John Trowbridge (physicist)
John Trowbridge (August 5, 1843 – February 18, 1923) was an American physicist, noted for his research into electricity and magnetism, and for his innovations in scientific education. Early life Born into a long-established New England family, John Trowbridge could trace his roots in Massachusetts and Connecticut back to the early seventeenth century. His father, John Howe Trowbridge, was a graduate of Harvard Medical School, but did not pursue a professional career, having inherited a sufficient fortune to finance a life of ease. Evidently this state of affairs did not last, however, and the younger Trowbridge would later recount that he was obliged to support himself in youth by monetising his talents as a painter. Also an accomplished pianist and writer, a career in arts and letters seemingly beckoned, but pragmatic considerations led him ultimately to pursuit of the sciences. Academic career Trowbridge studied physics at the Lawrence Scientific School of Harvard Univers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

X-ray
An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz ( to ) and energies in the range 145 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it on November 8, 1895. He named it ''X-radiation'' to signify an unknown type of radiation.Novelline, Robert (1997). ''Squire's Fundamentals of Radiology''. Harvard University Press. 5th edition. . Spellings of ''X-ray(s)'' in English include the variants ''x-ray(s)'', ''xray(s)'', and ''X ray(s)''. The most familiar use of X-rays is checking for fractures (broken bones), but X-rays are also used in other ways. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical Spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, ultraviolet, X-ray, infrared and radio waves that radiate from stars and other celestial objects. A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance and luminosity. Spectroscopy can show the velocity of motion towards or away from the observer by measuring the Doppler shift. Spectroscopy is also used to study the physical properties of many other types of celestial objects such as planets, nebulae, galaxies, and active galactic nuclei. Background Astronomical spectroscopy is used to measure three major bands of radiation in the electromagnetic spectrum: visible light, radio waves, and X-rays. While all spectroscopy looks at specific bands of the spectrum, different methods are required to acquire the signal depending on the frequenc ...

Rumford Chair Of Physics
The Rumford Chair of Physics (originally the Rumford Chair and Lectureship on the Application of Science to the Useful Arts) is an endowed professorship established at Harvard University in 1816 under the will of Benjamin Thompson, Count Rumford. Endowment Specifically, an initial annuity of $1000 (with reversion of certain further substantial annuities) was bequeathed “for the purpose of founding a new institution and professorship, in order to teach by regular courses of academical and public lectures, accompanied with proper experiments, the utility of the physical and mathematical sciences for the improvement of the useful arts, and for the extension of the industry, prosperity, happiness, and well-being of society.” The centrality of “useful” knowledge, in contradistinction to the classical tradition then dominant at Harvard, was further emphasised by a stipulation that the professorship was to be held outside of the philosophy department.
