Light and all types of subatomic elementary particle show properties of both waves and particles. more...
Heisenberg Uncertainty Principle
Werner Heisenberg's uncertainty principle means that on a microscopic scale, we can know where something is or where it is going, but not both at the same time. more...
In addition to his work on relativity in 1905, Einstein published an explanation for the photoelectric effect that earned him the 1921 Nobel Prize. more...
Neutrinos are among the most elusive of elementary particles. They were not detected until about 25 years after they were first suggested to exist. more...

Principles of Particle Detection
By:
Isaac M. McPhee
The scientific explanation of what exactly is happening within a particle accelerator experiment is not that complicated. It relies on just a couple fundamental laws. more...
Linear and Circular Accelerators
By:
Isaac M. McPhee
Particle Accelerators form an enormous part of physical discovery, and as such, they are constantly getting bigger, better, and (much) more expensive. more...
Anti-Particles and Anti-Matter
By:
Isaac M. McPhee
The discovery of the positron paved the way for further realization that every particle known must also have an "anti" particle. more...
By:
Isaac M. McPhee
In the late 1920's Paul Dirac it was discovered that "normal" electrons might not be the only ones to exist. There might be an "opposite" particle as well. more...
The Quantum Totalitarian Principle
By:
Isaac M. McPhee
The Totalitarian Principle declares that anything which is not forbidden by any specific rule of physics, is required by law to occur, with no exceptions. more...
For all practical purposes, a vacuum is completely devoid of anything, it is the definition of nothingness. The reality is a bit more complicated. more...
"Parallel Universe" has been airing periodically on the Science Channel, and is one of the most comprehensible introductions to the topic. more...
