Passing the Equinox

I make a point to appreciate these grey days, numbered by the approach of Spring, in which seagulls disappear briefly when they bank, only to emerge as black ribbons when the wind changes direction. Obligations are lower when the day's sun is shrouded in white cloth, and I am happy to presently cower within its comfort; happy to hide from the wave of extroversion I can see on the horizon (gleaming with squeezed smiles and unnecessary skin).

Blogger hipp-o thought:

Speaking of the equinox - have you noticed over the past two weeks how each day it seems like its getting noticeably lighter out later each day?

and then i realized, of course! we're on the steep part of the sine curve!

So we are at Point A now, the spring equinox (also E).
Notice how the curve is steep? So the first derivative will be a large + number. So we are moving speedily towards the top, point B, which is summer and long, lazy nights and condensation on cold beer cans.

Notice how around point B (summer) if you drew a straight line through the curve it would be flat, so the derivative is 0, which is why we don't notice massive light changes around the summer soltice.....

i think this is the only time in my life except during carpentry when math has come in handy. god bless mr. ferrel.

piece of shit program, foiling my beautiful asci text graphic because it cant understand fucking spaces and enters.

can you post an image of sine wave with point a at 0, point b at pi/2 radians, c at pi radians, d at 3pi/2 radians and e at 2pi radians? thanks man.

If you can find it or render it, I can post it.
