A man by the name of William Crookes was one of the main contributors to the new fields of physics and chemistry that emerged in the late 19th century. Crookes’ analysis of the photographic process in the 1850s inspired his work in the science of spectroscopy. Using techniques of spectroscopy Crookes discovered the element thallium. His efforts in discovering the weight of thallium in an evacuated chamber led to his research in vacuum physics.
When Crookes was sixteen he entered the Royal College of Chemistry. He studied under August Wilhelm von Hofmann as an assistant in 1851. A few years later while attending a meeting at the Royal Institution, Crookes met the physicist Michael Faraday, who convinced him to switch his specialty to physics

In doing so, Crookes needed to use vacuum tubes. By placing a miniscule amount of thallium within a vacuum tube, Crookes would be able to weigh it to obtain a precise measurement. In determining the accurate atomic weight, he constructed a vacuum chamber. While attempting to obtain precise measurements, he noticed the unnatural behavior of his balance in the vacuum. In response to the irregular balance, Crookes invented a device in 1873 called a radiometer. The radiometer is a light bulb-shaped device containing an object that resembles the figure of a weather vane, with black on one side to absorb radiant energy and polished silver on the other to reflect …show more content…
After the series of séances, Crookes began to explore spiritualism. Once Crookes began to talk about his encounters with ghosts to his more traditional scientific colleagues, they ended up feeling that he had lost all form of neutrality and became too attached to the spirits. After 1875 Crookes stopped all tests to contact spirits and all other paranormal phenomena, however; he still supported the Society for Psychical Research and served as the president in
George Washington was born on February 22, 1732 in Westmoreland County, Virginia. He attended school for approximately eight years. Washington lived with his mother until the age of 16. At the age of 15, Washington took a job as an assistant land surveyor. In 1748, he began working in the Shanandoah Valley to help survey the land holdings of Lord Fairfax. By 1749, he established a good reputation as a land surveyor and was appointed Culpeper counties official land surveyor.
William Henry Harrison, (1773-1841), was 9th President of the United States. The oldest president up until then, he was also the first to die in office, surviving only one month. With his known Indian fighting his was given the nickname “Old Tippecanoe” and “Old Tip.” He was the first presidential candidate to campaign actively for office. His election slogan was “Tippecanoe and Tyler Too!”
Boyle’s studies laid the groundwork of modern chemical analysis of the composition of matter. Among other scientific fields, there were many advances made in chemistry during the Scientific
Sir William Crookes became president of the British Academy of Sciences in 1898. Crookes invented the Crookes tube, a precursor to cathode ray tubes and he is credited with discovering the element thallium. When he was appointed president of the Academy, he gave a speech in which he said the human population would be facing mass starvation from food shortage as soon as 1930. He said that the way to prevent that and ensure the food stability of humankind would be to create a new fertilizer, utilizing nitrogen from the air, to improve crop
Frederick Mckay was born in 1834 April 13 Lawrence, Massachusetts. Frederick went to public schools in Boston, Milford, Massachusetts. In his early career, he wanted to be a musician but he had health care problems that wouldn’t let him be successful. Fred worked in his father’s shop called the “ Dry Goods Store “ in Milford. Frederick was diagnosed with tuberculosis and moved to colorado in 1894. Mckay had some difficulties when he moved in colorado so he had to move back to Massachusetts.
William James was a philosopher and psychologist but was most well known in the field of Psychology for developing the philosophy of pragmatism, or the Functionalist theory: "Theory of mental life and behavior that is concerned with how an organism uses its perceptual abilities to function in its environment." He was also the first Psychologist to be born in America.
Robert Hooke was born on July 28, 1635 in Freshwater, Isle of Wight, England and was deceased on March 3, 1703 in London, England. Hooke has many scientific accomplishments in his career ranging from works in astronomy to paleontology. He established Hooke’s Law, alaw encompassing that the force needed to extend or compress a spring by some distance “x” is proportional to that distance. Hooke also made immense contributions to horology, the study and measurement of time. His contributions in that field were improvements to the pendulum and a watch balance spring, an effective way to determine latitude.
Gladstone first came into power in 1968 aged 59. He dominated British politics from 1868-1894. Many people said that Gladstone was the Liberal party. Gladstone drove the Liberal party to success therefore he was able to describe his first ministry an era of Liberation.
“Dr. William Stewart Halsted was the first chief of surgery at the JHH” (Cameron, 2001). He played a huge role in its success in the beginning. He was an innovative and prestigious surgeon in the United States. He introduced the “local and regional anesthesia, the development of the intestinal suture; an operation for advanced breast cancer, an operation for the cure of an inguinal hernia, and the first successful resection of a periampullary tumor; and contributions to thyroid and parathyroid surgery, vascular surgery, and orthopedic surgery” Cameron, 2001). The two elements of his contributions were the launch of “the philosophy of safe surgery” and a system for teaching surgical residents in the United States. He assisted in the construction
Giacomo Luigi Ciamician was a well-known professor, Italian senate member, and Italian chemist who made brilliant discoveries and has many accomplishments that have impacted the way chemistry is practiced today. Ciamician was one of the founders of photochemistry. He discovered and experimented with solar energy, which is one of his greatest achievements. He also made discoveries with the periodic table that provoked questions from other scientists, causing a chain reaction of scientific breakthroughs. While Ciamician’s many discoveries mostly relate to chemistry, they vary greatly in content, showing that he was an individual of both intelligence and curiosity.
This article is going to evaluate what kind of person Robert Hooke is by a letter. Although Robert Hooke is well known for his great discover of the field of microbiology, there is some proof that Robert Hooke may take his advantage of his background in Royal society to take down his opponent. I come out this thought while I am digging the background of the people related to the letter, and I want to know the background of it and understand why he wrote the letter. I will go through the letter and the backgrounds of the people evolved and tell the story based on my research.
At age 20 Robert Hooke becomes a scientist, he had the abilities to do mechanical instruments.He became very famous for inventions he made. The inventions that he made that we know today are the Universal Joint,Telescope,Balance Wheel,and the Diagram.Because of his inventions people called him Hooke England’s Leonardo Da Vinci.He impressed his teacher by learning Greek and latin,and learning six old books in mathematics called “Euclid’s Elements’’ less than a week.He was described as polymath because he excelled various disciplines of astronomy and biology,to architecture,paleontology and even medicine.
Throughout William Rankine’s life, he has accomplished many achievements in his life. When he was just 18, he won two Gold Medals for two different essays. One essay was on a theory called the Undulatory Theory of Light. He got these awards in his only two years attending the University of Edinburgh where he studied sciences. Rankine became somewhat popular and joined the Royal Scottish Society of Arts in 1842. When he was thirty-one years old, he won the Keith Prize in which when he was thirty-four, he joined another society called the Royal Society of Van Diemen’s Land in which is now called the Royal Society of Tasmania. During that time, he conducted an analysis of his own following the works of Clapeyron and using Sadi Carnot’s law to test his hypothesis. William Rankine later was elected to be the first President of the Institution of Engineering and Shipbuilders in Scotland which led to his vice presidency
