Calvin D. MacCracken
Calvin Dodd MacCracken (1919-1999) was an American inventor who made important contributions to energy storage technology and the construction of ice rinks. Early life MacCracken was born in Poughkeepsie, New York to Henry Noble MacCracken, a president of Vassar College and Marjorie Dodd MacCracken. Cal MacCracken entered Princeton University at age 16 and graduated in 1940. After briefly working with Thomas Edison's son he attended Massachusetts Institute of Technology, where he earned a degree in mechanical engineering. From college, MacCracken went to work at General Electric Corporation, where he designed the first combustion chamber and throttled the first jet engine.

American People
Americans are the citizens and nationals of the United States of America.; ; Although direct citizens and nationals make up the majority of Americans, many dual citizens, expatriates, and permanent residents could also legally claim American nationality. The United States is home to people of many racial and ethnic origins; consequently, American culture and law do not equate nationality with race or ethnicity, but with citizenship and an oath of permanent allegiance. Overview The majority of Americans or their ancestors immigrated to the United States or are descended from people who were brought as slaves within the past five centuries, with the exception of the Native American population and people from Hawaii, Puerto Rico, Guam, and the Philippine Islands, who became American through expansion of the country in the 19th century, additionally America expanded into American Samoa, the U.S. Virgin Islands and Northern Mariana Islands in the 20th century. * ...

People From Poughkeepsie, New York
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

New Jersey Inventors Hall Of Fame
The New Jersey Inventor's Hall of Fame was established in 1987 to honor individuals and corporations in New Jersey for their inventions. Award recipients are recognized at the annual Award Banquet Dinner. The New Jersey Inventors Hall of Fame operated from 1987 to 2002 at the New Jersey Institute of Technology, from 2003 to 2007 with support from the Research and Development Council of New Jersey.

Ice Skating Institute
The Ice Skating Institute (formerly the Ice Skating Institute of America) is a trade association for ice rinks, and also an international governing body for recreational figure skating. It was founded in 1959 to proliferate the building of permanent indoor ice rinks, which numbered fewer than 100 at the time, as well as to promote skating as a recreational activity. One of the founders was Michael Kirby. The ISI has developed a program of tests and competitions in all areas of figure skating, as well as limited areas of speed skating and ice hockey, from "Tot" levels to advanced tests that would provide interesting challenges even to Olympic medalists. The ISI operates its programs independently from the International Skating Union The International Skating Union (ISU) is the international governing body for competitive ice skating disciplines, including figure skating, synchronized skating, speed skating, and short track speed skating. It was founded in Scheveningen, N ..., ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squash (sport)
Squash is a racket-and- ball sport played by two or four players in a four-walled court with a small, hollow, rubber ball. The players alternate in striking the ball with their rackets onto the playable surfaces of the four walls of the court. The objective of the game is to hit the ball in such a way that the opponent is not able to play a valid return. There are about 20 million people who play squash regularly world-wide in over 185 countries. The governing body of Squash, the World Squash Federation (WSF), is recognized by the International Olympic Committee (IOC), but the sport is not part of the Olympic Games, despite a number of applications. Supporters continue to lobby for its incorporation in a future Olympic program. The Professional Squash Association (PSA) organizes the pro tour. History Squash has its origins in the older game of rackets which was played in London's prisons in the 19th century. Later, around 1830, boys at Harrow School noticed that a punctured ...

Pneumonia
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. The severity of the condition is variable. Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia. Risk factors for pneumonia include cystic fibrosis, chronic obstructive pulmonary disease (COPD), sickle cell disease, asthma, diabetes, heart failure, a history of smoking, a poor ability to cough (such as following a stroke), and a weak immune system. ...

Radiant Heat
Thermal radiation is electromagnetic radiation generated by the thermal motion of particles in matter. Thermal radiation is generated when heat from the movement of charges in the material (electrons and protons in common forms of matter) is converted to electromagnetic radiation. All matter with a temperature greater than absolute zero emits thermal radiation. At room temperature, most of the emission is in the infrared (IR) spectrum. Particle motion results in charge-acceleration or dipole oscillation which produces electromagnetic radiation. Infrared radiation emitted by animals (detectable with an infrared camera) and cosmic microwave background radiation are examples of thermal radiation. If a radiation object meets the physical characteristics of a black body in thermodynamic equilibrium, the radiation is called blackbody radiation. Planck's law describes the spectrum of blackbody radiation, which depends solely on the object's temperature. Wien's displacement la ...
