Nuclear Technologies Timeline Even though the ancient Greeks correctly theorized that everything was made up of simple particles, which they called atoms, it wasn't until the beginning of the 20th century that scientists realized the atom could be split.
Nuclear physicists such as Britain's Joseph John Thomson and Denmark's Niels Bohr mapped out the atom's elementary building blocks the electron, proton, and neutron and paved the way for the discovery of nuclear fission—the process that transformed the atom into a new and powerful source of energy.
Today atomic energy generates clean, low-cost electricity, powers some of the world's largest ships, and assists in the development of the latest health care techniques. Special theory of relativity German-born physicist Albert Einstein introduces his special theory of relativity, which states that the laws of nature are the same for all observers and Technologies in consumer research essay the speed of light is not dependent on the motion of its source.
Einstein wins the Nobel Prize in physics in for his work on the photoelectric effect. Neutron is discovered English physicist and Nobel laureate James Chadwick exposes the metal beryllium to alpha particles and discovers the neutron, an uncharged particle. It is one of the three chief subatomic particles, along with the positively charged proton and the negatively charged electron.
Alpha particles, consisting of two neutrons and two protons, are positively charged, and are given off by certain radioactive materials. His work follows the contributions of New Zealander Ernest Rutherford, who demonstrated in the existence of protons.
Chadwick also studies deuterium, known as heavy hydrogen, an isotope of hydrogen used in nuclear reactors. Cockcroft teams Walton to split the atom British physicist John Cockcroft teams with Ernest Walton of Ireland to split the atom with protons accelerated to high speed.
Their work wins them the Nobel Prize in physics in Named for its inventor, physicist Robert Van de Graaff, the generator gathers and stores electrostatic charges. Released in a single spark and accelerated by way of a magnetic field, the accumulated charge, equivalent to a bolt of lightning, can be used as a particle accelerator in atom smashing and other experiments.
Manhattan Project The U. Robert Oppenheimer, to develop the first transportable atomic bomb. Other Manhattan Project teams at Hanford, Washington, and Oak Ridge, Tennessee, produce the plutonium and uranium necessary for nuclear fission. First controlled, self-sustaining nuclear chain reaction Italian-born physicist and Nobel winner Enrico Fermi and his colleagues at the University of Chicago achieve the first controlled, self-sustaining nuclear chain reaction in which neutrons released during the splitting of the atom continue splitting atoms and releasing more neutrons.
In case of fire, teams of students stand by, equipped with buckets of water.
Hiroshima and Nagasaki To force the Japanese to surrender and end World War II, the United States drops atomic bombs on Hiroshima, an important army depot and port of embarkation, and Nagasaki, a coastal city where the Mitsubishi torpedoes used in the attack on Pearl Harbor were made.
First nuclear-reactor-produced radioisotopes for peacetime civilian use The U. Army's Oak Ridge facility in Tennessee ships the first nuclear-reactor-produced radioisotopes for peacetime civilian use to Brainard Cancer Hospital in St. Atomic Energy Commission The U.
The commission is charged with overseeing the use of nuclear technology in the postwar era. Plans to commercialize nuclear power The U. When neutrons released in the fission process convert uranium into plutonium, they generate, or breed, more fissile material, thus producing new fuel as well as energy.
No longer in operation, the reactor is now a registered national historic landmark and is open to the public for touring.These critical thinking essay topics on consumer behavior will help you choose or compose one on your own. Check them, there is also a sample essay attached.
