Ernest Rutherford 1898
Ernest Rutherford was the founder and investigator of the nucleus. Henry Moseley, Hans Geiger and Albert Beaumont Wood influenced Rutherford. He later discovered that Thomson’s model wasn’t correct and in 1911 Rutherford used his well-known gold foil experiment to prove that the atom holds a very small heavy nucleus. His experiment was designed to use alpha particles released by a radioactive element as probes to the unseen parts of atomic structure. Rutherford's experiment shows how scientists must never just accept the current theories and models but they should always be putting to new tests and experiments to the test. Rutherford was defiantly one of the most successful scientists of his time although his most renowned

He also foresaw that economies based on non-renewable fuels were self-destructive. Soddy was and still is a successful scientist of the atomic model and theory thanks to his findings of isotopes.
The same elements exist in different forms, with nuclei having the same number of protons but different numbers of neutrons. This changed the theory of the atomic model. Soddy used the rather basic tools and used the ones available to him. This includes hand blown glass bulbs, carefully made and then evacuated to create what is commonly called a vacuum tube. Soddy used a radium sample closed and sealed on the inside of a glass container, which was quite thin, which was sealed inside an evacuated tube.
Niels Bohr 1922
Many things influenced Niels Bohr. An early influence was his father, Christian Bohr, who was a Physiology Professor. His most important contribution, which was his atomic model, was based on the one made by his mentor, Ernest Rutherford. Rutherford had inspired him to continue his passion and find out more about the atomic theory and with this changed Rutherford’s model

Electrons should move around the nucleus but only in specific orbits. When jumping from one orbit to another with lower energy, a light quantum is emitted. Bohr's theory could explain why atoms emitted light in fixed wavelengths.
Glenn Seaborg 1941 - 51
Dwight Logan Reid, who was a chemistry and physics teacher, influenced Glenn Seaborg to investigate the atomic theory and he did just that with a successful outcome changing the model of the atomic theory. He was the investigator of isotopes and with this discovered iron, with this finding came the discovery of hemoglobin, which can be found in human blood. He also developed iodine from his successful findings in his atomic experiments. Iodine is still used to treat thyroid disease today.
Glenn:
He discovered 100 new types of isotope and with this discovered iron, with this finding came hemoglobin in human blood. He developed iodine, which is still used to treat thyroid disease. His successes lead to the development of iodine and He developed the extraction process to isolate the plutonium fuel for the second atomic
He laid the foundation for the future development of radio, telephone, telegraph, and even television. He was one of the first people to demonstrate the existence of electric waves. Hertz was convinced that there were electromagnetic waves in space. Even though Hertz did not think his discovery was useful, it was a major discover in the field of Radio Technology. It later on it helped develop wireless communication (“History of Magnetism and Electricity,”
It was such a success that Franklin could retire at the age of 42. He then would take the time that he had now to pursue his fascination of science. Since he didn’t know if other scientists had discovered
Scientist continued to develop the world's knowledge of the atom. In 1896, Henri Becquerel accidentally discovered radioactivity(Doc.1). Furthermore, in 1911, Ernest Rutherford discovered atoms were made of smaller particles and that they had a positively charged nucleus(Doc.1). Throughout decades, scientist have honed ,developed, and continued in the study of the science of the
Linus Pauling Linus Pauling was a very important scientist who over seven decades of his life made many discoveries in multiple fields of science including: physical, structural, analytical, inorganic, organic chemistry, and biochemistry. He was born in the 20th century and contributed greatly to science field during this time. He is known for “Pauling’s Rules” and other inventions he is responsible for. He would also go on to write his own books detailing some of his work, he made very diverse discoveries and discovered many things in many different fields; which is very unique for a scientist. Pauling was an activist and was very involved and fought for causes he thought were important.
Once on the Republic, Rutherford finds out many things that he did not expect to occur. Rutherford learns many things that shakes him and often awakes him at night. As the days on the Republic go by, Rutherford begins to regret and wish he would have never stepped onto the ship. Rutherford explains how he feels about his presence on the ship. Rutherford says “I’d felt such dizzying entrapment” (Johnson 45).
Ben Franklin was an incredible scientist who wasn't afraid to leap into dangerous experiments. He was one of the first people to capture the power of lighting and electricity, using it to create things like the lightning rod. Ben Franklin found himself front and center of the new world, as he became famous for his scientific research. Ben Franklin was able to use his scientific knowledge to shape the new world with his inventions, experiments, and even gave people of all generations a new way to go through their everyday life. To start, Ben Franklin spent the majority of his career in science, studying and experimenting with the power of electricity.
"Speak little, do much," (Poor Richard's Almanac). This is a quote by Benjamin Franklin. Franklin used this quote as a motto for himself and did just as the quote says. He did not talk that much, but he did a lot. He had several inventions that are still used today and without them, life would not be the same.
George Washington Carver Throughout our lives we have all wondered whether or not our actions have had any historical significance, or if we will go only leaving a small mark on the world. Looking back very few people have successfully attained this immortality. George Washington Carver did. With his love for plants and his kind heart, Carver accomplished much with the motivation given to him at a young age leaving a large mark on the world.
Benjamin Banneker was an important mathematician who was also African American. Banneker was born on November 9, 1731 in Ellicott’s Mills, Maryland. He always had an interest in mathematics while his grandmother, a freed slave, taught him. His grandmother was not his only source of learning, though, for he also attended a Quaker school until the 8th grade (Benjamin Banneker (1731-1806), n.d., p. xx).
Introduction 1 Benjamin Franklin was always loved to read and write and it led him to his amazing accomplishments. 2 Some of his accomplishments he had were in all subjects that are in schools today. 3 His accomplishments consisted of the first battery, the bifocal glasses, and he made the Odometer.
Ben wrote a book about his experiments on electricity, that became extremely popular and even formed the basis of modern day electricity theory (Compton’s, p. 382). Not only did Franklin leave a great legacy as a scientist, but he also changed the course of American
At the same time, Rutherford's political reputation was
The standards he put forward in the book framed the premise for cutting edge electrical hypothesis. In 1752 he sent a record of his analysis to the Royal Society of researchers in London and to French researchers. The outside researchers were so inspired with his work that he was chosen a kindred of the Royal Society in 1756 and granted its Copley Medal. In 1773 he was chosen one of the eight remote partners of the Royal Academy of Science in
Although Franklin makes a point to say this experiment is about him, he also writes that “it may be well my posterity should be informed…” (Franklin 433). Franklin is writing this with the intent of others seeing his argument. He makes a clear point that this is the direction a perfect man should be heading towards.
In addition, some of Einstein’s discoveries, would go on to make the atomic bomb possible. Possibly one of the most famous equations ever, he created E =mc2. Einstein transformed the laws of time, space, and gravity (Encyclopedia of Scientists). He was the first person to abandon Newton’s light
