Nobska Light , a lighthouse at Nobska Point , is operated by the United States Coast Guard , and the accompanying house is the home of the commander of the Coast Guard base at Little Harbor. The local landmark The Knob is a rocky outcropping that overlooks Buzzards Bay and Quisset Harbor. It is a part of the privately owned Salt Pond bird sanctuaries. According to

156-479: A priority dispute with Lewis over this work; Langmuir's presentation skills were largely responsible for the popularization of the theory, although the credit for the theory itself belongs mostly to Lewis. While at General Electric from 1909 to 1950, Langmuir advanced several fields of physics and chemistry , inventing the gas-filled incandescent lamp and the hydrogen welding technique . The Langmuir Laboratory for Atmospheric Research near Socorro, New Mexico ,

Hispanic or Latino of any race were 0.97% of

546-788: The International Solvay Institute for Physics in Belgium. He joined Katharine B. Blodgett to study thin films and surface adsorption. They introduced the concept of a monolayer (a layer of material one molecule thick) and the two-dimensional physics which describe such a surface. In 1932 he received the Nobel Prize in Chemistry "for his discoveries and investigations in surface chemistry ." In 1938, Langmuir's scientific interests began to turn to atmospheric science and meteorology . One of his first ventures, although tangentially related,

585-701: The Partial Recombination of Dissolved Gases During Cooling" ( German : Ueber partielle Wiedervereinigung dissociierter Gase im Verlauf einer Abkühlung ). He later did postgraduate work in chemistry. Langmuir then taught at Stevens Institute of Technology in Hoboken, New Jersey , until 1909, when he began working at the General Electric research laboratory ( Schenectady, New York ). His initial contributions to science came from his study of light bulbs (a continuation of his PhD work). His first major development

Morgan and Company ; Joseph Lee, a partner in Lee, Higginson & Co. ; and Franklin A. Park, an executive of Singer Sewing Machine . Other notable businessmen established homes on Gansett Point, Nobska Point, and at Quissett Harbor, further from the village center. Irving Langmuir ,

741-619: The bulb. His assistant in vacuum tube research was his cousin William Comings White . As he continued to study filaments in vacuum and different gas environments, he began to study the emission of charged particles from hot filaments ( thermionic emission ). He was one of the first scientists to work with plasmas , and he was the first to call these ionized gases by that name because they reminded him of blood plasma . Langmuir and Tonks discovered electron density waves in plasmas that are now known as Langmuir waves . He introduced

780-423: The concept of electron temperature and in 1924 invented the diagnostic method for measuring both temperature and density with an electrostatic probe, now called a Langmuir probe and commonly used in plasma physics. The current of a biased probe tip is measured as a function of bias voltage to determine the local plasma temperature and density. He also discovered atomic hydrogen , which he put to use by inventing

819-566: The corner of his bedroom, and he was content to answer the myriad questions that Irving would pose. Langmuir's hobbies included mountaineering , skiing , piloting his own plane, and classical music . In addition to his professional interest in the politics of atomic energy, he was concerned about wilderness conservation. Langmuir attended several schools and institutes in America and Paris (1892–1895) before graduating high school from Chestnut Hill Academy (1898), an elite private school located in

There were 459 households, out of which 14.8% had children under the age of 18 living with them, 39.7% were married couples living together, 5.4% had a female householder with no husband present, and 53.6% were non-families. 40.5% of all households were made up of individuals, and 17.9% had someone living alone who was 65 years of age or older. The average household size was 1.94 and

1014-404: The process. He also discovered that twisting the filament into a tight coil improved its efficiency. These were important developments in the history of the incandescent light bulb . His work in surface chemistry began at this point, when he discovered that molecular hydrogen introduced into a tungsten-filament bulb dissociated into atomic hydrogen and formed a layer one atom thick on the surface of

1053-533: The scientist, also lived in Woods Hole and died there on August 16, 1957. Before 1898, the Woods Hole Yacht Club was formed. In 1899, the Woods Hole Golf course was started. Around 1919, it was expanded to 18 holes. In 1976, The Woods Hole Foundation was created. The eminent Hungarian born biochemist and Nobel prize laureate, Albert Imre Szent-Györgyi de Nagyrápolt died in Woods Hole in 1986. Woods Hole

Students regularly visit ecosystems around

1131-519: The term " pathological science ", describing research conducted with accordance to the scientific method , but tainted by unconscious bias or subjective effects. This is in contrast to pseudoscience , which has no pretense of following the scientific method. In his original speech, he presented ESP and flying saucers as examples of pathological science; since then, the label has been applied to polywater and cold fusion . His house in Schenectady,

1287-756: Was a refutation of the claim of entomologist Charles H. T. Townsend that the deer botfly flew at speeds of over 800 miles per hour. Langmuir estimated the fly's speed at 25 miles per hour. After observing windrows of drifting seaweed in the Sargasso Sea he discovered a wind-driven surface circulation in the sea. It is now called the Langmuir circulation . During World War II , Langmuir and Research Associate Vincent J Schaefer worked on improving naval sonar for submarine detection, and later to develop protective smoke screens and methods for deicing aircraft wings. This research led him to theorize and then demonstrate in

1326-505: Was an American chemist , physicist , and engineer . He was awarded the Nobel Prize in Chemistry in 1932 for his work in surface chemistry . Langmuir's most famous publication is the 1919 article "The Arrangement of Electrons in Atoms and Molecules" in which, building on Gilbert N. Lewis 's cubical atom theory and Walther Kossel 's chemical bonding theory, he outlined his "concentric theory of atomic structure". Langmuir became embroiled in

1365-491: Was designated a National Historic Landmark in 1976. Langmuir was married to Marion Mersereau (1883–1971) in 1912 with whom he adopted two children: Kenneth and Barbara. After a short illness, he died in Woods Hole, Massachusetts from a heart attack on August 16, 1957. His obituary ran on the front page of The New York Times . On his religious views, Langmuir was an agnostic. According to author Kurt Vonnegut , Langmuir

1404-451: Was eleven, it was discovered that he had poor eyesight. When this problem was corrected, details that had previously eluded him were revealed, and his interest in the complications of nature was heightened. During his childhood, Langmuir was influenced by his older brother, Arthur Langmuir. Arthur was a research chemist who encouraged Irving to be curious about nature and how things work. Arthur helped Irving set up his first chemistry lab in

1443-461: Was formed from the New Bedford, Martha's Vineyard, and Nantucket Steamboat Company, which in turn was a consolidation of earlier companies dating to the early 19th century, just before the railroad arrived. Much of Woods Hole centers around the enclosed harbor of Eel Pond. The Eel Pond Bridge, a bascule drawbridge at the mouth of the harbor, allows boats to enter and exit the harbor according to
