Rutherford

Ernest Rutherford (Nelson, Nueva Zelanda, 1871 - Londres, 1937) Físico y químico británico. Tras licenciarse, en 1893, en Christchurch (Nueva Zelanda), Ernest Rutherford se trasladó a la Universidad de Cambridge (1895) para trabajar como ayudante de Ernest Rutherford Por sus trabajos en el campo de la física atómica, Ernest Rutherford está considerado como uno de los padres de esta disciplina. Investigó sobre la detección de las radiaciones electromagnéticas y sobre la ionización del aire producida por los rayos X, estudió las emisiones radioactivas descubiertas por En 1911 describió un nuevo modelo atómico (modelo atómico de Rutherford), que posteriormente sería perfeccionado por Durante la Muy poco después de su descubrimiento se precisaron las características de las transmutaciones y se comprobó que la energía cinética de los protones emitidos en el proceso podía ser mayor que la de las partículas incidentes, de modo que la energía interna del núcleo tenía que intervenir la transmutación. En 1923, tras fotografiar cerca de 400.000 trayectorias de partículas con la ayuda de una cámara de burbujas (cámara de Wilson), Rutherford recibió el Premio Nobel de Química de 1908 en reconocimiento a sus investigaciones relativas a la desintegración de los elementos. Entre otras distinciones, fue elegido miembro (1903) y presidente (1925-1930) de la Royal Society de Londres, y se le concedieron los títulos de sir (1914) y de barón Rutherford of Nelson (1931); el elemento 104 de la C...

The Rutherford atomic model was correct in that the atom is mostly empty space. Most of the mass is in thenucleus, and the nucleus is positively charged.

(Rutherford famously said later, “It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you.”) Only a positively charged and relatively heavy target particle, such as the proposed nucleus, could account for such strong repulsion.

Scott Broden, Murfreesboro Daily News Journal • Rutherford County Commission set to vote on tax and budget plans June 26 • County plans 6 stations for firefighters and ambulances crews • Almaville Volunteer Fire Department not part of current plans for full-time firefighters • Homes appraised at median value would pay over $200 more in taxes A counter to Rutherford County Mayor Joe Carr's The "fire tax" recommended by Trey Gooch, a member of Gooch, however, faced opposition from the majority of the commission's seven-member Budget, Finance & Investment Committee. The committee members, including Commissioner Wayne Irvin, suggested the fire tax be studied to determine if one should be established in future years rather than approved for the next fiscal year that starts July 1. "I'm going to keep an open mind, but I don't like tax increases," Irvin said. The budget committee will be holding a public hearing on the mayor's proposed tax hike and budget plans at 7 p.m. Tuesday, June 13, at the Rutherford County Courthouse in the center of Murfreesboro's downtown Square. The full 21-member county commission will consider the tax and budget plans at 9 a.m. June 26 at the Rutherford County Courthouse in the center of Murfreesboro's downtown Square. County gains new leaders: Homes appraised at median value would pay over $200 more in taxes Gooch suggested the property tax rate of $1.6162 per $100 of assessed value go up by 31 cents for only those living in unincorporated areas, whi...

Leasing has officially launched for the second residential building at the Mayor Frank Nunziato and fellow municipal officials joined Vango Development last week for a ceremonial ribbon-cutting to officially open the collection of 60 apartments and amenities located at 118 Park Ave. Well-appointed studios, one- and two-bedroom homes currently begin from $2,370, with immediate occupancy available. “The completion of the Parker is an excellent addition to our downtown,” Nunziato said. “I’d like to thank everyone who worked on this project to make it a great fit for Rutherford and look forward to the future as its residents become patrons of our local businesses.” The Parker 118 joins its sister property at 106 Park Ave., which debuted in 2019 with 52 residences and 5,000 square feet of retail space that houses Steven’s Café and Song’E Napule, the popular pizzeria and trattoria that made history last month as the first Rutherford business to obtain a liquor license since the late 1800s. The new building bolsters the vibrant streetscape with an additional 3,000 square feet of retail space that will include the Salad House and a high-end salon, enriching the conveniences and services for both residents of the Parker and the broader community. “We thank Mayor Nunziato for joining us today to celebrate the opening of the Parker 118 and appreciate the continued confidence of Rutherford’s municipal administration in our efforts to enhance the downtown and contribute to the resident...

Michael Karas, NorthJersey On the surface, it seemed like a simple proposal for the borough of Rutherford. Elm Street would be renamed "Marshall Place" for The idea was endorsed in a 5-2 vote last September by the Rutherford Historic Preservation Committee, sending the proposal on to the mayor and council for consideration. Yet months later, the renaming has gone nowhere, said the former borough historian, Rod Leith, who first proposed the idea. The mayor is not talking, the Historic Preservation Committee has been disbanded and the propriety of honoring Williams' legacy has been called into question by vague, as yet unsubstantiated talk of racism. The disagreement has raised sensitive questions of how to treat such accusations, which residents are deserving of being honored in their hometown and who determines how to acknowledge the history and contributions of African Americans in a town where they make up only 2% of the population. "We felt that since Marshall lived on that street and maintained his chicken coops there, and his son Milton was a World War I veteran from Rutherford, they deserved the tribute," Leith said. Leith said the hold on the proposal happened after another lifelong resident, Bill Galloway, objected to the renaming at Rutherford Historic Preservation Committee meetings in September and October. Leith, a former reporter at The Record, said Galloway referred to Williams as a "racist" at the October meeting. After Galloway made his concerns known to Ru...

Ernest Rutherford’s most famous experiment is the gold foil experiment. A beam of alpha particles was aimed at a piece of gold foil. Most alpha particles passed through the foil, but a few were scattered backward.
