Gray Matter's own Theodore Gray reports from his day job at Wolfram on how his new "knowledge engine" provides exactly what Google can't

OK, it may not be much fun, but I think it's safe to say that for most people, it's more fun than doing that integral yourself by hand. Wolfram|Alpha: It's more fun than having your teeth pulled!

But seriously, in case you're a teacher and wondering if this is the apocalypse: well, in some ways yes, but keep in mind that whether you knew it or not, students who have had access to Mathematica have been able to do this kind of stuff for the past twenty years. Progress happens, and Wolfram|Alpha is essentially just leveling the playing field, giving everyone free access to the kind of power that only a few have had before.

Another example: A couple of weeks before the site launched I got an email from another editor at PopSci asking if I could help with a question that had come up during research for a story. The question was, if you used 121 exajoules of energy over the course of a year, how many gigawatts of continuous power would that represent?

This is exactly the kind of actual problem that Wolfram|Alpha does very well at. Not only does it give you the answer, it tells you some useful comparisons, for example that this quantity is 1.2 times the U.S. annual power consumption. Since, unbeknownst to me, the story they were working on involved the projected future power consumption of the U.S., this was very good confirmation that the number is right, and not off by a factor of a thousand or something.

Over the last week we've seen the reporting on Wolfram|Alpha deepen and broaden, and I'm very happy to see that, by and large, people get it. They're understanding that this is something completely new, it's not what anyone expected, and although it's rough around the edges and far from complete, it's obviously an interesting project. (Of course, there are always the standard "you're all idiots" comments from the people who have never actually done a complex project themselves, but really, even on some of the nastier sites, I've been surprised at the number of positive comments. It's way above average from what I can tell. Maybe because we do their homework for them.)

And for us this is a marathon, not a sprint. One reason we brought Wolfram|Alpha live at this point is that we thought we'd gone about as far as we could without contact with the public. For example, the degree to which Wolfram|Alpha can understand natural language queries will improve hugely as we start to analyze and pick apart the syntax of the countless millions of real live queries we have gotten from the public just in the last week, paying special attention to the ones that failed. The language parsing will improve, and we will add new data sets to cover areas we are currently missing. (Yes, sports scores are on the list!)

Wolfram|Alpha is here to stay, and it will keep getting better. In the meantime, I should be able to return to do another column next month. I'm thinking about taking an X-ray picture of my hand using a roll of Scotch tape.

Shouldn't the phrase "recuse yourself" play some role in this?

I really like the engine, it has been pretty useful for homework already, but it does have its problems even in areas its tries to excel. Well my only complaint really is the lack of international knowledge but hopefully that will improve. I was trying to do some homework comparing some companies, and I could find American traded corporations easily but could not find any information about companies traded in other markets. The company comparison on the site is quite useful but some of the largest companies in the world are missing.
Anyway, I didn't know about that nutrition information thing thats cool.
