Question: Is there an equation to calculate: how high the water will splash if you drop an object onto water?
I know it depend on water density, area in contact, object density, force causes....etc.... but don't know the exact equation

This is probably a stupid question but why do people catch a cold when they got drenched in the rain. A cold is a viral condition while getting drenched is a physical condition. Does the immunity system drop when people are exposed to low temperatures?

I think I've heard somewhere that the body temperature weakening your immune system thing is a myth with no empirical evidence. It's pretty much made up by people who understand diseases but try to rationalize the folklore reasons for colds.
I haven't actually studied it, but assuming that people actually do statistically get more colds after being drenched or leaving the window open (you can't just assume that, although so many separate cultures associate colds with well, coldness, that it seems reasonable that it might be true), I would guess that it has to do with increased exposure. Your hands get wet and you touch doorknobs and such that have also been touched by people who got their hands wet. Presumably it's easier for virii to move in liquids (although maybe not). Leaving the window open causes air to circulate more, including air with virii. These are just guesses though. |

Wearing your energy levels down through extremes and stress can increase your odds of getting sick because your immune system is compromised. That's about the ONLY connection to most of the folklore stuff.
Colds are viral critters... there are many varieties and they mutate fast. Most immune systems don't adapt fast enough to ward them all off. Second... many people mistake allergic reactions for cold symptoms. Mold and pollen can deliver symptoms that are easy to mistake for a cold. Wash your hands with soap and dry them. Amazingly simple avoidance technique and amazingly ill-practiced.

High-Vision is the equivalent of "High-Definiton Television" (aka HDTV):

Is there a link to said trailer?
I remember a similar thing coming out for April Fool's a while back. It was a fake trailer for a live-action Zelda movie created by IGN. It was very well done and they even released a 'making of' video later to show how they put the trailer together. For the amount of work they put into it it was very easy to think it was for an actual movie. |

Something I've been wondering about Korean manhwa recently. Many of the male characters are difficult to distinguish from females, while in Japanese manga it is usually very easy to tell the difference between the genders. Is there any specific reason why the genders look so similar in Korean stories?

Simple answer: it's because its drawn more realistically.
