Physics Experiments: Center of mass lower than buoyancy center
Simon was trying to get a cylindrical beaker to float in water (first in bath and then in a deeper bowl), by filling it with the optimal number of marbles. … Continue reading Physics Experiments: Center of mass lower than buoyancy center
Electromagnetic Spectrum and the Opponent-process Theory
Simon has been fascinated about theĀ Opponent-process theory (suggesting that color perception is controlled by the activity of three opponent systems, three independent receptor types which all have opposing pairs: white … Continue reading Electromagnetic Spectrum and the Opponent-process Theory
Illumination Problem
Simon studying light reflection as part of the so-called Penrose Illumination Problem: if a room with mirrored walls can always be illuminated by a single point light source, allowing for … Continue reading Illumination Problem
Newtonian GPS would place you on the wrong planet!
Simon explains why our modern satellite navigation (the Global Positioning System or GPS) is a great experimental proof for Einstein’s relativity theory and what would happen if the software calculated … Continue reading Newtonian GPS would place you on the wrong planet!
Physics Experiments: Will the wooden block fall?
This is almost a magic trick that Simon borrowed from the Actionlab channel. Will the wooden block fall down on the ground once you let it go? Obviously, it will. … Continue reading Physics Experiments: Will the wooden block fall?
Physics Experiments: No Spill?
Simon trying to build a device that allows to carry a cup without spilling the liquid, i.e. with a minimum lateral acceleration to the cup. Extra footage of us having … Continue reading Physics Experiments: No Spill?
Geomag Gravity Engine
Simon is very interested in gravity engines, especially since he learned that such engines are being used in real life as safe alternatives in remote areas with no power supply … Continue reading Geomag Gravity Engine
About Maxwell
Simon: You can derive the speed of light from Maxwell’s equations. Me: Because they used to think it was infinite, right? Simon: Maxwell’s equations aren’t invariant to the Galilean transformation, … Continue reading About Maxwell
More quantum physics: quarks hit by photons and what does a z boson do?
Simon told me about strong force and what happens to a quark inside a nucleon if a high energy photon hits it and pushes it outside the nucleon: a new … Continue reading More quantum physics: quarks hit by photons and what does a z boson do?
