PHY102 week 1 discussion (dq1+dq2) latest 2018 july

Week 1 discussion

DQ1 The reading for this week includes the following statement: "It is emphasized that scientists, through their investigations, do not prove anything" (GCU, 2014). A similar statement was made in an open letter to the editor of Science: "There is always some uncertainty associated with scientific conclusions; science never absolutely proves anything" (Glieck et al., 2010). While technically true when considering the scientific method, it may be more beneficial to employ a graduated approach by classifying scientific information as "proven, evolving, [or] borderline science" (Moghissi, Amin, & McNulty, 2010).

Read "Does Science Never Absolutely Prove Anything?" by Moghissi, Amin, and McNulty. Then consider the theory of evolution. Do you consider the theory of evolution proven, evolving, or borderline science? Support your answer.

DQ2 In this Topic, you have learned the terms used to describe motion (e.g., distance, speed, and acceleration) as well as Newton's laws explaining motion. Describe at least two ways the material you have learned in this unit applies to driving a car (refer to the Arizona Driver License Manual located within the weekly readings). Has what you have learned in this Topic changed how you drive? If so, please explain.
