15.5 - Let There Be Light(s)
Physicist Theodore Maiman uses a core of man-made ruby to create the first successful LASER (an acronym for Light Amplification by the Stimulated Emission of Radiation). It was first demonstrated on May 16, 1960. The invention has an immediate effect on pop culture, heavily promoted in science fiction books and movies. Read a book with all the letters of LASER found in the TITLE only. Subtitles are excluded.
