Nuclear science is the study of sub-atomic particles and their application in various disciplines. Here you can learn about nuclear power plants, atomic theory and radiation.
Iran has announced its activation of a second set of uranium centrifuges. These machines are at the core of the uranium-enrichment process. Find out where the centrifuge fits into the equation. See more »
Infrared Radiation, electromagnetic radiation with wavelengths between those of visible red light and radio waves.
See more »Irradiation, exposure to radiation, such as X rays or ultraviolet rays, usually for a specific purpose.
See more »Isotope, in chemistry, one of two or more forms of an element that have the same atomic number but different atomic weights.
See more »Neutrino, an elementary particle that has no electric charge. Physicists believe that neutrinos have either an extremely small mass or no mass at all.
See more »Nuclear Energy, energy released in large amounts by the splitting or formation of atomic nuclei.
See more »Nuclear Physics, the branch of physics that deals with the atomic nucleus, or inner core of the atom.
See more »Particle Accelerator, a device that accelerates electrons, protons, or other charged particles to very high speeds.
See more »Quantum Theory, the theory that radiant energy is emitted (given off) and absorbed in units, or quanta, rather than in a steady stream.
See more »Quark, a particle that physicists believe is a basic constituent of protons, neutrons, and certain other subatomic particles collectively known as hadrons.
See more »Radiation, the emission and transmission of energy and particles of matter from atoms.
See more »Radioactivity, the process by which the nuclei (cores) of unstable atoms of an element emit radiation (particles of matter and rays of energy), and in so doing become atoms of other elements.
See more »Many ads for new clocks advertise their ability to automatically synchronize themselves with the atomic clock in Boulder, Colorado. This atomic clock is more precise because it uses the frequencies of atoms as its resonator.

One side of the diamond was black and the other was white. I did a little research and found out that it was called a Crookes' radiometer -- how does it work?
