This is a quantum universe, neither random nor determined. It is potential at every second. All you can do is intervene.

The history of the human race has generated several papers articulating basic moral imperatives, or fundamental principles, of human coexistence that (maybe in association with concurring historical events ) substantially influenced the fate of humanity on this planet. Among these historic documents, the Universal Declaration of Human Rights, adopted fifty years ago today, holds a very special, indeed, unique position. It is the first code of ethical conduct that was not a product of one culture, or one sphere of civilization only, but a universal creation, shaped and subscribed to by representatives of all humankind. Since its very inception, the Declaration has thus represented a planetary, or global commitment, a global intention, a global guideline. For this reason alone, this exceptional document, conceived as a result of a profound human self-reflection in the wake of the horrors of World War ii, and retaining its relevance ever since, deserves to be remembered today.

If I say [electrons] behave like particles I give the wrong impression; also if I say they behave like waves. They behave in their own inimitable way, which technically could be called a quantum mechanical way. They behave in a way that is like nothing that you have seen before.

Natural objects, for example, must be experienced before any theorizing about them can occur. Experiencing is consciousness that intuits something and values it to be actual; experiencing is intrinsically characterized as consciousness of the natural object in question and of it as the original: there is consciousness of the original as being there "in person."

The technologies which have had the most profound effects on human life are usually simple. A good example of a simple technology with profound historical consequences is hay. Nobody knows who invented hay, the idea of cutting grass in the autumn and storing it in large enough quantities to keep horses and cows alive through the winter. All we know is that the technology of hay was unknown to the Roman Empire but was known to every village of medieval Europe. Like many other crucially important technologies, hay emerged anonymously during the so-called Dark Ages. According to the Hay Theory of History, the invention of hay was the decisive event which moved the center of gravity of urban civilization from the Mediterranean basin to Northern and Western Europe. The Roman Empire did not need hay because in a Mediterranean climate the grass grows well enough in winter for animals to graze. North of the Alps, great cities dependent on horses and oxen for motive power could not exist without hay. So it was hay that allowed populations to grow and civilizations to flourish among the forests of Northern Europe. Hay moved the greatness of Rome to Paris and London, and later to Berlin and Moscow and New York.

The speed of the ball, thanks to opposition from the air, will not go on increasing forever. Rather, what will happen is seen in bodies of very little weight falling through no great distance; I mean, a reduction to equable motion, which will occur also in a lead or iron ball after the descent of some thousands of braccia. This bounded terminal speed will be called the maximum that such a heavy body can naturally attain through the air.

Now one may ask, "What is mathematics doing in a physics lecture?" We have several possible excuses: first, of course, mathematics is an important tool, but that would only excuse us for giving the formula in two minutes. On the other hand, in theoretical physics we discover that all our laws can be written in mathematical form; and that this has a certain simplicity and beauty about it. So, ultimately, in order to understand nature it may be necessary to have a deeper understanding of mathematical relationships. But the real reason is that the subject is enjoyable, and although we humans cut nature up in different ways, and we have different courses in different departments, such compartmentalization is really artificial, and we should take our intellectual pleasures where we find them.

I'm interested in truth, I like science. But truth's a menace, science is a public danger. As dangerous as it's been beneficent. It's curious to read what people in the time of Our Ford used to write about scientific progress. The seemed to imagine that it could go on indefinitely, regardless of everything else. Knowledge was the highest good, truth the supreme value; all the rest was secondary and subordinate. True, ideas were beginning to change even then. Our Ford himself did a great deal to shift the emphasise from truth and beauty to comfort and hapiness. Mass production demanded the shift. Universal happiness keeps the wheels steadily turning; truth and beauty can't. And, of course, whenever the masses seized political power, then it was happiness rather than truth and beauty that mattered. Still, in spite of everything, unrestricted scientific resarch was still permitted. People still went on talking about truth and beauty as though they were sovereign goods. Right up to the time of the Nine Years'War. That made them change their tune all right. What's the point of truth or beauty or knowledge when the anthrax bombs are popping all around you? That was when science first began to be controlled, after the Nine Years'War. People were ready to have even their appetites controlled then. Anything for a quiet life. We've gone on controlling ever since. It hasn't been very good for truth, of course. But it's been very good for happiness. One can't have something for nothing. Happiness has got to be paid for.

O, what nowadays does science not conceal! How much, at least, it is meant to conceal!

The new mathematics is a sort of supplement to language, affording a means of thought about form and quantity and a means of expression, more exact, compact, and ready than ordinary language. The great body of physical science, a great deal of the essential facts of financial science, and endless social and political problems are only accessible and only thinkable to those who have had a sound training in mathematical analysis, and the time may not be very remote when it will be understood that for complete initiation as an efficient citizen of the great complex world-wide States that are now developing, it is as necessary to be able to compute, to think in averages and maxima and minima, as it is now to be able to read and write.
