>>The month of July, 2019 will be a bumper one for the number of landmark scientific artifacts heading for auction. Three Christie’s auctions and a Sotheby’s auction have such a stellar array of scientific documents, manuscripts, tablets, seals and artifacts that we thought it worthwhile documenting them, even though in some cases, they are estimated to sell for quite affordable amounts.<<

Early maps, books, etc., good description of each; you just need a little cash to add them to your collection.

That is quite a startling collection.

On the “scribblings” by Neils Bohr i recognose three famous experiments. The double slit experiment. Maxwell’s demon, and dropping weights in an elevator. It looks like a teaching, as in “quantum mechanics for dummies”.

I’ve seen another auction that made me more jealous, most of these are books rather than handmade or examples of nature. And the prices put me off.
