Theodore Lyman IV
Theodore Lyman IV (; November 23, 1874 – October 11, 1954) was a U.S. physicist and spectroscopist, born in Boston. He graduated from Harvard in 1897, from which he also received his Ph.D. in 1900. Career Lyman became an assistant professor in physics at Harvard, where he remained, becoming full professor in 1917, and where he was also director of the Jefferson Physical Laboratory (1908–17). He made important studies in phenomena connected with diffraction gratings, on the wavelengths of vacuum ultraviolet light discovered by Victor Schumann and also on the properties of light of extremely short wavelength, on all of which he contributed valuable papers to the literature of physics in the proceedings of scientific societies. Military service During World War I he served in France with the American Expeditionary Force, holding the rank of major of engineers.

American Expeditionary Force
The American Expeditionary Forces (A. E. F.) was a formation of the United States Army on the Western Front of World War I. The A. E. F. was established on July 5, 1917, in France under the command of General John J. Pershing. It fought alongside French Army, British Army, Canadian Army, New Zealand Army and Australian Army units against the Imperial German Army. A small number of A. E. F. troops also fought alongside Italian Army units in that same year against the Austro-Hungarian Army. The A. E. F. helped the French Army on the Western Front during the Aisne Offensive (at the Battle of Château-Thierry and Battle of Belleau Wood) in the summer of 1918, and fought its major actions in the Battle of Saint-Mihiel and the Meuse-Argonne Offensive in the latter part of 1918. Formation President Woodrow Wilson initially planned to give command of the A. E. F. to Gen. Frederick Funston, but after Funston's sudden death, Wilson appointed Major General John J. Pershing in May ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Percy Williams Bridgman
Percy Williams Bridgman (April 21, 1882 – August 20, 1961) was an American physicist who received the 1946 Nobel Prize in Physics for his work on the physics of high pressures. He also wrote extensively on the scientific method and on other aspects of the philosophy of science. The Bridgman effect, the Bridgman–Stockbarger technique, and the high-pressure mineral bridgmanite are named after him. Biography Early life Bridgman was born in Cambridge, Massachusetts, and grew up in nearby Auburndale. Bridgman's parents were both born in New England. His father, Raymond Landon Bridgman, was "profoundly religious and idealistic" and worked as a newspaper reporter assigned to state politics. His mother, Mary Ann Maria Williams, was described as "more conventional, sprightly, and competitive". Bridgman attended both elementary and high school in Auburndale, where he excelled at competitions in the classroom, on the playground, and while playing chess. Described as both shy and ...

Wallace Clement Sabine
Wallace Clement Sabine (June 13, 1868 – January 10, 1919) was an American physicist who founded the field of architectural acoustics. Sabine was the architectural acoustician of Boston's Symphony Hall, widely considered one of the two or three best concert halls in the world for its acoustics. Early life Wallace Clement Sabine was born on June 13, 1868 in Richwood, Ohio. He graduated with a Bachelor of Arts from Ohio State University in 1886 at the age of 18. He then attended Harvard University and graduated with a Master of Arts in 1888. His sister was Annie W. S. Siebert.

Military Order Of The Loyal Legion Of The United States
The Military Order of the Loyal Legion of the United States (MOLLUS), or simply the Loyal Legion is a United States patriotic order, organized April 15, 1865, by three veteran officers of the Army. The original membership was composed of members of the Army, Navy, or Marine Corps of the United States, who had served during the American Civil War as commissioned officers in Federal service, or who had served and thereafter been commissioned, and who thereby "had aided in maintaining the honor, integrity, and supremacy of the national movement" during the Civil War. The Loyal Legion was formed by in response to rumors from Washington of a conspiracy to destroy the Federal government by assassination of its leaders, in the immediate aftermath of the assassination of President Abraham Lincoln. The founding members stated their purpose as the cherishing of the memories and associations of the war waged in defense of the unity and indivisibility of the Republic; the strengthening of th ...

Moon
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic period ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyman (crater)
Lyman is a lunar impact crater that lies in the southern hemisphere on the far side of the Moon. It is located to the south of the huge walled plain Poincaré, and to the northeast of Schrödinger, another walled plain. To the east-southeast is the larger crater Minnaert. The rim of Lyman has not been significantly worn and has a well-defined edge and interior features that have not been eroded through impacts. The perimeter is roughly circular with outward bulges along the southern and eastern edges where slumping has occurred. Around much of the interior edge the unconsolidated material has collapsed, forming a ring-shaped pile around the edge of the interior floor. There are a few terrace Terrace may refer to: Landforms and construction * Fluvial terrace, a natural, flat surface that borders and lies above the floodplain of a stream or river * Terrace, a street suffix * Terrace, the portion of a lot between the public sidewalk an ...s along parts of the inner wall.
