- 241: The Problem Of Personal Identi
- ... another concept explained by Parry in his essay. He uses an example of if he had the same immaterial thing thinking in him, as Socrates did, along with being made up of the same material atoms as Socrates. But in neither case, could Parry say that he is Socrates. Parry then goes on to say that, it is not the immaterial thinking things that are important, but the sameness of conscious ...
- 242: Rodin's "The Kiss"
- ... ability of Rodin. X-ray fluorescence qualitatively analyzes the elements that exist in objects containing inorganic compounds. X-rays are emitted on to the object, which eject electrons from the inner orbital shells of the atoms. Radiation is then emitted when electrons in higher energy orbitals drop to fill a hole in a lower level. The levels of radiation determine which materials are present, because each material has a characteristic level ...
- 243: Atomic Bomb 2
- ... then the explosion goes in creating a even bigger force. This theory applies to Plutonium. Implosion occurs causing a chain reaction which in return causes an outwards explosion. If an inwards explosion occurred the Plutonium atoms would split apart creating the biggest explosion known to man. The problem was now creating an inward explosion. By this time, turmoil started to arise inside the camp. Many scientists began complaining about the drastic ...
- 244: Amazing Quran
- ... Muhammed's Prophethood, there was a well-known theory of atomism advanced by the Greek philosopher, Democritus. He and the people who came after him assumed that matter consists of tiny, indestructible, indivisible particles called atoms. The Arabs too, used to deal in the same concept; in fact, the Arabic word dharrah commonly referred to the smallest particle known to man. Now, modern science has discovered that this smallest unit of ...
- 245: Our Free Will
- ... as well as the position at that instant of all things of which the universe consists, would be able to comprehend the motions of the largest bodies in the universe and those of the smallest atoms in a single formula - provided that it was sufficiently powerful to submit all these data analysis. To it nothing would be uncertain and the future would be present to its eyes as much as the ...
- 246: Biography of John Dalton
- ... the first to prove that rain is precipitated by a decrease in temperature, not by a change in atmospheric pressure. Dalton's most important contribution to science was his theory that matter is composed of atoms of differing weights that combine in simple ratios by weight In 1808 Dalton published a book called A New System of Chemical Philosophy, in which he listed the atomic weights of a number of known ...
- 247: Biography of Ernest Rutherford
- ... in radioactivity in 1908. With the help of 15 research students, Rutherford was carrying out research on the nature of alpha particles. This research led him to believe that alpha particles were in fact Helium atoms. In 1908 Rutherford peformed a simple experiment involving the radioactive gas radon which decays by emitting alpha particles. The gas was placed within a glass container which also contained an evacuated glass tube containing electrodes ...
- 248: Marie Curie
- ... Marie knew this might happen, but she had hoped that it wouldn't. Some good did come out of Marie's research; for example nuclear reactors use the heat produced by the change of the atoms to make electricity. Canada has many of these reactor s, better known as CANDU reactors. The most well known field that Marie Curie's research has helped is in the field of medicine. Its primary ...
- 249: French Nuclear Testing
- ... bomb on Hiroshima was 15 kilotons. New Japanese research shows that bomb radiation increases risk of long term cancer. Radiation causes ionization in the molecules of living cells. The ions formed can react with the atoms in the cell causing damage. Cells that are changed permanently may produce abnormal cells when they divide, perhaps become cancerous. Not only are there health risks, but the French economy just lost a contract to ...
- 250: Lung Cancer 3
- ... Travels through the body and kills the cancer cells. Chemo. is also used to kill cancer cells that have spread from the primary tumour. Radiation Radiation uses high-energy x-rays or gamma rays (radioactive atoms) to kill cancer cells and shrink tumours. Radiation can come externally( from a machine outside the body) or internally from radioactive iodine which is injected into the body. Radiation stops the cells from dividing so ...
