Electronics: How relays work
By: Edward Matthews
Relays are switches that are operated by electrical signals, as opposed to being operated manually. There are a many different types of these devices, and they each work in a somewhat different manner. The purpose of any relay is to be able to perform a...

In an absolutely scary development, the heaviest antimatter ever found was created in a little copy of the "big bang". The experiment that was conducted near Long Island, New York culminates at least a year of smashing atoms together. According to the National Geographic, the...
Is Time Real or Relative
By: John Traveler
Time, in terms of the greater universal cosmic reality, is unequivocally real. It it were not so, there would be no greater universal cosmic reality, nor a quantum reality which within its bazaar realm might represent the quintessential component of that reality. As Albert Einstein...
An explanation of Newton's three laws of motion
By: Mansoor Alam
Isaac Newton is considered as the finest brain in science the world has ever produced. His discovery in science (then called natural Philosophy) is called Classical Mechanics (or more accurately Newtonian Mechanics). He gave three fundamental laws in Mechanics , called Newton's Laws of Motion. These...

The flow of electric current in a conductive material can be compared to the flow of water through a hosepipe. A motive force is required to cause current to flow in a conductor and the motive force is voltage. The higher the voltage the higher...
How hot air balloons work
By: Mark G Weller
A hot-air balloon flies or rises when the air inside the envelope is heated causing it to be less dense than the surrounding air mass. Since the less dense air is contained within the envelope, the envelope and attached basket rise. The physics of why...

When exploring the possibility of parallel universes, we conclude that Physicist Hugh Everett's many worlds theory isn't scientifically adequate. To illustrate, we note the observational challenges of the many worlds interpretation, where "definite measurements arise from a deterministic wave function evolution that superimposes the state...
Alternative views on String Theory
By: Ray Burke
Noisy Strings: Scientists often use the analogy of quantum strings as being like instrument strings, under tension and vibrating through dimensions. But they never talk about the quantum strings themselves making a sound. This always seemed peculiar. If strings were isolated from the vacuum would...
How to use magnetism to test gemstones and minerals
By: Allan Taylor
The most common magnetic mineral is appropriately named "magnetite" an iron oxide of chemical composition Fe3 O 4. In olden days it was called lodestone because pointy fragments when suspended on a string would line up pointing north and south according to the earth’s...

According to HPPH at www.Hparticles.com/, "Dark matter is a form of matter that does not emit light, absorb light, or scatter light. Its only interactions are gravitational"http://www.astro.ucla.edyu/~wright/glossary.html. The exited H particle-paths due to mass diminution as the subject of...
