Wolfram|Alpha’s long-term goal is to make all systematic knowledge immediately computable and accessible to everyone.
We 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. Our goal is to build on the achievements of science and other systematizations of knowledge to provide a single source that can be relied on by everyone for definitive answers to factual queries. Wolfram|Alpha is an engine for computing answers and providing knowledge. It works by using its vast store of expert-level knowledge and algorithms to automatically answer questions, do analysis, and generate reports.
( Unbelievable what this thing can compute; you can ask it near anything and find an answer.I tried it a few times.)
