A tin foil star

E-word,

Really quickly. I know the difference between deg(rees) and rad(ians). It a way of measuring an angle. 360 degrees, as you know, is when an angle goes all the way around and is back at its original angle. Equally, 2*Pi radians means the same thing. Converting from degrees to radians is as simple as taking your angle, multiplying it by pi, and dividing that total by 180.

Also, I bet you didn't know the different between a meteorite and a meteoroid. I didn't know myself until several minutes ago.

Meteorite \Me"te*or*ite\, n. [Cf. F. m['e]t['e]orite.] (Min.) A mass of stone or iron which has fallen to the earth from space; an aerolite. [1913 Webster]

Meteoroid \Me"te*or*oid\ (m[=e]"t[-e]*[~e]r*oid), n. [Meteor + -oid.] (Astron.) A small body moving through space, or revolving about the sun, which on entering the earth's atmosphere would be deflagrated and appear as a meteor. [1913 Webster]

Subtle, eh? A meteorite is a fallen meteoroid, which before becoming a meteorite, is a meteor.
