Wolfram Alpha is a "computational knowledge engine", which in Layman's Terms means it's a computer you ask things and it tells you.
Yes, it knows the answer.
No, it is (probably) not run by demonic lawyers.
Wolfram Alpha provides examples of the following tropes:
- A God Am I: As evidenced here.
- Easter Egg/The Dev Team Thinks of Everything: If it is a well-known question from pop culture, it's probably programmed into Wolfram Alpha.
- The aforementioned Hitch Hikers Guide to The Galaxy answer.
- What does Marcellus Wallace look like?
- African or European swallow?
- Hiroshima as a Unit of Measure: Wolfram Alpha's designed to give units such as these for any answer involving measurements. It doesn't always seem to get the part where such units are supposed to be "well known", though, instead doing things like comparing lengths of time to equinox procession periods.
- Logic Bomb: Put in "x iff !x" (x is true if and only if x is false) and it throws out stock numbers for IFF, because that is better than the alternative.
