 Science in my out most opinion, is a very hard subject if you don't know what your doing. Science from Greek is known as "Knowledge" and Science has very high classifications upon departments and subjects. And the very complexity makes it very hard, with memorization of big words, and into the mathematical computations of Physics with displacement. With the scientific method, to expirements, to essays, and lectures, or projects, so many things that you have to do in Science as "Homework" or something stuck word of "adenosine triphosphate"
 
I know upon:

-Biology
-Astronomy
-Computer Science
-Geography
-Parts of Chemistry
-Most of Physics
-Political Science
-Earth Science
-Archaeology
-Demography

My experience in science was undeterred in my childhood, and I think by starting with this as my most strong academic points. One of my experinces was when I was in grade six I "taught" a class of 8th graders on their planets, and physics. And last year, teaching more physics to 4th year, or equivalent to 10th grade. So please ask away, but don't expect me to know it, because I'm still a learning child.

Let's start with this then, please explain E=MC squared, I want to know...

E=MC2 is one of Einstein's equation, that is very much upon how the universe is.

E is for energy = to the Multiplication of Mass and C as The speed of light squared, so in essense there can not be any more energy than that is contained in it's mass. For example, the Atom Bomb, was with these uranium, and then subjected with a uranium bullet, this caused a chain reaction that in it's mass of uranium with the reaction accruing, of splitted atoms, in a course of a few seconds... will make energy enough to burst. The same is done in a star with nuclear fusion. And vice versa, for energy itself to turn into a mass.

The Manhatten Project, did in fact produce the first tangible evidence of E=MC2...the atomic bomb!

One of Einstein's great insights was to realize that matter and energy are really different forms of the same thing. Matter can be turned into energy, and energy into matter.
For example, consider a simple hydrogen atom, basically composed of a single proton. This subatomic particle has a mass of
0.000 000 000 000 000 000 000 000 001 672 kg
This is a tiny mass indeed. But in everyday quantities of matter there are a lot of atoms! For instance, in one kilogram of pure water, the mass of hydrogen atoms amounts to just slightly more than 111 grams, or 0.111 kg.
Einstein's formula tells us the amount of energy this mass would be equivalent to, if it were all suddenly turned into energy. It says that to find the energy, you multiply the mass by the square of the speed of light, this number being 300,000,000 meters per second (a very large number):

= 0.111 x 300,000,000 x 300,000,000
= 10,000,000,000,000,000 Joules
This is an incredible amount of energy! A Joule is not a large unit of energy ... one Joule is about the energy released when you drop a textbook to the floor. But the amount of energy in 30 grams of hydrogen atoms is equivalent to burning hundreds of thousands of gallons of gasoline!

 Ah yes... MsRR, it is Indeed the very manipulation of Einstein's equation into warfare. The thing is, when they triggered a uranium bullet into a uranium tank, and when atom smashed into atom it made an energy, which then hit other particles with another causing more release of energy, and put together, a big intense mechanism of war was created.

Albert Einstein was able to see where an understanding of this formula would lead. Although peaceful by nature and politics, he helped write a letter to the President of the United States, urging him to fund research into the development of an atomic bomb ... before the Nazis or Japan developed their own first. The result was the Manhattan Project.  It was no manipulation..
