JF Ptak Science Books Quick Post
This slender 1946 Dutch publication proved a little irresistible–the cover looked very loud, very red, and very accelerating-y, and was the only thing about the booklet that I could understand, though I really don’t understand that, either.
I went over to Google Patents to see what a “Mars” search might unveil, and it lead me not necessarily logically to the following patent, which seems to me to be quite a playable astronomy game, with all of the necessaries found in the text of the document. I’m not so sure that the game would be “fun” per se, but, well, it could be played. And perhaps someone might learn something from it. [Source: U.S. Patent and Trademark Office, here.]
