Wolfram|Alpha

Wolfram|Alpha is a new search engine from the people at Mathmatica - actually called Wolfram Research. Steven Wolfram is the writer of Mathmatica, and the visionary who thinks that the computationally centered Alpha search engine will do things people don't know that they need done. 

It does things that Google does not do well. I know that Google does calculations, but put in 100 Pascal-seconds into Wolfram|Alpha and it converts it into all the different units one would want. I can never remember the Google syntax for that. 

If you put chemical names into it, then it gives the structure, the toxicity properties, the physical characticistics, even the NFPA diamond. 

This is a pretty good search engine, and I can't wait to tell people about it.
