưng hỏi cái gì ngoài law thì bà bó chiếu, sơn móng tay màu nào cũng không biết làm sao cho đẹp. Ăn mặc ngoài suite đi tòa ra, thì làm ơn đừng mua đồ đắt tiền mặc, vì đắp hết lên người trông như bà điên.

Đây chỉ là các người có trí nhớ tốt, bị bệnh autism.

https://www.wisconsinmedicalsociety....tistic-savant/

Tuy họ nhớ giỏi, nhưng không biết và không thể làm gì với các con số, bản nhạc, data vô hồn đó. Có đứa trẻ 7 tuổi đã chơi cả concerto của Mozart, nhưng không 1 chút biểu cảm, như robot mà thôi.

Họ nhớ chỉ như một computer/máy điện toán, vô dụng, và trí nhớ của họ chỉ đáng giá một chiếc computer file trị giá hai xu.

Bill Gates III mắc bệnh này nhưng nhẹ hơn, gọi là Asperger's.

Ngoài chuyên môn, các người này rất kém các việc khác.

Bill Gates sau này luôn có vợ đi theo luôn luôn, nên đỡ hơn chút. Trước đó ông ta là một người bẩn tánh, cực kỳ khó chịu.

Tôi từng làm intern cho Microsoft (hè 1993, sau khi đi du học Pháp về), nơi riêng tư không nghe 1 lời nào tốt về ông này.

100% người làm thù, ghét ông ta. Hoàn toàn không có khả năng ngoại giao, ngôn ngữ cũng rất tệ, tuy là giỏi, biết, hiểu rất nhiều, nhưng không thể sử dụng trong văn nói.

Các người này đóng cửa tâm hồn họ lại, không quan tâm đến người khác nghĩ gì.

Ngay giữa cuộc họp, Bill Gates có thể ngồi nhìn trần nhà, quay quay viết chì hàng NGÀN lần quanh các ngón tay, lắc lư ghế theo nhịp điệu riêng của ông ta cho đến gần gãy ghế, hoàn toàn không quan tâm, không biết, đến gì, ai, xung quanh.

Khi làm việc, ông ta có khả năng tập trung đến hàng chục ngày không cần ngủ, và hoàn toàn đóng cửa với thế giới bên ngoài.

Mỗi lần như vậy, người xung quanh chỉ có thể bỏ đi. Chờ ông ta tự mở cửa tâm hồn trở lại.

Các người này thường chỉ là "làm phiền" chứ họ rất hiền, vô hại. Asperger's nhẹ hơn, còn có thể ra xã hội, chứ người bị autistic savant thì không có khả năng ra xã hội vì họ khép kín quá nhiều.

Bill Gates không có khả năng tự sống 1 mình, vì mỗi khi tật cũ trở lại, bất ngờ, ông ta có thể tự hại mình chết nếu không có ai can thiệp. Ví dụ cỡi cái ghế đến lúc gãy, té lăn cù. Hoặc đóng cửa làm việc 10 ngày không ra, bị đói quá, cơ thể chuyển qua sử dụng mỡ, gây acidosis trong máu, làm loạn nhịp tim chết.

Nhưng ông ta quá giàu, lo gì. Lúc nào cũng có cận vệ, nay có vợ luôn đi theo.

Cô này từng vô trại Bataan (Phi) thăm trường PASS (preparation for American secondary school), tôi từng có hình cô ta nhưng làm mất. Tôi còn nhớ khi đó cô ta là sinh viên Duke, qua đó thăm trại tị nạn. Người rất hiền, phúc hậu.

Tôi nhớ vì cô ta nói tên Melinda French. Tôi ngây thơ hỏi cô người Pháp hả. Cô ta cười, nói không phải, chỉ là tên như vậy.

Người hiền, phúc hậu, chúng ta gặp một lần là nhớ đời.

The Autistic Savant

savant-syndrome -autistic-savant

By Darold A. Treffert, MD

This website generates many inquiries about the “autistic savant,” particularly because the Academy Award winning movie Rain Man made “autistic savant” a household word. But savant skills are not limited to autistic persons, nor are all autistic persons savants. Therefore Savant Syndrome is a more accurate and inclusive term for this remarkable condition and Savant Syndrome includes some persons (about 50%) who are autistic with superimposed savant abilities, but also includes persons with other Developmental Disabilities (the other 50%) who have savant abilities as well. With that caveat, since autistic savants are a distinct subgroup in Savant Syndrome, and often of special interest, this section focuses separately on what we do know about the “autistic savant” as one important part of Savant Syndrome overall.

