Biographical Essay Assignment 10136 최하늘 Richard Feynman Richard Feynman is well-known as a quantum physicist which deals with the most difficult subject of the modern physics. In order to break public’s view of the subject that is difficult, he made a new diagram about the activity of photoelectric particles which could be easily understood. Feynman’s research career was made through his diligence to constantly cope with questions he had toward quantum electrodynamics, spaceship engineering and military warfare engineering. He started his own research by having curiosity about simplifying earlier academic papers written by Bohr, Einstein, and Heisenberg. Feynman’s endless intellectual curiosity was heavily influenced by his father, Melville …show more content…

Sometimes environment those around him refused to answer his questions, but he did not give up asking. He joined the investigation committee of the Space Shuttle Challenger disaster though he was seriously ill due to irradiation during Manhattan project, and found out the root cause by having questions about elastic force of the rubber packing band called O-ring. Because of low temperature, the elastic force of O-ring decreased, and it caused the explosion of spaceship. During the public hearing, he did a simple experiment with ice water and a rubber band to simply show O-ring’s problem at the low temperature. In Appendix F – Personal Observations on the Reliability of the Shuttle, Feynman points out the base of his question – erosion, “The O-rings of the Solid Rocket Boosters were not designed to erode. Erosion was a clue that something was wrong” (NASA, 1). This simple experiment which started by his mere curiosity affected public’s critics and made NASA answer details of the disaster. James Gleick, the author of Chaos, states in his New York Times article about Feynman’s experiment, “It was a turning point in the investigation - a simple experiment, taking half a minute and no money, that perfectly demonstrated both the vulnerability of the seal and the absolute confidence of the experimenter” (Gleick,

Jonathan Edward Dick appeared in court on September 1, 2020, before this Court, and pleaded not guilty to the three offences included in the filed indictment. These accusations included his brother David Andrew Dick's murder on 3 February 2017, David Cammarata's attempted murder witnessed by Daniel Williams on 23 August 2018, and David Cammarata's stalking between 29 July and 19 August 2019.

It is after two paragraphs exploring notions of man’s cosmic connection that Sagan asserts his first claim in the essay, “plainly there is no way back… we are stuck with science” (1). The compassionate tone persists even in assertions, as seen through the use of first person. More compassionate is the gentle acknowledgement of the pseudoscience appeal. “Yes, the world would be a more interesting place if there were UFOs lurking in the deep waters off Bermuda… or if our dreams could, more often than can be explained by chance and our knowledge of the world, accurately foretell the future” (1). This series of sentences ends the introduction.

In 1936, Phyllis Wright, a sixth-grader that hoped to understand what scientist prayed about, sent a letter to Albert Einstein, who responded to her inquiry with a well-thought-out letter. Within the reply, Einstein used appeals to logos, ethos, and pathos; clever manipulation of the relationship between subject, speaker, and audience; and a well-articulated purpose, all of which made Einstein’s reply rhetorically effective. Perhaps the most important observation that can be made about rhetoric in Einstein’s response is the clear imbalance of the rhetorical triangle, which describes the relationship between subject, audience, and speaker. The subject addressed within Einstein’s letter was prayer and how scientists use it, and this subject clearly
