Wolfram|Alpha is the new computational knowledge engine from the makers of Mathematica. Setting itself the lofty-goal to “make all systematic knowledge immediately computable and accessible to everyone. With the aim to collect and curate all objective data; implement every known model, method, and algorithm; and make it possible to compute whatever can be computed about anything.”
While Google searches for websites that show the information you need, Wolfram|Alpha actually understands the information on these pages, and collates it for you, displaying all the data that it considers relevant.
For example, do you want to know how many US dollars, you can buy for $10 Australian dollars? Wolfram|Alpha will tell you straight up. Plus it will tell you the past 12 months exchange history, current exchange rates against other major currencies, and more.
Want to know the local temperature when David Beckham was born? Wolfram|Alpha finds out the birthdate, birthplace, and then looks up weather charts based on this information. Wind speeds, level of cloud cover, humidity, sunlight intensity is all displayed.
Or perhaps you want to know if the burgers really are better at Hungry Jacks? Wolfram|Alpha can tell you that too. Dietary information such as calories, fat content, sodium levels etc are all at your mercy.
For the studious types, Wolfram|Alpha also links to the source of its information, so you can ensure it’s validity, and also to make referencing easier.
So check out Wolfram|Alpha, and let us know what you think.
