Introduction to Relativity
Relativity is a cornerstone of modern physics developed by Albert Einstein. It helps us understand how space and time are intertwined and how they affect the objects within them. You can imagine it like a stretchy fabric, bending and curving under the influence of mass and energy. Fun fact: GPS technology uses relativity to provide accurate location information by accounting for time dilations due to gravity!
E=mc²: The Equation That Changed the World
This iconic equation demonstrates the equivalence of mass and energy. In this profound relationship, a small amount of mass can be converted into a significant amount of energy, exemplified by the power of the sun and the workings of nuclear reactors on Earth.
