The word physics is ultimately derived from the Ancient Greek, phusika, 'natural things' from the root phusis 'nature'. It is the branch of science concerned with the properties and nature of matter and energy, the two things from which our world, our universe and we...

A group of walkers come across a cave and they saw something walk inside. Intrigued they approached the opening of the cave and one walker yelled, “HELLO?” and to their surprise, all they heard was a distorted return of the walker’s voice...
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...

Rolf Mueller, an assistant professor of mechanical engineering at Virginia Tech, thinks the geometry of bat ears may prove useful for self-contained, robotic flight systems.When many people think of bats the image of blood-sucking vampires comes to mind. But for robotic researchers, those leathery...

Buried underground along the Swiss - French border is one of the most important scientific research projects ever undertaken. The Large Hadron Collider (LHC) is busy, working to discover the smallest and most intangible pieces of matter and energy that make up our universe. Working...

Researchers have come across an odd phenomenon while studying the properties of quantum physics. Again and again experiments have shown that two linked particles seem to be entangled and what happens to one happens to the other. Surprisingly it doesn't matter if they're one mile...
A look at what scientists learned from smashing ions together inside the Large Hadron Collider
By: W. H. Lindgren
The first two things that scientists learned from smashing very specific lead (Pb 82) heavy ion particles together was that the resulting impacts produced far more particle releases than anticipated, and the temperatures of some "fireballs" reached 18 trillion degrees Fahrenheit, which is about 500...

In the natural universe there are four natural states of matter. The first three are gas, liquid and solid and generally very easy for us to understand as we interact with them regularly. In many ways they are very similar. The fourth is plasma, a...
