404 BCE
Egyptains Revolution
The Egyptians successfully revolt against Persian rule -
400 BCE
Democritus
Born 460 BC and Died in 370 BC he created the idea that atoms exist -
Napoleonic Wars
France's revolution, then a series of wars that ranged France against shifting alliances of European powers -
John Dalton
Born September 5 or 6, 1766, and died July 27, 1844. Dalton's atomic theory suggested that all matter was comprised of indivisible and indestructible atoms with distinct masses and properties, -
Michael Faraday
Born, on September 22, 1791, and died on August 46 1887. Electromagnetic: the "induction" or generation of electricity in a wire using the electromagnetic effect of a current in another wire. -
Eugen Goldstein
Born September. 5, 1850, and died on December. 25, 1930. He discovered what he termed Kanalstrahlen, or canal rays, also called positive rays; these are positively charged ions that are accelerated toward and through a perforated cathode in an evacuated tube. -
Death of Van Gogh
Artist Vincent Van Gogh died in France at the age of 37 after shooting himself -
JJ Thomson
Born December 18, 1856, and died on August 30, 1940. Thomson discovered the electron and then went on to propose a model for the structure of the atoms -
Ernest Rutherford
he discovered that atoms have a small, dense nucleus at their center, fundamentally changing the understanding of atomic structure. This led to the development of the Rutherford model of the atom. -
Robert Millikan
Millikan's experiment involved balancing tiny charged oil droplets in an electric field and measuring their rate of fall under gravity. By carefully analyzing the behavior of the droplets, he was able to determine the elementary charge of the electron with great precision. -
Niels Bohr
He proposed that electrons orbit the nucleus in specific, quantized orbits and that an electron could move between these orbits by absorbing or emitting energy in the form of light. -
The Mexican Revolution
The Mexican Revolution was in full swing during 1913. In February 1913 took place, a critical series of events led to the overthrow and assassination of the democratically elected president, Francisco Madero, and the rise of General Victoriano Huerta. -
World War 1
World War I was a global conflict primarily between the Allied Powers and the Central Powers. It was sparked by the assassination of Archduke Franz Ferdinand of Austria-Hungary but was driven by deeper causes like nationalism, militarism, and complex alliances. The war featured brutal trench warfare, new technologies like tanks and chemical weapons.It ended in 1918 with an armistice, and the Treaty of Versailles in 1919 placed heavy reparations on Germany. -
Edwin Schroedinger
Schrodinger's wave equation describes how the quantum state of a system changes over time. It provided a mathematical framework for understanding the behavior of particles at microscopic scales, such as electrons in atoms, and played a crucial role in the development of quantum theory. -
Werner Heisenberg
The discovery states that it is impossible to precisely measure both the position and momentum of a particle at the same time. The more accurately one of these properties is measured, the less accurately the other can be known. This idea challenged the deterministic views of classical physics and became a cornerstone of quantum mechanics. -
James Chadwick
Through his experiments, he identified the neutron as a neutral particle within the atomic nucleus, which was crucial for understanding atomic structure and led to advancements in nuclear physics. -
World War 2
WW2 was a global conflict between the Allied Powers and the Axis Powers It began with Germany's invasion of Poland and led to widespread battles in Europe, Africa, and the Pacific. Key events included the Holocaust, the Battle of Stalingrad, and the U.S. bombing of Hiroshima and Nagasaki. The war ended with the Axis surrender in 1945, resulting in over 70 million deaths and reshaping global politics(1939-1945)
