Began in Fort Sumter, South Carolina. North (partiots) versus South (confederates)
-
51,000 confederate and Union soldiers were wounded, missing, or dead in Gettusburgh. Lead by President Lincoln, the Union won.
-
Created by English chemist, J.A.R. Newlands, the Law of Octaves explains that the elements are arranged according to their atomic weight and those elements that have similar chemical and physical properties occur after the interval of seven other elements.
-
John Wilkes Booth (confederate) shot a bullet into the back of Lincoln's head
-
Democrat Andrew Johnson, a Democrat, accused of violating the Tenure of Office Act.
-
Dmitri Mendeleev, a Russian chemist, created the Mendeleev’s Periodic Table in 1869. The Periodic Table arranged the elements in order of atomic mass, physical, and also chemical properties.
-
UK physics professor, JJ Thomas, was one of the first to discover the negatively charged particles in the nucleus of the atom.
-
US versus Spain in Spain, US won. War was caused by demands by Cuban patriots for independance from Spanish rule.
-
The Plum Pudding Model was created in England by physicist JJ Thomson. The model is of the atomic structure and shows how atoms are made up of positive and negatively charged particles. Later on though, one of Thomson’s students, Rutherford, proved the model to be incorrect.
-
One of the most significant earthquakes of all time occured in San Francisco, Caifornia. Extended 80 kilometers, 8.0 on the Richter scale, 3,000 people killed.
-
Occured in North Atlantic ocean about 400 miles south of Newfoundland, Canada. Ship carried 2,200 passengers and crew. Designed by William Pirrie- thought to be world's fastest ship.
-
Niels Bohr worked with Ernest Rutherford to create the model to show how energy orbits around the nucleus. They proposed that an electron was restricted to quantized orbits but that the electrons can also jump between the orbits.
-
Henry Moseley, a British chemist, discovered that the measurements of wavelengths of an X-ray spectral line of elements emitted the same ordering as the atomic number.
-
Archduke Ferdinand of Austria was assassinated by a Serbian Nationalist in Sarajevo, Bosnia. Countries involved were Germany, Austria-Hangary, and Ottoman Empire against Great Britain, France, Russia, Italy, and Japan.
-
The positively charged particles contained in the nucleus of an atom were discovered in England by Ernest Rutherford shortly after World War I.
-
Created by Erwin Schrodinger, the equation describes the quantum mechanical behavior or the wave equation for the behavior of atomic particles.
-
US Stock market crashed, wiped out investors due to Wall Street panic. By 1933, Great Depression unemployed 13-15 million Americans and half the banks had failed.
-
James Chadwick, an English physicist, discovered the neutron, or an elementary particle devoid of electrical charge.
-
Adolf Hitler, dictator of Germany provoked global conflict but mostly involving Germany, Poland, and America.
