The Special Theory of Relativity (distinguished from Galilean Relativity, a limiting case of SR or General Relativity, a generalization of SR) is based on two postulates. A postulate is a statement assumed to be true without proof. The validity of this assumption is measured by...

Semiconductors are materials that would be electrical insulators at zero kelvin, but at room temperature are merely poor conductors. A thorough understanding of semiconductor theory requires considerable effort in developing a background in physics, however, a basic picture can be developed with a little thought...
Quantum Physics is Time Travel Theoretically Feasible
By: Quinn Gibson
I find no compelling philosophical reason why Quantum Mechanics makes time travel any more or less theoretically feasible than before serious Quantum science got underway. Of course, the entire intricate workings of the world on the Quantum level are so patently bizarre that such fancies...
Quantum Physics is Time Travel Theoretically Feasible
By: David Heidler
No I don't think time travel is possible. Here is why I think this is so without getting to "scientific" about it. The fastest speed ever measured in the universe is that of the photon i.e. light particles. As far as we have been...
Quantum Physics is Time Travel Theoretically Feasible
By: V. Kumar
Please read this carefully - "there is nothing that we know, which would make it impossible for us to travel in time".This may not be enough to say that time travel is theoretically feasible, but what it does mean is that there is nothing...
Quantum Physics is Time Travel Theoretically Feasible
By: Maximilian Ringwald
When asking if time travel is theoretically feasible, one must ask both whether it is conceptually possible, and whether it is attainable.Before it can be said that time travel is theoretically possible, one must first choose a theory to base the prediction on. In...

Sir Isaac Newton: It's a Wonderful World of MotionMost folks know who Isaac Newton is. However, how many of us can state his three laws of motion? Well, here is your chance to amaze your friends-at least, yourself-with a bit of knowledge. I, personally, can't...

There are many theories regarding the nature of dark matter, but one thing is clear: it's physical properties are very different to those of "normal" baryonic matter. For one thing it only interacts with baryonic matter thorough gravity and the weak nuclear force. It's lack...

After the Big Bang, the universe began to expand. This expansion was mostly constant until around 4.5 billion years ago, when the expansion suddenly increased. Today, the universe is still expanding, but at an increasing rate. Dark Energy is the concept that explains the...

Magnify an ordinary curve, like a parabola, and no new detail appears. As one magnifies it further and further, a line becomes a very good approximation. Most curves have this property, and likewise most surfaces can be very well approximated by a single plane at...
