Is it just me, or is lots of physics memorabilia being bought and sold these days?

Last week, items associated with Richard Feynman fetched nearly $5m at  Sotheby’s in New York. His Nobel prize medal alone sold for almost $1m.

On Tuesday, a handwritten letter by Albert Einstein calling the Bible “a collection of primitive legends,” sold for nearly $3m at Christie’s in New York. Sent in 1954 to the philosopher Eric Gutkind, the 1.5-page “God letter” is written in German and contains a number of ruminations on religion.

Next up is the Nobel prize medal and citation won in 1924 by Manne Siegbahn for his work on X-ray spectroscopy, which will be auctioned in Boston on 13 December. The sale will be conducted by RR Auction and the reserve price is $10,000. As you can see in the above image, it is a beautiful collection of objects.
