Planck's quantization assumption applied to the matter that emits and absorbs radiation, not to radiation itself. As George Gamow later remarked, Planck thought that radiation was like butter; butter itself comes in any quantity, but it can be bought and sold only in multiples of one quarter pound. It was Albert Einstein (1879–1955) who in 1905 proposed that the energy of radiation of frequency ν was itself an integer multiple of hν.

Symons ... remarked that the most common and unhelpful illusion plaguing those who came to see him was the idea that they ought somehow, in the normal course of events, to have intuited-long before they had finished their degrees, started families, bought houses and risen to the top of law firms-what they should properly be doing with their lives. They were tormented by a residual notion of having through some error or stupidity on their part missed out on their true calling.

To renew the energy expended in physical labour, the worker must be provided with the requirements of his existence as a functioning organism-food, clothing, and shelter for himself and his family. The labour time socially necessary to produce the necessities of life of the worker is the value of the worker's labour power. The latter's value is, therefore, reducible to a specifiable quantity of commodities: those which the worker requires to be able to subsist and reproduce.

God, Satan, Paradise, and Hell all vanished one day in my fifteenth year, when I quite abruptly lost my faith. ... and afterwards, to prove my new-found atheism, I bought myself a rather tasteless ham sandwich, and so partook for the first time of the forbidden flesh of the swine. No thunderbolt arrived to strike me down. ... From that day to this I have thought of myself as a wholly secular person.

I believe in you and me. I'm like Albert Schweitzer and Bertrand Russell and Albert Einstein in that I have a respect for life -- in any form. I believe in nature, in the birds, the sea, the sky, in everything I can see or that there is real evidence for. If these things are what you mean by God, then I believe in God. But I don't believe in a personal God to whom I look for comfort or for a natural on the next roll of the dice.

Wisdom: The first error is that of the southern people, and it consists in holding that these eastern and western places are real places. ... give no quarter to that thought, whether it threatens you with fear, or tempts you with hopes. For this is Superstition and all who believe it will come in the end to the swamps to the south and the jungles to the far south. Part of the same error is to think that the Landlord is a real man:.