Raymond Babbitt, as portrayed so accurately and sensitively by Dustin Hoffman in Rain Man, certainly is the world’s best known autistic savant. While a composite character, and not based on the story of one individual, Raymond Babbitt is an accurate portrayal of a high functioning person who is autistic, with superimposed extraordinary special skills coupled with a prodigious memory. That combination of Autistic Disorder + extraordinary special abilities + remarkable memory is the “autistic savant.”

But not all autistic persons are savants. Approximately one in 10(10%) do have some special skills over a spectrum ranging from what are called “splinter skills” to “prodigious’ savants.” The latter have special skills so spectacular that they would be remarkable even if they were present in a non-handicapped persons. Savant skills also occur in other forms of Developmental Disability, such as Mental Retardation, but with much less frequency, as low as 1:2000 in a residential population. But since Mental Retardation is much more common than Autistic Disorder, and since the frequency of savant skills in that group is much lower than in persons with autism, as is it turns out, approximately 50% of persons with savant syndrome have Autistic Disorder, and 50% have some other form of Developmental Disability including Mental Retardation.



Among the 10% of persons who are autistic, there is a wide spectrum of savant abilities. Most common are what are called “splinter skills” such as obsessive preoccupation with and memorization of sports trivia, license plates, maps or things as obscure as vacuum cleaner motor sounds, for example. “Talented” savants are those persons whose special skills and abilities are more specialized and highly honed making those skills obviously conspicuous when viewed over against overall handicap. Finally there is a group of “prodigious” savants whose skills are so spectacular they would be conspicuous even if they were to occur in a non-handicapped person. There are probably fewer than 50 persons living worldwide who would meet the high-threshold definition of prodigious savants, and approximately one-half of that group would be autistic savants.



This startling juxtaposition of superiority and handicap was originally given the unfortunate name “idiot savant” by Dr. J. Langdon Down (better known for having described Down’s Syndrome) in 1887. In a series of lectures in London that year, Dr. Down described his 30-year experience as Superintendent of Earlswood Asylum during which time he was fascinated by the extraordinary paradox of superiority and handicap in the same person. He described 10 such cases including one boy who would come away from an opera with perfect recollection of all of the arias; another could multiply many-digit figures in his head as quickly as they could be written down; another lad had memorized and could recite — backward or forward — albeit with little comprehension — “The Rise and Fall of the Roman Empire,” in its entirety. There is no description in these cases that would permit a diagnosis of Autistic Disorder as opposed to some other form of Developmental Disability, but surely some were autistic.



Down made a number of observations that are still valid a century later, and are applicable to the autistic savant today. First, the skills are almost always limited to a very narrow range of special abilities: music, art, mathematics including lightning calculating & calendar calculating; and mechanical or spatial skills. This narrow range of abilities is particularly intriguing when considering the wide range of abilities in the human repertoire. Second, Down noted that these spectacular special bailees are always linked to a phenomenal memory of a unique type — very narrow but exceedingly deep — often with little understanding or comprehension of that which is so massively stored, a characteristic he called “verbal adhesion” and others have called “memory without reckoning”. Third, Down noted that his cases were limited entirely to males. While not that stringent, over time the actual male:female ratio has turned out to be approximately six males for every female savant.



The term “idiot savant” has largely been discarded now, appropriately, and has been replaced by Savant Syndrome. Actually that original term as used by Down was a misnomer since almost all reported cases occur in persons with IQ of 40 or over. In Down’s time the word “idiot” was an accepted scientific classification for mental retardation with IQ below 25 and he combined that term with the word “savant” derived from the French word “savoir” which means “to know” or “knowledgeable person.” The condition of Early Infantile Autism, however, was not described as a separate entity until 56 years after Down’s original description of savant syndrome. In 1943 Dr. Leo Kanner carefully and accurately described, and named, a condition he called Early Infantile Autism now generally referred to as Autistic Disorder, and sometimes just as autism. Autistic Disorder is not a single entity and is more appropriately described as a group of disorders, with a variety of etiologies all with the final common path, cluster and constellation of symptoms we now call Autistic Disorder or autism. Among that group of persons with Autistic Disorder, approximately one in 10 have some savant abilities on the spectrum from splinter skills to prodigious savant. These special skills are superimposed, or grafted on to, the Autistic Disorder. Along with phenomenal memory, as described below.



The skills in the autistic savant continue to be seen within a curiously narrow but remarkable constant range of human abilities: music, usually piano and almost always with perfect pitch; art, typically drawing, painting or sculpting; lightning calculating, calendar calculating or other facility with numbers such as computing prime numbers; and mechanical abilities or spatial skills. Unusual language talent — polyglot savant — skills have been reported but are very rare. Other less frequently reported special skills include map memorizing, remarkable sense of direction, unusual sensory discrimination such as enhanced sense of smell or touch, and prefect appreciation of passing time without knowledge of a clock face. A conspicuously disproportionate number of musical savants through this past century, and at the present time, are blind and autistic, demonstrating a curiously recurrent triad of blindness, autism and musical genius.

