He was writing the properties of the elements and arranging them. Until he realized, that by putting them in order of increasing atomic weight the next certain types of elements regularly occurred. The other person that helped develop the Periodic Table was Antoine
Thanks to this result, Neptunium-238 was created along with two other neutrons. However, even though plutonium was originally created in 1940, it was not announced publicly till 1946 because of wartime concerns ("It 's Elemental."). Thanks to this new element it has proven to be useful, but also
Throughout his life, Tesla was granted 111 U.S. patents and every electrical appliance today uses at least one of Tesla’s inventions. In addition to how Tesla affected the world, Einstein left his mark on America’s technology and inventions. One major invention Einstein contributed to was the atomic bomb. The invention of the atomic bomb was a turning point in World War 2 when they dropped the bombs on the cities of Hiroshima and Nagasaki. The atomic bomb forced Japan to surrender and end the war faster.
He graduated from Harvard University, then went to England and enrolled at the University of Cambridge. He later went to Göttingen University, where he graduated with a Doctorate. Throughout his life, he had professions such as an academic, an engineer, a scientist, and a physicist. He was most acknowledged as "Father of the Atomic Bomb" He led the Manhattan Project, the program that developed the first nuclear weapons during World War II, from 1942 to 1945. Robert was also the co-developer of the Born-Oppenheimer Approximation.
This model added to the advancement of quantum mechanics. c. Reason for listening: This topic is important because people often only think about Einstein’s theory of general relativity, but he offered so much more. d. Credibility: For my informative speech, I have conducted extensive research on the scientific contributions of Albert Einstein. e. Thesis Statement: People view Einstein work as just if he has only contributed a few things to sciences and physics, but he did a greater amount then the majority of people know. Preview of major points: In this speech, I will show you
The Gadget, the first atomic bomb, 1945. The nuclear test of the first detonation of a nuclear weapon was codenamed Trinity, but the atomic device was nicknamed The Gadget. The date of the Trinity test is usually considered to be the beginning of the Atomic Age. The gadget was an implosion-type plutonium device, similar in design to the Fat Man bomb used three weeks later in the atomic bombing of Nagasaki, Japan.
1831- Using his invention the induction ring, Michael Faraday proved that electricity can be induced (made) by changes in an electromagnetic field. Faraday’s experiments about how electric current works, led to the understanding of electrical transformers and motors. This experiment became Faraday’s Law, which became one of the Maxwell Equations (Administrator, 2007). 1890 - Heinrich Hertz (1857-1894) a German physicist, laid the ground work for the vacuum tube.
From energy he became his attention to chemistry, reading the houses of gases. inside only some years he advanced on the preceding information of gas chemistry, which identified best three "airs" (air, carbon dioxide, and hydrogen), via adding ten new ones, along with oxygen, nitric oxide, nitrous oxide, hydrogen chloride, ammonia, sulfur dioxide, silicon tetrafluoride, nitrogen, and carbon monoxide. He summarized his early outcomes in an essay of 1772, "On extraordinary types of Air," published in the Philosophical Transactions. The essay stuck the eye of Lavoisier, who furnished the theoretical framework with which to make sense of Priestley 's
In 1939, the scientific community, specifically German physicists had learned the secrets of splitting a uranium atom (The Manhattan Project” 2015). America realized that Adolf Hitler’s Germany obtained a massive amount of scientific talent. With their access had necessary raw materials and knowledge of the splitting of the uranium atom, they had the industrial capacity to produce an atomic bomb(“Manhattan Project”2014). The atomic bomb would eventually become the turning point of weaponry during World War II. On October 11, 1939, President Franklin D. Roosevelt received a letter from Albert Einstein about the splitting of the uranium atom which could be beneficial in developing weapons for America during World War II.
Entering the new century, 20th century’s physicists came up with a new branch of physics – quantum physics, which explains the behavior of matter and energy on the atomic and subatomic level. After the scientists work on this subject, they solved the mystery of tiny particles’ motions. However, a load of equations made quantum physics rename as ‘the hardest subject to understand’. Richard Feynman is well-known for a quantum physicist, the most difficult subject of the modern physics. However, he made a new diagram about the activity of photoelectric particles that public can easily understand.
The project included a group of top scientists, under General Leslie R. Groves, who worked around the clock to try to develop an atomic bomb within three years. The Americans and the British combined their efforts to research the development of the bomb and created plants and factories to work in. Multiple plants were created for three separate processes: electromagnetic, gaseous diffusion, and thermal diffusion. These plants helped to create plutonium and urainium 235, needed to manufacture the atomic
Optical Lenses by Amy Hogan The earliest known optical lenses date back to 750 BC in the assyrian empire. The first lense was know as the layard lense and was most likely used as a magnifying glass or to start fires. Many similar lenses have been found from ancient egypt, babylon, and greece. Ancient egypt and greece would fill glass spheres with water to achieve the same affect of lenses. Coincidentally lenses wasn't thought of until the middle ages.
Physics 132 Hasbrouck 212 Cassidy Grace Lab 6: Radioactivity Abstract In this experiment we studied the strength of radioactive elements using the properties of ionizing radiation. The sources we used in this experiment are alpha, beta, and gamma radiation. We also studies the principles of the Rutherford experiments in that the nucleus was found to be very small because the forces that hold it together and also that the protons and the neutrons reside in the nucleus.
