Zitat des Tages von James Gleick:
I really don't think of myself as a science writer.
Nanosecond precision matters for worldwide communications systems. It matters for navigation by Global Positioning System satellite signals: an error of a billionth of a second means an error of just about a foot, the distance light travels in that time.
I think we are always right to worry about damaging consequences of new technologies even as we are empowered by them. History suggests we should not panic nor be too sanguine about cool new gizmos. There's a delicate balance.
Novelists are in the business of constructing consciousness out of words, and that's what we all do, cradle to grave. The self is a story we tell.
Granted, I'm more interested in technology than most people, and less interested in politics than most. But I don't like to think about categories. I really see myself as a general non-fiction writer.
Despite the metadata attached to each tweet, and despite trails of retweets and 'favorite' tweets, the Twitter corpus lacks the latticework of hyperlinks that makes Google's algorithms so potent. Twitter's famous hashtags - #sandyhook or #fiscalcliff or #girls - are the crudest sort of signposts, not much help for smart searching.
In the 1920s, a generation before the coming of solid-state electronics, one could look at the circuits and see how the electron stream flowed. Radios had valves, as though electricity were a fluid to be diverted by plumbing. With the click of the knob came a significant hiss and hum, just at the edge of audibility.
The body itself is an information processor. Memory resides not just in brains but in every cell. No wonder genetics bloomed along with information theory. DNA is the quintessential information molecule, the most advanced message processor at the cellular level - an alphabet and a code, 6 billion bits to form a human being.
I'll cheerfully confess to spending a lot of time playing completely disgusting computer games that have no redeeming social value.
In spacetime, all events are baked together: a four-dimensional continuum. Past and future are no more privileged than left and right or up and down.
Strangely enough, the linking of computers has taken place democratically, even anarchically. Its rules and habits are emerging in the open light, rather shall behind the closed doors of security agencies or corporate operations centers.
Humorists are using Twitter to tell jokes in an interesting way. It doesn't have to be profound, and it doesn't have to be earth-shaking, but it is transformative.
Particle physicists may freeze a second, open it up, and explore its dappled contents like surgeons pawing through an abdomen, but in real life, when events occur within thousandths of a second, our minds cannot distinguish past from future.
A bit, the smallest unit of information, the fundamental particle of information theory, is a choice, yes or no, on or off. It's a choice that you can embody in electrical circuits, and it is thanks to that that we have all this ubiquitous computing.
Is privacy about government security agents decrypting your e-mail and then kicking down the front door with their jackboots? Or is it about telemarketers interrupting your supper with cold calls? It depends. Mainly, of course, it depends on whether you live in a totalitarian or a free society.
We say that time passes, time goes by, and time flows. Those are metaphors. We also think of time as a medium in which we exist.
The cells of an organism are nodes in a richly interwoven communications network, transmitting and receiving, coding and decoding. Evolution itself embodies an ongoing exchange of information between organism and environment.
Genes themselves are made of bits.
People worry about Twitter. Twitter is banal. It's 140-character messages. By definition, you can hardly say anything profound. On the other hand, we communicate. And, sometimes, we communicate about things that are important.
Every time a new technology comes along, we feel we're about to break through to a place where we will not be able to recover. The advent of broadcast radio confused people. It delighted people, of course, but it also changed the world.
A book is not necessarily made of paper. A book is not necessarily made to be read on a Kindle. A book is a collection of text, organized in one of a variety of ways. You could say that words printed on paper and bound between cloth covers will someday be obsolete. But if and when that day comes, there will still be a thing called books.
Flying was great. You have to think fast. You have to develop intuition about the physics of air moving quickly over a surface.
The ability to write and read books is one of the things that transformed us as a species.
Wikipedians believe (and I do, too) that bits, being abstract, will outlast paper.
Because everyone in the world has the power to edit, Wikipedia has long been plagued by the so-called edit war. This is like a house where the husband wants it warm and the wife wants it cool and they sneak back and forth adjusting the thermostat at cross purposes.
Memes can be visual. Our image of George Washington is a meme. We don't actually have any idea what George Washington looked like. There are so many different portraits of him, and they're all different. But we have an image in our head, and that image is propagated from one place to another, from one person to another.
I take the view that we all have permission to be a little baffled by quantum information science and algorithmic information theory.
A good part of 'The Information' is about the transition from an oral to a literary culture. Books effected such a great transformation in the way we think about the world, our history, our logic, mathematics, you name it. I think we would be greatly diminished as a people and as a culture if the book became obsolete.
You know, entropy is associated thermodynamically, in systems involving heat, with disorder. And in an analogous way, information is associated with disorder, which seems paradoxical. But when you think about it, a bit of information is a surprise. If you already knew what the message contained, there would be no new information in it.
As for memes, the word 'meme' is a cliche, which is to say it's already a meme. We all hear it all the time, and maybe we even have started to use it in ordinary speech. The man who invented it was Richard Dawkins, who was, not coincidentally, an evolutionary biologist. And he invented it as an analog for the gene.
One measure of twentieth-century time is the supersonic three and three-quarter hours it takes the Concorde to fly from New York to Paris, gate to gate. Other measures come with the waits on the expressways and the runways.
Alphabetical order had to be invented to help people organize the first dictionaries. On the other hand, we may have reached a point where alphabetical order has gone obsolete. Wikipedia is ostensibly in alphabetical order, but, when you think about it, it's not in any order at all. You use a search engine to get into it.
