Need an Answer? WolframAlpha to the Rescue

Wednesday, May 20th, 2009

WolframAlphaI love Stephen Wolfram. First he came up with the tool Mathematica, then a new way of modeling complex systems with A New Kind of Science. Now he’s created a tool that purports to “make all systematic knowledge immediately computable by anyone.”

What does that mean? It means you ask WolframAlpha a question and it gives you an answer. I asked “What’s the population of Vermont” and got a nice little stack of information. Or you can put in just one word such as “timbuktu.” Or you can put in two words, such as “Vermont North Dakota” or “IBM Apple,” and see the two sets of data compared side by side. (FYI, VT and ND have almost exactly the same population; IBM has fared better than Apple in stock price over the past year.)

Where does WolframAlpha get its info? According to The Guardian, from “the dark corners of libraries, government files and science labs around the world – with a little bit of human quirk thrown in for good measure.” The quirk is there to build credibility with early-adopters, such as geeks who already found these WolframAlpha easter eggs.

But it couldn’t handle a query such as “Can robots think?” or even “robot intelligence.” Oh well.  It’s still getting bookmarked.

Our robot-ruled future (it’s not as scary as you think)

Most people have an idea of what a robot should do: it should serve us –- cart snacks over to the couch, rub our feet, make the bed. Kind of like a slave, which is when all the worries about robot consciousness crop up. Uh oh!

But the technology coming out of robotics allows your camera to self-focus and gets rid of pink-eye. It’s also allowing for better medical treatment with regard to, for example, prostate surgery (just went to a lecture on this last night, with video).

In fact, maybe someday –- and this is the most fascinating robot-related research I’ve read about recently — you’ll be able to pull a mobile phone out of your pocket and morph it into a laptop. Seriously. I’m shivering over here.

Periodic Table of Videos makes elements fun – especially K

Periodic Table of Videos

My 11th-grade chemistry teacher was five feet tall with four-foot boobs and wore lab coats over her minidresses (no, this wasn’t the ’60s) so all you saw were her spindly toothpick legs on top of platform shoes.  Sounds cool, doesn’t she?

But she wasn’t cool at all.  In fact, she was so crabby and had such an instant dislike to me that I despised chemistry class, including all the experiments that I otherwise would have loved.  (At least my Physics teacher was kind of nice.)  But now I can re-learn fun facts about all the elements with The Periodic Table of Videos.

It’s such a blast!  Just click on an element and discover some of its most interesting qualities.  Right now K (potassium) is my favorite.  It’s highly reactive and according to Professor Martyn Poliakoff (the vid host), one of his colleagues describes it as evil — wha-ha-ha.  Check it out:

“Revenge of the Nerdette” – Nerdette?

Sunday, June 22nd, 2008

Nerd Girls and their solar car

A recent story in Newsweek, “Revenge of the Nerdette,” focused on a team of “knock-out braniacs” – the Nerd Girls – a group of women engineering students at Tufts U.

This is a good thing, right? Women engineers should be in the news. Engineering itself should be in the news so that kids (especially girls) can learn how interesting it is. And what the “Nerd Girls” are doing is interesting: they’re building a solar car.

So then why was this story in the “Culture” section of the mag instead of “Technology”? And did the title really have to add the diminutive “ette” to nerd?

Apparently, it’s still news – cultural news – that women can be smart and pretty AND/OR can be interested as well as talented in the sciences.

Let’s at least make it tech news next time, okay?
