问答题No Englishman believes in working from book learning. He suspects all theories, philosophical or other. He suspects everything new and dislike it, unless he can be compelled by the force of circumstances to see that this new thing has advantages over the old. Race-experience is what he invariably depends up upon, whenever he can, whether in India, in Egypt, or in Australia. His statesmen do not consult historical precedents in order to decide what to do: they first learn the facts as they are; then they depend upon their own common sense, not at all upon their university learning or upon philosophical theories. And in the case of the English nation, it must be acknowledged that this instinctive method has been eminently successful. The last people from whom praise can be expected, even for what is worthy of all praise, are the English. A new friendship, a new ideal, a reform, a noble action, a wonderful poet, an exquisite painting—any of these things will be admired and praised by every other people in Europe long before you can get Englishmen to praise. The Englishman all this time is studying, considering, trying to find fault. Why should he try to find fault? So that he will not make any mistakes at a later day. He has inherited the terrible caution of his ancestors in regard to mistakes. It must be granted that his caution has saved him from a number of very serious mistakes that other nations have made. It must also be acknowledged that he exercises a fair amount of moderation in the opposite direction—this modern Englishman; he has learned caution of another kind, which his ancestors taught him. "Power should be used with moderation: for whoever finds himself among valiant men will discover that no man is peerless." And this is a very important thing for the strong man to know-that however strong, he cannot be the strongest; his match will be found when occasion demands it. Not only Scandinavian but English rulers have often discovered this fact to their cost.

问答题Doing a PhD is certainly not for everybody, and I do not recommend it for most people. However, I am really glad I got my PhD rather than just getting a job after finishing my Bachelor's. The number one reason is that I learned a hell of a lot doing the PhD, and most of the things I learned I would never get exposed to in a typical software engineering job. (1) The process of doing a PhD trains you to do research, to read research papers, to run experiments, to write papers, to give talks. It also teaches you how to figure out what problem needs to be solved. You gain a very sophisticated technical background doing the PhD, and having your work subject to the intense scrutiny of the academic peer-review process—not to mention your thesis committee. I think of the PhD a little like the Grand Tour, a tradition in the 16th and 17th centuries where youths would travel around Europe, getting a rich exposure to high society in France, Italy, and Germany, learning about art, architecture, language, literature, fencing, riding—all of the essential liberal arts that a gentleman was expected to have experience with to be an influential member of society. Doing a PhD is similar. You get an intense exposure to every subfield of Computer Science, and have to become the leading world's expert in the area of your dissertation work. (2) The top PhD programs set an incredibly high bar. a lot of coursework, teaching experience, qualifying exams, a thesis defense, and of course making a groundbreaking research contribution in your area. Having to go through this process gives you a tremendous amount of technical breadth and depth. Some important stuff I learned doing a PhD. How to read and critique research papers. As a grad student you have to read thousands of research papers, extract their main ideas, critique the methods and presentation, and synthesize their contributions with your own research. As a result you are exposed to a wide range of CS topics, approaches for solving problems, sophisticated algorithms, and system designs. This is not just about gaining the knowledge in those papers (which is pretty important), but also about becoming conversant in the scientific literature. How to write papers and give talks. Being fluent in technical communications is a really important skill for engineers. I've noticed a big gap between the software engineers I've worked with who have PhDs and those who don't in this regard. (3) PhD-trained folks tend to give clear, well-organized talks and know how to write up their work and visualize the result of experiments. As a result they can be much more influential. How to run experiments and interpret the results: I can't overstate how important this is. A systems-oriented PhD requires that you run a zillion measurements and present the results in a way that is both bullet-proof to peer-review criticism (in order to publish) and visually compelling. Every aspect of your methodology will be critiqued (by your advisor, your co-authors, your paper reviewers) and you will quickly learn how to run the right experiments, and do it right. (4) How to figure out what problem to work on. This is probably the most important aspect of PhD training. Doing a PhD will force you to cast away from shore and explore the boundary of human knowledge. (Matt Might's cartoon on this is a great visualization of this. ) I think that at least 80% of making a scientific contribution is figuring out what problem to tackle, a problem that is at once interesting, open, and going to have impact if you solve it. There are lots of open problems that the research community is not interested in (c.f., writing an operating system kernel in Haskell) . There are many interesting problems that have been solved over and over and over (c.f. , file system block layout optimization; wireless multi hop routing) . There's a real trick to picking good problems, and developing a taste for it is a key skill if you want to become a technical leader. (5) So I think it's worth having a PhD, especially if you want to work on the hardest and most interesting problems. This is true whether you want a career in academia, a research lab, or a more traditional engineering role. But as my PhD advisor was fond of saying, "doing a PhD costs you a house. " (In terms of the lost salary during the PhD years—these days it's probably more like several houses. )

问答题 {{U}}The steadily growing number of single-person households in Britain has raised plenty of troubling issues—how to build enough dwellings to accommodate them, what to do about the decline in traditional family cohesion—to keep planners and sociologists busy{{/U}}. But one as yet unstudied side- effect of this social trend appears to be an explosion in the cat population. The Pet Food Manufacturers' Association reckons that the number of dogs has declined from a peak of 7.4 million in 1990 to 6.5 million now. (47){{U}}Meanwhile the domestic cat population has risen steadily, overtaking dog numbers in 1993 to stand now at about 8 million, twice as many as there were in 1965.{{/U}} Changing life-styles, more than anything else, are responsible for this. (48){{U}}More single-person households and more married women at work means that fewer households are able to give a dog the walks and other attention it needs{{/U}}. Cats, on the other hand, apart from daily feeding, can be left pretty much to their own devices. Which also means that they sometimes wander off in search of a better place to stay if the mood takes them. This causes another problem: feral eats. (49){{U}}As cats are harder to round up than dogs, and breed prolifically—a pair can produce ten offspring a year—large colonies of 80 or so cats hiding out in disused buildings are increasingly common{{/U}}. While the Royal Society for the Protection of Animals and the Cat Protection League re-house about 125,000 lost or unwanted cats a year, the League guesses that there may be about 1.2m wild cats in Britain. (50){{U}}If they are not a nuisance the animal charities neuter the ones they can catch and then leave them alone{{/U}}. Animal-lovers are pleased. Bird-lovers are not. They blame cats for the sharp decline in the number of small birds in Britain. The League, however, has an. idea for making wild cats socially useful. It tries to persuade farmers and garden centres to take them on as environmentally-friendly rat- catchers. A bunch of neutered, wild cats could well be an efficient way of controlling a potentially plague of rats and mice.
