If you want to spend $100 learning why food cooks get a copy of Myhrvold's
Modernist Cuisine: The Art and Science of Cooking. I refuse to pay but I
read online articles about some of his stuff, and when the books came out
they were all over the food shows lol. Insanely fascinating stuff for a
foodie, makes me wish I had could have gone from Microsoft CTO to playing
with liquid nitrogen and gas chromatography. Skipping the Microsoft part
lol. Check out his website, he's moved on to snowflakes now and has a truly
mad scientist approach to photographing them in incredible detail.

Axel,
Admittedly, that particular concept is difficult for even educated people to
grasp, after all, even a tiny droplet of scalding hot water would burn you
(albeit a tiny bit). Nevertheless, I would think that the fact that we have
geostationary satellites would prove that we can go through the thermosphere
without melting. To be honest, it is amazing that they choose such a nerdy
reason not to believe that we could get to the moon. I would think that that
kind of person wouldn’t believe in the thermosphere in the first place
because it is outside their understanding, and if they don’t understand it,
they don’t believe in it.
But in the case of plate tectonics, we are talking about geology
professionals writing a book on geology, yet refusing to see all the
evidence for plate tectonics that was available by that time, and still
refusing to believe it because they did not understand the mechanism for it
to happen. I don’t understand how food cooks, but I have seen it cooking,
and don’t deny that it happens just because I don’t know why it happens.

are that hot and subsequently move at very high velocities, but there are
not enough of those to harm a space ship!
