Waldo K. Lyon
Waldo Kampmeier Lyon (May 19, 1914 – May 5, 1998) was the founder and chief research scientist for the U.S. Navy of the Arctic Submarine Laboratory at the Naval Electronics Laboratory. He retired in 1996 after 55 years of government service. During his career he advised top Navy officials on essential matters of national defense and was personally thanked by Presidents Eisenhower and Kennedy for his efforts. Military career For 51 years, Lyon worked for Space and Naval Warfare Systems Center, San Diego (SSC San Diego) and its predecessor organizations. Lyon started work there less than a year after its June 1940 establishment as the Navy Radio and Sound Lab, as their first Ph.D. physicist. He was charged with forming and directing initial efforts of the Sound Division. The lab was used during World War II for testing, repairing and modifying submarine equipment and harbor defense systems in the Pacific Ocean. During the war, German U-boats in the Gulf of St. Lawrenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientist
A scientist is a person who conducts Scientific method, scientific research to advance knowledge in an Branches of science, area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century in science, 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have Terminal degree, advanced degrees in an area of science and pursue careers in various Sector (economic), sectors of the economy such ...

Bathyscaphe Trieste
''Trieste'' is a Swiss-designed, Italian-built deep-diving research bathyscaphe which reached a record depth of about in the Challenger Deep of the Mariana Trench near Guam in the Pacific. On 23 January 1960, Jacques Piccard (son of the boat's designer Auguste Piccard) and US Navy Lieutenant Don Walsh achieved the goal of Project Nekton. It was the first crewed vessel to reach the bottom of the Challenger Deep. Design ''Trieste'' consisted of a float chamber filled with gasoline (petrol) for buoyancy, with a separate pressure sphere to hold the crew. This configuration (dubbed a "bathyscaphe" by the Piccards) allowed for a free dive, rather than the previous bathysphere designs in which a sphere was lowered to depth and raised again to the surface by a cable attached to a ship. ''Trieste'' was designed by the Swiss scientist Auguste Piccard and originally built in Italy. His pressure sphere, composed of two sections, was built by Acciaierie Terni. The upper part was manufactu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Presidential Unit Citation (US)
The Presidential Unit Citation (PUC), originally called the Distinguished Unit Citation, is awarded to units of the uniformed services of the United States, and those of allied countries, for extraordinary heroism in action against an armed enemy on or after 7 December 1941 (the date of the Attack on Pearl Harbor and the start of American involvement in World War II). The unit must display such gallantry, determination, and '' esprit de corps'' in accomplishing its mission under extremely difficult and hazardous conditions so as to set it apart from and above other units participating in the same campaign. Since its inception by President Franklin D. Roosevelt with the signing of Executive Order 9075 on 26 February 1942, retroactive to 7 December 1941, to 2008, the Presidential Unit Citation has been awarded in conflicts such as World War II, the Korean War, the Vietnam War, Iraq War, and the War in Afghanistan. The collective degree of valor (combat heroism) against an armed e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
President's Award For Distinguished Federal Civilian Service
Established by President Dwight D. Eisenhower on 27 June 1957 by , the President's Award for Distinguished Federal Civilian Service was created to allow the President to recognize civilian officers or employees of the federal government who have made contributions "so outstanding that the officer or employee is deserving of greater public recognition than that which can be accorded by the head of the department or agency in which he is employed." President John F. Kennedy in directed that potential recipients of the award are recommended to the President by the Distinguished Civilian Service Awards Board, who also had responsibility for recommending people to be awarded the Presidential Medal of Freedom. , by Jimmy Carter, abolished the Distinguished Civilian Service Awards Board and turned over the responsibility for recommending recipients to the Chairman of the United States Civil Service Commission. This executive order was subsequently modified again by Jimmy Carter in wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of Defense Distinguished Civilian Service Award
The Department of Defense Distinguished Civilian Service Award is the highest civilian award given by the United States Department of Defense.

Acoustics
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration, sound, ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an Acoustical engineering, acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing (sense), Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more. Likewise, animal species such as songbirds and frogs use sound and hearing as a key element of mating rituals or for marking territories. Art, ...

Art Roshon
Art is a diverse range of human activity, and resulting product, that involves creative or imaginative talent expressive of technical proficiency, beauty, emotional power, or conceptual ideas. There is no generally agreed definition of what constitutes art, and its interpretation has varied greatly throughout history and across cultures. In the Western tradition, the three classical branches of visual art are painting, sculpture, and architecture. Theatre, dance, and other performing arts, as well as literature, music, film and other media such as interactive media, are included in a broader definition of the arts. Until the 17th century, ''art'' referred to any skill or mastery and was not differentiated from crafts or sciences. In modern usage after the 17th century, where aesthetic considerations are paramount, the fine arts are separated and distinguished from acquired skills in general, such as the decorative or applied arts. The nature of art and related concepts, such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elasticity (physics)
In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate loads are applied to them; if the material is elastic, the object will return to its initial shape and size after removal. This is in contrast to ''plasticity'', in which the object fails to do so and instead remains in its deformed state. The physical reasons for elastic behavior can be quite different for different materials. In metals, the atomic lattice changes size and shape when forces are applied (energy is added to the system). When forces are removed, the lattice goes back to the original lower energy state. For rubbers and other polymers, elasticity is caused by the stretching of polymer chains when forces are applied. Hooke's law states that the force required to deform elastic objects should be directly proportional to the distance of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brine
Brine is a high-concentration solution of salt (NaCl) in water (H2O). In diverse contexts, ''brine'' may refer to the salt solutions ranging from about 3.5% (a typical concentration of seawater, on the lower end of that of solutions used for brining foods) up to about 26% (a typical saturated solution, depending on temperature). Brine forms naturally due to evaporation of ground saline water but it is also generated in the mining of sodium chloride. Brine is used for food processing and cooking (pickling and brining), for de-icing of roads and other structures, and in a number of technological processes. It is also a by-product of many industrial processes, such as desalination, so it requires wastewater treatment for proper disposal or further utilization (fresh water recovery). In nature Brines are produced in multiple ways in nature. Modification of seawater via evaporation results in the concentration of salts in the residual fluid, a characteristic geologic deposit call ...

Arctic Ocean
The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It spans an area of approximately and is known as the coldest of all the oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. It has been described approximately as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing World Ocean. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N. The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features: the Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is t ...
