Ernest Rutherford was a New Zealand physicist and chemist who earned the title “Father of Nuclear Physics” after his discoveries of radioactive half-lives‚ differentiated between alpha and beta radiation‚ and proved that radioactivity involved the transmutation of one chemical element to another. He is also the recipient of the 1908 Nobel Prize in Chemistry "for his investigations into the disintegration of the elements‚ and the chemistry of radioactive substances". Ernest Rutherford was born

MINOR MEMBERS OF THE SOLAR SYSTEM ASTEROIDS Asteroids are small rocky bodies that have been likened to “flying mountains.” The largest‚ Ceres‚ is about 1000 kilometers in diameter‚ but most are only about 1 kilometer across. The smallest asteroids are assumed to be no larger than grains of sand. Most asteroids lie between the orbits of Mars and Jupiter. They have orbital periods of three to six years. Some asteroids have very eccentric orbits and travel very close to the sun‚ and a few larger

are 8 planets in our solar system; these are divided into two types‚ large gas giants (Jupiter‚ Saturn‚ Uranus and Neptune) and smaller rocky terrestrial planets (Mercury‚ Venus‚ Earth and Mars). The order from closest to the Sun outwards is; Mercury‚ Venus‚ Earth‚ Mars‚ Jupiter‚ Saturn‚ Uranus and finally Neptune. Until 2006 Pluto was also classed as a planet‚ however it is now classified as a dwarf planet (meeting the first two requirements of the definition but not the third). A planet is currently

____________________________________________ Solar Energy System Design The largest solar electric generating plant in the world produces a maximum of 354 megawatts (MW) of electricity and is located at Kramer Junction‚ California. This solar energy generating facility‚ shown below‚ produces electricity for the Southern California Edison power grid supplying the greater Los Angeles area. The authors ’ goal is to provide the necessary information to design such systems. The solar collectors concentrate sunlight

In the outer limits of our solar system there is a planet unlike any other‚ Pluto. Pluto was discovered in February of 1930 by an American astronomer‚ Clyde Tombaugh. It is the only planet to have been discovered by an American. All though we have known of the existence of Pluto for over thirty years now‚ there are still many mysteries surrounding this celestial body. Being the farthest planet has made it difficult to study Pluto‚ Adding to the obscurity of this strange planet is that the capability

Ernest lived a very interesting life. Author’s Background Born in New Zealand in 1871‚ he aspired to be great. At the age of 26 he moved to Canada and became Professor of Physics at McGill University in Montreal. He was awarded the Nobel Prize in Chemistry on December 10th‚ 1908. Rutherford

AQUA-MARIE Solar System Nebular Hypothesis. According to the nebular hypothesis‚ these clouds collapsed from some kind of turbulence that caused it to heat up and eventually turn into a star. My understanding of the origin and evolution of the solar system is still very limited. Development is made by pushing through the scientific process of hypothesis‚ prediction‚ measurement‚ theory‚ and hypothesis. However‚ there is still a lot of guesswork to be tested before we can really talk about

Our planet is in great danger. For the last one hundred or so years‚ the people of earth have wasted and misused the natural resources of earth. Several plans have been developed to stop the abuse of earth. Some of these plans I will discuss in this essay‚ many of which can be executed by any one. Environmental problems have become so complex that many individuals feel they can have no effect on them. Problems like oil spills‚ hazardous waste‚ loss of rain forests‚ endangered species‚ acid rain‚
