After studying physics, he began research into methods of producing concentrated light beams. Earlier workers had produced the maser, which was used in radio astronomy to amplify long- wavelength radiation. In 1960, Maiman produced the most intense light that had ever been produced. He called his machine the laser. Laser GEORGE MANBY 1765-1854 EAR ARLY fire extinguishers in the 1730s were just glass balls of water that were thrown on fires. Although widely advertised, they were not much used. In 1816, an English army captain named George Manby vowed to develop a portable fire fighter after watching a fire rage on the fifth floor of a building, where hoses could not reach. He invented an extinguisher, similar to modern water models, in which compressed air forced water out of a cylinder. Fire Extinguisher N P R S W NWISC
