Collected Answers from the Wikipedia Reference Desk

I help out by answering questions at the Wikipedia reference desk. Mostly, the questions and answers are quite forgettable - but once in a while a question demands an in-depth answer - and a few of those are worth holding onto.

Here are some of my favorites (in most cases, I've tidied them up since the original posting.)

• Extra Dimensions in String Theory explained.
• Chaotic systems are random.
• Macroscale laws from Nanoscale randomness.
• When will the oil run out?
• Graphics cards and Games.
• Graphics refresh rates and VSYNC.
• Cars crashing head-on or into a wall.
• Statistical scam.
• Who is Sam Taliaferro?
• You know you are a crank when...
• Confusion between Force and Energy
