From three years ago, twenty years after Idle wrote the song:
http://ephemeris.sjaa.net/0312/b.htmlIt's from the San Jose Astronomical Association, written three years ago, twenty years after Idle wrote his song.
Here's a piece from it:
Just remember that you're standing on a planet that's evolving
While still controversial in some areas, evolution seems pretty well established.
And revolving at nine hundred miles an hour,
The speed of the earth's revolution is once per day (duh) but at the equator the circumference of the earth is 25,000 miles so that makes the speed just over 1,000 miles per hour. However, by the time you get as far north as the UK (Eric Idle's country) the speed is actually less than 700 miles per hour. The 900 figure might be good enough for our purposes.
That's orbiting at nineteen miles a second, so it's reckoned,
The earth orbits the sun at 29km/second and there is roughly a 3:2 ratio between kilometers and miles so 19 miles per second is pretty close.
A sun that is the source of all our power.
This may be a bit of hyperbole. The sun is responsible for all wind and solar power and because our weather depends on the sun we would include hydroelectric power as well. Oil and coal formed as a result of sun-driven processes on earth so that's okay. But this particular sun did not create uranium so it could be argued that it doesn't supply all of our power. IMHO.
The author goes through the whole song this way.
