Crazy Al

So I was chatting with a friend of mine the other day about science and scientists, and in particular what on earth we theoretical physicists actually do.

She (mostly jokingly I think) said we’re really all a bit weird, just sitting around thinking about quantum physics all day. einstein_imagesI tried to begin to explain that we don’t sit around thinking about quantum mechanics all day any more than a tailor sits around all day thinking about needles. (Or how many angels or demons can fly through the eyes of said needles at the same time.) No, we’re mostly getting on with using the needles in the making of new suits and so forth. (To continue the allegory.)

But I did not get to that analogy, because another thing came up. She went on to say “…like Einstein, with crazy hair…”, to invoke her primary example of the crazy quantum scientist. Now, given that she was talking to me (er… no crazy hair, in case you are wondering), she was clearly joking, but in my view, at the core of all that is a serious image problem that science has to deal with – bizarre cliches about who we are and what we look like. So I thought I’d point something out.

The most famous image of the crazy/eccentric scientist is largely based on a lie (or […] Click to continue reading this post →

Terry Gross interviewed Scott Patterson and Ed Thorp on NPR’s Fresh Air. I heard it yesterday. It was very interesting to listen to Thorp in particular, a mathematician, describing his curiosity about how to construct a system for beating various gambling games, and going from there to the stock market, in effect becoming one of the earliest of the “quants”,

Thorp and the people who use such systems have come to be known as “quants” — it’s a reference to the quantitative-analysis techniques they employ — and their stories are told in Scott Patterson’s new book The Quants: How a New Breed of Math Whizzes Conquered Wall Street and Nearly Destroyed It.

You can hear the interview here, and read an extract from the book. Very interesting are the questions about what they think really went wrong in the market crash of […] Click to continue reading this post →
