The standard model describes four fundamental forces; gravitational, electromagnetic, strong and weak. How is gravity different? [Read more…] about How does gravity compare to the other fundamental forces?
Quantum and Particle Physics
There are four fundamental forces of nature: gravitational, electromagnetic, strong and weak. Each force can be explained using fields and 3 also have bosons associated with them, known as force carriers. [Read more…] about Fundamental Forces
Feynman diagrams are used to graphically show particle interactions in a simple way. There are some basic rules which can be followed in order to learn how they are drawn. [Read more…] about Feynman Diagrams
Wave particle duality is the idea that all particles can be described as waves as well as particles. Experiments with light showing it acting as a wave and particle have helped us to understand and develop this theory. [Read more…] about Wave-Particle Duality
It is a widely accepted fact in physics that the speed of light is the fastest any particles can travel. In 2011, neutrinos appeared to have been found going faster than the speed of light. Although this was later disproved, some physicists believe faster-than-light particles are possible. [Read more…] about Is it possible to go faster than the speed of light?
The standard model was developed in the 1970s and it classifies all of the known elementary particles, of which there are 17. Twelve of these are matter particles, grouped as quarks and leptons. Another four make up the charge carriers group, one for each of the fundamental forces. The final elementary particle and the latest addition to the standard model is the Higg’s Boson.