In most autistic savants a single special skill exists; in others multiple skills occur. The skills tend to be right hemisphere in type — nonsymbolic, concrete, directly perceived — in contrast to left hemisphere type that tend to be more sequential, logical and symbolic including language specialization. To the extent imaging studies such as CT, MRI or PET have been carried out, savants, and particularly autistic savants, do demonstrate left hemisphere damage, with presumably, right hemisphere compensatory function. This left hemisphere damage can be from a variety of prenatal, perinatal and postnatal causes described in detail elsewhere on this Web site. It is postulated that this left hemisphere damage is coupled with corresponding damage to the higher level cognitive (cortico-limbic) memory circuitry with compensatory take over of lower level (cortico-striatal) so-called “habit” or procedural memory. This accounts for the linking of predominantly right brain skills with habit memory so characteristic of autistic savants and savant syndrome more generally. In addition to this idiosyncratic brain circuitry, intense concentration, practice, compensatory drives and reinforcement by family, teachers and others play a major role in developing and polishing the savant skills and memory linked so characteristically and regularly in the autistic savant.



CT and MRI scans, impressive as they are, only document brain structure. The real future in unlocking the dynamics and circuitry of savants, and indeed Autistic Disorder itself, will come from PET and SPECT imaging which map brain function, not just it’s architecture. Increasingly in Autistic Disorder, more and more evidence of left hemisphere dysfunction emerges, and in savant syndrome such left hemisphere dysfunction in likewise increasingly evident, and implicated as an important explanation of savant abilities. There has been only one SPECT functional imaging study reported thus far on an autistic savant, in this case an 11-year-old autistic artist, D.B. That study showed a distinct abnormality in the left anterior temporal area of the brain. What is so striking about that finding is that it mirrors exactly another recent, far-reaching discovery about savant abilities. Dr. Bruce Miller, a San Francisco neurologist, has described 12 cases now of new savant abilities emerging in elderly, previously non-disabled persons as a particular type of dementia (fronto-temporal dementia) proceeded. The SPECT abnormality in these patients was identical to that of the childhood autistic savant. This finding of new savant abilities emerging as a dementia proceeds raises profound questions about hidden potential v a little Raymond Babbitt — perhaps within us all. All of these findings and their significance are described in much more detail in other sections of this Web site.

There have been a number of autistic savants who are quite well known and, because of their extraordinary talent, have had considerable international recognition. Some of these such as Richard Wawro, and Tony DeBlois have special sections on this web site. Several others such as Ellen are described in detail in my book, Extraordinary People. Stephen Wiltshire has three books of his own published, one of them a national best seller in England, about him, and his remarkable drawing ability. Nadia was described in detail in a book by Dr. Lorna Selfe. “The Twins”, the calendar calculators, have been the subject of a number of scientific articles and book chapters. In addition to calendar calculating, they remember the weather every day of their adult life, and are able to compute prime numbers still in the absence of even simple arithmetic skills. And then, of course, there is Raymond Babbitt who all the world now seems to know.

But there is more to autistic savants than the scientific interests of brain circuits, neurons and hemispheres. Embedded in the lives of these remarkable people as well are the human interest stories about the power of love, belief, and caring in the families, caretakers, therapists and teachers that surround the savant, in first discovering, then appreciating, then helping to actualize and realize the savant’s full potential beyond deficits. Rather than fearing some dreaded tradeoff of these special gifts as the price of training and teaching the savant broader communication, social and daily living skills, these remarkable abilities can themselves serve as what I call a “conduit toward normalization” without loss of those unique talents. The century old debate of whether to “train the talent” or “eliminate the defect” can be convincingly answered now. Training the talent can in fact help ameliorate or lessen the defect. There are now compelling and inspiring examples of such useful application of special skills toward normalization in the classroom, in the workplace, and the home in a number of well known autistic savants, some of whom are mentioned above.

Until we can understand and explain the savant, we cannot fully understand and explain ourselves. For no model of brain function, including memory, will be complete until it can fully incorporate and account for this amazing condition and its remarkable manifestations. And no conclusions about human potential can be finalized either until we fully explore the ramifications of what is seen in the savant. Serious study of savant syndrome, including the autistic savant, can propel us along further than we have ever been in understanding, and maximizing, both brain function and human potential.
