MinutePhysics

Season 2021

In MinutePhysics Henry Reich provides concise, easy to understand explanations of physics principles in every day language in about a minute. And to make the physics easier to understand he hand sketches diagrams so you can also see what he's talking about. Topics tend to previews or introductions to more in depth programs available through various online services.

Where to Watch Season 2021

9 Episodes

  • The Case for LESS Sensitive COVID Tests
    E1
    The Case for LESS Sensitive COVID TestsThis video is about how cheap, fast, and LESS sensitive rapid antigen tests might be better for screening (& maybe surveillance) than PCR COVID tests due to the nature of contagiousness/infectiveness at various points on the viral load trajectory of symptomatic and asymptomatic COVID sars-COV-2 carriers.
  • General Relativity Explained in 7 Levels of Difficulty
    E2
    General Relativity Explained in 7 Levels of Difficulty
  • The Physics of Windmill Design
    E3
    The Physics of Windmill DesignThis video is about how physics dictates the design of modern windmills - why they are so big, have so few blades, and have such skinny blades.
  • Why Do Boats Make THIS Pattern?
    E4
    Why Do Boats Make THIS Pattern?This video is about the "Kelvin wake" shape of water wakes behind boats - we talk about mach angle, dispersion, superposition of many waves, and how these all lead to the pattern of a wake. We don't get into Froude number though...
  • Solution to the Windmill Paradox
    E5
    Solution to the Windmill ParadoxThe Solution to the Windmill Paradox. This video is about the tradeoff of Windmills: the fact that the more kinetic energy you extract from the wind the slower the wind goes, the less wind you have to extract energy from, etc. How much energy is the sweet spot to extract from the wind??
  • A Better Way To Picture Atoms
    E6
    A Better Way To Picture AtomsThis video is about using Bohmian trajectories to visualize the wavefunctions of hydrogen orbitals, rendered in 3D using custom python code in Blender.
  • The Rocket & String Paradox
    E7
    The Rocket & String ParadoxThis video is about Bell's Spaceship Paradox of Special Relativity, wherein a pair of rockets (or spacecraft) connected by a weak thread accelerate with uniform acceleration, maintaining the same separation, and the question is: does the thread break? And if so, why?
  • The Problem With The Butterfly Effect
    E8
    The Problem With The Butterfly Effect
  • Is Anything on the Internet Real?
