In the U.S., a system of an early warning of natural disasters

In the U.S., a system of notification of imminent natural disasters Facts

University of Arkansas researchers have developed an early warning system for natural disasters, with which U.S. residents will be given full information about potentially dangerous places and required navigational assistance to those who are directly in the epicenter of events.

Network to notify the state of emergency is a self-regulating powered by solar panels system, which ensures long-term continuous operation, even if the electric power system, or wireless connection broke down. Users will get the most important information to mobile phones, personal digital assistants, tablets or laptops.

Snezhinskiy scientists have developed a device for checking the items on the strength of

Turn the illusion into reality. Snezhinskiy scientists have developed a holographic device that scans a laser on the subject of strength, whether it is football, car seat or a rocket engine.

It can be easily fooled by television camera, to distinguish from the fake currency note and just to please the eye. Scientists used to believe that hard numbers, not illusions still could not resist the awesome optical phenomenon — holography. "At the time, the experimenters have seen that the object is covered golografiruemy stripes, and could not understand what was going on, trying to get rid
