This year the Nobel Prize in Physics has been shared by three pioneer scientists working in the field of Lasers. Arthur Ashkin of the USA is an American. He is at the age of 96 the oldest man ever to win the coveted award. He has invented optical tweezers that grab particles, atoms and molecules with laser beam fingers. With this he was able to use the radiation pressure of light to move physical objects. In 1987, came a major breakthrough when Ashkin used the tweezers to capture living bacteria without harming them. Dr. Ashkin made his discovery while working at AT & T Bell Laboratories, USA from 1952 to 1991. He has been awarded one half of the nine million Swedish Kronor (about $1.01 million or 870,000 Euros).
