# UC Merced Motion of Cyclotrons Around the Sun Worksheet

UC Merced Motion of Cyclotrons Around the Sun Worksheet.

Show how to derive the expression r = mv/qB for the cyclotron radius of a charged
particle moving in a circular path perpendicular to a uniform magnetic
field, starting with Newton’s 2nd Law.
The Sun’s magnetic field is typically around 100 G, roughly 100
times stronger than the Earth’s magnetic field. (In or near sunspots and
other magnetically active regions, the Sun’s magnetic field can be even
stronger— around 0.3 T.) The temperature of the Sun’s corona (outer
atmosphere) is around 106 K, so that protons and electrons there move
with speeds of the order of 105 m/s and 107 m/s, respectively. What are
the gyro radii of these particles in the Sun’s magnetic field? How good
an approximation is it to say that these particles are “confined to move
along magnetic field lines” for excursions of the order of the distances seen in images of coronal loops and
arches taken from spacecraft (a few % of the Sun’s diameter)? What do such images tell us about the Sun’s magnetic field?

## John Snow The Father Of Epidemiology History Essay

John Snow (1813-1858), the father of epidemiology, has a legacy that still exists today. His use of epidemiological methods helped identify the risks of certain diseases and has also helped establish what preventative actions should be taken in response to an outbreak. He was a great man that is known for his work involving anesthesia and cholera. In Snow’s short lifetime, Oleckno claims (2008), “He is credited with writing over 100 books, pamphlets, essays, articles, and letters to the editor on a variety of medical topics”(p.1691) including his very famous book, On the Mode of Communication of Cholera, which describes the cholera outbreak that took place in Soho in 1854 (Oleckno, 2008, p. 1691). Snow’s studies have shaped the world’s views on epidemiology as a science, and they have changed the way we confront public health problems that still exist today. Snow’s experiments provided a perfect example of this science since epidemiology is concerned with who gets sick, and why they get sick. Research by Blank and Jameson (2007) proves that, “Snow’s work still serves as an example of how prevention can be effective without an explicit understanding of the exact mechanism of underlying pathogenesis” (p. 3). Although his ideas were highly debatable at the time when it came to the spread of cholera, Snow still pressed on and eventually got his point across. Through his hard work and persistent determination, John Snow is seen as a pioneer who brought the use of anesthesia out of the dark ages, and a savior who contributed to rescuing London from the terrors that cholera produced (Oleckno, 2008, p 1692). Snow was born on March 15, 1813 to a working class family in York, England. As a young boy, Snow proved that he was very bright. He particularly excelled in mathematics. His mother recognized his intelligence and eagerness to learn, so she placed him in a private school where he could shine. Snow had a desire to become a doctor, and when he was fourteen he attained an apprentice job alongside Dr. William Hardcastle, a pharmacist, in Newcastle-upon-Tyne (Old News, 2005, p. 8). Hardcastle exposed Snow to cholera patients during an outbreak in Killingworth in 1832, effectively giving him a medical understanding. In 1836, Snow entered the Hunterian School of Medicine in London. While in school, he also gained more clinical experience at the Westminster Hospital. In 1843 he received his bachelor of medicine, and in 1844 he graduated as a MD from The University of London (Simmons, 2002, p. 163). At this time, and for his lifetime, John Snow was described as a modest bachelor who was very healthy. He followed a strict vegetarian diet since the age of seventeen (Mawson, 2009, p. 498), and he abstained from drinking alcohol. On occasion, he would even publicly support temperance. John Snow lived in Soho, London on Frith Street. After moving to Soho, Snow distinguished himself by making the first scientific studies on the effects of anesthetics. He focused most of his scientific experiments on the usage of ether and chloroform. According to Hempel (2007) Snow, “Was looking for the perfect narcotic vapor; effective, easy to administer, and completely safe” (p. 97). Ether and chloroform are colorless, unstable, liquids that come from ethyl alcohol. They were formerly used as inhalant anesthetics. Chloroform however, was known to cause heart problems. John Snow is very interesting to me in the fact that he experimented with anesthetics on himself. He did this for nine years, and ahis goal was to identify a drug that had the properties and advantages of chloroform, but was similar to ether in not causing cardiac arrest (Mawson, 2009, p.498). Snow studied the advantages and disadvantages of each of the narcotics, and eventually he developed an anesthetic inhaler with a mouthpiece. After putting the inhaler on his face, Snow would record the dosage he was about to give himself, and then release the gas he was testing. He would fall unconscious very quickly, and would remain knocked out for different periods of time depending on the drug and the amount he was using. When he would awake, Snow would record the amount of time he was unconscious for. These tests helped determine how much a patient could handle, especially when being operated on. Because Snow made the usage of these drugs more safe and effective, surgeons no longer risked killing their patients by using the wrong amount of a certain anesthetic. Also, in 1847, Snow published a textbook entitled, On the Inhalation of the Vapour Ether in Surgical Operations. This book classified Snow as an anesthesia expert in England. Snow’s newly gained fame as becoming a pioneer in anesthetics led to his invitation to assist in delivering Queen Victoria’s children, Prince Leopold and Princess Beatrice (Oleckno, 2008, p. 1691). The mask he had invented was used to administer chloroform to Queen Victoria. It aided her while she was giving birth to her last two children. After his work in anesthetics, Snow moved on to investigating cholera. According to Codeco
