He served in the United States Navy in World War II as a second lieutenant. As a graduate student under Edward M. Purcell, he was the first to detect the galactic 21-cm hydrogen line. Biography Ewen was born on March 5, 1922, in Chicopee, Massachusetts, son of S. Arthur Ewen and Ruth F. Fay. After an education at the Technical High School in Springfield, Massachusetts, he matriculated at Amherst College, studying undergraduate mathematics and astronomy, and was awarded a B.A. in 1943. With World War II underway, he joined the Navy. Initially, he taught celestial navigation at Amherst as part of a pilot training program.

Green Bank Telescope
The Robert C. Byrd Green Bank Telescope (GBT) in Green Bank, West Virginia, US is the world's largest fully steerable radio telescope, surpassing the Effelsberg 100-m Radio Telescope in Germany. The Green Bank site was part of the National Radio Astronomy Observatory (NRAO) until September 30, 2016. Since October 1, 2016, the telescope has been operated by the independent Green Bank Observatory. The telescope's name honors the late Senator Robert C. Byrd who represented West Virginia and who pushed the funding of the telescope through Congress. The Green Bank Telescope operates at meter to millimeter wavelengths. Its 100-meter diameter collecting area, unblocked aperture, and good surface accuracy provide superb sensitivity across the telescope's full 0.1–116 GHz operating range. The GBT is fully steerable, and 85 percent of the local celestial hemisphere is accessible. It is used for astronomy about 6500 hours every year, with 2000–3000 hours per year going to high ...

Bart Bok
Bartholomeus Jan "Bart" Bok (April 28, 1906 – August 5, 1983) was a Dutch-American astronomer, teacher, and lecturer. He is best known for his work on the structure and evolution of the Milky Way galaxy, and for the discovery of Bok globules, which are small, densely dark clouds of interstellar gas and dust that can be seen silhouetted against brighter backgrounds. Bok suggested that these globules may be in the process of contracting, before forming into stars. Bok married fellow astronomer Priscilla Fairfield Bok, Priscilla Fairfield in 1929, and for the remainder of their lives, the two collaborated so closely on their astronomical work that the Royal Astronomical Society said "from that point on it is difficult and pointless to separate his achievements from hers". The Boks displayed such great mutual enthusiasm for explaining astronomy to the public that ''The Boston Globe'' described them in 1936 as "salesmen of the Milky Way". They worked together on research and co-autho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korean War
The Korean War (25 June 1950 – 27 July 1953) was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea was supported by China and the Soviet Union, while South Korea was supported by the United Nations Command (UNC) led by the United States. The conflict was one of the first major proxy wars of the Cold War. Fighting ended in 1953 with an armistice but no peace treaty, leading to the ongoing Korean conflict. After the end of World War II in 1945, Korea, which had been a Korea under Japanese rule, Japanese colony for 35 years, was Division of Korea, divided by the Soviet Union and the United States into two occupation zones at the 38th parallel north, 38th parallel, with plans for a future independent state. Due to political disagreements and influence from their backers, the zones formed their governments in 1948. North Korea was led by Kim Il S ...

Master Of Business Administration
A Master of Business Administration (MBA) is a professional degree focused on business administration. The core courses in an MBA program cover various areas of business administration; elective courses may allow further study in a particular area but an MBA is normally intended to be a general program. It originated in the United States in the early 20th century when the country industrialized and companies sought scientific management. MBA programs in the United States typically require completing about forty to sixty semester credit hours, much higher than the thirty semester credit hours typically required for other US master's degrees that cover some of the same material. The UK-based Association of MBAs accreditation requires "the equivalent of at least 1,800 hours of learning effort", equivalent to 45 US semester credit hours or 90 European ECTS credits, the same as a standard UK master's degree. Accreditation bodies for business schools and MBA programs ensure cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Horn Antenna
A horn antenna or microwave horn is an antenna (radio), antenna that consists of a flaring metal waveguide shaped like a horn (acoustic), horn to direct radio waves in a beam. Horns are widely used as antennas at Ultrahigh frequency, UHF and microwave frequencies, above 300 MHz. They are used as Antenna feed, feed antennas (called feed horns) for larger antenna structures such as parabolic antennas, as standard calibration antennas to measure the Antenna gain, gain of other antennas, and as directive antennas for such devices as radar guns, Sliding door operator, automatic door openers, and microwave radiometers. Their advantages are moderate directivity, broad Bandwidth (signal processing), bandwidth, low losses, and simple construction and adjustment. One of the first horn antennas was constructed in 1897 by Bengali-Indian radio researcher Jagadish Chandra Bose in his pioneering experiments with microwaves. reprinted in The modern horn antenna was invented indepe ...

Spectrometer
A spectrometer () is a scientific instrument used to separate and measure Spectrum, spectral components of a physical phenomenon. Spectrometer is a broad term often used to describe instruments that measure a continuous variable of a phenomenon where the spectral components are somehow mixed. In visible light a spectrometer can separate white light and measure individual narrow bands of color, called a spectrum. A mass spectrometer measures the spectrum of the masses of the atoms or molecules present in a gas. The first spectrometers were used to split light into an array of separate colors. Spectrometers were History_of_spectroscopy, developed in early studies of physics, astronomy, and chemistry. The capability of spectroscopy to determine Analytical_chemistry#Spectroscopy, chemical composition drove its advancement and continues to be one of its primary uses.
