How To Make MUONS
This video is about how to create muons in a particle accelerator via bombardment of heavy nuclei with protons, which results in creation of charged pions (plus and minus). The pions then decay into muons and mu neutrinos, and the muons...

How We Know Black Holes Exist
Thanks to the James Webb Space Telescope (JWST) and Space Telescope Science Institute for supporting this video. This video is about the astronomical amount of astronomical evidence for black holes, ranging from x-ray binaries with...

Legitimate Cold Fusion Exists | Muon-Catalyzed Fusion
This video is about the original cold fusion: μ muon-catalyzed cold fusion of deuterium, tritium, hydrogen, into helium-3 and helium 4. The problems with it are the half-life of muons and the sticking of muons to alpha particles. Also...

Solar Panels Made With a Particle Accelerator?!
This video is about using particle accelerators as part of the solar panel silicon wafer manufacturing process. The accelerators embed protons into the wafer crystals, allowing them to break and separate from the main crystal in much...

How Quantum Computers Break Encryption | Shor's Algorithm Explained
This video explains Shor’s Algorithm, a way to efficiently factor large pseudoprime integers into their prime factors using a quantum computer. The quantum computation relies on the number-theoretic analysis of the factoring problem via...

Complete Solution To The Twins Paradox
This video is about the famous 'Twins paradox' of special relativity, how time can appear to be faster for two different observers at the same time, and which twin really is older (or younger) - the one who stays on earth or the one who...

Do Photons Cast Shadows?
This video is about two-photon (gamma-gamma) physics, and how photons can interact with each other - either mediated by a passing lepton, or gravitationally via lensing, or via vacuum fluctuation pair production of vertical particles...

Why It's HARD To Land on Mars
This video is about why it's harder to successfully land spacecraft and landers and rovers on Mars than on Earth, or Venus, or the Moon, or Titan, or asteroids. It all comes down to atmospheric density! When there's no atmosphere, you...

How ISPs Violate the Laws of Mathematics
This joke video is about how Internet Service Providers (aka ISPs, internet companies, telecommunications companies, etc) violate the basic axioms of Zermelo-Fraenkel set theory. Like the axiom of choice (sometimes Well-ordering...

The Portal Paradox
This video is about the Portal Paradox - a paradox in the video game Portal (and Portal 2) regarding whether or not a companion cube passing through a moving portal plops out of the other end with no speed (velocity, momentum), or shoots...
