EINSTEIN’S WORLD____E=mc2

The greatest scientist in 20 century.

制作,宣讲 许珊


E mc 2

E=mc2

At age 26, Einstein discovered between energy and mass is expressed in the equation E=mc² . Here E represents energy,m represents mass, and c² is a number, the square of the speed of light.

This photograph not only shows the conversion of energy to mass, but confirms Einstein's idea that a light-particle will yield up its quantum of energy all at once in a single burst.


The voice of einstein

THE VOICE OF EINSTEIN

"It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing -- a somewhat unfamilar conception for the average mind. Furthermore, the equation E is equal to m c-squared, 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. The mass and energy were in fact equivalent, according to the formula mentioned before. This was demonstrated by Cockcroft and Walton in 1932, experimentally."


The end

THE END

"In light of knowledge attained, the happy achievement seems almost a matter of course, and any intelligent student can grasp it without too much trouble. But the years of anxious searching in the dark, with their intense longing, their alterations of confidence and exhaustion and the final emergence into the light -- only those who have experienced it can understand it."
