Cosmic Rays
Cosmic ray is the term given to high energy radiation which strikes the Earth from space. Some of them have ultrahigh energies in the range 100 - 1000 TeV. Such extreme energies come from only a few ...
Energy Efficiency and Renewable Energy
A US government site which considers the efficient use of energy today and the alternative renewable energies which will supply our energy in the future.
Enthalpy
A short summary of this thermodynamics topic including internal energy, Helmholtz and Gibbs free energies.
Bohr Model
Combining the energy of the classical electron orbit with the quantization of angular momentum, the Bohr approach yields expressions for the electron orbit radii and energies.
Relativistic Energy
The famous Einstein relationship for energy includes both the kinetic energy and rest mass energy for a particle.
Conservation Of Energy
One way to describe the Conservation of Energy is "Energy can neither be created nor destroyed". Another approach is to say that the total energy of an isolated system remains constant.
Elastic Photon-Atom Scattering
Allows relativistic Hartree-Fock-Slater anomalous scattering factors and differential cross sections to be calculated for various energies , angles and materials
Energy Matters
A series of articles on Kinetic Energy, Potential Energy, Relativity, Work, Fossil Fuels, Nuclear, Hydroelectric, Biomass, Wind and Geothermal power. The site uses text and colour illustrations and ...
Chemicool Periodic Table
An easy to follow periodic table of the elements. Includes a variety of information on each element including states, energies etc.
Energy in Electromagnetic Waves
Electromagnetic waves carry energy as they travel through empty space. There is an energy density associated with both the electric and magnetic fields. The rate of energy transport per unit area is ...
