A prime number is one that cannot be split up by division. Think of 11. Twice six is 12, three fours are 12. But the only number you can divide 11 by is one, and when you have done that you still have 11 left. Prime numbers lie at the very roots of arithmetic, and have always fascinated those concerned …

It’s a technology that enables people to see how they would look like in the future, based on their habits. Users will have to fill out a questionnaire detailing their lifestyle and upload their images.

Mirages are optical illusions produced by extraordinary atmospheric conditions. They can be non-existent sheets of water or similar visions, inverted or oversized images of distant objects or various other distortions. All are caused by the refraction, or bending, of light rays as they pass through two layers of air with different densities. The differences in density are usually due to …

A micelle is the cluster or aggregated particles formed by associated colloids (substances which, at high concentration, behave as colloidal solutions due to formation of micelles) in solution. Micelle formation takes place above a certain concentration called Critical Micellization Concentration (CMC) and above a particular temperature called Kraft Temperature. Every micelle system has a particular value of CMC. Micelles are …

Memristor is claimed to be the fourth basic element to electrical circuit theory along with the capacitor, resistor and inductor. It was recently discovered in HP Labs. It’s most interesting characteristic is that it remembers the amount of charge that flows through it. So, it is named as memory resistor or memristor. Researchers believe the discovery will pave the way …

People are mammals, and so are lions, elephants, whales, pigs and rabbits. How do we know?
