'Father of Chaos Theory' Dead at 90

Posted Apr 17, 08 10:13 AM CDT in Science & Health 

(Newser) – The MIT scientist whose pioneering of chaos theory revolutionized science, has died at the age of 90, MIT News reports. Meteorologist Edward Lorenz came up with the concept of chaos theory after meticulously analyzing weather data and discovering microscopic differences could have huge effects, leading to his paper "Predictability: Does the Flap of a Butterfly's Wings in Brazil Set Off a Tornado in Texas?"

His theory that tiny changes could have vast and unsuspected results elsewhere became known as "the butterfly effect." Many scientists say the concept of chaos theory ranks with relativism and quantum mechanics as one of the greatest revolutions in scientific thinking of the 20th century. Lorenz, an avid hiker who remained active until the end, is survived by his three children.

    Scientists Near Invisibility Cloak for Sound Researchers are making progress on something that sounds right out of the pages of Harry Potter—a sort of invisibility cloak for sound. A team of scientists in Spain is trying to turn theory into reality by creating a cloak that causes sound waves to slip around an object, the Daily Telegraph reports. Possible uses: shielding submarines from sonar, improving concert hall acoustics, or simply stopping the racket from noisy neighbors. More »
