The Basics
The Basics What do the E = mc2 units mean? Solving the Equation A simple walk-through of the equation  Deriving the Equation 1 Deriving E = mc2 without calculus  Deriving the Equation 2 Deriving E = mc2 using calculus (advanced) Energy from Radioactive Decay What is radioactive decay?  Energy from Nuclear Fission Pulling atoms apart  Energy from Nuclear Fusion Squeezing atoms together
E = mc2 Explained
The purpose of these pages is to explain E = mc2 in a clear, concise and understandable way with easily followed worked examples, and with further pages examining the special theory of relativity in order to describe its background. Albert Einstein published his Special Theory of Relativity in 1905 and in doing so discovered that mass and energy are actually the same thing, with one a tightly compressed manifestation of the other. This mass-energy equivalence has had a major impact on all our lives, although how and why isn't always obvious. Although relativity has a reputation for being difficult much of it can be understood by anyone. *** Gravity waves detected February 2016 -- See In the News ***
