ABOUT
IU. Extra Credit: This problem is about a process called the one-point compactification of a non-compact space. This is sometimes called the Alexandroff one-point compactifica- tion. The general idea is that you can sometimes add a single point to a non-compact 2 space and get a space that is compact: a) On the last homework set, you explored the stereographic projection map f S2-NR2....

This week we study how consumers make decisions to maximize their benefit (most satisfaction, biggest "bang for a buck"). But what if decisions are made for us as it is the case with gifts? Do gifts maximize our benefit? Is there more to gifts than just monetary value? Earlier this week, Waldfogel was at it again in a webcast for members of the media that was sponsored by the National Science Foundation. Here is just some of his math: Americans...

How to properly solve these elimination and addition
reactions
Elimination and Addition reactions Purpose: Figuring out the ways that molecules react is the province of the mechanistic chemist. By understanding the mechanisms of reactions, the chemist can manipulate the experimental variables to favor one product over another. This element of control is the province of the synthetic organic chemist. This Workshop continues to explore how we know how molecules react and how this knowledge leads to control of the products....

Sunshine Enterprises Case Study “I think the waiter wrote in an extra $25 tip on my Sunshine Café bill after I received and signed my credit card receipt,” Mr. Mark Otter said to the restaurant manager, Brad Gladiolus. “Mr. Otter, mail me a copy of the restaurant receipt and I’ll investigate,” responded Mr. Gladiolus. “I don’t have the receipt—I lost it—but I have my monthly credit card statement,” replied Mr. Otter. Mr. Gladiolus hesitated, then said, “Mr. Otter, I don’t...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....

FISCAL POLICY IN THEORY: March, 2020: we are on the verge of Congress and the President passing legislation that will empower the federal government to spend an unprecedented amount of EXTRA money not seen since World War 2 ---- in order to address the pandemic but also to help cushion the blow financially of perhaps ten or twenty million Americans --- or more --- losing their jobs, and thus suffering a drop in income. The scale of the 2020 recession...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
