The Fifties and Sixties were years of unreal optimism about weather forecasting. Newspapers and magazines were filled with hope for weather science, not just for prediction but for modification and control. Two technologies were maturing together: the digital computer and the space satellite.
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.
Encyclopedias are finished. All encyclopedias combined, including the redoubtable Britannica, have already been surpassed by the exercise in groupthink known as Wikipedia.
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.
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.
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.
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.
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.
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.
