Question for students doing science or sumthin (thicko question)Watch
Aphelion and apogee
Perihelion and perigee
They refer to closest points and furthest points in a planet's or satellite's orbit. My question is what is the actual difference? Why is it the Earth has a perihelion and the Moon has a perigee? For all intents and purposes they are the same thing but with different words. Why do scientists do this?
The military are even worse. They love their acronyms very much. "Head for G2 and I'l meet you there at 14:00". In other words he will be at the pub at 2 o clock. Sometimes their acronyms take longer to say than their definitions. Why say I.E.D when u can simply say "bomb"? Which brings me onto yet another silly question.
The word for my arse is spelled "bum" and not "bumb". So why is bom spelled "bomb"?
