A follow on to yesterday's "Biking to the Moon".
Explanation: How long would it take to drive to the Sun? Brittany age 7, and D.J. age 12, ponder this question over dinner one evening. James also age 7, suggests taking a really fast racing car while Christopher age 4, eagerly agrees. Jerry, a really old guy who is used to estimating driving time on family trips based on distance divided by speed, offers to do the numbers. "Let's see ... the Sun is 93 million miles away. If we drove 93 miles per hour the trip would only take us 1 million hours." How long is 1 million hours? One year is 365 days times 24 hours per day, or 8,760 hours. One hundred years would be 876,000 hours, but that's still a little short of the 1 million hour drive time. So the Sun is really quite far away. Christopher is not impressed, but as he grows older he will be. You've got to be impressed by something that's 93 million miles away and still hurts your eyes when you look at it!

Newton proposed “particles” and Huygens proposed “waves.”
In the end, I think that they agreed with each other.

Newton seemed to be a shy, retiring type. From what I understand when ever any of his thesis were challenged he just withdrew into himself and his solitary studies.

I'm driving to the sun in my Subaru Outback.
I'm confident that boxer engine will get me there and with decent gas mileage.

For that million hours to be realistic, you’ll have to avoid the 405 freeway in L.A.; otherwise, all bets are off!
