The first thing that you would worry about when things get very small is Brownian motion--everything is shaking about and nothing stays in place. How can you control the circuits then? Furthermore, if a circuit does work, doesn't it now have a chance of accidentally jumping back? If we use two volts for the energy of…
Now, it might be true that astrology is right. It might be true that if you go to the dentist on the day that Mars is at right angles to Venus, that it is better than if you go on a different day. It might be true that you can be cured by the miracle of Lourdes. But if it is true it ought to be investigated. Why? To…
What then is the meaning of the whole world? We do not know what the meaning of existence is. We say, as the result of studying all of the views that we have had before, we find that we do not know the meaning of existence; but in saying that we do knot know the meaning of existence, we have probably found the open…
Is nobody inspired by our present picture of the universe? The value of science remains unsung by singers, so you are reduced to hearing--not a song or a poem, but an evening lecture about it. This is not yet a scientific age. Perhaps one of the reasons is that you have to know how to read the music. For instance, the…
One day I'll be convinced there's a certain type of symmetry that everybody believes in, the next day I'll try to figure out the consequences if it's not, and everybody's crazy but me. But the thing that's unusual about good scientists is that while they're doing whatever they're doing, they're not so sure of…
I would like to remark, in passing, since the word "atheism" is so closely connected with "communism," that the communist views are the antithesis of the scientific, in the sense that in communism the answers are given to all the questions - political questions as well as moral ones - without discussion and without…
Marketers glibly say that the consumer is king, but in practice he's not. In the real world, experienced marketing and consumer-affairs hands will tell you, consumers aren't very good at protecting their own interests. They're too busy consuming, or working, or just living regular lives. The groups that claim to…
The result of the new economics is that people are often paid for their attention, implicitly or explicitly. They get to see television free in return for watching commercials. Their magazines and newspapers are subsidized or supplied free by advertisers. Nowadays bus shelters, baseball stadiums, and even those little…
While terrestrial governments are natural monopolies in their own territories, cyberspace governments compete. Terrestrial governments get overthrown when things get too bad; cyberspace governments simply lose citizens, much as a business loses customers. Former members may even go into competition with their old…
What is a market? And what does it have to do with the Internet? The fashion right now, one I follow, is to think of the Internet as a living environment, a place for societies, communities, and institutions to grow--rather than as something constructed, a superhighway, for example. That leads to appropriate…
A final point briefly worth making is that the Web is a space designed to let information flow, and to create opportunities for cooperation and collaboration. It is worth asking why freer information flow is a good thing, and the answers are pretty straightforward. It is good to have the freedom to express oneself in…
It is argued - though currently the arguments are filtering only slowly into the academic literature - that folksonomies are preferable to the use of controlled, centralised ontologies [e.g. 259]. Annotating Web pages using controlled vocabularies will improve the chances of one's page turning up on the 'right' Web…
Another key factor in assessing the trustworthiness of a document is the reliability or otherwise of the claims expressed within it; metadata about provenance will no doubt help in such judgements but need not necessarily resolve them. Representing confidence in reliability has always been difficult in epistemic…
There are two important epistemological questions for Web Science. The first is what properties will future platforms need to have in order to allow as much information as possible to gravitate to the Web without imposing structure or governing theories upon it? One aim of the Web is to facilitate rational discussion…
[Matt] Mason's argument was sensible enough: Pirates aren't anti-capitalists, they're punk capitalists. "D.I.Y. encourages us to reject authority and heirarchy, advocating that we can and should produce as much as we consume," Mason writes in the opening chapter of his homage to piracy. "Since punk, this idea has been…
Your 3-year-old has declared that he and the closet are going to Asia. Asia, like America, is a concept that depends on our ability to think symbolically. America exists only because a group of people got together more than 200 years ago and decided that this great mass of land directly to the south of Canada should…
For the sediments are the materials of the most stupendous 'snowfall' the earth has ever seen. It began when the first rains fell on the barren rocks and set in motion the forces of erosion. It was accelerated when living creatures developed in the suface waters and the discarded little shells of lime or silica that…
So everyone agrees these days: Hooray for pirates! Art and culture (or, more discouragingly, "content") should be free. Techno-utopians of the left and right envision a future in which everything ever made is accessible, at no cost, with a click of a button. Those who think "free" as in speech envision a new digital…
The shift of the digital frontier from the Web, where the browser ruled supreme, to the smart phone, where the app and the pricing plan now hold sway, signals a radical shift from openness to a degree of closed-ness that would have been remarkable even before 1995. In the U.S., there are only three major cell-phone…
'Evolution doesn't view earth's history as a conflict between good and evil. It does essentially view it as a conflict between life and death, between increased organization and more efficient energy use on the part of life, and an opposing tendency of nonliving matter to become disorganized and lose energy--entropy…
