Why can stars do better than the big bang? ...During the big bang, there were only a few minutes when nuclei could form. Very rare processes, or slow ones, played little role. A case in point is the key process from which the sun derives its energy. In this reaction, two protons collide to produce a deuterium nucleus, a neutrino, and a positron. ...This reaction belongs to the family of weak interactions. ...It remains... a remarkable-and for humanity, remarkably fortunate-circumstance that the central reaction that drives the sun is so rare. It is only this extraordinary rarity that allows the average proton in the sun to last so long, billions of years, even though it is colliding with other protons millions of times a second. ...an entertaining example of Treiman's theorem.

Sam Treiman... has quoted something he called Treiman's theorem... Impossible things usually don't happen. ...With the discovery of radioactivity... it suddenly became apparent that the "impossible" was happening all the time. Uranium, thorium, radium... fit all the requirements of chemical elements. They could not be broken down by any of the standard methods... But occasionally... atoms of these elements spontaneously changed into other kinds of atoms. ...So what is left of the doctrine of the elements? Is alchemy reinstated? Not at all. The point is that the doctrine fails only under rare or special conditions. ...We can isolate the conditions in which they do, and retain a more restricted but still useful concept of the "impossible."

He was an extraordinary bloke. First of all he was very funny. He was straight but very camp. [He] came in and Visconte said, ‘Right, what are we doing?'. He said: ‘Well I haven't got any material, I've just got one guitar riff'. So he played us this guitar riff. It sounded a bit like Chuck Berry to me but I didn't say anything. He went out with the band and after two hours he said, ‘Right, got a song'. So we recorded it and took a few takes. He then said, ‘Right I've got a bit of a tune, just give me half an hour'. In 10 minutes he came back and said, ‘Right I've got the lyrics and got the tune'. So he'd written Get It On in 10 minutes basically. He went out there, sang it and in four or five takes we'd got it. There it was. The guy was absolutely astonishing.

Writers after Coase have referred to the authority structure of the firm as a "visible hand" that works in combination with Smith's invisible hand. The everyday fact that employers exercise power over their employees - not news to most employees - had been a central theme in Marx's economics, but it was (and generally continues to be) overlooked by most neoclassical economists. Early in his studies Coase noted the similarity between the hierarchical organization of capitalist firms, with their reliance on command relations, and the then-existing system of centralized economic planning in the Communist countries, where production was carried out in accordance with orders from higher authorities and where market competition played little role.

The life force that pulsates in the trees, plants, and animals is the same life force that pulsates within us. The same life energy that gives us the power to speak and to sing, is the power behind the song of the bird and the roar of the lion. The same consciousness that flows in and through every human being, lends its power to the movement of the wind, to the flow of the river, and to the light of the sun. How can there be any sense of difference once this subtle principle is understood? When we evaluate our growth and development in the light of this great Truth, we may wonder whether we human beings have really developed or grown at all. The progress that we see today is divided growth. Only some parts are growing-the world as a whole remains unhealthy. We cannot call this real progress.

With the technological revolution in the military field and the enormous organizational reconstruction of the army and navy, and now that their prime shock force is made up of rocketry, voices may quite frequently be heard asserting that this is an era of "push-button warfare" where man plays nothing but an auxiliary role. This view is wrong. Without arguing the great importance of rocketry and nuclear weapons, it is a fact that regardless of the scale, nature or method of warfare, man always played, and will go on playing, a major role in it. War will still require the participation of large masses of manpower- in one case directly in the armed struggle, in another, in war production and the comprehensive material backing of armed struggle.
