Here I thought the Equinox was wednesday – a supernaturally beautiful day here – mild, moist, breezes like a kiss on the cheek.

Turns out it was today, 9/23/11.

In our science illiterate society, it’s incredible how many people do not understand the reasons for seasonal change, much less the mechanism of climate change. NASA, as always, here to help. No wonder the Tea Party hates them.

1. it’s incredible how many people do not understand the reasons for seasonal change,

Since they learned it in the 2nd grade.

There are adults in America that do not know it takes the Earth one year to revolve around the sun!

I had my usual check up today and there was a poster on the wall of the examination room explaining that antibiotics would do nothing for viral infections, like the flu or a cold.

Pitiful.

2. 6am and 6 pm

From the NASA site: Equinox means "equal night" in Latin, capturing the idea that daytime and nighttime are equal lengths everywhere on the planet.

That is true of the Sun's presence above the horizon, though it does not account for twilight, when the Sun's rays extend from beyond the horizon to illuminate our gas-filled atmosphere.

I also like to think of the Equinoxes as the days that the sun rises at 6am and sets at 6pm everywhere on earth, except for daylight savings time and China which only has one time zone.
