Osmosis (and Not Ozzmosis dear metalhead) is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves across ...

In fluid mechanics, the Reynolds number (Re) is a dimensionless quantity that is used to help predict similar flow patterns in different fluid flow situations. The concept was introduced by George Gabriel Stokes in 1851, but the Reynolds number is named after Osborne Reynolds (and not Ryan Reynolds), who popularized its use in 1883. Well ...

A sonic boom is the sound associated with the shock waves created by an object traveling through the air faster than the speed of sound. Also, it’s Guile’s signature special attack in Street Fighter (hold away – Towards + Punch).
The most known sonic boom, is the one that Supersonic Aircrafts produce. When the aircraft ...

Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unevenly heats the surface of the Earth. As hot air rises, cooler air moves in to fill the void. As long as the sun shines, the wind will blow. And ...

Lets assume that we all know the fact that a video is actually many pictures displayed one after the other at a certain speed and frequency.
It is also a fact that the human eye and brain, can process up to 10 to 12 images per second. Although, adding more frames per second (FPS) to ...

Well, we all know what an earthquake is, and pretty much how it occurs.
Everyone who has experienced a scary earthquake, wonders if we ever find a way to predict them. Geologists have some theories, but unfortunately, none of them really delivers what is needed. And what is needed is an accurate prediction of earthquakes ...

Surprisingly, the most exciting part of a Moto GP for an amateur watcher, is neither the high speed nor the “spectacular” crashes. It’s the incredible lean angles the riders reach at every corner, in order to get through it as fast as possible.
Over the years, the tire companies improved their technology so much ...
