Felix Zandman
Felix Zandman ( pl, Feliks Zandman; May 7, 1928 – June 4, 2011) was a Polish-born American entrepreneur and founder of Vishay Intertechnology – one of the world's largest manufacturers of electronic components. From 1946 to 1949 he studied in France at the University of Nancy physics and engineering. In parallel, he was enrolled in a Grande école of engineering Ensem ('' École nationale supérieure d'électricité et de mécanique''). He received a Ph.D. at the Sorbonne as a physicist on a subject of photoelasticity. He was awarded the Edward Longstreth Medal from the Franklin Institute in 1962.

Grodno Ghetto
The Grodno Ghetto ( pl, getto w Grodnie, be, Гродзенскае гета, he, גטו גרודנו) was a Nazi ghetto established in November 1941 by Nazi Germany in the city of Grodno for the purpose of persecution and exploitation of Jews in Western Belarus. The ghetto, run by the SS, consisted of two interconnected areas about 2 km apart. Ghetto One was established in the Old Town district, around the synagogue (''Shulhoif''), with some 15,000 Jews crammed into an area less than half a square kilometre. Ghetto Two was created in the Slobodka suburb, with around 10,000 Jews incarcerated in it. Ghetto Two was larger than the main ghetto but far more ruined. The reason for the split was determined by the concentration of Jews within the city and less need to transfer them from place to place. Their situation had considerably worsened with the ghettos' locations highly inadequate in terms of sanitation, water and electricity. The separation of the ghettos would later ...

March Of The Living
The March of the Living ( he, מצעד החיים, ) is an annual educational program which brings students from around the world to Poland, where they explore the remnants of the Holocaust. On Holocaust Memorial Day observed in the Jewish calendar (), thousands of participants march silently from Auschwitz to Birkenau, the largest Nazi concentration camp complex built during World War II. History The program was established in 1988 and takes place annually for two weeks around April and May, immediately following Passover. Marchers have come from over 50 countries, as diverse as United States, Canada, Australia, New Zealand, China, Estonia, Panama, Mexico, Argentina, Brazil, Hungary, and Turkey. The Israeli founders of the March of the Living were politician Avraham Hirschson educator Dr. Shmuel Rosenman, and attorney Baruch Adler. They were assisted in the early years by Jewish communal leaders and philanthropists from the United States (Alvin Schiff, Gene Greenzweig, Dr. Da ...

Society For Experimental Mechanics
Society for Experimental Mechanics (SEM) is a professional organization for engineers and scientists studying the design and implementation of experiments to characterize materials, structures, and systems. Formed in 1943 as the Society for Experimental Stress Analysis (SESA), early work focused on methods such as photoelasticity and strain gages. Society historical records refer to the society as SESA through the 1984 Fall SESA meeting in Milwaukee, WI and start referring the society as SEM with the 1985 Spring SEM meeting in Las Vegas, NV. The society has expanded to include topics including modal analysis, digital image correlation, Split Hopkinson pressure bar, Residual stress, and biomaterials. Technical Divisions The society comprises seventeen technical divisions that program sessions at either the SEM Annual Conference or IMAC Conference, and develop content for publications: * Applied Photoelasticity * Biological Systems and Materials * Dynamics of Civil Structures * ...

Metal Foil Resistor
A metal (from Greek μέταλλον ''métallon'', "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the ''metallic bond'' between the atoms or molecules of the metal. A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. In physics, a metal is generally regarded as any substance capable of conducting electricity at a temperature of absolute zero. Many elements and compounds that are not normally classified as metals become metallic under high pressures. For example, the nonmetal iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Equally, some materials regarded as metals ...

Optical Coatings
An optical coating is one or more thin layers of material deposited on an optical component such as a lens, prism or mirror, which alters the way in which the optic reflects and transmits light. These coatings have become a key technology in the field of optics. One type of optical coating is an anti-reflective coating, which reduces unwanted reflections from surfaces, and is commonly used on spectacle and camera lenses. Another type is the high-reflector coating, which can be used to produce mirrors that reflect greater than 99.99% of the light that falls on them. More complex optical coatings exhibit high reflection over some range of wavelengths, and anti-reflection over another range, allowing the production of dichroic thin-film filters. Types of coating The simplest optical coatings are thin layers of metals, such as aluminium, which are deposited on glass substrates to make mirror surfaces, a process known as silvering. The metal used determines the reflection characte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Gibbons Tatnall
Francis Gibbons Tatnall (8 March 1896 – December 1981) was an American engineer and entrepreneur. He went by Frank and was born to William Francis Tatnall and Lillian Harriett Tatnall (born Runcie). Tatnall worked at Vishay Intertechnology and has been referred to as the spiritual father of strain gages. Education Tatnall graduated from the University of Pennsylvania with a Mechanical Engineering degree. Research and career Tatnall worked for the Baldwin-Southwark Corporation, a subsidiary of the Baldwin Locomotive Works, selling test equipment. During that stage of his career he traveled extensively getting to know everyone in the testing business and got to know many inventors developing new strain gauge technologies. He helped many of these inventors set up businesses, which he took financial stakes in, and arranged to sell the devices through Baldwin-Southwark. In 1951 Baldwin Locomotive Works merged with the Lima-Hamilton Corporation to form the Baldwin-Lima-Hami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trigonometry
Trigonometry () is a branch of mathematics that studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known tables of values for trigonometric ratios (also called trigonometric functions) such as sine. Throughout history, trigonometry has been applied in areas such as geodesy, surveying, celestial mechanics, and navigation. Trigonometry is known for its many identities. These trigonometric identities are commonly used for rewriting trigonometrical expressions with the aim to simplify an expression, to find a more useful form of an expression, or to solve an equation. History Sumerian astronomers studied angle measure, using a division of circles into 360 degrees. They, and later the Babylonians, studied the ratios of the sides of ...
