Advanced telescope on Hawaii volcano

Work on the 30-meter telescope, the diameter of which is three times greater than the existing telescope, due to start in April 2014, an extinct volcano in the Hawaiian Mona Ki.

Studies using this telescope will enable astronomers to study the stars and other objects across the solar system, 

The Doppler Effect and long-planet

We are all familiar with the Doppler Effect, even if you do not know the term. Today, scientists have found an alternative explanation for the phenomenon when the sound or the light spinning object is scattered. This discovery could help astronomers to measure the rotation of the planet, or even improve the performance of wind turbines.

Here is what the principle of the Doppler Effect: when the object emitting the noise is moving towards its sound waves converge together and produce a higher frequency. Conversely, when the subject moves away, the sound waves are scattered. The faster the object moves, the sharper the frequency difference.

Surviving a Zombie Apocalypse: Just Do the Math

This equation could spell your doom: (bN)(S/N)Z = bSZ. That is, if you ever found yourself in the midst of a zombie pandemic.

That's because the calculation describes the rate of zombie transmission, from one walking dead individual to many, according to its creators, Robert J. Smith?, a mathematics professor at the University of Ottawa who spells his name with a "?" at the end, and his students.
