What frequency makes you smarter?
What frequency makes you smarter? The highest frequency brain waves are apparently called gamma waves. These waves can have a frequency of anywhere between 25 and 100 Hz. People whose brains produce more gamma waves are said to have greater ability to concentrate, focus and experience higher levels of cognition. Will reading increase IQ? It […]
What is the purpose of a spectrograph?

How does the shockwave of an explosion kill?
How does the shockwave of an explosion kill? Blast Effects Most damage comes from the explosive blast. The shock wave of air radiates outward, producing sudden changes in air pressure that can crush objects, and high winds that can knock objects down. For the most part, a nuclear blast kills people by indirect means rather […]
