Difference or two of the same?

Question

FOG and MIST?
Are they the same thing or not? If not, whats the difference?

Answer 1

Fog is made of smaller particals. What you would get if the tempture in a river was warmer then the Air tempther. Fog would "Rise" as the tempture of the water would try to equlize with the temp of the air.
Mist is much larger and "Falls" from the sky.

Answer 2

Mist is larger sized particles than fog, so they fall out of the sky easier to wet the pavement and you can also feel them more on your skin. Here is the official definition from the Glossary of Meteorology:

mist—1. A suspension in the air consisting of an aggregate of microscopic water droplets or wet hygroscopic particles (of diameter not less than 0.5 mm or 0.02 in.), reducing the visibility at the earth's surface to not less than 1 km or 5/8 mi.
The term mist is used in weather reports when there is such obscurity and the associated visibility is 1000 m or more, and the corresponding relative humidity is 95% or more, but is generally lower than 100%. These hydrometeors form a thin greyish veil that covers the landscape. It also reduces visibility, but to a lesser extent than fog. 2. In popular usage in the United States, same as drizzle.

The definition of fog is too long to include here, but you can see it at http://amsglossary.allenpress.com/glossary/search?id=fog1

Answer 3

I have not heard of MIST, but FOG is typically what math people use as a short hand for composition of functions. FOG stand for the f(g(x)). This basically means you put one function let's say 2x, into another function sin x, to get a new function, sin 2x. This basic concept is essential to one of the basic rules in calculus.

I'm not sure what MIST is exactly though.
