- 101: Dwight D Eisenhower
- ... to help him win. He was able to serve two terms as President of the United States from January 20, 1953 to January 20, 1961. He saw the end of the Korean War, and promoted “Atoms for Peace” and dealt with several crisis in Lebanon, Suez, Berlin, and Hungary in Foreign affairs. He helped make Alaska and Hawaii become states. Throughout his presidency he was very concerned with civil rights issues ... Federal courts decision. He also ordered the complete desegregation of the armed forces. He wrote “ There must be no second class citizens in this country.” A program that eisenhower was quite proud of was his “Atoms for Peace” program which was the loan of American uranium to “have not” nations for peaceful purposes. In March 1961, President Eisenhower returned to active list of regular army with rank of General of the ...
- 102: Sir William Lawrence Bragg
- ... together to treat them mathematically and simplify their interpretation. Lawrence Bragg discovered that certain planes in a crystal reflect X rays, in accordance with the normal law of reflection. The distance between parallel planes of atoms determines the angle at which reflection can take place for a certain wavelength of the X rays. This relation, known as Bragg's law, permitted physicists to measure the wavelengths of the X rays. For crystals of simple structure, like salt, physicists could calculate the distances between the planes of atoms from previous data and use the results to find the wavelength of the X rays. These discoveries served as the foundation for further research. The Braggs decided to build upon initial findings by using X ...
- 103: Your Chemical World
- ... the father of chemistry is given to Dmitri Mendeleev, who not only formulated the periodic law but also created the periodic table of elements. Sir Joesph John Thomson then proposed the idea of protons in atoms, followed by Sir Ernest Rutherfords Nuclear theory with an atom proton. Eventually all the elements that we have today were discovered and put into place on the periodic table giving us today’s modern chemistry ... the father of chemistry is given to Dmitri Mendeleev, who not only formulated the periodic law but also created the periodic table of elements.

- 104: Free Will Vs. Determinism
- ... remains an anomaly in science. Almost every area of science is based on cause and effect, order, and a structured protocol of operation, but the Quantum Mechanics is different. All matter is made up of atoms, and all atoms are made up of electrons, neutrons, and protons. These in turn are made up of quarks. The movement of quarks, and the emission of photons as electrons skip shells seem to be totally random. If ...
- 105: Atomic Bomb 2
- ... science of physics had been undergoing a revolution for the past thirty-odd years. Scientists now had a clear picture of what the atomic world was like. They knew the structure and particle makeup of atoms, as well as how they behaved. During the 1930Õ³ it became apparent that there was a immense amount of energy that would be released atoms of Gioielli 2certain elements were split, or taken apart. Scientists began to realize that if harnessed, this energy could be something of a magnitude not before seen to human eyes. They also saw that this ...
- 106: Spoon River
- ... hard times. He compared people in Spoon River to navigators and sailors because they found with all their boasted wisdom how hard at the last it is to keep the soul from splitting into cellular atoms. He also says that seekers of earth's treasures are self-contained and harmonized even to the end. In this poem you are not told what Thomas does for a living, but it is implied ... blown about by erratic currents tumbling into air pockets, you Margaret Fuller Slacks, Petits, and Tennessee Claflin Shopes, you found... how hard at the last it is to keep the soul from splitting into cellular atoms." The quotes are metaphors of the people who are always changing their minds because of what other people say and end up doing something they regret so badly, they begin to fall apart emotionally and ...

- 108: Amedeo Avogadro (1776-1856)
- ... that all the gases when subjected to an equal rise in temperature expand by the same amount. Avogadro therefore derived his hypothesis. He also made it clear that the gas particles need not be individual atoms but had made a distinction between the atoms of a substance and its molecules. Avogadro himself was born on June 9, 1776 in Turin, Italy. He began his career in 1796 by obtaining a doctorate in law and practicing as a lawyer for ...
- 109: John Dalton
- ... rate of diffusion of gases. His analysis of the atmosphere showed it to be constant in composition to 15,000 feet. He devised a system of chemical symbols and, having proved the relative weights of atoms (particles of matter), in 1803 arranged them into a table. Dalton discovered butylene and determined the combination of ether, finding its correct formula. Finally, he developed his masterpiece of synthesis—the atomic theory, the thesis that all elements are composed of tiny, indestructible particles called atoms that are all alike and have the same atomic weight. In 1817 he became president of the Philosophical Society, an honorary office that he held until his death on July 27, 1844 in Manchester England ...
- 110: Salt Water Can Support An Electrical Current
- ... when dissolved in water, the common solvent. All three ionize, go through the process of ionization, by breaking up into their basic chemical components when dissolved in water. Ionization is the formation of electrically charged atoms or molecules. Atoms are electrically neutral; the electrons that bear the negative charge are equal in number to the protons in the nucleus bearing the positive charge. When sodium combines with chlorine, however, to form sodium chloride (salt ...
