The mass and energy were in fact equivalent, according to the formula mentioned before. Furthermore, the equation E = mc², in which energy is put equal to mass, multiplied by the square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa. In a later statement explaining the ideas expressed by this equation, Einstein summarized: "It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing - a somewhat unfamiliar conception for the average mind.The equivalence of mass and energy was originally expressed by the equation m = L/c², which easily translates into the far more well-known E = mc² in Does the Inertia of a Body Depend Upon Its Energy Content? published in the Annalen der Physik (27 September 1905) : "If a body gives off the energy L in the form of radiation, its mass diminishes by L/c².".Opening of a letter to his friend Conrad Habicht in which he describes his four revolutionary Annus Mirabilis papers (18 or ) Doc.What are you up to, you frozen whale, you smoked, dried, canned piece of soul.? Dear Habicht, / Such a solemn air of silence has descended between us that I almost feel as if I am committing a sacrilege when I break it now with some inconsequential babble.Was machen Sie denn, Sie eingefrorener Walfisch, Sie getrocknetes, eingebüchstes Stück Seele.? Lieber Habicht! / Es herrscht ein weihevolles Stillschweigen zwischen uns, so daß es mir fast wie eine sündige Entweihung vorkommt, wenn ich es jetzt durch ein wenig bedeutsames Gepappel unterbreche.Einstein had been annoyed that Paul Drude, editor of Annalen der Physik, had dismissed some criticisms Einstein made of Drude's electron theory of metals.

Einstein is known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Blind obedience to authority is the greatest enemy of truth.Īlbert Einstein ( 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest physicists of all time. Most people are even incapable of forming such opinions. Few people are capable of expressing with equanimity opinions that differ from the prejudices of their social environment. But the ends themselves are conceived by personalities with lofty ethical ideals and - if these ends are not stillborn, but vital and vigorous - are adopted and carried forward by those many human beings who, half unconsciously, determine the slow evolution of society. Science, however, cannot create ends and, even less, instill them in human beings science, at most, can supply the means by which to attain certain ends. Socialism is directed towards a social-ethical end. A hundred times every day I remind myself that my inner and outer life are based on the labors of other men, living and dead, and that I must exert myself in order to give in the same measure as I have received and am still receiving.
