Ernest Rutherford. Ernest Rutherford, 1st Baron Rutherford of Nelson, OM, FRS, HonFRSE [7] (30 August 1871 – 19 October 1937), was a New Zealand physicist who was a pioneering researcher in both atomic and nuclear physics. He has been described as "the father of nuclear physics", [8] and "the greatest experimentalist since Michael Faraday ". [9]
Later in the war, the Norden was combined with other systems to widen the conditions for successful bombing. Notable among these was the radar system called the H2X (Mickey), which were used directly with the Norden bombsight. The radar proved most accurate in coastal regions, as the water surface and the coastline produced a distinctive radar ...
Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, [1] visible light, radio frequency (RF) spectrum, and audio, all collectively known as stealth technology. [2] The F-117 Nighthawk was the first operational aircraft explicitly designed around stealth technology ...
J. Robert Oppenheimer. J. Robert Oppenheimer (born Julius Robert Oppenheimer; / ˈɒpənhaɪmər / OP-ən-hy-mər; April 22, 1904 – February 18, 1967) was an American theoretical physicist who served as the director of the Manhattan Project 's Los Alamos Laboratory during World War II. He is often called the "father of the atomic bomb " for ...
A BGM-109 Tomahawk flying in November 2002. A cruise missile is an unmanned self-propelled guided vehicle that sustains flight through aerodynamic lift for most of its flight path and whose primary mission is to place an ordnance or special payload on a target. [1] Cruise missiles are designed to deliver a large warhead over long distances with ...
The Rutherford model was devised by Ernest Rutherford to describe an atom. Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson 's plum pudding model of the atom was incorrect. Rutherford's new model [1] for the atom, based on the experimental results, contained new ...
William Alfred Higinbotham[1][2][3] (October 22, 1910 – November 10, 1994) was an American physicist. A member of the team that developed the first nuclear bomb, he later became a leader in the nonproliferation movement. He also has a place in the history of video games for his 1958 creation of Tennis for Two, the first interactive analog ...
With further advances, it became practical to generate pulses having a width on the same order as the period of the RF carrier (T = 1/f). This is now generally called impulse radar. The first significant application of this technology was in ground-penetrating radar (GPR). Developed in the 1970s, GPR is now used for structural foundation ...
