NOTHING CAN GO FASTER THAN LIGHTOf course the idea that there is an ultimate speed limit seems absurd. While the speed of light is very high by earthly standards, the magnitude is not the point; any k...
It may seem strange that the same term that slows the spatial evolution of a field also causes it to oscillate, but it is actually straightforward mathematics to show that the frequency of oscillation...
In QFT, the various fields, even the matter field, appear separately, each with its own equation and its own behavior. They are not combined into a single field as Einstein hoped, but they are related...
General spin is an abstract mathematical concept that is related to the number of field components and how they change when viewed from different angles. The more field components, the higher the
The job of science is to look beyond our intuition, to find out by any means possible what's really going on, and to give up old ways of thinking when the evidence requires it.
Schrodinger, despite some misgivings, believed that the electron is a real wave spread throughout all of space
Energy. In classical physics, energy means the ability to do work, which is defined as exerting a force over a distance. This definition, however, doesn't provide much of a picture, so in classical ph...
The number of matter quanta in a given region or state is limited by the Exclusion Principle.
