Werner Heisenberg worked right around the time of James Chadwick. He discovered that neutrons, electrons and protons do not have a direct connection. His discoveries introduced atomic physics. He found out that the number of neutrons are not always the same. One thing led to another and the discoveries of Heisenberg helped to create the nuclear bomb.…
Although Joseph John (J.J.) Thomson (1856 - 1940) was mainly a physicist, his discoveries are closely connected to the chemical community. Thomson used Crookes high vacuum cathode ray tube in his discovery of electrons. He found the green beam produced by the cathode ray tube was a completely negatively charged material. Experimenting with different electrically charged plates and magnets in the cathode ray tube and observing the deflection of the rays he had enough evidence to say that particles smaller than atoms existed. By doing this experiment multiple times he compiled enough data to conclude that the mass of one of these particles, which he called an electron, was lighter than an atom of hydrogen by around 2,000 times. He also found the ratio of charge to mass (e/m) would be the same for any electron.…
Have you ever heard about Benjamin Banneker? Well, he is an amazing scientist that has tremendously impacted the world of Science. To start off, Benjamin Banneker was born on November 9, 1731, he was born in Baltimore County, Maryland. Unfortunately, he died in October 9, 1806 at the age of 74. As a child Benjamin attend a nearby Quaker school for several seasons. An unsual circumstance from his childhood is that he taught himself literature, history, and mathematics. As you can tell life in the 1800’s was very hard for an African American.…

(McPhee, 2010) The scientists of the 19th centuries renewed their interest in the Atomic Theory •John Dalton suggested that all matter was composed of small particles - atoms, each element had a different atom and a different atomic weight, theorized that atoms could not be created or destroyed in chemical reactions (1804) •In his attempt to classify the elements by principles, Dmitri Mendeleev arranged the elements by their atomic weight, discovering the existence of periodicity of the atoms (1869) •J.J. Thomson discovered electrons through his cathode ray experiment and proved that atoms were divisible(1897) (McPhee, 2010), ("A brief history," 2005) 20th century concepts and discoveries •Earnest Rutherford discovered that there was a small, dense positively charged nucleus, predicted the existence of neutrons, stated that electrons move rapidly in the empty space around the nucleus (1909-11) •In continuation of his experiments J.J. Thompson determined that all particles had charges that were multiples of the same number •In 1913 Robert Millikan accurately determined the mass of election…
Throughout his lifetime, Benjamin Franklin accomplished several things, he was a postmaster, politician, firefighter, musician, an expert swimmer, and above all an extraordinary inventor and innovator. His inventions were fascinating, and have helped create the society we live in today. Because of him, we now enjoy simple things like fireplaces, electricity, and bifocals. Franklin’s first invention was invented in 1742 and was known as the Franklin Stove, much similar to what we call a fireplace today.…
Both John Dalton and Ernest Rutherford, among other great researchers and scientists, assisted in creating the atomic theory that exists today. Dalton's theory was the first modern atomic theory, but a part of it was disproven by Rutherford. Rutherford found atoms were not indivisible and that they consist of smaller parts and particles. Even though one of Dalton's ideas was proved wrong, his other thoughts still apply to today's atomic…
The quantum theory began in 1900; while the first initial commencement of studies was made when Max Planck suggested that energy is quantized. Progression has been made continuously to this theory from a variety of other scientists including Albert Einstein. Planck has successfully discovered a theory to provide an accurate outcome, becoming a more intelligent choice of study over the well-established Newton’s Law. Still to this day Max Planck’s quantum theory is the most advanced source of scientific studies on subatomic…
Werner Heisenberg was the scientist of a lifetime for many different reasons. Werner contributed to the theory of quantum physics, while also discovering allotropic forms of hydrogen and receiving the Nobel Prize for physics in 1932. Werner Heisenberg was a scientist of a lifetime because he thrived to learn as much about quantum physics, and other types of physics as possible he attended and worked at five different colleges, he also educated other people by giving lectures around the world to teach people about his studies, Werner is a scientist of a lifetime.…

The day that William Crookes was born (born on the 17th of June, 1832 in London) questions to the world were being thought of but only one man could answer those questions and that man would be William Crookes. William Crookes was most definitely one of the most influential scientific minds that the world has ever experienced. At first William felt that organic chemistry was the path to his life; although. When he discovered the element thallium his world was changed and the extremes of the universe opened up to him. The thought of creating this extravagantly intricate element, thallium made Williams head race like a speeding bullet. William Crookes was motivated by the possibility of creating a new element, causing him to do what ever it took for him to be able to get there; no matter the vicissitudes.…
Is Benjamin Franklin a good person, worthy of emulation by people today? Unfortunately, some people would say he is not, and that he is an arrogant old man. But, having read his Autobiography , I believe he is, as he was an amazing person, centuries ahead of his time. He rose up from poverty to being one of the most well known figures in history. Through the virtues he applied himself to, he was able to make massive cornerstone contributions to our society, from bifocals to the pro and con list, just to start off naming two.…
The Manhattan Project may have never come to fruition if it wasn’t for that one German physicist: Otto Hahn. Hahn, working with Fritz Strassmann, discovered that when uranium was bombarded with neutrons a radioactive barium isotope was among the products. Hahn immediately realized the importance of this and told one of his colleagues (who had fled Germany due to nazi racial laws), Lise Meitner, about his findings. Lise worked with her nephew Otto Frisch to replicate Hahn’s findings and conclude that fission had taken place. The duo immediately made their way to Copenhagen to tell Bohr of their theories. Bohr was soon to be in the United States at Princeton’s Institute for Advanced Study. (Hewlett and Anderson,…
In 1913, a Danish physicist named Niels Bohr put Rutherford's findings together with the observed spectra to come up with a new model of the atom in a real leap of intuition. I believe that the Bohr’s model of atom explains well about the atomic theory, because in his experiments it is shown and explained the structure of an atom. His famous suggestion is about that the electrons orbit around the nucleus of an atom. Bohr experimented with atomic spectrum that proved his suggestion.…
“Words may show a man's wit, but actions his meaning.” Although possessing the gift of a silver tongue, Benjamin Franklin allowed his actions to speak louder than his words as seen through his many contributions to society, threw his acts against authority, popular belief, and political involvement.
