“ Computational knowledge engine that draws on multiple sources to answer user queries directly. „
You don't get to see the future much. But wolframalpha is. Wolframalpha (WA for short in this review) is a cutting edge "Computational knowledge engine", basically, a search engine.
But you can't ask this to find you "Free flash games" or "Free money online". It offers a different kind of knowledge. Say you wanted to convert feet to inches, you might go on ask.com, type in feet to inches, and you might click on another website to get your answer. Type it in WA and it will give you the proper chart. Put in your birthdate, and it will tell you the day you were born, when the sun rose and set, how many years weeks or days ago it was, any events that happened on your birthday, who else was born on your birthdate (Che Guevara was born on the 14th june to). Try to find all that out on google or ask.com in the same time I found it on wolfram. And it can do alot more. It can tell you the tide times for your area, it can do any advanced math sum, and tell you the mass of pluto. It can compare stocks, and all without clicking on another webpage
You to can add things to WA. They are always looking for members of the community to help out with wolframalpha, from helping wolfram evolve into new languages, to just helping on a certain topic you are good at. And 10 or 20 years down the line, this could be amazing. You could be walking down the street, and wanting to know the tide times for whatever reason. You pull out your phone, and just say into it "Tide times for my location", and it could tell you. It could be used for just about anything.
I suggest you take a good look at wolframalpha. You willl honestly love it. If you ever need to look up something like the tide times, just ask WA instead, and see how much easyer it is. I am using wolfram all the time now, and I am finding it much easyer than scrolling through 1.3 million results on google filled with advertisements, and not finding what I want. It really is nice to just have your infomation there ready to read. THere is a toolbar for wolframalpha you can download for firefox and IE. So go and give it a try.
