Almost all of the material phenomena which occur under terrestrial conditions are recognized as quantum mechanical consequences of the electrical attraction between electrons and nuclei and of the gravitational attraction between massive objects. We should be able, therefore, to express all the relevant magnitudes which characterize the properties of matter in terms of the following six magnitudes: M, m, e, c, G, and h; M is the mass of the proton, m and e are the mass and electrical charge of the electron, c is the light velocity, G is Newton's gravitational constant, and-most importantly-h is the quantum of action ...

I must now explain what I mean by the quantity of action. A certain action is necessary for the carrying of a body from one point to another: this action depends on the velocity which the body has and the space which it describes; but it is neither the velocity nor the space taken separately. The quantity of action varies directly as the velocity and the length of path described; it is proportional to the sum of the spaces, each being multiplied by the velocity with which the body describes it. It is this quantity of action which is here the true expense (dépense) of nature, and which she economizes as much as possible in the motion of light.

This ideal University of Life ... would never take the importance of culture for granted. It would know that culture is kept alive by a constant respectful questioning-not by an excessive and snobbish attitude of respect. Therefore, rather than leaving it hanging why one was reading Anna Karenina or Madame Bovary, an ideal course covering nineteenth-century literature would ask plainly "What is it that adultery ruins in a marriage?” Students in the ideal University of Life would end up knowing much the same material as their colleagues in other institutions, they would simply have learned it under a very different set of headings.

An essential distinction exists between two stages in the process of advancing our knowledge of the laws of physical phenomena; the first stage consists in observing the relations of phenomena, whether of such as occur in the ordinary course of nature, or of such as are artificially produced in experimental investigations, and in expressing the relations so observed by propositions called formal laws. The second stage consists in reducing the formal laws of an entire class of phenomena to the form of a science; that is to say, in discovering the most simple system of principles, from which all the formal laws of the class of phenomena can be deduced as consequences.

Compassion for other human beings has to extend to the society that's been grinding the powerless under its heel. The more civilized the society becomes, the more humane it becomes; the more it can see its own humanity, the more it sees the ways in which its humanity has been behaving inhumanly. This injustice of the world inspires a rage so intense that to express it fully would require homicidal action; it's self-destructive, destroy-the-world rage. Simply put, I've learned that I must find positive outlets for anger or it will destroy me. I have to try to find a way to channel that anger to the positive, and the highest positive is forgiveness.

The main result reached by the new theory was that the classical mechanics can be made to account for the whole range of spectral phenomena, provided entirely new meanings are given to such symbols as p and q which had hitherto been taken to describe the position and motion of the electron. ...The most significant of the new properties is that the product pq is no longer the same as the product qp - in other words the order in which the two factors are multiplied together is no longer a matter of indifference. The difference between pq and qp is found to be always the same, being Planck's constant h multiplied by a numerical multiplier.
