The future ain’t what it used to be

As anyone who’s played the ponies, visited Tomorrowland or flipped through an old issue of Popular Mechanics can tell you, predicting the future is no mean feat. Even when we get the broad strokes right, we often misgauge society’s responses. Scientists reveal, inventors dream, engineers build and marketers flog, but human nature has the final say.

Prediction is a sucker’s game, but we have to play: If we don’t predict, we can’t plan. In this article, I look at how the field of futurology developed – and how it works.

The ins and outs of the antipodean swirlie

Maelstrom

If you’re an Aussie dag and some bogan is giving you a dunnyflushing, why not spend the time constructively? Watch which way the water swirls down the bog, and then call one of your nerdier Yank mates and compare notes on swirlie physics. Will this settle the age-old argument? Hardly. But, hey, it’s something to pass the time.

“You know, you can see it for miles – goes on for miles, over the hills and everything. But, so does the M6. Do you know what I mean? You can see that for miles. And you go, ‘Great. And that does a job. You can drive on that.’” Thus did an unimpressed Karl Pilkington of An Idiot Abroad describe the Great Wall of China, allegedly the only manmade object visible from space.

Which raises and interesting question: Why can’t you see the British M6 motorway from space? Or can you? For that matter, can you actually see the Great Wall?

Sometime around Halloween 2011, the global population topped seven billion. That’s a staggering number of people. In fact, linked arm to arm, a human chain would wrap around the equator roughly 175 times or extend to the moon and back about nine times, according to CBC/Radio-Canada.

Bearing this image in mind, we can be forgiven for believing that there are more humans roaming the Earth today than during all of history and prehistory combined. But is it true?

Are There More People Alive Today than Ever Lived?
