On a recent visit to the Royal Observatory Edinburgh I was shown the amazing Crawford Collection.
This assortment of historic science texts includes amazing tomes by Galileo, Copernicus and Newton - to name just a few.
It was amazing being able to actually thumb through first editions of the Principia and De revolutionibus - surely two of the most important science books ever written.
I can't even imagine how much money some of these books are worth.
Here's the video for Backstage Science.
Keep an eye out for the death mask... doesn't it look like Robin Williams!!!?
