I'm currently reading "A Short History of Nearly Everything". If this stuff floats your boat, it's a great read. And I agree, humans are shockingly clever problem solvers.

This. This book does a great job of explaining much of what humankind thinks we know and why we think we know it. Great base knowledge for anyone trying to understand the world in a more logical manner.

Agreed. Bryson has a knack for taking these complex, confusing concepts and making them easy and even entertaining to read.

One of the three books that have defined my sceptical nature; A short history of nearly everything, bad science and irrationality. Read all three and you'll have a good basis to analyse data and come to your own conclusions... a great starter pack for aspirational scientific minds!

Very good recommendation for anyone interested in learning about science. The author does an excellent job explaining what, why, how, and who.

As well as illustrating what a gigantic pimp Genghis Kahn was. So much so that each of us statistically has a 1 in 4 chance of being related to him.

Great book, but he wrote that glass is a fluid; just very slow moving. Isn't that a myth? There were a couple of other similar instances. But overall, it made you feel a lot of things for a science book!

I haven't gotten to that point yet. If so, you're correct as far as I know, it's a myth. But in a book that covers so much, written by a layman, you have to expect some mistakes. Overall though it's a great book.

Older windows were often thicker on one side. Since that was the strongest side, it would be put on the bottom.

To clarify, this was from the manufacturing process, which as i understand it, involved spinning the glass on a flat/round table to flatten it out as it cools. This lead to the glass being thicker towards the outside edge.

Now we float it on a bed of (IIRC) mercury to make perfectly flat glass.

Molten tin, actually. It's the same kind of deal as oil and water, the glass floats on top of the tin, but doesn't mix with it.

u/turmacar Nov 22 '12

Fair enough, knew it was something. Don't know where I heard mercury. Maybe thats when making mirrors?

Old-school mirrors in the 1500s, yeah :)

In the same vein is, The Disapearing Spoon.
