Kicking off our conversation, Stephen remarks that, "Wolfram|Alpha isn't really a search engine, because we compute the answers, and we discover new truths. If anything, you might call it a platonic search engine, unearthing eternal truths that may never have been written down before..."
Wolfram|Alpha can pop out an answer to pretty much any kind of factual question that you might pose to a scientist, economist, banker, or other kind of expert. The exciting part is that you're not just looking up pages on the web, you're getting new information that's generated by computations working from the known data. Wolfram says the response can be so speedy because, "We've found that, of all the things science can compute, most take a second or less."
Wolfram sees his new program as being part of a history of mankind's attempts to systematize knowledge. "We have the encyclopedists trying to write everything down. We have people like John Wilkins trying to create an analytical language for thought. We have philosophers and scientists hoping to find a universal theory of the world. But all these attempts founder on the vastness and the subdivisibility of the tasks."
He feels that the turning point came with Newton and Leibniz. "Before Newton, nobody had the notion of trying to compute the truth. They always thought in terms of reasoning things out like a human would do. But the point isn't to emulate a human being. The point is to find an answer. Leibniz came closest to the notion of Wolfram|Alpha, with his plan for a universal library, and with his dream of a logical system for calculating truth."
Alex Wood is an addict but won’t give up his smartphone. But he has five strategies for limiting its control over him: “I used to wake up tired. My body would ache and my head felt sore, like waking up with a hangover. Finally, I took control, like attending an AA class for addicts, I […]
Ok, it’s not just solar powered. It’s also an anti-theft, waterproof marvel that keeps my phone’s power bar from ever getting into the red.Sure the idea seems obvious now – tuck a gigantic solar powered battery pack into an exposed slot and turn the wearer into a walking energy harvester. Simple maybe, but I didn’t […]
You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
Custom coffee vessels are the perfect piece of office flair, but it’s just a matter of time before your VOTE FOR PEDRO mug will start to lose its relevant wit. Why not have a new one every day, with whatever silly nonsense you want sticking off the sides? You can save big on your novelty […]
