DOCTORS SAY 'FRIED CHICKEN IS GOOD FOR YOU' A study published in the International Journal of Sports Nutrition and Exercise Metabolism showed that fast food is just as efficient as a protein bar or sports drink when it comes to glycogen recovery (when you work out, you deplete those stores and they need to be replinished afterwards to optimize muscle repair and growth.) The study, which was ...

- Edison had tried to convince everyone that Westinghouse's AC current was unsafe and was delighted when New York State introduced the electric chair, which required alternating current. After New York, the next state to introduce the electric chair was Ohio in April 1897, with Massachusetts following two years later. New Jersey changed to electrocution in December 1907, Virginia in January 1908, and North Carolina in February 1910.

- In 1831, the English scientist Michael Faraday discovered that an electrical current could be induced in a copper wire by a moving magnetic field. This led to two crucial inventions: the dynamo and the electric motor.t had been evolved by many Europeans and in 1852 the first 'modern' light bulb was invented. Edison bought his patent in the 1870s from other inventors and experimented with different filaments. Quite ironic as this pages is about the misconception of who first harnessed electricity.
