Don’t study engineering or science

Thomas Friedman writes today in his column, One Country Two Revolutions

if one result of the downsizing of Wall Street is that more of America’s best and brightest math and physics students decide to go into science and real engineering rather than financial engineering, the country will be a whole lot better off.

The rest of the article is a glowing account of Silicon Valley and some of the inspiring people he wants us to emulate.  Just for fun, I looked up the education histories of the people he cites:

  • Alan Cohen, VP at networking company Nicira (MBA, MA Int’l studies)
  • Scott Wilson, designer mentioned in Fast Company (B.A. Design)
  • Alexis Ringwald, founder of an education startup (B.A. Political Science)
  • Marc Benioff, CEO of Salesforce.com (B.S.B.A. Entrepreneurship)
  • Jeff Weiner, CEO of LinkedIn (B.S. Economics from Wharton)
  • Jagdish Bhagwati Professor at Columbia is of course is a BA Economics.

(By the way, Mr. Friedman himself has an undergraduate degree in Mediterranean Studies)

Not a single one of the people he praises is an engineer or scientist!

Like I said after watching the education movie 2 Million Minutes:  Science and engineering are important, but by themselves they are technical skills, like welding or car repair, that can be mastered by anyone with some discipline and training.  You need to be much smarter than that. I’m reminded of the common entrepreneurial wisecrack: “If I need an engineering degree, I’ll hire one”.

China and India have plenty of engineers and scientists.  To compete in the future, we need innovators and risk-takers, along with a culture that encourages people to try new things, even things the “experts” and regulators think are too risky or likely to fail.  The future belongs to people with curiosity, open minds, willingness to change, an ability to empathize with people of different backgrounds, work well with others, and a society with enough flexibility and freedom to allow for many ways of getting there.

If science and engineering are your passion, by all means go for it. But if you (or your kids) are studying it just because experts like Thomas Friedman say you should, then you’re missing the whole point.

What happened to me?

I just spent eleven nights in the hospital – four of them in ICU. I’ve always been a pretty healthy guy. What happened?

The short answer: a bowel obstruction – a kink somewhere in my intestines that kept food from passing through – plus aspiration pneumonia, which I contracted shortly after they inserted a three-meter tube through my nose and into my tummy.

Exactly two weeks ago, I boarded a plane to return to Beijing feeling a little tummy ache – I thought it was some Mexican food I’d eaten – but the high altitude of the flight – which tends to bloat the internal organs—apparently worsened the situation enough that I was pretty sick by the time I arrived, unable to hold food or water. I pulled myself together enough to complete my MacWorld keynote address, and then headed straight to a clinic for treatment.

Those horizontal lines are not good: it means something is blocking the normal passage of liquids.

Bowel obstructions are nearly unheard of in younger people, but in my case the cause is clear: abdominal surgery as a child left bits of scar tissue that accumulated over the years enough to occasionally wrap around the intestines. Although full obstructions can be somewhat common with a history like mine, I lasted nearly thirty years without trouble, and I’m hopeful that this time was just a fluke that won’t bother me again.

Treatment is pretty straightforward: doctors insert a tube to let the pressure off the obstructed area, and wait for it to heal naturally. Doctors try hard to avoid surgery – after all, it’s the surgical scar tissue that causes the problem in the first place –but it’s always a backup option in severe cases. I’m recovering fairly well, so that doesn’t seem to be a necessity for me.

The pneumonia, meanwhile, made my situation worse than it might have been. We’re not sure how I contracted it. I had a bit of a cold the previous week – did my weakened condition cause it to flare into something worse?  Or, maybe in the process of inserting the tubes, something in my throat disturbed the lungs somehow and tipped me into a much worse situation?  Either way, this was quite a scare and it necessitated the ICU, a week of breathing with an oxygen mask, and plenty of antibiotics, which I’ll need to continue taking for several more weeks.

