In Albert Einstein's famous equation E=mcˆ2 (read E equals M C squared) the "c" is the speed of light and "m" is the mass of an object and E is the amount of potential energy.
One use of this formula is to calculate how much energy an object could release if it could be entirely converted to energy. This is almost impossible but the reaction in an H-bomb is a good example.
Assuming you could convert a 1 kilogram rock entirely into energy, how much energy would be released?
This is a relatively simple problem. Using Einstein's formula...
E = 1 kg x (300,000,000 m/s)ˆ2
Using your scientific calculator (or you can just trust us) that is 90,000,000,000,000,000 joules.
This is roughly enough energy to power all cars in the US for a week!
Note: to make things easy we are ignoring all the units in our calculations. However, if weight is in kg and speed of light in m/s the answer will be in a unit of energy called a "joule".
2.How Nuclear Bombs Work
But the events in Japan, although they brought a close to World War II, marked the beginning of the Cold War between the United States and the Soviet Union. Between 1945 and the late 1980s, both sides invested huge amounts of money in nuclear weapons and increased their stockpiles significantly, mostly as a means to deter conflict. The threat of catastrophic destruction from The Bomb loomed over everyone and everything. Schools conducted nuclear air raid drills. Governments built fallout shelters. Homeowners dug bunkers in their backyards.
During the 1970s and '80s, tensions began to ease somewhat. Then the Berlin Wall fell in 1989, followed by the collapse of the Soviet government itself two years later. The Cold War officially ended. As relations between the two countries improved, a commitment to limit nuclear arsenals emerged. A series of treaties followed, with the latest going into effect in February 2011. Like its predecessors, the new Strategic Arms Reduction Treaty (START) aims to further reduce and limit strategic arms. Among other measures, it calls for an aggregate limit of 1,550 warheads [source: the White House].
Unfortunately, even as Russia and the U.S. step tentatively away from the brink, the threat of nuclear warfare remains. Nine countries can now deliver nuclear warheads on ballistic missiles [source: Fischetti]. At least three of those countries -- the U.S., Russia and China -- could strike any target anywhere in the world. Today's weapons could easily rival the destructive power of the bombs dropped on Japan. In 2009, North Korea successfully tested a nuclear weapon as powerful as the atomic bomb that destroyed Hiroshima. The underground explosion was so significant that it created an earthquake with a magnitude of 4.5 [source: McCurry].
While the political landscape of nuclear warfare has changed considerably over the years, the science of the weapon itself -- the atomic processes that unleash all of that fury -- have been known since Einstein. This article will review how nuclear bombs work, including how they're built and deployed. Up first is a quick review of atomic structure and radioactivity. Refrence
3.What is E Mc2?
The formula E=Mc2 is the formula used to find the energy output of an object. Energy equals mass times velocity squared. The mass of the object times the velocity it is moving which is multiplied
4.How did Albert Einstein contribute to math?
From an early age Albert Einstein was extremely clever in all things mathematical. Before he was 15 he had an excellent grasp of even such matters as calculus (a form of mathematics that uses symbols to represent change and limits to change).
In due course he developed the practice of imagining physical events, and then he devised ways of expressing those ideas using calculus. His theory of relativity uses the symbols and methodology of differential calculus, thereby showing that the complexities and wonders of light, gravity, time and the universe can be expressed in mathematical terms.
Einstein's works regarding the mathematics of the physics of gravity, and the relationships between matter, momentum and time, still stand as a testimony to the value of mathematics in being able to portray and explain complex physical realities.
For example, his theory of relativity and his mathematical formula E=mc2 show how energy and mass have a direct and equivalent relationship with each other, i.e. that mass can be converted into energy, and that the resulting energy would be directly and mathematically proportionate to the total mass.
Taking Einstein's work a stage further, he showed how mathematics can be used in a predictive way, with a very high degree of accuracy. His works are fundamental to space science and our understanding of the movements of planets, stars and galaxies over time.
Development of the mathematics of Einstein's general theory of relativity led scientists to predict the existence of black holes in outer space, which subsequent analysis of space research data seems to confirm.
The fact that Einstein's mathematical theories have been invaluable in expanding the field of space research has moved many scientists to continue in mathematics where Einstein left off, and that enthusiasm for mathematics, i.e. for what they can do and how they can be improved, has motivated and inspired many students and scientists to continue in their endeavours to discover and express in mathematical terms the fundamental truth's about matter, life, the universe and everything.
