What the terms systems and surroundings mean in chemistry
By: Brandon Sharp
The scientific discipline of chemistry includes a branch called thermodynamics that observes the changes that take place with different forms of energy. In this branch, the concepts of system and surroundings are used repeatedly. A system, in thermodynamics, is simply something a scientist is interested...
Breakthrough: Laser light transforms material into a superconductor
By: Terrence Aym
For decades researchers have been searching for a way to achieve superconductivity other than bringing special materials down to a temperature near absolute zero.Now Oxford University researchers report non-superconducting material can be made a superconductor by using laser light. Professor Andrea Cavalleri of the...

Most areas of physics are pretty much open to wild and woolly exploration. A few areas that aren't include perpetual motion machines that violate the Laws of Thermodynamics, specious claims of achieving room-temperature superconductivity and the touchy subject of cold fusion nuclear reaction.Cold fusion...

There is a scientific law called electromagnetic induction, which basically states that an electric current is manufactured when any sort of electric conductor moves through a magnetic field. On the basis of this law, all sorts of generators have been built. Examples of different generators...
