The African American inventor I decided to do a report on is Lloyd Hall. He was not only a black inventor but he also a chemist. Lloyd Hall received his Bachelor of Science from Northwestern University in 1914, a Master of Science from Northwestern in 1916, and a Doctor of Science (D.Sc.) from Virginia State College in 1944. He also served as chief chemist for John Morrel and Company of Ottuma, Illinois (1919-1921) and became President of the Chemical Products Corporation, Chicago from 1921 to 1924.
For instance he invented the cotton gin in 1793. He went to plantation owners named Catherine Green and Phineas Miller. Catherine said it was very hard to take out the seeds from cotton balls. So they asked him to make the cotton gin for the south. Phineas Miller said he will pay all cotton gin expenses.
He tried and tried to stop the transformations at times he proved successful; but it did not last for long. This was an advancement in science.
Seeing as he was a doctor he had access to dead bodies which he would take and make insurances claims off them to make money. He was also thought to have caused the death of a childhood friend when they were young and would often experiment on animals. But with that being said he was also known to be a very bright
He felt jubilant that his invention would help the society. The council of scholars did not like the idea of his invention for many different reasons. The main reason is that they didn’t believe in that individuals ideas don’t exist. The knowledge of individualism and creativity is not allowed. “Our blessing upon you, our brothers!
In the summary of the book “What The Dog Saw” in part one “John Rock’s Error” the author, Gladwell, talks about John Rock , a religious man, devoted to his church, married, and he had five children. In 1960, Rock invented birth control pill, and the FDA approved it. He become famous and he was appearing on TV and his name was on the news paper. Also he was the first one to extract freezing egg at Harvard Medical School. It was great for women to have protection from unwanted pregnancy.
A few other scientists named Crick and Watson decided to take a slightly different approach. Since we knew the four elements that made up DNA, and we knew how those
In the beginning of the Canon’s experiments, he actually believed that alchemy worked. Through his experimentations, he caused several chemical reactions with different substances. However, after multiple failed tests he decided that he would have to use alchemy as a hoax to fool other people for their money (Rossignol 40). He traveled the land, persuading a mob of people to donate
Joseph Wilbrand was a German chemist who would pave the way for one of the most deadliest explosives. He discovered one of the most important chemical compounds of the 18th century. Born August 22, 1839 In Giessen, Germany, the town he grew up in was about 200 miles away from Munich with a population of 80,000 people. His full name is Julius Bernhard Friedrich Adolph Wilbrand but he would go by Joseph. His father was a German forensic scientist, his name was Franz Joseph Julius Wilbrand, and there's no record of his mother.
Urea Wӧhler was trying to make ammonium cyanate, but discovered instead that the double displacement reaction that occurred produced urea. His discovery was purely accidental, but it answered some deep questions about science and chemistry that were hot topics at the time. Urea was known to have been created in biological processes, but had never been synthesised. It was amazing to discover that something produced from biology could be made by purely chemical means. This was an earth shattering finding to those who supported vitalism, a moment that believed that these two fields would not mix, and was the dawn of organic chemistry and our understanding of life as a complex electrochemical system.
He thought that if he heated it up enough, he could kill the microorganism and still preserve the product. He called it the pasteurization process. Many companies today still use his process to make their products safer.
During his public lectures he would discussed his findings and actually became rather popular, centered on his predictions of the weather which led people to think that he could predict future events and offered him a position to direct public affairs. He
Art Nouveau depicted a more whimsical light on women. Gender roles in society were changing with the beginning of war which meant the media’s view on women was also changing. Men heading off to war caused a shift in social stereotypes and woman were forced into the working class. Although several posters still used the idea of women being mere sex objects to gain appeal, such as Howard Christy’s Gee!! I Wish I Were a Man 1917 poster, the shift in focus was on recruitment and women 's involvement in maintaining life while men were off fighting a war.
Many ideas led him to believe what he believed. One of them was, James Hutton’s ideas about geological change. His theory consisted that sediments, rocks, soil, etc were made after the great flood and new species “rose” from that disaster and that it’s a cycle. Charles Lyell’s theory also shaped his thinking. Lyell wrote the book of “Principles of Geology”, where Hutton became famous.
Which Scientific Method did Darwin Use? Francisco J. Ayala argues that there is a contradiction between how Charles Darwin portrayed his methodology to the public and how he portrayed his methodology in his personal notebooks. The book, The Origin of Species, explains that Darwin used inductive reasoning in order to develop his theory. Specifically, he wrote that he acted on true Baconian principles and without any theory collected facts on a wholesale scale. Historically, the main method of reasoning used in Darwin’s time was the inductive method.
