The (Arguably) Most Important Instrument in Physics
Thermometers might seem like a basic instrument, but science would not be the same without them, and they helped us understand one of the most important ideas in all of science: the conservation of energy.

Energy-Mass Equivalence
In this video Paul Andersen explains how the law of conservation of energy applies to both energy and mass. Einstein showed that mass and energy are equivalent and that the amount of energy contained within matter can be calculated...

The Law of Conservation: Crash Course Engineering #7
Today Shini explains the law of conservation, beginning with simple, steady-state systems. We’ll discuss conversion and yield, accumulation, and how generation and consumption can affect how much accumulation there is in a system.

What is the Law of Conservation of Energy?
The law of conservation of energy tells us that energy is neither created or destroyed - just converted from one form to another. This means that we cannot make energy from nothing and energy does not just disappear. Energy, however, can...
