Great Basin College AMS 320 LAB 9 Objective In this lab we will perform an investigation to determine the half-life of a radioactive isotope Ba-137m. Introduction No other facet of chemistry has captured the attention of people in the latter half of the 1900s as the field of radiation. From the discovery of x-rays in 1900 to the destructive power of atomic weapons, we have seen a history that is very interesting. As discussed in class lecture, some atoms are unstable. Some will change into another element if given enough time.
Victor’s curiosity led him to creating the monster. There weren’t many people who accepted the idea of galvanism and things of the like in Frankenstein’s day. “On this occasion a man of great research in natural philosophy was with us, and, excited by this catastrophe, he entered on the explanation of a theory which he had formed on the subject of electricity and galvanism.” (Shelley, page 37). This quote illustrates that Victor is becoming more involved and studying more about creating life. I can’t imagine being seventeen or eighteen and thinking about how to bring something you have created from the dead.
Tesla left Edison’s company and began work on his own in advancing his research into alternating current. Upon hearing of Tesla’s new research and success in perfecting his alternating current technology, Edison shifted his focus to direct current research and development. When direct current became public knowledge, reports in the
I visited the Griffith Observatory on Sunday November 16, 2014. During my visit I was able to observe the Tesla Coil demonstration developed by the late Nikola Tesla. Mr. Tesla designed the coil to someday transport electricity by air wirelessly and free. The energy would come from the magnetic field and atmosphere producing high-voltage, low-current, and high frequency alternating-current electricity. He had some success in his research but investors found it impractical and refused to support further research.
After Franklin printed Photo 51, Wilkins decided it would be acceptable to secretly show Watson and Crick, who quickly decided to use the photo to their advantage. Moreover, Photo 51 led to many other great discoveries that Watson and Crick made, however, they never decided to credit Franklin. Because Watson was able to secretly study Photo 51, he could use characteristics from it to create the chemical model of DNA. In addition, Photo 51 became a crucial data source, and led to the creation of the DNA model, which confirmed the theory of the double helix structure. The discovery of the double helix structure from Photo 51 led to scientists being able to understand DNA, which also enabled them to learn more about diseases, and heredity.
Doctor Richard P. Feynman is a little known scientist to the public, despite his ground-breaking and influential works in physics. Best known for his work on quantum electrodynamics (Weisstein) and the Manhattan Project (Richard Phillips), he is considered one of the most influential scientists in recent history, and is partly responsible for popularizing the sciences to the public. Despite all of his innumerable accolades, he is one of the lesser known scientists of recent history for what he accomplished. Doctor Feynman was born on the 11th of May, 1918 in Manhattan, New York, and was the son of Lucille and Melville Feynman. Both of his parents originated from Russia and Poland, as both were Ashkenazi Jews.
Joseph (Jo) Rotblat was a nuclear scientist. He helped to make the first atomic bomb. But for decades he campaigned against what he had helped unleash. Until he died last year, aged 96, he pursued this aim with the dynamism of a man half his age, inspiring others to join the cause. He was born in Poland in 1908.
He started out as a young boy, working in a print shop. He was lucky enough to retire from printing, which is when he picked up his interest in science, among other things. Finally, later in his life after he had already become famous for his experiments on electricity, he became a politician; doing anything he could to achieve freedom for the United States of America. In the following paragraphs, I will describe how these steps of Franklin’s life led him to become a very big part of the
Although Ben Franklin created the idea of electricity, electricity is used quite different today. Created in 1752, Franklin used his famous kite experiment and proved that lightning was electricity. Currently, we don’t use a kite and key to get electricity, we have electric companies that distribute it out. Admiring Ben for what he did gives people the inspiration to invent new things! Ben Franklin the person who discovered electricity will be remembered in American History.
He set out to conduct numerous experiments, developing many theories on how he could better the lives of society. "It has been felt by many people over the years that there was no United States inventor as great as Franklin until the time of Thomas A. Edison" (Blow 24). Benjamin Franklin considered his efforts to be a part of "his civic duties" (Franklin). He states his attitude toward his inventions by asking the question, "What signifies Philosophy that does not apply to some use?" (Fleming 21).
