What was WolframAlpha? And who was this Stephen Wolfram? These two questions popped up on my head when I first heard about it in This Week in Tech #195. So we asked Piyatad (Job) and Worawat to do some research for the episode so we could talk about it. This is in reference to the site, http://www.WolframAlpha.com, the computational knowledge engine (as written on the site). The service was good, full of results and we were all impressed and hope to spread some news for this site.
