Wolfram Alpha and Google wave!!!

Today, the internet and things like Wolfram|Alpha and Google Wave made our life more easy.

Stephen Wolfram created the Wolfram|Alpha with the goal to make all systematic knowledge immediately computable and accessible to everyone. In Wolfram|Alpha you can enter your question or calculation and Wolfram|Alpha uses its built-in algorithms and a growing collection of data to compute the answer which is made possible by the achievements of Mathematica and A New Kind of Science (NKS) or WolframScience and webMathematica. As of now, Wolfram|Alpha contains 10+ trillion pieces of data, 50,000+ types of algorithms and models, and linguistic capabilities for 1000+ domains. You can take tutorials about how to use WolframAlpha and also go through the WolframAlpha blog .

At the same time Google Wave provides almost real time chat with friends and colleagues and also provides a tool for collaboration where you can discuss about group projects, have brainstorming session and can work together using text, photos, videos, maps etc...and can also play interactive games... You can reply anywhere in the message, edit the content and add others at any point in the process. Playback feature provides more flexibility to rewind through messages.
