RR Auction in Boston, USA released new news on the 20th. An autographed letter from Einstein was auctioned at a sky-high price of US$1.243707 . The famous mass-energy equation E=mc² was recorded on it. .
Naijatechnews learned that the letter was written by Einstein to Ludwik Silberstein, an American physicist, and it recorded an idea of Einstein at that time, that is , the relationship between energy, mass, and speed E=mc² .
Wikipedia shows that E=mc² is a theoretical physics formula describing the relationship between energy (E) and mass (m). In the formula, c is a constant representing the speed of light in physics. This equation is key to the development of atomic bombs. Sexual.
However, E=mc² does not clearly propose time. Its concept first appeared in 1905 “Does the inertia of an object depend on the energy it contains?” In the thesis, Einstein did not accurately describe this equation at that time, and the symbol representing energy is not E, but L.
