A team of scientists led by Mark Raizen at the University of Texas at Austin had the gumption to take on Einstein. And according to their new paper in Science, they won. The point of contention? The lovechild of statistical mechanics and thermodynamics: Brownian motion.Encouraging. Shows that what one generation considers "immeasureable", gets measured by another generation...

There's something funny about the press release, don't you think? Normally, when people say "take on Einstein" the implication to me seems to be that the person is challenging relativity. But in this case, it's a completely different paper, if I'm not mistaken. It's a problem with Einstein specifically, I suppose, since he is so famous for that one and when one speaks of "challenging Einstein" is almost sounds equivalent to "questioning relativity." It even seems like whoever wrote that press released was deliberately creating that understanding.

Don't Porsche tires display Brownian motion? :)

It doesn't imply that to me, nor, I'm sure, the writer. Einstein did a lot of stuff, and made a lof of statements about his interests. (Wikiquote (http://en.wikiquote.org/wiki/Albert_Einstein).) Being a clever fellow, he said a lot that was right. And, not being a god, he said a lot that was wrong. My only reaction when I hear someone taking on Einstein is to wonder what particular statement of Einstein they might have an issue with.

There was quite a few things that /Many/ scientists of Einstiens day thought were immeasuable. It was felt that there would never be a way to actually produce an image of an atom, or of molecules and thier bonds. Yet both those have now been done.

Why does every one pick on Einstien? Was it his wild hair?

Nothing in Arxiv yet.

It strikes me that their measurements actually confirm Einstein's main points. They only refute his feeling, correct at the time that he made his statement, that the measurements could not be made in practice.

I sat an English exam once in which the essay question was "The essence of drama is conflict. Discuss."
Journalists and bloggers are aware that people like to read about conflict, particularly about conflict with famous people, and especially about conflict with iconic famous people. Refutation of Einstein! makes "better" copy than Brownian motion measured!

My old boss used to call this sort of thing "over-egging the pudding".
