Who invented the formula E=mc² ?

Question

Obviously not Albert Einstein, because in his works we can not find this famous formula.
I heard a Newsweek journalist was the first to publish E=mc².
Who knows more about it?

Please excuse my bad english.
Is this better: Who derived the formula E=mc² ?

If you still think it was Albert Einstein, please show me in which part of his works I can read this equation.

Answer 1

Albert Einstein invented the formula E=mc2 (squared) but an Italian by the name of Einstein's E=MC2 'Was Italian's Idea'

The mathematical equation that ushered in the atomic age was discovered by an unknown Italian dilettante two years before Albert Einstein used it in developing the theory of relativity, it was claimed yesterday.

Olinto De Pretto, an industrialist from Vicenza, published the equation E=mc2 in a scientific magazine, Atte, in 1903, said Umberto Bartocci, a mathematical historian.

Einstein allegedly used De Pretto's insight in a major paper published in 1905, but De Pretto was never acclaimed, said Professor Bartocci of the University of Perugia.

De Pretto had stumbled on the equation, but not the theory of relativity, while speculating about ether in the life of the universe, said Prof Bartocci. It was republished in 1904 by Veneto's Royal Science Institute, but the equation's significance was not understood.

A Swiss Italian named Michele Besso alerted Einstein to the research and in 1905 Einstein published his own work, said Prof Bartocci. It took years for his breakthrough to be grasped. When the penny finally dropped, De Pretto's contribution was overlooked while Einstein went on to become the century's most famous scientist. De Pretto died in 1921.

"De Pretto did not discover relativity but there is no doubt that he was the first to use the equation. That is hugely significant. I also believe, though it's impossible to prove, that Einstein used De Pretto's research," said Prof Bartocci, who has written a book on the subject.

Einstein's theory held that time and motion are relative to the observer if the speed of light is constant and if all natural laws are the same. A footnote established the equivalence of mass and energy, according to which the energy (E) of a quantity of matter (m) is equal to the product of the mass and the square of the velocity of light (c). Now known as: E=mc2 .

The influence of work by other physicists on Einstein's theory is also controversial. A German, David Hilbert, is thought by some to have been decisive.

Edmund Robertson, professor of mathematics at St Andrew's University, said: "An awful lot of mathematics was done by people who have never been credited - Arabs in the middle ages, for example. Einstein may have got the idea from someone else, but ideas come from all sorts of places.

"De Pretto deserves credit if his contribution can be proven. Even so, it should not detract from Einstein."

RE:

Answer 3

Firstly no one INVENTS a formula...its derived. To quote from wikipedia, "The equation was first published in a slightly different formulation by Albert Einstein in 1905 in one of his famous articles. He derived it as a consequence of the special theory of relativity which he had proposed the same year." AND
"According to Umberto Bartocci (University of Perugia historian of mathematics), the equation was first published two years earlier by Olinto De Pretto, an industrialist from Vicenza, Italy, though this is not generally regarded as true or important by mainstream historians. Even if De Pretto introduced the formula, it was Einstein who connected it with the theory of relativity."

Answer 6

E = mc2 is one of the most famous equations, even to non-physicists, and which states a relationship between energy (E), in whatever form, and mass (m). In this formula, c², the square of the speed of light in vacuum, is the conversion factor required to formally convert from units of mass to units of energy, i.e. the energy per unit mass. In unit specific terms, E (joules) = M (kilograms) multiplied by (299792458 m/s) 2.

The equation was first published in a slightly different formulation by Albert Einstein in 1905 in one of his famous articles. He derived it as a consequence of the special theory of relativity which he had proposed the same year.

Answer 7

Albert Einstein was the person who derived this formula to find the relation between energy and mass of a body...
E=energy; m=mass; & c=speed of light (3.0e8)

Answer 8

Patent Clerk Albert Einstein, before he was 30.
E is the Energy produced.
M is the Mass you are converting to energy.
C is the Speed of light (very very fast) SQUARED (which yields a humongous number).

Answer 9

It was formulated by Albert Einstein in his 1905 Special Theory of Relativity. It was in Annallen der Physik, I think.... not Newsweek!

Answer 10

As stated in Family Guy, Einstein stole it from Fred, who was trying to patent his laws of relativity and other work, by bashing him on the head with a window.
