- 2124: Could the Greenhouse Effect Cause More Damage?
- Could the Greenhouse Effect Cause More Damage? John Harte is an ecologist from the University of California at Berkley. He is trying to find out whether heat stimulates further trace-gas from solid or not. He is going to conduct an experiment that ... elevations might melt up to two months sooner. In Colorado that would constitute March as May. As a result, the soil will dry quicker and will be much warmer than usual when May rolls around. John Harte says it would be like expanding summer at the expense of winter. That means plants that usually start to bloom just as the snow begins to melt will bloom sooner then the pollinators of ...

- ... Council, the American Water Works Association, the American Medical Association, and the World Health Organization. All of these organizations endorsed fluoridation (Waldbott pg. 277). However in 1977, the fluoridation controversy was brought back up by John Yiamouyiannis. A committee was commissioned to clear up the fluoride controversy once and for all. But it did not, it just raised it even more. Yiamouyiannis led this committee. Yiamouyiannis in his statement to congress ... Doubleday, New York, 1968. 2.

- 2126: Historical Development of Atomic Structure
- ... came the chemists and physicists of the 16th and 17th centuries who discovered various formulae of various salts and water, hence discovering the idea of a molecule. Then, in 1766 was born a man named John Dalton born in England. He is known as the father of atomic theory because he is the one who made it quantitative, meaning he discovered many masses of various elements and, in relation, discovered the ... known. His chart and theories gained acceptance by the scientific world when three elements he "predicted"—gallium, germanium, and scandium—were subsequently discovered In 1856 another important figure in atomic theory was born: Sir Joseph John Thomson. In 1906, after teaching at the University of Cambridge and Trinity University in England, he won the Nobel Prize in physics for his work on the conduction of electricity through gases. He discovered what ...

- ... routinely monitor stratospheric ozone levels over the Antarctic stations at Halley Bay (76°S 27°W) and at Argentine Islands (65°S 64°W). Analysis of ozone measurements in 1984 by a team led by John Farnam, made the startling discovery that spring values of total ozone during the 1980-1984 period had fallen dramatically compared to the earlier period between 1957-73.

- 2128: Atoms
- ... that these particles could not be cut. This went against the present day theory of Aristotle which was that matter could be cut infinitely. Unfortunately for Democritus, his theory was not accepted in his lifetime. John Dalton came up with an atomic theory of matter in 1803. In his theory he stated four theories. 1.)All mater is composed of atoms 2.) Atoms of same elements are the same 3.) Atoms ... and chemistry. One mistake of Dalton was his belief that atoms were round and hard. This became the primary ambition for scientists after Dalton, to find out the structure of an atom. In 1897, Joseph John Thomson discovered electrons. Using a tube, magnets and charged plates, he sent ray particles through various experiments changing the position of the charged plates. By changing the plates, he discovered he could also change the ...
- 2129: Project Mercury
- ... and height requirements, NASA selected seven to become U.S. astronauts. There names, Lieutenant M. Scott Carpenter; Air Force Captains L. Gordon Cooper, Jr., Virgil “ Gus” Grissom, and Donald K. “Deke” Slayton; Marine Lieutenant Colonel John H. Glenn, Jr.; and Navy Lieutenant commanders Walter M. Schirra, Jr., and Alan B. Shepard, Jr. Of these, all flew in Project Mercury except Deke Slayton who was grounded for medical reasons. He later became ... his ship, Liberty Bell 7, through flight for just 15 seconds longer than the previous mission. The next Mercury flight was accomplished using an Atlas booster. On February 20,1962 it fired up and launched John Glenn, Jr., inside Friendship 7, into orbit. Glenn orbited Earth three times and when he returned the country celebrated. Just three months later on May 24 Scott Carpenter also orbited Earth three times in Aurora ...

Other attempts to incorporate electromagnetism into the basically geometric formalism of general relativity were made by Hermann Weyl (1918) and more recently by John Wheeler; although some theories are more esthetic than others, all lack the connection with quantum phenomena that is so important for interactions other than gravitation. More-recent attempts at unification have been made from the ...
