Vietnam

The Vietnam War, also known as the Second Indochina War, the Vietnam Conflict, or often in Vietnam the American War occurred in Vietnam, Laos and Cambodia from 1959[1] to April 30, 1975. The war was fought between the communist North Vietnam, supported by its communist allies, and the government of South Vietnam, supported by the United States and other member nations of the Southeast Asia Treaty Organization

Civil Rights Movement


Civil Rights movement 1964-1968, MLK,J., Birmingham, AL. contributed to equality of all races.

1st Atomic Bomb


the first atomic bomb was exploded at Los Alamos. This was on July 6, 1945.

Korea


Korean War 1950-1953. conflict between North and South Korea

World War 2

WW2-1939-1945

World War 1




The Great War spanned four years and involved many nation states.1914-1918

Manhattan Project


The Manhattan Project is the code name for the US government's secret project that was established before World War II and culminated in the development of the nuclear bomb was located at the University of Chicago under a squash court, quite incredibly. The following was said by a member of the project.

Inventor of Coca Cola


In May, 1886, Coca Cola was invented by Doctor John Pemberton a pharmacist from Atlanta, Georgia. John Pemberton concocted the Coca Cola formula in a three legged brass kettle in his backyard.

Chernobyl


The Chernobyl accident(the Ukraine) in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel and without proper regard for safety. The resulting steam explosion and fire released at least five percent of the radioactive reactor core into the atmosphere and downwind. 28 people died within four months from radiation or thermal burns, 19 have subsequently died, and there have been around nine deaths from thyroid cancer apparently due to the accident: total 56 fatalities as of 2004.

Louis de Broglie


In 1927,(Paris), Louis de Broglie came up with wave mechanics, a theory which has utterly transformed our knowledge of physical phenomena on the atomic scale.

Ellen Swallow Richards


Massachusetts….In 1887 Ellen Swallow Richards conducted an enormous, pioneering survey of drinking water in Massachusetts, which led to the establishment of water-quality standards and modern sewage treatment plants. Richards then pursued chemical studies to determine the ingredients in groceries, along with their quality, which eventually led to state food and drug standards.

Patricia Bath


Patricia Bath - (Harlem, NY. USA) In 1988, Patricia Bath invented the Cataract Laser Probe, a device that painlessly removes cataracts. Prior to this invention, cataracts were surgically removed. Patricia Bath founded the American Institute for the Prevention of Blindness.

Lloyd Hall



Chicago, 1925, Lloyd Hall(first african-american chemist) pioneered antioxidant use when he discovered that foods with fats and oils spoiled when certain ingredients react with oxygen in the air.

Hideki Yukawa


In 1947(osaka, Japan), Hideki Yukawa predicted K-capture, in which an electron in the lowest hydrogen energy level could be absorbed by the nucleus.

Dmitri Mendeleev


In St. Petersburg, Mendeleev is best known for his work on the periodic table; arranging the 63 known elements into a Periodic Table based on atomic mass.(1869)

Niels Bohr


1911 he made a stay at Cambridge, Niels Bohr passed on to a study of the structure of atoms on the basis of Rutherford's discovery of the atomic nucleus.

Ernest Rutherford


Rutherford deflected alpha rays with both electric and magnetic fields in 1903.

Werner Heisenberg


Werner Heisenberg's theory of quantum mechanics was published in 1925. For this theory and the applications of it which resulted especially in the discovery of allotropic forms of hydrogen

Enrico Fermi


In 1934, Enrico Fermi evolved the ß-decay theory, coalescing previous work on radiation theory with Pauli's idea of the neutrino.

Robert Millikan


In 1910, in Chicago, Robert A. Millikan had his earliest major success; the accurate determination of the charge carried by an electron, using the elegant "falling-drop method".

Erwin Schrodinger


In the Alps, Erwin Schrodinger made a profound discovery in 1927 by showing that the discrete energy states of Matter could be determined by Wave Equations.

Eugene Goldstein


In 1876 Eugen Goldstein demonstrated that cathode rays can cast shadows and that the rays are emitted perpendicular to the cathode surface. He then showed how cathode rays could be deflected by magnetic fields.


Max Planck


Max Planck was able to deduce the relationship between the ener gy and the frequency of radiation. In a paper published in 1900, he announced his derivation of the relationship: this was based on the revolutionary idea that the energy emitted by a resonator could only take on discrete values or quanta. The energy for a resonator of frequency v is hv where h is a universal constant, now called Max Planck's constant.


James Chadwick


In 1932, in Cambridge, Massachusetts, James Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons - elementary particles devoid of any electrical charge.



Joseph John Thomson in 1904 in New Haven, Connecticut discovered a method for separating different kinds of atoms and molecules by the use of positive rays, an idea developed by Aston, Dempster and others towards the discovery of many isotopes.


Linus Pauling


In 1922 in Pasadena, California, Linus Pauling discovered the structures of chemical bonding, amino acid and protein, and the molecular basis of sickle-cell anemia, among a variety of other achievements. He is generally considered among the greatest chemists of the twentieth century.

Henry Moseley


in 1913, When atoms were arranged according to increasing atomic number, the few problems with Mendeleev's periodic table had disappeared. Because of Moseley's work, the modern periodic table is based on the atomic numbers of the elements.


Albert Einstein


In 1905, Einstein based his new theory on the principle that the laws of physics are in the same form in any frame of reference. As a second fundamental hypothesis, Einstein assumed that the speed of light remained constant in all frames of reference.Later in 1905 Einstein showed how mass and energy were equivalent expressing it in the famous equation: E=mc2 (energy equals mass times the velocity of light squared). This equation became a cornerstone in the development of nuclear energy.

John Dalton






John Dalton’s theory was based on the premise that the atoms of different elements could be distinguished by differences in their weights. He stated his theory in a lecture to the Royal Institution in 1803. The theory proposed a number of basic ideas: Stockholm, Sweden. All matter is composed of atomsAtoms cannot be made or destroyedAll atoms of the same element are identicalDifferent elements have different types of atomsChemical reactions occur when atoms are rearrangedCompounds are formed from atoms of the constituent elements.
