Outcome 3b of the Engineering Criteria of 2000, states that engineering graduates must have “an ability to design and conduct experiments, as well as to analyze and interpret data”. Engineers typically perform one of three types of experiments: a. A theoretical relationship between two or more variables is already known (or at least suspected) and an experiment is needed to verify or quantify this relationship. b. A theoretical relationship between two or more variables is not available but…

Reflection essay #4 Our discussion about relationship between creativity and spatial reasoning reminds me of a study of “Mozart effect” (Rauscher et al. 1993), which showing that music by Mozart can temporary improves experimental subjects’ spatial reasoning ability comparing to the control group. Of course, the study is not promoting Mozart’s work. Some recent work shows that the music with seizure frequencies close to the working frequencies of brain can help with stimulating brain activity.…

The Infinity POM By: Vinayak Prathikanti, Varun Popli, & Alan Xiao For the second month, we had the Infinity POM, and it definitely made us think a little. The problem said to consider all of the infinite numbers between 0 and 1, then all of the numbers on the number line. Which one of these is the larger infinity? Now before we say anything else, we want to tell you that this is an extremely open ended problem, and that it is very hard to argue one side. While this is true, we…

1. What is the shape of Ebbinghaus’s Classic forgetting curve, and what does it tell us about memory? Ebbinghaus’s Classic forgetting curve is shaped like a curved letter L (T. Hanson. Brain and Behavior). It tells us that the sooner we rehearse new information after learning it, the better the likelihood that we will remember it. However, the more time that passes, the less able we will be to remember all of the information and it only takes a few minutes for much of the information to become…

In this paper, I will attempt to explain Peter Singer’s position on “Effective Altruism. I will then argue that there is a problem with one of his claims. I will also give examples and statistics to back up my argument or objection to one of his claims. Once I am done giving my objection, I will then summarize everything in my paper and give my final take on Peter Singer’s view on Effective Altruism. At the end of the paper, the audience will be able to identify my views and see what I believe…

This article was granted as an escort for developing quantitative studies and preparing quantitative manuscripts for publication in counseling journals (Trusty, 2011, p. 261). Trusty (2011) mentioned that this article was “intended as an aid for aspiring authors in conceptualizing studies and formulating valid research designs” (p. 261). Information was conferred on choosing variables, measures, and on indicating statistical analyses paradigms. The subsequent portion of the article discloses…
