Freeman Dyson

This article is pretty well-balanced for the New York Times, and very interesting. This particular paragraph had me chuckling:

At Jason, taking problems to Dyson is something of a parlor trick. A group of scientists will be sitting around the cafeteria, and one will idly wonder if there is an integer where, if you take its last digit and move it to the front, turning, say, 112 to 211, it’s possible to exactly double the value. Dyson will immediately say, “Oh, that’s not difficult,” allow two short beats to pass and then add, “but of course the smallest such number is 18 digits long.” When this happened one day at lunch, William Press remembers, “the table fell silent; nobody had the slightest idea how Freeman could have known such a fact or, even more terrifying, could have derived it in his head in about two seconds.” The meal then ended with men who tend to be described with words like “brilliant,” “Nobel” and “MacArthur” quietly retreating to their offices to work out what Dyson just knew.

And this comment got to me too:

His older sister Alice, a retired social worker still living in Winchester, remembers how her brother “used to lie on the nursery floor working out how many atoms there were in the sun. He was perhaps 4.”

Dyson is a genius, but also a contrary and original thinker and, it seems, of a kind that we just don’t see so many of now. Where are the upcoming people like Einstein, Feynman, Oppenheimer and Bethe now? I wonder why we don’t see them? Maybe something to do with politicized consensus science? Being brilliant and original doesn’t really work in the groupthink that so much science has become.

Update: And here are some of his heretical thoughts…

Antimatter

I just received an email from ‘spaceoperaghost’:

‘Thought this might interest you if it hasn’t been emailed or otherwise brought to your attention already. CERN trapped antimatter! I suppose it’s too soon to start demanding warp drives and clean energy, but it’s still awesome.’

Yeah, I think we can safely assume that this is of interest to me.

Geneva, 17 November 2011. The ALPHA experiment at CERN1 has taken an important step forward in developing techniques to understand one of the Universe’s open questions: is there a difference between matter and antimatter? In a paper published in Nature today, the collaboration shows that it has successfully produced and trapped atoms of antihydrogen. This development opens the path to new ways of making detailed measurements of antihydrogen, which will in turn allow scientists to compare matter and antimatter.

Here’s a link to the article at CERN, and here’s the press release. It’s all rather dry, but then, I have become rather tired of ‘scientists’ who step over the line into politics, produce self-aggrandizing press releases and start making ludicrous predictions based on their work.

Update:
CERN created the first nine atoms of antihydrogen in 1995, and then started to produce atoms in large quantities in 2002, as part of the ATHENA and ATRAP experiments. This is the first time that scientists have been able to trap antihydrogen atoms for a long enough time to study them, keeping them at 9 degrees kelvin (-443.47 degrees Fahrenheit, -264.15 degrees Celsius), suspended in a magnetic field inside this Ghostbusters-style machine. The other reason why this is an important step is its potential to solve our need for unlimited energy. When antihydrogen touches matter—as shown in the image above—it releases a huge amount of energy. Many scientists speculate that antimatter may be the key to provide unlimited power capable of driving machines that are unthinkable right now. Eventually, it could be the stuff that could power new engines capable of taking us to the stars at near-light speed.

Um, so why the present press release?

More About the Bookmarks Competition.

Now, first off, I’m not trying to opt out of the responsibility for judging all of these. This bookmark competition itself, just like the art competitions before it, the pictures of people’s collections and that ‘who reads my books’ thing I ran a while back, is me trying to make this blog more ‘inclusive’. I want people to join in, have a bit of input, and this to not be all about me standing on a pedestal and prating into a vacuum.

So, to that end, how would you all feel about YOU being the judges. When the time comes I can set up a poll here from PollDaddy and all of you reading this can decide. In fact, I’m going to do one now.

Incidentally, since the number of people reading this blog had about doubled over the last year, how about some more additions to ‘Who Reads My Books?’ As before, I want a short biog plus a photograph or two.
