Why don't reptiles produce their own heat, physically how do they NOT and is this preferential to being warm blooded? | There are several advantages, as well as disadvantages, to being cold blooded.

Conditional probability (searched already. Other explanations posted are way too complex) | What's the probability of flipping two coins and they both turn up heads? That's pretty easy to calculate, it's 25%. But what if you flipped one already, and it was heads? Now the probability of both being heads is 50%, it's just down to the second coin flip.

Why does hitting a dim fluorescent lightbulb help make it bright? | I'm not sure of this mechanism. My guess is that the contact between the bulb terminals and the fixture is not very good.

Flicking the bulb could break through this oxidation and get you a... |
Why are certain American movies released in some other countries before they're released in the USA? | There's a whole ton of math that goes into when a movie gets released, based on competition, based on local culture, based on how the reviews might go, based on various deals with the theaters, based on well, you get the idea.

Why wouldn't Americans want improved relations with Russia? Why have they been demonized by our media and politicians? | America would love improved relations with Russia.

What are ocean currents? How do they work? | I am not an oceanologist, but I'll do by best. The main factors as far as I know are temperature and salinity. Water in the northern areas cools and becomes more dense, causing it to sink. This sinking action causes warm water from the equator to displace it. The cold water is slowly pushed back to the ewuator, where i... |
