Nuclear physics

Alchemists used to obsess over chrysopoeia, the transmutation of regular metals, such as copper, into gold. However, they were not aware at the time that copper and gold were two different atomic elements and instead believed them to be compounds. Thinking these metals could be changed chemically or physically in labs, alchemists pursued this dream to no advantage. Although it is not possible to change ordinary metals to gold through chemical reactions, physical reactions, radioactive decay, or nuclear fission, it is possible to change them through nuclear fusion. Common metal such as copper cannot go through physical reactions to turn into gold because the substance would only change phase. A physical reaction is the rearrangement of molecules…

worked and studied radioactivity and nuclear fission. Meitner’s way of working and studying led to the “radiochemical discovery” of nuclear fission. Her achievement was rewarded with a Nobel Prize for chemistry in 1944. Meitner is often used as an example of a scientific women who was “overlooked by the Nobel committee”. Lise Meitner demonstrates the arduous work she had to do in order to discover her accomplishment which in this case is the discoverment of nuclear fusion. Lise Meitner is an…

Ernest Rutherford was a chemist and a physicist that was born on August 30, 1871, in Spring Grove, New Zealand. He was a pioneer of nuclear physics and the first to split an atom. He was awarded a Nobel Prize in chemistry for his theory of the atomic structure. He discovered alpha and beta rays, that the atom could be split, and contributed to the Atomic Theory. He used the gold foil to see how to alpha and beta rays would bounce off off different atoms. Ernest was responsible for a remarkable…

Honor means great respect for what you have done especially big accomplishments. Honor is when someone respects you for your accomplishments. Scientist Ernest Rutherford was born on August 30, 1871, in Spring Grove New Zealand. A pioneer of nuclear physics and the first to split the atom in half he was awarded the 1908 Nobel Prize in Chemistry for his theory of atomic structure. His father James had little education and struggled to support the large family of 14 but his mother Martha worked…

Some believed, along with Rutherford and Chadwick that particles with no charge could be in the nucleus. Chadwick made many attempts and spent a very large amount of time trying to find the neutral particles. In 1932, Chadwick finally proved the existence of the neutron. In 1935, he received the Nobel Prize in physics for discovering the neutron. Discovering the neutron led to many other discoveries and changed science, such as neutrons being used to split heavy atoms apart, and atomic fission.…

College of London in 1904, Hahn made his first big discovery and contribution by discovering radiothorium, a radioactive isotope of thorium. In late 1905, Hahn moved to the Physical Institute of McGill University in Montreal, Canada. Here he worked with Ernest Rutherford, famous father of nuclear chemistry and many other chemistry achievements. Hahn during this time under Rutherford discovered a radioactive isotope of actinium, and investigated its and radiothroium’s alpha-rays (“Otto Hahn…

Expository Writing and Research and Argumentative Writing which focus on a variety of analytical writing and utilizing resources for the purpose of research. General Biology I and General Biology Lab I focuses on biological processes, cellularly and General Biology II and General Biology Lab II focus mostly on plant and animal ecology. General Chemistry I and General Chemistry Lab I is a pathway from high school chemistry to more advanced chemical principles and basics, experience in this field…

knowledge. If one is complacent, obtaining new knowledge will be difficult which will lead to no new applications, with no new technology one is unable to make new discoveries. Without the possibility of expanding human knowledge of the universe, the world would be bleak and unmotivated. For the second issue, technology does not make people lazy it is the way one uses technology that makes people lazy. Advancement in technology allows people to do things faster with less effort. How one uses the…

orn in Odessa, Russia in 1904, George was raised by his mother and father who were both teachers, until he was nine-years-old when his mother died. Neither were science teachers, but they helped George to learn how to speak Russian and French. He also learned German and English. Nineteen years old, and one year after the founding of the USSR, George went to the University of Leningrad to study physics. He and his friends would often discuss quantum mechanics which was cutting edge science at…

James Chadwick was a very intelligent boy, as a teenager he knew that he wanted to study physics and so he did. James Chadwick went to the University of Cambridge at the age of 17, in the year 1908. When he was 19 he was in his final year of his physics degree. James’ teacher was Ernest Rutherford another famous scientist who won the Nobel Prize for Chemistry, because of his studies on disintegrating the atom. After James turned in his research paper he graduated with first class honors. For…
