In this video Paul Andersen explains how mass can be converted to energy and energy can be converted to mass. The equation E=mc2 can be used to determine the amount of energy released from nuclear processes.

Everyone and their mom knows about E = mc^2, it's the most famous equation in science, and there are plenty of posters you can buy for your dorm room with Einstein's face and this equation floating mysteriously around his head. But what...

Nuclear Fission In a nuclear reactor the controlled slow release of energy is used to heat up a closed loop of coolant which passes to heat exchangers which then boil water to provide steam to turn electrical generators. The output of...

Hydrogen bomb how does it work? The bomb on Hiroshima released the energy equivalent of 15,000 tons of TNT. The first hydrogen bomb released the energy equivalent of 10,000,000 tons of TNT.



While...

QCD: Quantum Chromodynamics. How can positive protons be so close together in the nucleus, if they repel each other? Japanese physicist and Nobel laureate Hideki Yukawa sought to answer this question. He proposed...

This video is about how efficient various reactions are at converting mass to energy (as we know from the Einstein mass-energy equivalence of E=mc^2). Antimatter is very efficient but it is not...

Certain mathematical equations contain unnerving dangers, Arguably, E=mc^2 is the most famous equation in science. C is a very large number. But in Einstein’s, equation it is squared. This means that mass contains an insane...

In this video about Albert Einstein for Kids we learn about one of the most famous scientists in history. Albert Einstein contributed to many scientific areas but one of his most important contribution to the world of physics and science...

What is string theory? When string theory is simplified - it can answer the question "Why do we exist?" First you must accept that there are two worlds we live in - the world of the large, the world we can see, which...

What is the purpose of light? How does light work? Why does Light exist? There had been a controversy about whether light was particles or waves. Albert Einstein showed that light must come in discrete packets of...

How the Planck scale is derived from the most important fundamental constants in physics. This is where our physics ends. If you wanted to simulate the universe in a computer, you would need to enter...

Is a theory of everything really possible? What makes us think it even exists? If we look at historical precedent, we can see that we have united seemingly completely unrelated forces and particles to a...
