A handwritten letter by Albert Einstein which is rare for containing his famous E=mc? mass-energy equivalence formula has gone on sale for the sum of?GBP 282,000 (approx. Rs 2,91,94,106), according to this website.
The letter is dated October 26, 1946, and is one of only four known examples of the formula having been written by Einstein. It is part of correspondence to a fellow researcher, telling him a question could 'be answered' using the formula.??
According to Boston-based RR Auction, the letter, which is one-page long and blind stamped on a personal Princeton letterhead will be auctioned in a time sale which will end on May 20.?
According the auction site, the letter will have a minted Non-fungible Token (NFT) and a 5D Biometric Art Passport powered by ARTMYN which ensures that the original manuscript is unforgeable while allowing the owner to monitor the evolution of its condition over time. It also serves as a digital portfolio preserving all associated documentation.?
Einstein composed the correspondence on a Princeton University letterhead in German and was written to Polish-American physicist Ludwik Silberstein who had previously disputed part of Einstein's theory of general relativity.?
In response to Silberstein¡¯s query, translated into English, Einstein's response read: ¡°Your question can be answered from the E = mc? formula, without any erudition,¡± reported?Daily Mail.
¡°If E is the energy of your system consisting of the two masses, E? the energy of the masses when they approach infinite distance, then the system's mass defect is E? - E / c2,¡± he continued.
