I Understand Most Of This


If you had a stationary camera which was pointed it at the western sky and you took a picture every twelve days at 5:30 p.m., this is what the sun would look like in each of the photos. (This frequency and time is actually my best guess from looking at the photo, but I know the photo was taken at the exact time of day on several days throughout one year.) I knew the sun would be higher in the sky in summer and lower in the sky in winter but that figure eight kinda surprises me. (Source as found here.)

The earth's angle on its axis along with the fact that it is rotating around the sun at a different angle than the tilt accounts for the figure eight. At each pole, no figure eight exists. At the equator, the figure eight has equal halves.
I miss Carl Sagan.

You interpreted it correctly. The figure 8 is because the earth is slightly tilted with respect to what we would think of as north and south. If the earth's north south axis were exactly perpendicular to the sun, the figure 8 would go away.

Wow...2 correct answers to an astronomy/physics question.

We must have some outsiders reading this blog.

If you had a stationary camera... and no friends to speak of to give you something else to do...

I was pretty much going to say what 13:39 said but go into detail. I've studied science ever since I was 10 years old.

C4U, who needs friends anyway? I hate friends...

Perhaps you would be interested in the Foucault Pendulum? It is fascinating in Chicago!
