Floyd K. Richtmyer
Floyd Karker Richtmyer (October 12, 1881 – November 7, 1939) was a physicist and educator in the United States. Early life Richtmyer was born October 12, 1881, in the rural community of Cobleskill, New York. He studied with Perley Nutting at Cornell University; both were students of Edward L. Nichols. Richtmyer graduated with his A.B. in 1904 and Ph.D. in 1910. Career Richtmyer taught physics at Drexel University but returned to Cornell as an instructor in 1906, where he remained for the duration of his career. He became assistant professor of physics in 1911, full professor in 1918, and then dean of the graduate school in 1931. He also taught summer classes at the University of California, Berkeley, Stanford University, and Columbia University. When the ''Journal of the Optical Society of America'' (''JOSA'') began in 1917, Richtmyer wrote the very first article, on page 1 of volume 1, titled "Opportunities for Research." In 1918 and 1919, he served as OSA’s vic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Coronary Thrombosis
Coronary thrombosis is defined as the formation of a blood clot inside a blood vessel of the heart. This blood clot may then restrict blood flow within the heart, leading to heart tissue damage, or a myocardial infarction, also known as a heart attack. Coronary thrombosis is most commonly caused as a downstream effect of atherosclerosis, a buildup of cholesterol and fats in the artery walls. The smaller vessel diameter allows less blood to flow and facilitates progression to a myocardial infarction. Leading risk factors for coronary thrombosis are high low-density lipoprotein cholesterol, smoking, sedentary lifestyle, and hypertension. Symptoms of coronary thrombosis are not always evident at the start. Symptoms include chest pain, shortness of breath, and discomfort in the upper body. A coronary thrombosis is a medical emergency (life threatening) and requires emergency care at a hospital. Signs and symptoms A coronary thrombus is asymptomatic until it causes significant obs ...

Richtmyer Memorial Award
The Richtmyer Memorial Award is an award for physics education, named for physicist Floyd K. Richtmyer and given annually by the American Association of Physics Teachers. Its recipients include over 15 Nobel Prize winners. Establishment and award criteria Floyd T. Richtmyer (1881–1939) was one of the first presidents of the American Association of Physics Teachers and his work helped shape the development of physics in the United States. The Richtmyer Award was established in 1941, and is typically given to educators who have made outstanding contributions as teachers in their fields. It is awarded to those who have not only produced important current research in physics, but to those who have, by means of communication to both students and other educators, imparted information and motivation to participants in the field. The effective use of a teaching method in order to pass on information, and to stimulate interest in physics, is seen as being worthy of recognition in its ow ...

The AAPT became a founding member of the American In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
X-ray
An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays. Roughly, X-rays have a wavelength ranging from 10 Nanometre, nanometers to 10 Picometre, picometers, corresponding to frequency, frequencies in the range of 30 Hertz, petahertz to 30 Hertz, exahertz ( to ) and photon energies in the range of 100 electronvolt, eV to 100 keV, respectively. X-rays were discovered in 1895 in science, 1895 by the German scientist Wilhelm Röntgen, Wilhelm Conrad Röntgen, who named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . X-rays can penetrate many solid substances such as construction materials and living tissue, so X-ray radiography is widely used in medical diagnostics (e.g., checking for Bo ...
