Albert Einstein is the most recognizable and the most famous scientist.

He embodies the essence of genius, and although he passed away 66 years ago, Einstein still ranks among the top earning deceased celebrities, along with the most famous actors and rock stars.

He also derived the world’s most famous formula: E = mc2

Therefore, when a handwritten letter appeared at the auction, on which Einstein wrote the famous formula with his own hand, it was logical that it should be sold for a huge amount.

And so it happened – the letter was Einstein’s fourth letter, sold for more than $ 1 million.

The only known particular sample containing the famous equation E = mc2, a one-page letter that Einstein wrote to the Polish-American physicist Ludwik Silberstein on October 26, 1946.

It was ultimately sold for $ 1,243,707 at RR’s Boston auction.

The letter reads (translated):

“Your question can be answered by the formula E = mc2 without any erudition. If E is the energy of your two-mass system, E0 Is the energy of the masses when they approach an infinite distance, then the mass defect of the system E0 – E / c2

“In your case (E0 – E) pot = km2 / r. However, due to kinetic energy, the total energy deficit is half as much, in accordance with the virial theorem. Therefore, if is the mass of the complete system, 2m – M = 1/2 k / s2 m2 / r in the first approximation, that is, if we do not take into account the effect of the finite mass radius.

I am convinced that this (or the formula corrected for the radius of the masses) cannot help shed light on the atomic constants. To do this, you first need to have a theory that contains the correct unification of gravity and electricity. “

According to archivists for the Einstein Papers Project at the California Institute of Technology and the Hebrew University of Jerusalem, there are only three known examples of the famous Einstein equation, and none of them are in private hands. This, the fourth sample, was presented to the public for the first time at auction.

The auction featured many historically significant items from the personal collection of Ludwik Silberstein, an outstanding mathematician and physicist who wrote one of the first English textbooks on the theory of relativity.

The collection included four letters from Einstein, twelve handwritten letters from Max Planck, and correspondence from other Nobel laureates such as J.J. Thomson, Hendrik Antun Lorenz, and Albert Michelson.
