Arnold And Mabel Beckman
Arnold Orville Beckman (April 10, 1900 – May 18, 2004) was an American chemist, inventor, investor, and philanthropist. While a professor at California Institute of Technology, he founded Beckman Instruments based on his 1934 invention of the pH meter, a device for measuring acidity (and alkalinity), later considered to have "revolutionized the study of chemistry and biology". He also developed the DU spectrophotometer, "probably the most important instrument ever developed towards the advancement of bioscience". Beckman funded the Shockley Semiconductor Laboratory, the first silicon transistor company in California, thus giving rise to Silicon Valley. After retirement, he and his wife Mabel (1900–1989) were numbered among the top philanthropists in the United States. Early life Beckman was born in Cullom, Illinois, a village of about 500 people in a farming community. He was the youngest son of George Beckman, a blacksmith, and his second wife Elizabeth Ellen Jewkes. He w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cullom, Illinois
Cullom is a village in Livingston County, Illinois, Livingston County, Illinois, United States. Cullom is situated twenty miles east of Pontiac, Illinois, Pontiac which is the county seat, and is one mile west of the Ford County, Illinois, Ford County line. The population was 555 at the 2010 census. History Cullom owes its beginning to the Illinois Central Railroad which reached the village in 1878. The location of the village was established by Frederick Hack who granted a 90 foot right of way across his farm and paid a cash bonus of $4000 to the railroad company. Hack platted and laid out the village and donated forty acres of land on which to build it. The village was named for Shelby Moore Cullom, 17th governor of Illinois. The story was that Mr. Hack wanted the town called Jeffrey after the man who was roadmaster of the Illinois Central Railroad at that time. Jeffrey wanted the town called Hack but he declined the honor. The two men then compromised and called it Cullom. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Institute Of Technology
The California Institute of Technology (branded as Caltech or CIT)The university itself only spells its short form as "Caltech"; the institution considers other spellings such a"Cal Tech" and "CalTech" incorrect.

United States Marines
The United States Marine Corps (USMC), also referred to as the United States Marines, is the maritime land force service branch of the United States Armed Forces responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is one of the eight uniformed services of the United States. The Marine Corps has been part of the U.S. Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers. The history of the Marine Corps began when two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as a se ...

First World War
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Joel Dorman Steele
Joel Dorman Steele (May 14, 1836 – May 25, 1886) was an American educator. He and his wife Esther Baker Steele were important textbook writers of their period, on subjects including American history, chemistry, human physiology, physics, astronomy, and zoology. In the preface to his posthumous ''Popular Physics'', the publisher writes that his books "attained an extraordinary degree of popularity, due to the author's attractive style, his great skill in the selection of material suited to the demands of the schools for which the books were intended, his sympathetic spirit toward both teachers and pupils, and his earnest Christian character, which was exhibited in all his writing." Born May 14, 1836, in Lima, New York, he became a country schoolteacher at the age of 17, leaving that position after an outbreak of typhoid fever killed his mother in 1851. He graduated from Genesee College (which later became Syracuse University) in 1858, and became a school principal in Oswego Co ...

Silicon Transistor
upright=1.4, gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (pink). A transistor is a semiconductor device used to Electronic amplifier, amplify or electronic switch, switch electrical signals and electrical power, power. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Some transistors are packaged individually, but many more are found embedded in integrated circuits. Austro-Hungarian physicist Julius Edgar Lilienfeld proposed the concept of a field-effect transistor in 1926, but it was not possible to actually constru ...
