Graphene: The strongest material in the world Graphene is a material discovered in 2004 by scientists Andrei Gaim and Konstantin Novoselov, who was also awarded the Nobel Prize in Physics in 2010. Disdyastato is the first material (composed namely of a flat set of carbon atoms), and the strongest known material currently on the planet. Also because they are better conductor of electricity than copper, may has revolutionary uses of computers in industry.- Gamers in the future will be in very good physical condition Young video game players try to play a virtual reality game on special bases, in which they have to walk normally to move in the virtual world.
- Sealing a pipe with induction How to seal a pipe with the method of inductive melting. The induction Fusion is an application of Faraday's law, where heat is transferred to a conductive material through a magnetic field without the presence of physical contact. The changing magnetic flux passing through the conductive material causes the current flow in this, which is responsible for the heating of.

- The transformation of the largest beetle in the world The Japanese entomologist Hirofumi Kawano filmed the spectacular transformation of a Hercules beetle Dynastes, the largest in the world along beetle. The opening of the blades of this insect can reach 22 cm. The arsenic size ranges from 6 to 17,50/100 but rarely exceeds 15 cm. The male has two horns. One is the expansion of the chest, and the other is smaller and modular, and this is a "clamp". After the end of many years, the larvae transform into pupa from which emerges an adult beetle.
