Richard Feynman’s Nobel Prize Sir Isaac Newton outlined his three laws of physics in his seminal Philosophiæ Naturalis Principia Mathematica (“Principia”). Published in 1687, the Principia is still regarded as one of the most influential books in physics history. More recent nuclear history materials have gone to auction, too, including a “The astounding prices for which these pieces of physics history have sold brings to mind questions of value. By: Hannah PellRR Auction, an auction house based near Boston, Massachusetts, recently sold one of Albert Einstein’s hand-written letters for $1.2 million. Arguably one of the most well-known physics equations ever, well, you can easily imagine why someone would just have to have it.This million-dollar document made me wonder: what other notable pieces of physics history have been auctioned for a pretty penny?
