Introduction
John Dalton was an meteorologist, physicist, and was best know as a English chemist. Also He was best known for proposing the modern atomic theory and for his research into color blindness, sometimes referred to as Daltonism in his honor.
1. “Berzelius' symbols are horrifying. A young student in chemistry might as soon learn Hebrew as make himself acquainted with them.”
2. “It's the right idea, but not the right time.”
3. “This paper will no doubt be found interesting by those who take an interest in it.” - Quotes 1,2, and 3 are from John Dalton.
John Dalton was born on September 6, 1766, in Eaglesfield, England. Dalton study the genetics of red-green color blindness and founded the concept of Dalton’s Law of Partial Pressures.

his brother and him were both born color-blind. Dalton's father earned a good amount of income but not the very best as a handloom weaver. When Dalton was a child, he was eager for a formal education, but his family couldn’t afford it because they were very poor and it was expensive. So they he knew that he had to help out his family with their finances at a young age.
After going to a Quaker school in Cumberland, when he was 12, he started to teach there. At 14, he worked as a farmhand for about a year, but he wanted to returned as a teacher. Once he returned, he was an aide at a Quaker boarding school in Kendal for four years, then he was promoted to principal of the school. He was a principal there for 7 years, which was 1793, at which time he became a philosophy and a math tutor at the New College in Manchester. During the New College, Dalton joined the Manchester Literary and Philosophical Society, which granted Dalton access to laboratory facilities. Daltons first research project pursued his great interest in meteorology by keeping daily logs of the weather, paying special attention to details such as wind velocity and barometric pressure—a habit Dalton would continue all of his life. His research findings on atmospheric pressure were published in his first book, Meteorological Findings, the year he arrived in

The condition had affected both him and his brother since birth, Dalton theorized that it must be an genetic thing that ran in his family. Dalton tested his theory to be true when genetic analysis of his own eye tissue showed that he was missing the photoreceptor for perceiving the color green. The result of this experiment, contributions to the understanding of red-green color blindness or also called, "Daltonism."
Dalton's passion in atmospheric pressures eventually led him to a closer examination of gases. While observing and recording data about the nature and chemical makeup of air in the early 1800s, Dalton learned that it was not a chemical solvent like other scientists had believed but Instead it was a mechanical system composed of small individual particles that used pressure applied by each gas
William Clark was ½ of the genius team that made their way through miles of unknown land, unknown nature, unknown natives, and came home with all but one voyager, who was killed of natural causes. William Clark and Meriwether Lewis were the first Americans to try and map the Louisiana Purchase area, and not only did they map it, they discovered allies, new plants and animals, and discovered new land and water routes that could be useful for future travelers.
... Royal Society. He discovered numerous things about matters such as light and gravity, and in 1703 was elected as president of the Royal Society.
“Carrying his own cross, he went out to the place of the Skull (which in Aramaic is called Golgotha). There they crucified him, and with him two others—one on each side and Jesus in the middle,” (John 19:17-18). Jesus Christ’s valiant life was terminated with a horrendous execution. Tom Robinson’s did as well. He lived his life in the name in the name of others, helping everyone that he could, going out of his way to save people, even Judas, who would betray him. Tom did this aswell, constantly assisting Mayella, she who would betray him in court. Jesus had followers who believed in his message, just as Tom had believers in his innocence. Jesus and his followers would face persecution, just as Tom and hisi believers would. The judgements and death sentences of Jesus and Tom would make them become martyrs. The Martyrdoms would be essential for their causes. Many aspects of Tom Robinson’s life and death
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.
In The United States the number of people in prison is over two million, and of those two million it is estimated that two thirds of them will be back in prison within three years (Correctional Populations). Some people argue that rehabilitation is the most effective way to handle prisoners, but the risks don’t outweigh the benefits, especially for murderers. Nobles was an example of a murderer who appeared rehabilitated, but under close examination of his actions, he was no more than a manipulating sociopath. Nobles was not rehabilitated because his actions in court showed how he felt, his faith was a facade, and he was a schizophrenic.
To this day Charles Carroll of Carrollton is best known for his political leadership in his hometown Maryland. Penning the First Citizen letters in 1773 was Carroll, a wealthy man who became a major role in the patriot movement. As a member of the Continental Congress, Carroll was one of the singers of the Declaration of Independence in 1776. In fact, He also helped to write Maryland’s Constitution of 1776. Once American independence was accomplished, he served in the United States Senate and the Maryland legislature.1 Being the last to live of the signers, Charles journey is full of schooling, political and religious matter, and being a signer of the Declaration of Independence.
Edward Barry Dalton is the only member of the regiment to have been the subject of a previously published work. A short biography including a selection of the surgeon’s wartime official correspondence entitled Memorial of Edward B. Dalton M.D. was complied and published as a tribute by his brother John Call Dalton shortly after his death in 1872. (John Call Dalton, Memorial of Edward B. Dalton)
When pondering on life as not only a blind child but also a deaf child, one might say perception of the world and life is impossible. In the movie The Miracle Worker, Helen Keller was blind, deaf and mute since she had been a baby. Helen was incapable of communicating to anyone. The question, “do you think she had an accurate idea of color,” to me, is defined through her inability to know the difference between colors and physical appearance on objects certain colors, for instance the sun being yellow. Because Helen was blind and deaf, she could not actually see the color pink or yellow I can see. Helen had never actually seen color; therefore an accurate idea of a color is nearly impossible.
Richard Taylor was a Confederate soldier. He followed after his dad’s footsteps and became a great man and one that many will remember. He made the Confederates proud by leading them to a lot of victories.
Hiram Revels was born on September 27, 1827 in Fayetteville, NC. Unlike the majority of African Americans in the south, Hiram was born to free parents. His father worked as a Baptist preacher and his mother was of Scottish descent. Because of his Scottage background he was believed to be mixed with African and Croatan Indian lineage. In a time when teaching African Americans was illegal, Revels had an opportunity to attend a school taught by a black women. His older brother Elias Revels owned a barbershop, which he inherited upon his sibling’s death. Two years later he left to continue his education and to obtain a job.
Robert Boyle is the most influential Anglo-Irish scientist in history. He played a key role in the history of science by establishing the experimental method, on which all modern science is based (Mollan). Also, with his assistant Robert Hooke, he began pioneering experiments on the properties of gases, including those expressed in Boyle's law. He demonstrated the physical characteristics of air, showing that is is necessary in combustion, respiration, and sound transmission. He also wrote The Sceptical Chymist in 1661, in which he attacked Aristotle's theory of four elements. This was an essential part of the modern theory of chemical elements.
Richard Angelo Early life of Richard Angelo Serial killer Richard Angelo was born on August 29, 1962, in the West Islip, New York location. He was the only child of Joseph and Alice Angelo. Richard’s parents would be educational teachers, Joseph Angelo would be a high school guidance counselor, and Alice Angelo would teach home economics.

In The End of the Classical, Peter Eisenman has enlightened the architecture community to his idea of the three fictions that have influenced architecture since the fifteenth century. These fictions are representation, reason, and history. Fictions are not inherently bad, but when it does not recognize itself as fiction and when it tries to simulate reality, it becomes a simulation. Representation created the simulation of meaning, reason created the simulation of truth, and history created the simulation of the timeless. The first fiction is representation.
Dalton was influenced greatly by the mathematician John Gough. Dalton while in Manchester became the teacher of math and philosophy at a college. He taught there until 1799. Dalton became a chemist and physicist after his teaching jobs. 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 was proved true.
