Introduction/Purpose: I wanted to know if I could make magnetism.
Hypothesis/Questions: Is it possible to create magnetism using man-made materials? If iron-bearing metal is subject to an electric current, then magnetism will be produced.
Materials: a 6-volt battery, 10 feet of wire, a metal rod, a switch, and paper clips
Procedure: I went to Home [...]

The availability of magnets superconducting strongest interest to industrial and doctors but particle physicists. The U.S. government has allocated $ 4 million for the development of magnets based on bismuth, capable of intensity of magnetic fields at least twice those of the LHC.For the operation of particle accelerators like the Tevatron or LHC, it is [...]
A test of loop quantum gravity and superstring with Fermi
| No Reviews |
Overall Rating:

Under some models of gravitational quantum inspired by loop quantum gravity or string theory, the theory of relativity Einstein no longer applies. Some of these models have recently been refuted by recent observations of a surge in short gamma-ray satellite Fermi. An initial report may already be prepared quickly but this is just the beginning. [...]

His fate remained for a time uncertain but the Alpha Magnetic Spectrometer (AMS) actually go to space aboard a recent shuttle. His goal, track the antimatter cosmic missing, discovering the nature of dark matter, without any mention of mini black holes .Physics accelerators on Earth has limits and it is a safe bet that for [...]
One can observe the molecules under the microscope

It was already known imaging and manipulating atoms but thanks to researchers from IBM, it becomes possible to observe molecules. The origin of this achievement, a discovery made by chance … The first images of molecules were obtained with pentacene, in the circumstances, it is true, quite delicate. IBM continues its conquest of the nano [...]

Researchers at the University of California, Berkeley, have created the smallest laser semiconductors in the world. Emitting in the visible range, it is smaller than a protein! It is now 49 years that we can do the lasers in the optical domain, but advances in nanotechnology now allow us to miniaturize the device became legendary. [...]

Even if miracles were not achieved, patients suffering from Parkinson’s disease or paralysis could expect improvements in their condition in the near future thanks to carbon nanotubes, when adverse reactions are those hopes came to cool. But researchers now think how to get rid of it. We remember the hopes which had been formed some [...]
The radio quasars confirm general relativity
| No Reviews |
Overall Rating:

For many physicists, the theory of general relativity is the most beautiful theories. Unfortunately, his predictions are sometimes difficult to compare with those of alternative theories of gravitation. The recent observation of the deflection due to the Sun, radio waves emitted by quasars is a new way to eliminate competing theories … or Einstein’s theory [...]
Are there fragments of neutron stars in the lunar soil
| No Reviews |
Overall Rating:

The so-called strange matter, a hypothetical state, would be inside the neutron stars or in the form of “nuggets of quarks,” created in the early history of the universe. Such material could be trapped in the lunar soil. But recent research, using a spectrometer mass remain negative for now.
