Theodore Harold Maiman developed, demonstrated and patented the world's first laser in 1960. Maiman was born in Los Angeles, California, where in his teens, he earned college money by repairing electrical appliances and radios.[2] He attended the University of Colorado and received a B.S. in engineering physics in 1949 then went on to do graduate work at Stanford University, where he received an M.S. in electrical engineering in 1951 and a Ph.D. in physics in 1955. His doctoral thesis in experimental physics, taken under the direction of Willis Lamb, involved detailed microwave-optical measurements of fine structure splittings in excited helium atoms. Maiman's laser, based on a synthetic ruby crystal grown by Dr. Ralph L. Hutcheson, was first operated on 16 May 1960 at Hughes Research Laboratories in Malibu, California. After a protracted legal battle, some key laser patents were awarded to Gordon Gould. A travesty of justice. Dr. Maiman's patent that demonstrates the first laser has never been in question. After leaving Hughes, Maiman joined Quantatron where he was in charge of the laser activities. In 1962 Maiman became president of the newly formed Korad Corporation, a wholly owned subsidiary of Union Carbide. Union Carbide bought the laser assets owned by Quantatron. Korad was devoted to the research, development, and manufacture of lasers. All minority owned stock of Korad Corporation was exchanged for Union Carbide stock during the first five years. Not wishing to continue working for Union Carbide, he formed Maiman Associates in 1968. Due to his work on the laser, he was twice nominated for a Nobel Prize and was given membership in both the National Academies of Science and Engineering.[3] He received the Oliver E. Buckley Prize in 1966. He was the recipient of the 1983/84 Wolf Prize in Physics, and was inducted into the National Inventors Hall of Fame that same year.
h
V=(πD2/4)h where D is the diameter of the 55 gallon drum and h is the height of the oil. Or if you prefer V=(2πr2h where r is the radius of the drum and h is as above.
American society of mechanical engineers has a classification of pressure vessels. Certain type of the boilers have H stamp according their classification, and this stamp is required by local authorities in order to get boiler approved for installation.

the 1st optical laser
July 11, 1927 - May 5, 2007
The first laser was built by Theodore H. Maiman in 1960 at Hughes Research Laboratories. The laser used a ruby crystal as the gain medium and produced a red laser beam.
American physicist Theodore Maiman constructed the first working laser in 1960.But research started in 1958
Theodore H. "Ted" Maiman at Hughes Research Laboratories on May 16, 1960
He was 35 when he made the laser so that would make him 34 before he made it
The laser pointer was invented by Theodore H. Maiman in 1960. Maiman was an American physicist who developed the first working laser technology using a ruby crystal.
The invention of laser lights is attributed to Theodore H. Maiman, who built the first working laser in 1960 using a synthetic ruby crystal. His groundbreaking work paved the way for the widespread use of lasers in various fields such as communication, medical treatments, and entertainment.
The first working laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories. It was based on the concept of a maser (microwave amplification by stimulated emission of radiation) with the wavelengths of light shrunk to the optical range.
