Edward E. Simmons
Edward E. Simmons Jr. (1911 in Los Angeles, California – May 18, 2004, in Pasadena, California) was an electrical engineer and the inventor of the bonded wire resistance strain gauge. Simmons attended the California Institute of Technology, where he received a B.S. in 1934 and an M.S. in 1936. He continued to work for the Institute under Assistant Professor Donald Clark. In 1938, Simmons invented the strain gauge. Caltech claimed the patent on the strain gauge, but Simmons took his case to the Supreme Court of California, and won patent rights in 1949. The Franklin Institute awarded Simmons the Edward Longstreth Medal The Franklin Institute is a science museum and the center of science education and research in Philadelphia, Pennsylvania.

Electrical Engineering
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control, and electrical m ...

Strain Gauge
A strain gauge (also spelled strain gage) is a device used to measure strain on an object. Invented by Edward E. Simmons and Arthur C. Ruge in 1938, the most common type of strain gauge consists of an insulating flexible backing which supports a metallic foil pattern. The gauge is attached to the object by a suitable adhesive, such as cyanoacrylate. As the object is deformed, the foil is deformed, causing its electrical resistance to change. This resistance change, usually measured using a Wheatstone bridge, is related to the strain by the quantity known as the gauge factor. History Edward E. Simmons and Professor Arthur C. Ruge independently invented the strain gauge. Simmons was involved in a research project by Dätwyler and Clark at Caltech between 1936 and 1938. They researched the stress-strain behavior of metals under shock loads. Simmon came up with an original way to measure the force introduced into the sample by equipping a dynamometer with fine resistance wires ...

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. The institute is also occasionally referred to as "CIT", most notably in its alma mater, but this is uncommon. is a private research university in Pasadena, California. Caltech is ranked among the best and most selective academic institutions in the world, and with an enrollment of approximately 2400 students (acceptance rate of only 5.7%), it is one of the world's most selective universities. The university is known for its strength in science and engineering, and is among a small group of institutes of technology in the United States which is primarily devoted to the instruction of pure and applied sciences. The institution was founded as a preparatory and vocational school by Amos G. Throop in 1891 and began attracting influential scientists such as George Ellery H ...

Supreme Court Of California
The Supreme Court of California is the highest and final court of appeals in the courts of the U.S. state of California. It is headquartered in San Francisco at the Earl Warren Building, but it regularly holds sessions in Los Angeles and Sacramento. Its decisions are binding on all other California state courts. Since 1850, the court has issued many influential decisions in a variety of areas including torts, property, civil and constitutional rights, and criminal law. Composition Under the original 1849 California Constitution, the Court started with a chief justice and two associate justices. The Court was expanded to five justices in 1862. Under the current 1879 constitution, the Court expanded to six associate justices and one chief justice, for the current total of seven. The justices are appointed by the Governor of California and are subject to retention elections. According to the California Constitution, to be considered for appointment, as with any California ju ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franklin Institute
The Franklin Institute is a science museum and the center of science education and research in Philadelphia, Pennsylvania. It is named after the American scientist and statesman Benjamin Franklin. It houses the Benjamin Franklin National Memorial. Founded in 1824, the Franklin Institute is one of the oldest centers of science education and development in the United States. Its chief astronomer is Derrick Pitts. History On February 5, 1824, Samuel Vaughan Merrick and William H. Keating founded the Franklin Institute of the State of Pennsylvania for the Promotion of the Mechanic Arts. Begun in 1825, the institute was an important force in the professionalization of American science and technology through the nineteenth century, beginning with early investigations into steam engines and water power. In addition to conducting scientific inquiry, it fostered research and education by running schools, publishing the influential ''Journal of The Franklin Institute'', sponsoring e ...

Tutu (clothing)
A tutu is a dress worn as a costume in a classical ballet performance, often with attached bodice. It may be made of tarlatan, muslin, silk, tulle, gauze, or nylon. Modern tutus have two basic types: the Romantic tutu is soft and bell-shaped, reaching the calf or ankle; the Classical tutu is short and stiff, projecting horizontally from the waist and hip. Etymology The word tutu can refer to only the skirt part of the costume. The bodice and tutu make up what is usually the entire costume, but which is called the tutu (by synecdoche, wherein the part – the skirt – can embody the whole). The derivation of the word '' tutu'' is unknown. The word was not recorded anywhere until 1881. One theory is that it is simply derived from the word ''tulle'' (one of the materials from which it is made). A second theory is that the word comes from the slang of French children that refers to the buttocks (''cul''). During that era, the ''abonnés'' (rich male subscribers at the Paris Opera ...

Find A Grave
Find a Grave is a website that allows the public to search and add to an online database of cemetery records. It is owned by Ancestry.com. Its stated mission is "to help people from all over the world work together to find, record and present final disposition information as a virtual cemetery experience." Volunteers can create memorials, upload photos of grave markers or deceased persons, transcribe photos of headstones, and more. , the site claimed more than 210 million memorials. History The site was created in 1995 by Salt Lake City resident Jim Tipton (born in Alma, Michigan) to support his hobby of visiting the burial sites of celebrities. He later added an online forum.

Robert Andrews Millikan
Robert Andrews Millikan (March 22, 1868 – December 19, 1953) was an American experimental physicist honored with the Nobel Prize for Physics in 1923 for the measurement of the elementary electric charge and for his work on the photoelectric effect. Millikan graduated from Oberlin College in 1891 and obtained his doctorate at Columbia University in 1895. In 1896 he became an assistant at the University of Chicago, where he became a full professor in 1910. In 1909 Millikan began a series of experiments to determine the electric charge carried by a single electron. He began by measuring the course of charged water droplets in an electric field. The results suggested that the charge on the droplets is a multiple of the elementary electric charge, but the experiment was not accurate enough to be convincing. He obtained more precise results in 1910 with his famous oil-drop experiment in which he replaced water (which tended to evaporate too quickly) with oil. In 1914 Millikan took ...
