Trade offs Between 42.5°N 83.1°W and 12.9°N 77.5°E

First does anyone know what the numbers above mean??? Think hard… Think back to science class… Latitude, Longitude, equator… Is it coming back to you????

The numbers above are the latitude on longitude coordinates for Rochester Hills, MI and Bangalore, India. The interesting thing to note is the position relative to the equator…42.5° vs 12.9°. Stay with me… Basically Rochester Hills is half way between the north pole and the equator, with the north pole being at 90° and equator being at 0°.

I know you are thinking… So, what does this all mean.

Well… If you take the distance from the equator and understand it in terms of the earths rotation around the sun… it impacts the length of the day (sunrise/sunset). Here is where I am going with this… In Rochester Hills, MI you had the beauty of enjoying long summer days where the sun would be out for 15 hours (well past 9pm at night), and in Bangalore the longest day is only 13 hours… and the shortest day is 9 hours in RH and 11 hours in Banglore…

Basically being close to the equator has its tradeoffs. Closer to the equator means very little difference in sunrise/sunset times all year..so it gets dark between 5 and 6 PM all year long…but the plus side....is it warm all year round!!

So in January, I can rub it into all of you that it is 80° and sunny, and in July you can rub it in to me that it is 80° and sunny at 9pm at night!!!

This whole ‘getting-dark-by-6pm’ business is a little difficult for me. Most of you know what happens to me…. It makes me sleepy earlier…

How was that for a little science lesson....
