Early Modern England: Politics, Religion, and Society under the Tudors and Stuarts (HIST 251)Professor Wrightson discusses local particularism and regionalism in early modern England and highlights the importance of local customs and economic patterns. He then focuses on the manner in which these local areas, while enjoying a measure of cultural, institutional, and economic autonomy, were simultaneously integrated into a larger national wh...more

Komisar warns against the concept of a deferred life plan, when people put off what they really want to do for what is expected of them. According to Komisar, this is when you are deferring your sense of excitement and passion for what you really care about. Working hard is not inconsistent with the deferred life plan, he adds, but doing so for a product that you do not have interest in is.

Komisar believes there is evidence of new bubbles occurring in certain industries today, specifically in Web 2.0. The good news is that there are also many other industries, such as those in energy, life sciences, and healthcare, where bubbles are absent. He also gives advice on whether companies should seek institutional financing or professional investments.

Acetic Acid to Acetyl Chloride mechanism. Can be generalized to forming any acid halide from a carboxylic acid.
-
Professor Sylvia Ceyer discusses the classification of acids and bases as they are defined by Arrhenius, Bronsted-Lory, and Lewis acid/base. The pH function (and pOH function) are defined as they relate to the strength of acids and bases (in water). Professor Ceyer then runs through the types of acid-base problems and concludes by discussing equilibrium involving weak acids.
-
Professor Sylvia Ceyer continues her discussion of acid-base equilibrium, diving into buffers. The lecture concludes with the Henderson-Hasselbalch equation and its use in designing a buffer.
-
Professor Sylvia Ceyer discuses titrations involving a strong acid and a strong base. Defining the point and equivalence and the end point. The lecture continues with a focus on calculating points on a pH curve, specifically calculating pH before the equivalence point, calculating volume of HCl needed to reach equivalence point, and calculating pH after the equivalence point. Finally, Professor Ceyer discusses characteristics of titratio...more
