In chemistry there are many renowned scientists. One of the more well-known scientists is John Dalton. He revolutionized the way we view chemistry through his observations and theories. He had many theories that still affect us in the present day. One that stands out in particular is his atomic theory. Without all of his contributions our modern world could not thrive like it is currently.
John Dalton from a very young age was intelligent. Born in 1766 Cumberland, England he grew up with his family who were all tradesmen. When he was twelve years old he started as a teacher’s assistant at a Quaker school. He continued that role until he was fourteen. At fourteen Dalton went to a farm for a year. He later returned to the Quaker school and became an official teacher. For two years he worked at that school until he was promoted and became the principal. He taught as a public lecturer until 1793 when he moved to Manchester. Later he was invited to join the Philosophical Society and the Manchester Literary [“John Dalton Biography.”]. He joined and his membership granted him access to the laboratory. Dalton was a self-taught experimenter. He used the laboratory to initially study meteorology, which is the study of the atmosphere.
By one of his closest peers, John Daniell, Dalton was called the “Father of Meteorology” this is because he had a large influence over meteorology. While he was a teacher at his Quaker school Dalton learned a lot about meteorology mainly through two of his fellow acquaintances, Elihu Robison and John Gough [“John Dalton.” Encyclopedia]. They influenced him to pursue his studies in meteorology. Through their influence Dalton kept records of his own atmospheric observation until the day he died. He ended up with ...

...h Dalton’s theories and his laws on chemistry they still enormously affect us today. He was and still is a very important person. He received an honorary degree from the University of Oxford. He was also elected into the Royal Society of London and of Edinburgh. He was very well known when he was alive. After his passing, over 40,000 people showed up to his funeral. His contributions to science were so important that without them we would not be technologically where we are today.

Bacon became drawn in science during high school. She spent a brief time in Florida, where she attended a “ghettoized” school. African-Americans in that school were not encouraged in the subjects of math, physics, and chemistry. Causing Bacon to lose some of her desire for science temporarily. However, when she reverted to a racially varied school in Kansas, where those subjects were educated actively, her eagerness for science returned. It was a physics teacher who noticed Bacon’s interest in aquatic displacement and resistance, who also encouraged her to consider a career in meteorology.
John Dalton was born on September 6 1766 at Eagelsfield, Cumbria in England.Although he was born in England, he spent most of his life in Manchester.He was born into a Quaker family and while his family had food, they were still poor. His father Joseph was a weaver and John recieved most of his early education from his father. At the age of 12, John opened a school in Eagelsfield where he was the master. He was often threatened by the older boys who wanted to fight him because he was smarter, but he managed to keep in control for 2 years.Due to a poor salary, John was forced to leave his school and work in the fields with his brother. In 1781 John and his brother moved to Kendall. There John, his cousin George, and his brother ran a school where they offered English,Latin,Greek,French and twenty one mathematics and science course. Their school had sixty pupils. After twelve years at Kendall John started doing lectures and answering questions for mens magazines. John found a mentor in John Gough,who was the blind son of a wealthy tradesman. John Gough taught Dalton languages,mathematics,and optics. In 1973 John moved to Manchester as a tutor at New College. He immediately joined the Manchester Literary and Philosophical Society and in the same year he published his first book: Meteorological Observations and Essays. In his book Dalton stated that gas exits and acts independantly and purely physically not chemically. After six years of tutoring, John resigned to conduct private research while still doing tutoring at 2 shillings a lesson. In 1802 John stated his law of partial pressures. When two elastic fluids are mixed together ( A and B) they dont repel each other. A particles do not repel B particles but a B particle will repel another B particle. One of his experiments involved the addition of water vapor to dry air. The increase in pressure was the same as the pressure of the added water. By doing this experiment, John established a relationship between vapor pressure and temperature. John’s interest in gases arose from his studies of meteorology. He had weather equipment that was with him at all times and he was constantly studying weather and atmosphere. He also kept a journal throughout his life in which he wrote over 200,000 observations. In 1803, John made his biggest contribution to science: The Atomic Theory.
Linus Pauling was a creator with astounding intellectual abilities who was also active in many other areas as dictated by his interest and passion. His ideas and research into the nature of chemical bonds significantly changed the way that we understand the world.
John Dalton, born 6th September 1766, is known for developing the theory of the elements and compounds atomic mass and weights and his research in colour blindness.
Dmitri Mendeleev was one of the most famous modern-day scientists of all time who contributed greatly to the world’s fields of science, technology, and politics. He helped modernize the world and set it farther ahead into the future. Mendeleev also made studying chemistry easier, by creating a table with the elements and the atomic weights of them put in order by their properties.
Sir Alexander Fleming changed the world of medicine not only in his days but also in the world today. We have the medicines and antibiotics that we have today because of Alexander Fleming. His discovery was much needed in the world and I hate to think where we would be in the medicine world if he hadn’t discovered penicillin.
Inventor and astronomer Galileo Galilei is one of the most well-known scientists in the history of the world. Galileo has been credited for many astonishing inventions such as the pendulum and the telescope. Through many years of research and studious acts, he discovered behaviors of the universe that still hold true today. Galileo, “the Father of Modern Science”, changed the world.
I have chosen two of them who were in many ways just opposites. One is extremely famous and the other is almost unknown except to specialists. The most famous is of course Albert Einstein. He has significantly altered our view of the world with his Theory of Relativity.
Another important individual who drove history was the Italian astronomer and scientist Galileo Galilei. Galileo discovered something so important that it changed the selfish perspective that humans were the center of the universe and led to the growth of human knowledge. Utilizing mathematics and a telescope he had developed, Galileo observed that the planets revolved around the sun and not the Earth. This was a significant discovery because not only did it contradict what the church had taught, it also showed that the universe was not what it seemed. With this truth uncovered, many people began to fascinate over the universe. This triggered people to begin studying space extensively and eventually lead to present day space exploration. Galileo also left a lasting impression upon many great minds, such as Sir Isaac Newton, who used Galileo's research and theories to further his own studies such as the physical laws, and their properties.
These two scientists that made a difference in the world today is Sir Charles Darwin and George Washington carver. Sir Charles Darwin was born in Shrewsbury England on February 12 1809. His research of specimens around the world led him to come up with his theory of evolution and his views on natural selection. He went to the University of Edinburgh. Then we have George Washington carver was a famous African American scientist and inventor.
Dalton did a lot of experimenting, but did not test his experiments to make sure they were right. A good amount of his experiments were later proven to not be true. But his most famous theory "Dalton law", the modern atomic theory, proved true. John Dalton also published a lot of papers on atoms. His most famous article was on "absorption of gases by water and other liquids," this article contained his atomic theory.

While living on campus at Glasgow University, the family often visited the Netherlands and Germany. They were also quite fond of the Island of Arran, which they often visited. Being so close to water, William Thomson developed a fascination for the sea and the earth’s crust as well. When he was only ten years old he began his studies at Glasgow University. During his years at this institution he received many prizes and awards. He then attended Cambridge University to achieve the credibility he desired. Shortly after, he travelled to Paris to further study thermodynamics. When he was twenty-two, he became a professor of natural philosophy at Glasgow University. There he created a laboratory for physics students to actually experiment instead of just reading about physics in theory (Russell).
