TED-Ed: What is the Heisenberg Uncertainty Principle?

The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Why not? Because everything in the universe behaves like both a particle and a wave at the same time. Chad Orzel navigates this complex concept of quantum physics.

Lisa Randall: Expanding Our Horizons | Matter, Space, and the Universe

This session explores the almost unfathomable scales of theoretical physics, from the mysterious properties of dark matter to the depths of our universe and beyond. Experiments, like the Large Hadron Collider near Geneva that smashes together protons at high energies, tell us about the smallest length scales we can observe today while measurements of the …

AMNH: 2011 Isaac Asimov Memorial Debate: The Theory of Everything

Can the entire universe be explained with a single, unifying theory? This is perhaps the most fundamental question in all of science, and it may also be the most controversial. Albert Einstein was among the first to envision a unified theory that could account for the behavior of all matter and energy in the cosmos, …
