Try to imagine what the electric and magnetic fields look like at present in the space of this lecture room. First of all, there is a steady magnetic field; it comes from the currents in the interior of the earth - that is, the earth's steady magnetic field. Then there are some irregular, nearly static electric fields…
Why should it be hard for scientists to get science across? Some scientists, including some very good ones, tell me they'd love to popularize, but feel they lack talent in this area. Knowing and explaining, they say, are not the same thing. What's the secret? There's only one, I think: don't talk to the general…
A few weeks before the debates, however, they are informed that it is the task of each to present the point of view of the opponent in a way that's satisfactory to the opponent - so the opponent will say, 'Yes, that's a fair presentation of my views.' In the joint written debate they explore their differences, but…
Thomas Jefferson was a scientist. That's how he described himself. When you visit his home at Monticello, Virginia, the moment you enter its portals you find ample evidence of his scientific interests - not just in his immense and varied library, but in copying machines, automatic doors, telescopes and other…
Declaration of Independence puts it - 'the laws of nature and of nature's GOD'. Dr Benjamin Franklin was revered in Europe and America as the founder of the new field of electrical physics. At the Constitutional Convention of 1789 John Adams repeatedly appealed to the analogy of mechanical balance in machines; others…
Both scepticism and wonder are skills that need honing and practice. Their harmonious marriage within the mind of every schoolchild ought to be a principal goal of public education. I'd love to see such a domestic felicity portrayed in the media, television especially: a community of people really working the mix…
In science we may start with experimental results, data, observations, measurements, 'facts'. We invent, if we can, a rich array of possible explanations and systematically confront each explanation with the facts. In the course of their training, scientists are equipped with a baloney detection kit. The kit is…
The authors comment that from this perspective, it could be stated that multiccellular beings are also ecosystems. That is, we are formed by different types of cells that cooperate and compete for resources; we are colonized by diverse types of bacteria (in the intestines, in the skin, etc.) whose activity is linked…
It is clear, however, that the cause of homosexuality lies in some unusual balance of hormonal influence in the womb but not later on, a fact that further supports the idea that the mentality of sexual preference is affected by prenatal sex hormones. This is not incompatible with the growing evidence that…
There are five ways to find out. One is to study modern people directly and describe what they do as the human mating system The answer is usually monogamous marriage. A second way is to look at human history and divine from our past what sexual arrangements are typical of our species. But history teaches a dismal…
There's obviously different kinds of programming. Without people who are not like me none of this would exist. But I've always seen much more in common with writing prose than math. It feels like you're writing a story and you're trying to express a concept to a very dumb person-the computer—who has a limited…
If you give two programmers the same problem—it depends on the problem, but problems of a more mathematical nature, they can often end up writing the same code. Subject to just formatting issues and relabeling the variables and the function names, it's isomorphic—it's exactly the same algorithms. Are we creating these…
John Washbrook, who was himself a senior academic in the department, took me under his wing and he told me something that very important. He said, "Just start something, no matter how humble." This is not recall; about programming, this is about research. But no matter how humble and unoriginal and unimportant it may…
Seibel: Do you feel like programmers and computer scientists are aware enough of the history of our field? It is, after all, a pretty short history. Knuth: There aren't too many that are scholars. Even when I started writing my books in 1963, I didn't think people knew what had happened In 1959. I was reading in…
In other words, there's still so much more beyond any five pages of my book that you can make a lifetime's worth of study, because there's just that much In computer science. Computer science doesn't all boil down to a bunch of simple things. If it turned out that computer science was very simple, that all you needed…
The problem being the old saying in the business: "fast, cheap, good—pick any two." If you build things fast and I you have some way of building them inexpensively, it's very unlikely that they're going to be good. But this s|s school of thought says you shouldn't expect software to last. I think behind this perhaps…
Often, reading about famous people, the side of it that I'm interested in is, how do they make their life work? All the things that weren't their passion, and how did they deal with that and with their family, and with their finances, and balancing that Or did they just hole up and say, "To hell with everything else,"…
think the lack of reusability comes in object-oriented mguages, not in functional languages. Because the problem with object-oriented languages is they've got all this implicit environment that they carry around with them. Vou i wanted a banana but what you got was a gorilla holding the banana and the entire jungle…
4- As an example, consider the practice of mathematics. Mathematics is in the first place a language in which we discuss those parts of the real world which can be described by numbers or by similar relations of order. But with the workaday business of translating the facts into this language there naturally goes, in…
So proud men have thought, in all walks of life, since Giordano Bruno was burned alive for his cosmology on the Campo de' Fiori in 1600. They have gone about their work simply enough. The scientists among them did not set out to be moralists or revolutionaries. William Harvey and Huygens, Euler and Avogadro, Darwin…
