he atom or Atomos, which means uncuttable or indivisible, took many years to get to our understanding now. Back then they didn’t have the technology that we have now like microscopes, to figure everything out. Some important people who helped were Greek philosopher Leucippus and his student Democritus. They were the first came up with the idea that matter is made up of of tiny particles. They thought that if you cut something in half a lot times, that you will eventually reach a particle that can't be cut anymore. The next big discovery in the atom didn’t come until hundreds of years later by James Dalton, who stated that atoms of different elements have different masses. Throughout Dalton's life as a chemist he had many theories of the
Carla the Carbon atom is a free spirit. She wanders through the atmosphere, moving with the wind. Carla floats from one cloud to the next, without a care on her mind. One day, she was floating in the air, and was joined by two oxygen companions, Oscar and Octavius. Her two companions transformed her into a carbon dioxide molecule. Her new status as a molecule allowed her new privileges, like the ability to enter plants and to take part in plant and animal respiration. Carla was now a part of an exclusive club.
John Dalton wrote the modern atomic theory, a fundamental component of that is, the mole ratios of elements in a compound will be small whole numbers.
The Manhattan Project was one of the most notorious and catastrophic projects in United State history. A bomb that took years to perfect and made the U.S. gamble millions of dollars on new technology that wasn't certain to work. All the secretive facilities scattered all over the U.S. contributed to the creation of a futuristic weapon of mass destruction beyond anyone’s imagination. The atomic bomb caused thousands to die and left years of remnant radiations. The Manhattan Project will forever remain as one of the greatest “successful” catastrophic discoveries in human history.
Imagine you have a small child, son or daughter. They’re just playing in the park all
On August 6th, 1945, the first atomic bomb to ever be used in the history of the world was dropped on Hiroshima. The result of this bomb killed roughly 80,000 people from the blast itself, and tens of thousands more due to radiation poisoning. After a few days passed, the United States dropped another nuclear bomb on Nagasaki, and threatened to drop another if the Japanese did not surrender. The bombs that were dropped on Hiroshima and Nagasaki lead to the Japanese surrender to the United States, removing them from the war. While the use of this bomb was likely necessary at the time, was it an ethical decision? The lives that were affected from this blast were not just of those who experienced it, generations later, people who weren’t even alive at the time were faced with trauma as well. With that being said, the dropping of the bomb might have been necessary, but it was an unethical decision, even though the Japanese made it perfectly clear that they will fight until the last civilian.
WWII was the bloodiest war in history. With over eighty million deaths, more than 50 of which were civilians. Some of these deaths occurred when armies stormed towns, but many of those deaths came from the atomic bombing in Japan. The atomic bomb is the most powerful weapon humans ever created. When it was dropped on Hiroshima and Nagasaki, the effects were unparalleled. The atomic bomb dropping was severe, but we warned Japan, and the area will be inhabitable in about 14 days. If we did not drop the bomb, there would have been many more casualties than there were, both American and Japanese
On August 6, 1945, in the city of Hiroshima, Japan, a nuclear bomb was dropped. 70,000 innocent people died that day, and water and food was polluted with radiation from the deadly weapon. A second city was bombed two days later, and thousands more lives were lost. Various questions have risen from the history of the bombing, as to whether it was necessary or not. Would the death toll be reduced? How would the war turn out?
At the beginning of the twentieth century a scientist called Albert Einstein had a special theory about atoms. His theory was that atoms had a lot of energy locked within them. After this theory was published scientists worked hard to prove that this theory was true. After thirty years of experiments they discovered that within the nucleus there is a lot of energy and splitting the atom would release it.
This information has not always been know to man though. Thankfully scientist such as J.J Thompson, Ernest Rutherford, and James Chadwick were able to perform experiments to shed more light on what the atom was made of. The electron was first found in 1897 by J.J Thompson; shortly after in 1911 the nucleus was discovered by Rutherford, leading to him later discovering the proton in 1919. Before James Chadwick discovered the neutron many scientists believed that there were additional protons in the nucleus, along with the equal number of electrons to cancel out the additional charge. Then in 1920 Rutherford thought that the protons plus the electrons made up a new particle but it was never confirmed. After a few years of study John Chadwick was able to discover the neutron through unidentified radiation experiments, one experiment in particular caught his eye Frédéric and Irène Joliot-Curie had studied unidentified radiation from beryllium as it hit a paraffin wax target. This experiment encouraged Chadwick to do some of his own experiments in 1932 which made him believe that the radiation ejected from beryllium was in fact a neutral particle about the mass of a proton. He also tried many other targets besides the paraffin wax, these included helium, nitrogen, and lithium. These experiments led Chadwick to find the the mass of the new particle was more than the proton, he also found out that the neutrons have no
Thomson’s discovery of the electron in 1897 and the atomic model, with his findings of the atom containing electrons, each with an individual unit of negative charge. Thomson also found that electrons were very light when compared to the mass of the atoms in which they came from. This is because atoms were known to be electrically neutral, the remainder of the atom had to be positively charged and form most of the weight in the atom. Thomson used his plum pudding model of the atom to present this. How did thomson discover the atom? Thomson discovered the atom through his use of Crookes, or cathode ray, tube in his experiments. He showed that cathode rays were negatively charged, also he looked at positively charged
In the 1950’s tension was rising in the cold war, having successfully tested a nuclear bomb the U.S decided to enter the “New look” which caused America to depend on Atomic weapons more, and the U.S. was willing to supply allies with atomic weapons. Records show that in February of 1958 the U.S said that it would prefer that japan use an appropriate amount of atomic weapons for self-defense purposes under the arrangement similar to the NATO’S ”nuclear sharing” deal. This discovery was found by Akira Kurosaki who is an associate professor at Fukushima University. He uncovered this document at the U.S. National Archives in Maryland which was never reviled to the public. Japan wanted to know exactly how the atomic weapons would be used but the
The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter.
First, research began with the question: What are the opinions of Iraqi politicians and political leaders of the United States of America (U.S.), United Kingdom of Great Britain and Northern Ireland (U.K), and Union of Soviet Socialist Republics (U.S.S.R.) atomic testing and policy in the 1950s? After preliminary research, the focus turned to the Baghdad Pact Nuclear Research Center. First, the Baghdad Pact was identified as the common link between U.S., U.K., and Iraqi interactions. By reading meeting notes for the different meetings of the Baghdad Pact’s Economic Committee, the Scientific Council was discovered and within the funding for the Scientific Council was the Baghdad Pact Nuclear Research Center. The center, largely funded by
On August 6th and 9th, 1945 the first atomic bombs were dropped on Hiroshima and Nagasaki Japan. With the use of these new weapons a door was opened that could never be closed, a new and uncertain era was now upon the world, and the use of atomic power could mean the betterment or destruction of a nation at a moment’s notice. Whether you like it or not, you live in the atomic age and it can have many implications that you may or may not know about.
