Blogging at Mach 1.3

Dovetailing on my "Big Planet, Small Minds" blog posting last week. Just think about the numbers for a minute.  The Earth is roughly 7900 miles in diameter.  To find the circumference we simply multiply the diameter by PI (3.14)

7900 x 3.14 = 24086 miles in circumference.

Considering the fact that the day is 24 hours long, or, it takes us 24 hours to make one revolution around the circumference.  We are travelling at over 1,000 miles per hour this very instant.

Imaging Real Estate at 1,000 miles per hour.  Now that is fast.

Mach 1 at sea level is 761.2 miles per hour.  1,000 miles per hour roughly calculates to Mach 1.3.

Just think that if it takes you 3 minutes to read this blog, you are 50 miles from where you started reading this blog.  We travel at about 16.6666 miles per minute.   So you could easily get from Alameda to San Leandro in one minute, providing the Earth rotated in that particular direction.

This number does not take into account the motion of the Earth in it's yearly orbit around the sun.

I should issue you a speeding ticket.

If I could just jump higher.........wait, there's that whole inertia thing........actually, I never did real well in physics........:)
