Global Civilizations

The intent of this blog was to show my progress studying the content of the Global Civilizations curriculum I helped produce in 1992. I expected to update it with current examples from my life as time went on.

About Me

My Photo
Name:
Location: Las Vegas, NV, United States

We have been gardening together since the fall of 2001. John sifts the soil and Lee grows the greens. We prefer greens and roots in the winter and harder stemmed veggies in the summer such as peppers and cucumbers. John looks after his worms and tumbles compost. Lee tracks the seeds and the work schedule here in the northwest Mojave Desert.

Right Ascension



Here is a photo of my Solar System Calendar Clock set for May 2, 2012.  The blue disk is now properly Venus (and not the moon).  The Right Ascension (RA) measurement is reduced to a 12-hour clock and centered on the earth (yellow disk).  My RA values were computed from NASA's Horizons ephemeris generator.  You can see the right hand portion of my notes under the transparency. 

I have also added a line drawing of the same photo for easier printing, if you like.

I know. It's not very clear. Working on it.
