Lectures Quotes

“Vladimir Nabokov“... one cannot read a book: one can only reread it. A good reader, a major reader, an active and creative reader is a rereader. And I shall tell you why. When we read a book for the first time the very process of laboriously moving our eyes from left to right, line after line, page after page, this complicated physical work upon the book, the very process of learning in terms of space and time what the book is about, this stands between us and artistic appreciation. When we look at a painting we do no have to move our eyes in a special way even if, as in a book, the picture contains elements of depth and development. The element of time does not really enter in a first contact with a painting. In reading a book, we must have time to acquaint ourselves with it. We have no physical organ (as we have the eye in regard to a painting) that takes in the whole picture and can enjoy its details. But at a second, or third, or fourth reading we do, in a sense, behave towards a book as we do towards a painting. However, let us not confuse the physical eye, that monstrous achievement of evolution, with the mind, an even more monstrous achievement. A book, no matter what it is - a work of fiction or a work of science (the boundary line between the two is not as clear as is generally believed) - a book of fiction appeals first of all to the mind. The mind, the brain, the top of the tingling spine, is, or should be, the only instrument used upon a book.” ― Vladimir Nabokov, Lectures on Literature”

“Turing attended Wittgenstein's lectures on the philosophy of mathematics in Cambridge in 1939 and disagreed strongly with a line of argument that Wittgenstein was pursuing which wanted to allow contradictions to exist in mathematical systems. Wittgenstein argues that he can see why people don't like contradictions outside of mathematics but cannot see what harm they do inside mathematics. Turing is exasperated and points out that such contradictions inside mathematics will lead to disasters outside mathematics: bridges will fall down. Only if there are no applications will the consequences of contradictions be innocuous. Turing eventually gave up attending these lectures. His despair is understandable. The inclusion of just one contradiction (like 0 = 1) in an axiomatic system allows any statement about the objects in the system to be proved true (and also proved false). When Bertrand Russel pointed this out in a lecture he was once challenged by a heckler demanding that he show how the questioner could be proved to be the Pope if 2 + 2 = 5. Russel replied immediately that 'if twice 2 is 5, then 4 is 5, subtract 3; then 1 = 2. But you and the Pope are 2; therefore you and the Pope are 1'! A contradictory statement is the ultimate Trojan horse.”

“Besides what endless brawls by wives are bred,The curtain lecture makes a mournful bed.”

“Thousands of persons, many of whom never darkened the door of a college, have learned to read books that most of our college graduates fear to tackle. teachers who understand this fact can help a student read the books that educated the Founding Fathers but not by explaining in lectures what the author would have said if he had been as bright as the lecturer.”

“We must never forget our teachers, our lecturers and our mentors. In their individual capacities have contributed to our academic, professional and personal development.”

“[Benjamin Peirce's] lectures were not easy to follow. They were never carefully prepared. The work with which he rapidly covered the blackboard was very illegible, marred with frequent erasures, and not infrequent mistakes (he worked too fast for accuracy). He was always ready to digress from the straight path and explore some sidetrack that had suddenly attracted his attention, but which was likely to have led nowhere when the college bell announced the close of the hour and we filed out, leaving him abstractedly staring at his work, still with chalk and eraser in his hands, entirely oblivious of his departing class.”

“It was Daisuke's conviction that all morality traced its origins to social realities. He believed there could be no greater confusion of cause and effect than to attempt to conform social reality to a rigidly predetermined notion of morality. Accordingly, he found the ethical education conducted by lecture in Japanese schools utterly meaningless. In the schools, students were either instructed in the old morality or crammed with a morality suited to the average European. For an unfortunate people beset by the fierce appetites of life, this amounted to nothing more than vain, empty talk. When the recipients of this education saw society before their eyes, they would recall those lectures and burst out laughing. Or else they would feel that they had been made fools of. In Daisuke's case it was not just school; he had received the most rigorous and least functional education from his father. Thanks to this, he had at one time experienced acute anguish stemming from contradictions. Daisuke even felt bitter over it.”

“A few years after I gave some lectures for the freshmen at Caltech (which were published as the Feynman Lectures on Physics), I received a long letter from a feminist group. I was accused of being anti-women because of two stories: the first was a discussion of the subtleties of velocity, and involved a woman driver being stopped by a cop. There's a discussion about how fast she was going, and I had her raise valid objections to the cop's definitions of velocity. The letter said I was making the women look stupid. The other story they objected to was told by the great astronomer Arthur Eddington, who had just figured out that the stars get their power from burning hydrogen in a nuclear reaction producing helium. He recounted how, on the night after his discovery, he was sitting on a bench with his girlfriend. She said, "Look how pretty the stars shine!" To which he replied, "Yes, and right now, I'm the only man in the world who knows how they shine." He was describing a kind of wonderful loneliness you have when you make a discovery. The letter claimed that I was saying a women is incapable of understanding nuclear reactions. I figured there was no point in trying to answer their accusations in detail, so I wrote a short letter back to them: "Don't bug me, Man!”

“THE QUESTION IS, OF COURSE, IS IT GOING TO BE POSSIBLE TO AMALGAMATE EVERYTHING,AND MERELY DISCOVER THAT THIS WORLD REPRESENTS DIFFERENT ASPECTS OF ONE THING?”
