Working on a vacuum manifold: See LLP chapter 9.2 for an excellent discussion on working with air-sensitive reagents, including how to use a two-way manifold. De-gassing solvents: The best way to remove water and oxygen from a solvent is to distill it over an appropriate drying agent (such as sodium). This can sometimes be a lengthy (and dangerous)task. Since we

November 21, 2001 Ethical Egoism Here are three questions (of course there are others)we might want an ethical theory to answer for us: i)Which acts are right and which are wrong? Which acts ought we to perform(understandir the\ought\ as moral \ought\)? ii)What makes a particular action right or wrong? What is it about the action that determines its moral status? ii)How do we know what is right and wrong? Remember that according to relativism, whether an action is right or wrong

萃取、冲洗和干燥:还没到结束不能算结束。藉由分液漏斗示 。 范液相-液相萃取并学习如何用”反应检查步骤”检查你的反应。这 是一个你不会想错失的一个纯化技巧! Extracting, Washing and Drying: It ain't over 'til it's over. Learn how to \work up\ your reaction using a separatory funnel to perform a liquid-liquid extraction. This is one purification technique you don't want to miss!

Introduction This lesson will address questions related to different levels of government: How should various responsibilities be allocated to different levels of government? Is decentralized government decision making desirable? Are locally raised taxes a good way to pay for services provided locally?

Political Economy Defined Political Economy is the application of economic principles to the analysis of political decision making. -elf- -interestin- the marketplace, this often leads to efficiency; different implications in \political market. Maximization-one goal may be to maximize social welfare

Moral Luck One of the important themes in the freewill debate is the idea that freedom is necessary for moral responsibility. In effect, if hard determinism is the correct view, then we should not hold ourselves or others morally responsible. Libertarians, in particular, seem to hold that in order to be responsible for an act, we must be its \sole author. Here is the principle at issue: Control Principle: You are only responsible for what you have control over. If you steal an axe from my garage and use it to break into a gas station, there's no point in holding me responsible, I didn't

A pendulum is a rigid body suspended from a fixed point (hinge) which is offset with respect to the body's center of mass. If all the mass is assumed to be concentrated at a point, we obtain the idealized simple pendulum. Pendulums have played an important role in the history of dynamics. Galileo identified the pendulum as the first example of synchronous motion, which led to the first successful clock developed

In the previous lecture, we related the motion experienced by two observers in relative translational motion with respect to each other. In this lecture we will extend this relation to our third type of observer.That is, observers who accelerate and rotate with respect to each other. As a matter of illustration, let us consider a very simple situation, in which a particle at rest with respect

Gene mutation and evolution Gradual accumulation of mutations over long periods of time results in new biological species, each with a unique DNA sequence. Mutations and stabilization of mutations to new species. Charles Darwin: Unifying evolution theory-the origin of species from a common ancestor
