To start, we will consider a single particle moving in three space dimensions under the influence of a general central potential. Later we will specialize to the case of a Coulomb potential, and work out the spectrum of hydrogen. One other classic problem, the harmonic oscillator, will be treated at the end of this chapter.

God is nearer to us than any man at every time. He is nearer to me than my raiment, nearer than the air or light, nearer than my wife, father, mother, daughter, son, or friend. I live in Him, soul and body. I breathe in Him, think in Him, feel, consider, intend, speak, undertake, work in Him.

What about the orbiting of the so-called electrons around their central nucleus? What has really been observed unequivocally? Nothing of the moving particle; what has rather been observed are phenomena which at first glance have nothing to do at all with the motion of bodies. Everything else that leads to the atomic model, is a long chain of inferences.

In general, the Church has often rendered valuable aid by joining the advanced public conscience of any period in its protest against some single intolerable evil, but it has accepted as inevitable the general social system under which the world was living at the time, and has not undertaken any thoroughgoing social reconstruction in accordance with Christian principles.

There are people who literally cannot start a project until the deadline is four hours away, even if it's a big one. And those people have a serious problem. My recommendation is set up mini-deadlines. You might say, 'Okay, here's my deadline after three days for this and there's another deadline for that and then a third deadline.

I used to say that, as Solicitor General, I made three arguments in every case. First came the one I had planned – as I thought, logical, coherent, complete. Second was the one actually presented – interrupted, incoherent, disjointed, disappointing. The third was the utterly devastating argument that I thought of after going to bed that night...
