Best Fundamental physics Videos
The 164 Fundamental physics videos here were recommended by different people across different months. Choose by who it is for: 12 introductory, 23 intermediate, 122 for a general viewer, and 7 for someone who wants the harder derivation. Most of them are an explainer. What they share is that one picture or analogy is used to supply a missing concept. Channels you will keep seeing include Veritasium, PBS Space Time, Christopher Sykes.

The Most Misunderstood Concept in Physics
Veritasium's explainer on entropy, presented as one of physics' most important and least understood concepts.

How Time Becomes Space Inside a Black Hole | Space Time
A PBS Space Time episode explaining how space and time swap roles inside a black hole's event horizon.

A New Way to Achieve Nuclear Fusion: Helion
Real Engineering's Brian McManus explains Helion's approach to nuclear fusion: colliding two plasma rings, compressing them magnetically, and capturing energy directly from the changing magnetic flux rather than boiling water.

Stephen Wolfram: Cellular Automata, Computation, and Physics | Lex Fridman Podcast #89
Lex Fridman interviews Stephen Wolfram for about three hours on cellular automata, computation, the Wolfram Physics Project and his career with Mathematica and Wolfram Alpha.

How to Understand What Black Holes Look Like
Veritasium explains what a black hole should look like, using J.P.

Geoffrey West on COMPLEXITY
Physicist Geoffrey West speaks at an FQXi conference on time about complexity and scaling laws.

How We're Redefining the kg
Veritasium explains why the kilogram is being redefined in terms of Planck's constant rather than a physical metal artifact.

A Portal Special Presentation- Geometric Unity: A First Look
Eric Weinstein's roughly three-hour presentation of Geometric Unity, his proposed theory unifying physics, given as a special episode of The Portal.

The True Nature of Matter and Mass | Space Time | PBS Digital Studios
A PBS Space Time episode asking what matter, mass, and energy really are, starting with inertial versus gravitational mass and what mass-energy equivalence means.

Richard Feynman Lecture -- "Los Alamos From Below"
A 78-minute Richard Feynman lecture of anecdotes about working at Los Alamos on the Manhattan Project, followed by about ten minutes of audience Q&A in which he tells three safe-cracking stories.

Stephen Wolfram: Complexity and the Fabric of Reality | Lex Fridman Podcast #234
A long Lex Fridman interview with Stephen Wolfram on complexity, cellular automata, computational irreducibility and the Wolfram Physics Project.

Connections between physics and deep learning
Max Tegmark's MIT CBMM talk on why deep learning works so well.

Is The Alcubierre Warp Drive Possible? | Space Time | PBS Digital Studios
PBS Space Time introduces Miguel Alcubierre's warp drive, explaining how spacetime itself could be warped rather than moving a ship through it, and whether it is physically possible.

How are holograms possible?
3Blue1Brown explains how holograms record a 3D scene on 2D film, using wave diffraction and phase.

How the Higgs Mechanism Give Things Mass
A PBS Space Time episode on how the Higgs mechanism gives particles mass, prompted by Fermilab's heavier-than-expected W boson measurement.

Richard Feynman Magnets
A short clip of Richard Feynman answering an interviewer's question about how magnets work, in which he explains why a why-question has no simple answer without a shared frame of reference.

Doug McLean | Common Misconceptions in Aerodynamics
Retired Boeing Technical Fellow Doug McLean walks through common misconceptions in aerodynamics, drawing on his book Understanding Aerodynamics.

the sham legacy of Richard Feynman
Physicist Angela Collier's nearly three-hour critique of Richard Feynman's public legacy.

Cosmos - Carl Sagan - 4th Dimension
A segment from Carl Sagan's original Cosmos explaining the fourth spatial dimension through analogy with a two-dimensional world and shadow projection.

Are Space and Time An Illusion?
A PBS Space Time episode hosted by Gabe Perez-Giz on the nature of spacetime and whether space and time are fundamental.

The Biggest Misconception in Physics
Veritasium explores why energy is not conserved in general relativity, using Emmy Noether's theorem linking symmetries to conservation laws.

What Happens at the Event Horizon? | Space Time | PBS Digital Studios
PBS Space Time explains what happens as you approach and cross a black hole's event horizon, using Penrose diagrams and light cones as the tool for understanding spacetime there.

Feynman: Mirrors FUN TO IMAGINE 6
Richard Feynman, in a clip from the BBC series Fun to Imagine, takes on the puzzle of why mirrors seem to swap left and right but not top and bottom.

How Electricity Actually Works
Veritasium explores how electrical energy actually travels in a circuit, arguing that it flows through electromagnetic fields around the wires rather than through the electrons.
