1-1 What Macroeconomists Study Why have some countries experienced rapid growth in incomes over the past century while others stay mired in poverty? Why do some countries have high

Intensive Study Marriage Across the Nations Para. 1 Gail and I imagined quiet wedding. During our two years together we had experienced the usual ups and downs of a couple learning to know, understand, and respect each other. But through it all we had honestly confronted the

Carbon atoms have the ability to link together and form molecules made up of many carbon atoms. The branch of chemistry that is the study of carbon-containing compounds is known as organic chemistry(有机化学) 13 million known organic compounds and 100,000 new ones are added annually Only 200,000-300,000 known inorganic compounds

In the chapter we shall study the properties of second-order circuits, i.e., circuits containing two energy-storage elements. Such circuits will, in general, be characterized by second-order differential equations

In the chapter we shall introduce the study of circuits characterized by a single energy-storage element--a capacitor or a inductor. It will be shown that the equations describing such a circuit may be put in a form involving an unknown variable and its first derivative. Such an equation is referred to as a first-order differential equation, thus we shall refer to circuits which contain only a single energy-storage element as first-order circuits

Intensive Study There's a Lot More to Life than a Job Para.1 It has often been remarked that the saddest thing about youth is that it is wasted on the young. Para. 2 Reading a survey report on first-year college students, I recalled the regret, \If only knew then what know now

In this course we will study Classical Mechanics. Particle motion in Classical Mechanics is governed by Newton's laws and is sometimes referred to as Newtonian Mechanics. These laws are empirical in that they combine observations from nature and some intuitive concepts. Newton's laws of motion are not self evident. For instance, in Aristotelian mechanics before Newton, force was thought to be required in order
