Today is the 150th anniversary of Hilbert’s birthday.
Hilbert is one of the mathematicians I admire the most. I believe I first learned about him while in High School, through “Higher Geometry” by N.V. Efimov. My copy of Reid’s “Hilbert” is one of the first books I bought when I arrived in the States (in 1997).
Here is a link to the reprint in the Bulletin of the AMS of Mathematical Problems.
I would love to have a poster sized copy of the picture above. Springer sold them years ago, but now they seem impossible to find.
