Edward Bennett (physicist)
Edward Bennett was an American physicist, known from his early involvements in wireless transmission. He obtained a Ph.D. in electrical engineering at the University of Pittsburgh (then known as the Western University of Pennsylvania) in 1897.Tapan Sarkar, ''History of Wireless'', p. 369. Wiley, 2006 The work was on spark-gap transmitters, jointly with William Bradshaw and supervised by Reginald Fessenden. Working at the University of Wisconsin–Madison, he achieved fame in the history of broadcasting from his work with Dr. Earle M. Terry that led to the first transmissions of the WHA (AM) radio station (1914). He later headed the electrical engineering department.

Electrical Engineering
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control, and electrical m ...

University Of Wisconsin–Madison Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Year Of Death Missing
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electrodynamics
In physics, electromagnetism is an interaction that occurs between particles with electric charge. It is the second-strongest of the four fundamental interactions, after the strong force, and it is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electricity and magnetism, two distinct but closely intertwined phenomena. In essence, electric forces occur between any two charged particles, causing an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs exclusively between ''moving'' charged particles. These two effects combine to create electromagnetic fields in the vicinity of charge particles, which can exert influence on other particles via the Lorentz force. At high energy, the weak force and electromagnetic force are unified as a single electroweak force. The electromagnetic force is responsible for many o ...

WHA (AM)
WHA (970 AM) is a non-commercial radio station, licensed since 1922 to the University of Wisconsin and located in Madison, Wisconsin. It serves as the flagship for the Wisconsin Public Radio talk-based "Ideas Network". WHA's programming is also broadcast by two low-powered FM translators, and by WERN FM's HD3 digital subchannel. The station airs a schedule of news and talk programs from Wisconsin Public Radio, NPR, American Public Media, Public Radio International, the Canadian Broadcasting Corporation and the BBC. The same call letters are used by WHA-TV in Madison, the flagship station for PBS Wisconsin. Broadcast frequencies WHA transmits on 970 AM from a 258-foot tower at Silver Spring Farm within the University of Wisconsin–Madison Arboretum. It operates at 5,000 watts during the day. Although WHA's tower is relatively short by modern broadcasting standards, its transmitter power and Wisconsin's flat land (with near-perfect ground conductivity) gives it a daytime cove ...
