John Dalton

John Dalton was one of the most memorable chemists and physicists of the 18th and 19th centuries. He actually came from very humble beginnings, being born within a Quaker family that lived in Cumberland, England. His father was a weaver, but young John Dalton's intelligence and ambition placed him on the fast track during his early teenage years.

John Dalton

For example, he started to run his own Quaker school alongside his older brother when he was just 15 years old. He wanted to pursue a career in law or medicine from an early age, but he was met with a lot of opposition from his close relatives and friends. He also found out later in life that he suffered from a very rare form of color blindness (deuteroanopia) in which he was able to only identify yellow colors. However, John Dalton did not allow these minor setbacks to stop him from pursuing his dreams and striving to reach his peak potential in life.
An Ambitious Journey of Learning

Dalton followed in the footsteps of a close mentor and friend, Elihu Robinson, who was a very prominent Quaker at the time that was widely known for his skills in meteorology and instrument making. Robinson was the one that influenced Dalton to go against the grain and ignore the opposition that he received from his family in order to pursue his interests in mathematics, science and meteorology as well. This journey led him towards making several significant strides within the world of science in the years to come.

John Dalton's early experiments focused on being able to measure the pressure of steam at different points of temperature ranging between 32 and 212 degrees Fahrenheit (or 0 and 100 degrees Celsius.) He was able to conclude from these experimentations that the standard variation of vapor pressure within every single liquid is equivalent. He was able to use his studies to further improve on the studies that had already been published by scientists and physicists that came before him, such as Joseph Louis Gay-Lussac - the scientists that developed the Gay-Lussac's Law. However, it was John Daltons' work on his atomic theory within the world of chemistry that earned him a place in the science textbooks throughout history.
Dalton's Atomic Theory

There were five key points that John Dalton was able to develop within the atomic theory. The first point was that there were many different elements that were made out of very tiny small particles that were named atoms. The second point of Dalton's atomic theory was that those atoms within a specific element are actually identical in mass, size and a variety of other properties as well. The third point concluded that atoms are not able to ever be created, destroyed or even subdivided regardless of what may happen to them through experimentations and other research studies.

The fourth point of Dalton's atomic theory showed that a variety of different atoms within a wide variety of elements are able to combine in whole number ratios in order to mathematically create chemical compounds. The final point of this widely known theory that is still being taught in science classes around the world today is that, within a chemical reaction, atoms are separated, combined and also rearranged.

Rumor Has It

Rumor has it that John Dalton was the first creator of the made for TV movie Sharknado except in his version everyone was dressed as a Quaker and instead of sharks, ducks were flying out of tornadoes eating everyone. He called it Quacknado.