It’s been two weeks and although I’m much improved, I’m not out of the woods yet. I’m recuperating at home, which of course is much better surroundings than in the Chinese hospital I left. This week is a Chinese holiday, and while it’s a bummer that I can’t get out and enjoy the vacation, I’m not missing any work either. For now I’ll just continue this way, taking it slowly until I’m back to my old self.

[Book] 1493

 

The New World was created, not discovered, says Charles C. Mann. The impact of Columbus’ historic trip was felt worldwide, ushering in the Age of Globalization that we know today. Nearly everything, worldwide, changed so much as to make the pre-Columbian world unrecognizable. Can you imagine Italy without tomato sauce? Ireland without potatoes? Georgia without peaches?

I was surprised to see that this book is as much about China as it is about America or Europe. In fact, the author did much of his research in China. This is more obvious than it seems: after all, trade with China was the ultimate goal of Columbus and the generations that followed him.

There is a lot to this book and I know I’ll think about it for many years to come. If I had more time or motivation, I’d write a proper summary, but in these days of super-short tweets and instant-access Google, let me just summarize a few of the more interesting takeaways, since I know I’ll likely want to refer back to these ideas later:

  • Columbus’ largest ship, Santa Maria, ran aground on his first voyage, so he had to leave 38 people behind. When he returned eleven months later, they were all dead—the result of conflict with the locals (called Taino).
  • The non-human travelers to America were at least as important as the explorers themselves: bacteria and viruses caused epidemics, insects destroyed native crops.
  • Earthworms were unknown in America until the Europeans arrived. Imagine the soil without them, and all the consequences on mulch and the types of trees possible and much, much more.
  • Trade with China began in the 1560s in Manila.
  • The period of unusual cold known as the Little Ice Age, from 1550 to 1750, may have been caused by the end of wide scale forest burning by native Americans.
  • The Virginia joint-stock corporation shipped seven thousand people to Virginia between 1607 and 1624, of whom eight out of ten died.
  • Tobacco saved England’s New World investments: by 1680 it was exporting 25 million pounds per year.
  • Nicotine addiction was rampant worldwide by the early 1600s: in 1635 the khan Hongtaiji prohibited tobacco. Guangxi Chinese were making tobacco pipes by 1549.
  • The flintlock rifle, which first became available in the late 1600s, was the first weapon that Indians recognized as superior to the bow. John Smith’s matchlocks didn’t work in wet conditions and required a tripod for accuracy.
  • Malaria killed untold numbers of people in the Americas and was common even in New England. Africans, with their “Duffy antigens” were immune and became ideal laborers as a result.
  • One reason Zheng He’s historic travels from China weren’t followed up: he never encountered a nation richer than his own. “For the same reason the United States stopped sending men to the moon – there was nothing there to justify the costs of such voyages”.
  • The Ming prohibited all private seagoing vessels in 1525 (but reversed the order fifty years later in order to trade with Europeans in Manila).
  • Wokou (倭寇) Japanese pirates were a serious threat to trade.
  • Yuegang, near modern Xiamen, was one of the world’s most important ports in the 1600s.
  • By the 1570s, 90% of Beijing’s tax revenue came in the form of silver coins.
  • Potosi, Bolivia’s “mountain of silver” was discovered in 1545. By 1611, its population of 160K was as big as London or Amsterdam.
  • The Qing dynasty enacted a program of smallpox inoculation.
  • “Part of the reason China is the most populous nation is the Columbian exchange” (p177). New, highly productive crops like sweet potato and corn enabled cultivation in otherwise impossible areas.
  • For 167 days in 1925 two Polish researchers lived on potatoes with butter and reported no health problems. [p197]
  • “Roughly 40 percent of the irish ate no solid food other than potatoes”. [p209]
  • Tenochtitlan fell on August 13, 1521.
  • P.312 : 57% of the early descendants of Conquistadores tracked were of Indian descent.
  • P.313 In 1640 there were 3x as many Africans as Europeans in Mexico.
  • P323: Katana-swinging Japanese helped suppress Chinese rebellions in Manila in 1603 and 1609. When Japan closed its borders in the 1630s Japanese expatriates were stranded wherever they were.
  • P.359: English Puritans launched two colonies, one at Plymouth and another off the coast of Nicaragua in 1631.

