Newton’s first law of motion was the first of three laws discovered by Sir Isaac Newton. He presented these laws in his book “Principia Mathematica Philosophiae Naturalis” in 1686. The laws of motion describe how objects move. Newton’s first law…

Film Theory Firstly there are different thicknesses of lubrication that can be applied. They are the 1) thick-film lubrication, 2) thin-film lubrication, 3) mixed-film lubrication, 4) boundary-film lubrication and 5) solid-film lubrication. In thick-film regime, the lubricant completely separates the…

Science fiction writers often look for a device which can transport objects through space and time. A wormhole is a theoretical device which might allow such a transport. According to theoretical physics there might be a shortcut through spacetime which…

A wormhole is described as any structure connecting two regions of space-time which are otherwise very far apart or unrelated, somewhat like a tunnel with two ends where each end is in a separate point of space. Some scientists have…

Physicists recognize four forces of nature. These are identified as interactions that include all known phenomena in nature. Some of the four are easy to recognize because they are seen every day. Others are happening all around, but not necessarily seen….

The Russian Federation’s space program has run into hard times. A series of spectacular failures has recently been capped by the malfunction of the country’s much vaunted Mars-Phobos mission, GRUNT. After failing to boost from Earth orbit, the advanced space…

To understand AC or DC power, we need to understand the nature of electricity itself. Electricity is the movement of free electrons between areas of different potential through a conductive medium. Electrons have a negative charge. Free electrons are those…

Look at the streaming vapor following a jet; look closely at the lifting of an unbelievably heavy space shuttle and imagine what science creates these spectacles: rocketry. For some of us, model rocket kits are the closest we’ll come to space,…

In 1995 Leonard Susskind a Professor of Theoretical Physics at Stanford University published an unusual paper. He suggested that the entire universe might be a hologram in which people are just seeing a projection of the real thing. His theory is…
