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.

I'll cheerfully confess to spending a lot of time playing completely disgusting computer games that have no redeeming social value.
-
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.
-
It's important with any new technology to try to pay conscious attention to what the drawbacks might be. We choose to multitask. Sometimes our choices aren't the wisest of choices, and we regret them, but they are our choices. I think it'd be wrong to think that they're automatically bad.

Basic dictionaries no longer belong on paper; the greatest, the 'Oxford English Dictionary,' has nimbly remade itself in cyberspace, where it has doubled in size and grown more timely and usable than ever.
-
Google is where we go for answers. People used to go elsewhere or, more likely, stagger along not knowing.
-
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.

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 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.

In the thousands of articles that made up the technical literature of chaos, few were cited more often than 'Deterministic Nonperiodic Flow.' For years, no single object would inspire more illustrations, even motion pictures, than the mysterious curve depicted at the end, the double spiral that became known as the Lorenz attractor.

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.

As the Earth continues to slow, leap seconds will grow more common. Eventually we will need one every year, and then even more. Scientists could have avoided these awkward skips by choosing instead to adjust the duration of the second itself. Who would notice? That is what they did, in fact, until 1955.

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.

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.

Computer programs are the most intricate, delicately balanced and finely interwoven of all the products of human industry to date. They are machines with far more moving parts than any engine: the parts don't wear out, but they interact and rub up against one another in ways the programmers themselves cannot predict.

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.

Information theory began as a bridge from mathematics to electrical engineering and from there to computing.
-
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.
-
Encyclopedias are finished. All encyclopedias combined, including the redoubtable Britannica, have already been surpassed by the exercise in groupthink known as Wikipedia.
-
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.
-
In cyberspace, the Wikipedians never stop gathering: It's a continuous round-the-clock rolling workfest.
-
Patent battles have become a strong catalyst for mergers, reducing competition in various domains. The largest corporations, with gigantic patent portfolios, routinely enter into cross-licensing agreements with their largest competitors.
-
Wikipedians believe (and I do, too) that bits, being abstract, will outlast paper.

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.
