Thread: Cool Site - Computational Knowledge Engine

Here is a site I found by accident and had to share as I found it to be outstanding. Ever needed help with a math problem you couldn't figure out this would have been a great tool to use. Does more then math!!! Like ever wanted to know how many day you been alive input your birthday

Today's Wolfram|Alpha is the first step in an ambitious, long-term project to make all systematic knowledge immediately computable by anyone. Enter your question or calculation and Wolfram|Alpha uses its built-in algorithms and a growing collection of data to compute the answer. Based on a new kind of knowledge-based computing...

Will save your queries in a pdf format also. I did

0.002 + e^(i pi) + sum 1/2^n (n = 1 to infinity)

And it gave the right result to the problem.

Can check it out here Wolfram|Alpha

I used Wolfram|Alpha on an almost regular basis. It's really a brilliant site!

Been entertaining myself for sometime this evening with this. Love how simple things 7/8= or even .09= are done and samples given. Found this search interesting "MSFT YHOO GOOG"

Think whats cool is you get the result you want right up front with out going through countless sites. Like a simple term of United States gives a good amount of information. Gives some info even if you type in a domain name.

How long has this site been around anyone know?

Only about 10 months.

Absolutely! Was actually amazed when I first used it. Even introduced it to my students knowing that they too may appreciate the site.

Wolframalpha is great, very good for quadratic equations...
