BOSTON (WBZ NewsRadio) —A Boston based auction house is about to find a price for a priceless letter penned by Albert Einstein.
The letter contains the only handwritten example in private ownership of the world's most famous equation, "E=mc2."
The one-page letter shows the equation in the first line and according to Boston based RR Auction it translates to, "“Your question can be answered from the E = mc2 formula, without any erudition. If E is the energy of your system consisting of the two masses, E0 the energy of the masses when they approach infinite distance, then the system’s mass defect is E0 – E / c2.”
The letter was written by Einstein in 1946 to the Polish American physicist Ludwik Silberstein. The equation, of course, is the theory of relativity.
RR Auction values the letter at about $400,000. They're also auctioning off other Einstein letters, in which the theoretical physicist writes out gravitational field equations and comments on the rise of Adolf Hitler, as it was happening.
Bidding starts on Thursday at $25,000 and ends May 20.
