In a pinch when you need quick information most people turn to a popular search engine for knowledge, like Google or Yahoo. These sites are great for researching websites that contain information that might lead you to the solution you were looking for, but what if you just wanted the answer without all the searching through webpages?
Well this morning I came across a website that prides itself on being a computational knowledge engine. I, or course, put it through a series of random inquiries and was quite impressed with the outcome. If you need information to a question or calculation, instead of pointing you to a website it just answers it.
I was surprised to see that it pulls information from a wide array of places. It was even able to solve the algebra equations that I threw at it with numbers and graphed lines. I am sure that most of you won't need it to solve your geometry homework, but it will perform all sorts of calculations and conversions.
So, next time you are in need of an answer and don't have time to search around a bunch of websites, go to http://www.wolframalpha.com/ and find the information you need.
