EINSTEIN PRESENTATION

After the Second World War, Einstein tried in every way to promote peace in the world, promoting a vast popular campaign against war and racist persecution. Just a week before his disappearance, together with seven other Nobel laureates, he compiled a pacifist declaration against nuclear weapons together with Bertrand Russell.

We appeal as human beings to human beings: remember your humanity and forget the rest. If you are able to do so, the way to a new paradise is open, otherwise the risk of universal death lies ahead of you.

The most famous and well-known physicist in the world, died April 17, 1955, Princeton, New Jersey, United States. He was cremated and his ashes were scattered in an unknown place

Einstein, a staunch pacifist, regretted signing the letter addressed to roosevelt, and as he himself said

"I made one great mistake in my life, when I signed a letter to President Roosevelt recommending that atom bombs be made."

A CITIZEN OF THE WORLD

Albert Einstein was born at Ulm in Germany on March 14, 1879. He lived in Switzerland, Italy and USA ( Princeton) from 1933 onwards. He always considered himself a citizen of the world.

In 1933, when Adolf Hitler was elected chancellor, the rift between Germany and Einstein widened, and the physicist was immediately persuaded to renounce his German citizenship. the physicist, born to a Jewish family, resigned and moved to the United States. Meanwhile the Nazis broke into his apartment burning all his writings and theories on relativity

THE LETTER

Einstein agreed, after meeting with the physicists Szilard and Wigner, to sign a public document to urge the creation of a nuclear device before it is built by Hitler. On August 2, Einstein signs the letter addressed to President Roosevelt

THE END

Roosevelt proposed to Einstein to join the committee but he declined in a letter dated April 25, 1940. This marks the end of any relationship he had with the activities that led to the American atomic bomb.

Fear of the Nazi threat had transformed Einstein's political outlook

a few moments earlier

In December 1938 in Berlin, the chemists Hahn and Strassman had obtained the nuclear fission of uranium and had given a physical interpretation of it. The Danish physicist Niels Bohr was first informed, who in January 1939, during the fifth theoretical physics conference in Washington, spread the news. Fermi, present at the conference and considered the greatest expert in nuclear physics, hypothesized that it would give rise to a nuclear chain reaction of unprecedented power

THE BIG MISTAKE

Faced with the threat posed by the Nazi regime, Einstein renounced his pacifist positions and in 1939, together with many other physicists, wrote a famous letter addressed to President Roosvelt in which the possibility of creating an atomic bomb was underlined

E = mc^2 is the formula that establishes the relationship between energy and mass of a physical system

Einstein's equation allows you to determine how much energy was released by the radioactive decay of a uranium nucleus

Mass-energy conversion was crucial in the development of the atomic bomb

the annus mirabilis papers

Are the four papers that Albert Einstein published in Annalen der Physik, a scientific journal, in 1905. These four papers were major contributions to the foundation of modern physics.

the NOBEL PRIZE IN PHYSICS

It was awarded to Albert Einstein "for his services to Theoretical Physics, and especially for his discovery of the law of photoelectric effect"

The physicist received notification of the victory while he was traveling to Japan, so he could not take part in the traditional award ceremony in Stockholm. He only received it in July 1923 in Gothenburg.
