Information is not knowledge, and knowledge is not wisdom. Reading - even browsing - an old book can yield sustenance denied by a database search. Patience is a virtue, gluttony a sin.

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.

We choose mania over boredom every time.

Information is crucial to our biological substance - our genetic code is information. But before 1950, it was not obvious that inheritance had anything to do with code. And it was only after the invention of the telegraph that we understood that our nerves carry messages, just like wires.

We have met the Devil of Information Overload and his impish underlings, the computer virus, the busy signal, the dead link, and the PowerPoint presentation.

Every new medium transforms the nature of human thought. In the long run, history is the story of information becoming aware of itself.

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.

To continue down the path of comprehensiveness, Wikipedia will need to sustain the astonishing mass fervor of its birth years. Will that be possible? No one knows.

For a brief time in the 1850s, the telegraph companies of England and the United States thought that they could (and should) preserve every message that passed through their wires. Millions of telegrams - in fireproof safes. Imagine the possibilities for history!

Children and scientists share an outlook on life. 'If I do this, what will happen?' is both the motto of the child at play and the defining refrain of the physical scientist.

The word 'code' turns out to be a really important word for my book, 'The Information.' The genetic code is just one example. We talk now about coders, coding. Computer guys are coders. The stuff they write is code.

Information theory began as a bridge from mathematics to electrical engineering and from there to computing.

It is seldom right to say that anything is true 'according to Google.' Google is the oracle of redirection. Go there for 'hamadryad,' and it points you to Wikipedia. Or the Free Online Dictionary. Or the Official Hamadryad Web Site (it's a rock band, too, wouldn't you know).

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.

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.

I'm trying to look at many, many things in modern life that I believe are going faster, and I'm trying to look at why they're going faster and what effect they have on us. We all know about FedEx and instant pudding, but it doesn't mean we've looked at all the consequences of our desire for speed.

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.

It is significant that one says book lover and music lover and art lover but not record lover or CD lover or, conversely, text lover.

When people say that the Internet is going to make us all geniuses, that was said about the telegraph. On the other hand, when they say the Internet is going to make us stupid, that also was said about the telegraph.

As a technology, the book is like a hammer. That is to say, it is perfect: a tool ideally suited to its task. Hammers can be tweaked and varied but will never go obsolete. Even when builders pound nails by the thousand with pneumatic nail guns, every household needs a hammer.

Scientifically, information is a choice - a yes-or-no choice. In a broader sense, information is everything that informs our world - writing, painting, music, money.

In general, I think people should be skeptical of the Internet as a reference tool because so much of what's on it is unreliable and costumed - a hall of mirrors.

As soon as the printing press started flooding Europe with books, people were complaining that there were too many books and that it was going to change philosophy and the course of human thought in ways that wouldn't necessarily be good.

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.

For the modern physicist, reality is the whole thing, past and future joined in a single history. The sensation of now is just that, a sensation, and different for everyone. Instead of one master clock, we have clocks in multitudes.

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.

With the advent of computing, human invention crossed a threshold into a world different from everything that came before. The computer is the universal machine almost by definition, machine-of-all-trades, capable of accomplishing or simulating just about any task that can be logically defined.

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.

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.

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.

Cyberspace as a mode of being will never go away. We live in cyberspace.

Type 'What is th' and faster than you can find the 'e' Google is sending choices back at you: 'What is the cloud?' 'What is the mean?' 'What is the American dream?' 'What is the illuminati?' Google is trying to read your mind. Only it's not your mind. It's the World Brain.

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 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.

Encyclopedias are finished. All encyclopedias combined, including the redoubtable Britannica, have already been surpassed by the exercise in groupthink known as Wikipedia.

For much of the twentieth century, 1984 was a year that belonged to the future - a strange, gray future at that. Then it slid painlessly into the past, like any other year. Big Brother arrived and settled in, though not at all in the way George Orwell had imagined.

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.

Patents have long served as a fundamental cog in the American machine, cherished in our national soul.

At its most fundamental, information is a binary choice. In other words, a single bit of information is one yes-or-no choice.

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.

Genes themselves are made of bits.

I take the view that we all have permission to be a little baffled by quantum information science and algorithmic information theory.

Google is where we go for answers. People used to go elsewhere or, more likely, stagger along not knowing.

We get better search results and we see more appropriate advertising when we let Google know who we are.

Flying was great. You have to think fast. You have to develop intuition about the physics of air moving quickly over a surface.

If instantaneity is what we want, television cannot compete with cyberspace.

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.

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.

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.

It's fair to say that Wikipedia has spent far more time considering the philosophical ramifications of categorization than Aristotle and Kant ever did.
