29 Jan Laser
According to Wikipedia, “A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word “laser” is an acronym for “light amplification by stimulated emission of radiation“. The first laser was built in 1960, Lasers are used in optical disc drives, laser printers, barcode scanners, DNA sequencing instruments, fiber-optic, semiconducting chip manufacturing (photolithography), and free-space optical communication, laser surgery and skin treatments, cutting and welding materials, military and law enforcement devices for marking targets and measuring range and speed, and in laser lighting displays for entertainment.”
Clearly, a laser can do many extraordinary things relative to a flashlight. Yet, for making our way through a dark thicket, a flashlight is better. Likewise, those with a laser-sharp mind are best not deployed to solve simple tasks. For example, undoubtedly Albert Einstein was extraordinarily brilliant, yet forgot the basic concept of gravity (what goes up must go down) as he lost most of the money he received with his Noble Prize in the stock market in the 1920s.
