Reflections on a Two Year Old

December 25, 2016

Babysat my two year old grandson three days this week. He is an amazing creature and I suspect all two year olds are.

He learns at an astronomical rate. He bounces from joy to despair to joy again in a few seconds.

When his family – mom, dad, brother – are not around, he asks about them constantly.

He loves animals.

He asks why incessantly.

He runs everywhere. What age do we stop running?

I could go on and on and on and on but after three days with the little angel I’m really tired.

Summary, It’s a shame we grow up


Gravity vs. time vs. Age

December 12, 2016

According to Einstien’s theory of General Relativity gravity slows down time. That is, clocks tick faster on GPS satelites than they do on the Earth. Clocks on the surface of the Earth would tick faster than clocks on the Sun because the Sun has more gravity. The greater the gravity the slower the clock ticks

Based on my experience, a data point of one, age makes clocks tick faster. Clocks tick much faster now that I’m 70 than when I was 16.

Why didn’t Einstein include age in the theory of General Relativity?
