The Standard Model (of Particle Physics) Explained
We explain the standard model of particle physics in simple terms for non-experts using videos, facts, and bullet points.
Physical Sciences
The Physical Sciences are branches of science that study non-living systems including Astronomy, Chemistry, Earth Science, and Physics.
Glass Can Be a Liquid
Glass, in any form, is not a liquid or a supercooled liquid, and it does not “flow” in its solid state. Glass is considered an amorphous solid, or just “glass.”
Fluoride is Bad For You
Fluoride is a name for several fluorine compounds. Fluoride is good for oral hygiene in small doses, but extremely dangerous and toxic in large doses.
Hot Water Can Freeze Faster than Cold Water
Hot water can freeze faster than cold water, but it does not always do so. This “Mpemba effect” may be related to “supercooling”, but that hasn’t been proven yet.
Astrology is Based on Science
Aspects of astrology are rooted in the science of astronomy and the academic tradition, but today astrology is considered a pseudoscience.
There is a “Plastic Garbage Island” in the Ocean
There is no visible “plastic island,” or “garbage patch” in the ocean. Instead, large low-density patches of plastic particles are caught in the ocean’s major gyres below the water’s surface.
Light is Both a Particle and a Wave
Light is a particle (a photon), that acts like a wave (“both a particle and a wave”), which can be measured as an excited quantized state of the electromagnetic field.
A Planck Unit Represents the Smallest Measurable Unit
Planck units, based on the reduced Planck constant (ℏ) and Planck constant (h), represent the smallest measurable units in the physical universe.
All Particles are Made from Massless Particles
All known particles are either massless energy particles, or are composite particles with mass that are made from massless energy particles.
Einstein Wrote ‘E=mc^2’ in His Famous Paper
Einstein’s 1905 paper on mass-energy equivalence doesn’t actually say ‘E=mc^2‘ it says, roughly, ‘m=L/c^2‘.