Like I said, very interesting and there’s a lot more. If you like history in general, or if you’re looking for a fresh take on China, this is definitely worth reading.

The Chinese Twitter (English version)

Now available on the US App Store: Sina Weibo 微博 download here: http://itun.es/igk6zp then follow me at http://weibo.com/2140336255 and see why 200M users like it.

Note: to create an account you'll need some rudimentary knowledge of Chinese (either from something like Google Translate or from a helpful friend).  I assume they're working on an English version of the web site too of course.

Books versus Conversations

There are two major ways we humans express ourselves: books and conversations.

A well-written book has the advantages of being an exhaustive treatment of a complex topic, but sometimes the length or completeness of a book is inappropriate. “I just asked him for a simple reply to my email but he wrote a novel instead.” If that novel wasn’t exactly what I was looking for, the effort to understand and then respond to it is greater than whatever result I’m hoping to get back.

A conversation, on the other hand, is tentative and ephemeral. If I speak poorly, you can ask me for clarification; if I make an error, you can correct me. A conversation, by definition, is a collaborative act. A one-sided conversation is an oxymoron.

Some conversations are just idle chit-chat, a way to pass the time; but a good conversation, like a good book, leads somewhere, bringing you to an ending that feels like progress on the road of life.

Social networking services are moving us more to a conversational lifestyle rather than a book-like consumption lifestyle. A blog isn’t much fun if nobody responds to what I write; Twitter and Facebook resemble blogs except they’ve made the interactivity—the conversational aspects—much easier.

A book is the distillation of a long series of conversations. A well-written book has value because it saves the reader the time it would have taken to have the conversations that led to the conclusions in the book.

Book Drop: No Books, Please

Facebook’s addicting even if you don’t admit it

It’s a few minutes before the next meeting. Or maybe it’s right before dinner is ready. Or there’s a commercial on TV. Or it’s time to go to bed. Or get up.

What’s your first thought at each of these moments? Check Facebook! It’s a continuous stream of what’s happening among the people and interests in my life, and it gets more and more useful every day. No wonder more than 100 million Americans log in daily. It’s the most popular web site in the world, and it will keep getting more so.

Many of my friends are silent on Facebook, but I know they’re there, lurking, watching, reading all of my updates. Even the shy ones, or those who think they have nothing themselves to say…they still watch.

Japan’s Mixi social networking service (of which I am a member, though rarely active) has a great feature that lets you know when somebody has visited your profile. I wish Facebook had something like that. I bet we’d all be surprised – impressed – at the number of our silent friends who actually watch everything we do.

Hard to know for sure

I keep running into this problem of the limitations of knowledge. Today, a professor friend of mine reminded me how the one thing you take away from earning a PhD is how little you know of your field of study. We were discussing the old saying that after your first week in China you’ll feel like you could write a book about the place; after a year you’ll think you could write a magazine article; after a few years you give up writing anything.

The Useless Tree Blog discusses (via China Law Blog) a recent interview with Chinese official Wang Qishan claiming that China is only understandable to insiders like himself, but my first thought is “what does it mean to understand in the first place.” Does anybody really know?

Then there’s Peter Norvig’s excellent review of a recent remark by Noam Chomsky dismissing the use of statistical techniques in linguistics. Chomsky apparently thinks real scientific understanding requires more than a statistical analysis of a bunch of data—you have to synthesize that knowledge, presumably into simpler, fundamental rules that describe the Universe. That’s super-hard, and except in Physics almost always turns out to be an approximation anyway.

This is just restating the problem identified by Hayek in The Use of Knowledge in Society and by countless others who reflect on the limitations of what we know.

Society gives too much credit to people who appear to know, but I think self-confidence is no substitute for understanding.
