I have never understood why scientists tend to name their discoveries with long, impossible-to-spell names. If I discovered a whopper of a red giant, I would name it Bob, not Betelgeuse. A dinosaur could be Ed instead of a diplodutlosauraus, and a tiny wild flower could be Meg instead of Megaminiolopous.

Sometimes we shorten those gigantic names anyway. Do you know the full name of Mt. Popo? I don't. The correct name for Rex is really Tyranosaurus Rex, but I'll bet even his mother didn't call him that.*

It's no wonder we use acronyms. Why didn't they just name TNT and DDT something like Tnt or Ddt? Well, I guess they need some vowels so we could say, "Blow it up with Tint." or "Spray those critters with Didit." Then when some pest asks you if you know what TNT and DDT stand for, you wouldn't have to look it up.
