Ernest Rutherford Born on August 30th‚ 1871 in New Zealand‚ Ernest Rutherford accomplished to be one of many successful chemists throughout the world in the 19th and the 20th centuries. With his brilliant experiments he explained the puzzling problem of radioactivity and the sudden breakdown of atoms. In addition‚ he determined the structure of the atom and was first to ever split it. Rutherford’s great mind triggered innovations of new technology such as the smoke detector that saves many

1 Earth Earth ‚ our home planet‚ is beautiful blue and white ball when seen from space. Science is the study of the Earth and its neighbors in space. It is an exciting science with many interesting and practical applications. Some Earth scientists use their knowledge of the Earth to locate and develop energy and mineral resources.

HlavacEnglish IV Honors 18 January 2013 Why We Should Continue To Explore Space Space exploration is an important aspect of our nation’s research into the future of mankind. The money spent on space exploration is a meaningful investment. The United States’ government should continue to spend money on space exploration. The space program in the United States counts for a small part of our yearly budget. The average percent spent on the program is between 0.7% and 0.8%. This percent is tiny compared to the

creation of the first Atomic Theory: Democritus‚ Antoine Lavoisier‚ Joseph Proust‚ and John Dalton. Dalton took the information that he had taken from the three scientists prior to him and put everything into one theory. The Atomic Theory is the most well-known and accurate theory we know right now. Later on in history‚ more scientists came to contribute to the understanding of the Atomic Structure. These scientists included: Sir J.J. Thomson‚ Robert Millikan‚ Ernest Rutherford‚ Niels Bohr‚

Book Overview The book Orbiting the Giant Hairball was written by Gordon MacKenzie in 1996. Originally self-published the book became a business "cult classic". Gordon was an employee of Hallmark Cards for 30 years‚ where he inspired his colleagues to slip the bonds of Corporate Normalcy and rise to “orbit” - to a mode of dreaming‚ daring‚ and doing above and beyond the rubber-stamp confines of the administrative mind-set. As a testament to his career and the level of creativity he maintained

Introduction Nowadays‚ Global warming is an incontrovertible fact‚ which proves that our planet and its climate are in trouble. Well global warming is a term that denotes a slow warming of the earth’s regular temperature. It was also named exclusively man-made effects‚ in particular carbon dioxide. Carbon dioxide has largely increased during the past forty years‚ and scientists concluded that the average earth temperature has increased solely based on man-made activities such

Planet Venus and Earth are often called twins because they are similar in size‚ mass‚ density‚ composition and gravity. However‚ the similarities end there. [Photos of Venus‚ the Mysterious Planet Next Door] Venus is the hottest world in the solar system. Although Venus is not the planet closest to the sun‚ its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms up the Earth. As a result‚ temperatures on Venus reach 870 degrees F (465 degrees C)‚ more than hot

The History of Atomic Theory Atomos: Not to Be Cut The atomic model has changed throughout the centuries starting in 400 BC‚ when it looked like a billiard ball. Democritus: 400 BC The question: Can matter be divided into smaller particles? Or can it be infinitely divided? Matter can be divided into the smallest piece‚he named it “atomos”: not to be cut. Said that atoms were small‚ hard particles that were all made of the same material but were different shapes and sizes. Atoms were

Mintzberg defined organisational structure as " the sum total of the ways in which it divides its labour into distinct tasks and then achieves coordination among them ". Each configuration contains six components: characteristics 1. operating core : the people directly related to the
