Fact: The shear modulus of the human brain matter is 1680 Pa.
Question: Why /the hell/ does Wolfram Alpha know this??
Seriously. Like, somebody took a sample of human brain and actually
measured how hard you can squish it? WHY?!?

Forensics? Better evaluation of crash test results?

I was actually looking for the number of neurons in a typical human
brain. I guess my query wasn't specific enough. Instead, I got a list of
parameters including "Poisson's ratio", "specific heat" and density of
the brain. (Why the *hell* would you measure the brain's specific heat??)

Hmm, yes, that's about the only sane explanation I can think of...

BTW, some times japanese manga comes up with some interesting thoughts. I read
in Blade of the Immortal a suggestion that europeans had quite a better grasp on
medicine as opposed to the traditional chinese medicine because they had quite
good knowledge of the human body and its inner workings for all the centuries
worth of painful and barbaric tortures and death penalties. Europeans were
making surgery while chinese were still drinking bitter tea.
I'm sure there was plenty of torture in china too, but while europeans were
cracking open bodies and letting them rot in public places during the dark ages,
china was in the height of a sophisticated civilization. Death penalties were
usually carried out quickly rather than in agony.

I heard QI assert that the invention of china held China back
technologically for several centuries. The gist of it being that since
they had china cups to drink out of, they didn't develop glass, so they
didn't have sophisticated optical lenses, nor high-temperature furnaces
for smelting iron, etc. Or something like that. (I can't remember off
the top of my head whether it was china, paper or tea, but it was
something innocuous like that.)

Making brain surgery simulators that behave like the real thing.

an interesting conjecture, no doubt. OTOH, the chinese discovered powder.

Interesting hypothesis, but I don't think it's the real explanation.
On the contrary, medicine in the middle ages was pretty much stagnant
because the church had forbidden the study of corpses. It was not until
the age of enlightenment, when science successfully separated itself from
the church that people got to investigate how stuff really works and things
got to progress forward.

Actually, it was often worse than that. A lot of stuff had to be
"reinvented", because, while Galen had come up with a lot of instruments
and methods, those where declared, by the same church, illegal, as they
did with any else not, "approved by them, or invented by 'their'
scholars". It didn't just stagnate, in some respects it went backwards.

Apparently you can afford your own dictator for less than 10 cents per
citizen per day.
