Sir J.J.THOMSOM is to physics what electron is to an atom. He charged the world of physics with his discoveries and gave momentum to atomic physics. Physics is what today because of this British scientist who is regarded as the greatest experimental physicists of this century. A bookseller’s son‚ Thomsom studied at the Owens College and later at the Manchester University. He wanted to become an engineer‚ but his father’s death in 1872 forced him to study Mathematics‚ Physics and Chemistry as he

Is a Vegetarian Diet an Effective Choice for Weight Loss or Weight Control? In a study completed in 2003‚ it was found that approximately 4% of Canadians follow a vegetarian diet (“American Dietetic Association‚” 2003). This type of diet concentrates on the consumption of plants for food. The most common type is the lacto-ovo vegetarian diet‚ which restricts the intake of meat‚ poultry and fish‚ but allows the intake of eggs and dairy products (Vegetarian Diet‚ 2009). Many people become vegetarians

Integrated Physics and Chemistry – Unit 2: The Structure of Matter Experiment: Atomic Structure In this experiment‚ you will have a chance to test the hypothesis that Ernest Rutherford used when determining the size of the nucleus. In his "gold foil experiment‚" Rutherford shot alpha particles at gold atoms. Once he realized that the alpha particles were hitting a concentrated positive mass‚ he developed the nuclear model of the atom. Next‚ he set out to determine the relative size of the nucleus

Introduction: My aim is to investigate the relationship between weights and heights of mammals and amphibians. My main hypothesis is: heavier an animal the taller it will be. Sub-hypothesis: I believe there will be a stronger correlation between height and weight for mammals. I also believe that on average mammals are going to weigh more and be taller than amphibians. My plan is to collect data from many sources which will make my results more reliable. The data used for my investigation has been

Dalton was the first scientist to help contribute to the atomic theory. He based his thought process off of Democritus‚ an ancient Greek philosopher‚ who stated that at one point you will not be able to break down matter anymore‚ he called this basic building block an atom (meaning not divisible). Democritus believed that everything around us such as metal‚ water‚ and wood were atoms‚ but Dalton believed and proved that it could be more basic than that. He started thinking of compounds such as water

Of all of the many scientists who played a major role in the formation of the atomic theory‚ it is believed that Dalton‚ Rutherford‚ Thompson‚ Bohr‚ and Planck are the five most influential. The research of this theory has gone on for many years and each and every one of them have brought us closer to our current understanding of the atom today. Each one of them played a special role in the development process of the atom and most importantly‚ they all reflected on one another. Many influential scientists

underneath a baggy sweater and a thick pair of tummy tucking jeans. However‚ if you go with that idea for too long‚ by the time spring comes around you would have put on so much weight that you will not want to get rid of the baggy sweaters or the warm baggy sweat pants. And believe me‚ it’s much harder taking off that holiday weight than it was putting it on. The best trick I have learned over the years is to put on a bikini every week and see how my body looks. If I am okay with how things look‚ then

The Weight of The Things They Carried Tim O’Brien makes a very big deal out of the concept of “truth” throughout his novel The Things They Carried; such a big deal‚ in fact‚ that over the course of his work he continually redefines and even contradicts himself as to what “truth” really is. In the chapter entitled “How to Tell A True War Story”‚ O’Brien offers a multitude of criteria that supposedly defines what does and does not make a true war story. O’Brien offers the first commandment for
