Today you are You, that is truer than true. There is no one alive who is Youer than You.” Dr Seuss

Another beautiful sunny day, in a picture perfect week. Perfect weather, warm during the day (temps in the 80’s), cool at night (temps in the 60’s). Spent the day in the park, watching the kids and squirrels play. Mediated at a beautiful little chapel on what a great place I am in this life, in this world. Today’s mantra – beautiful, beautiful, beautiful.

The art of Physic

Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and (seemingly) random motion.

The apparatus was built from a design published by Richard Berg at the University of Maryland. The particular apparatus shown here was built by Harvard’s Nils Sorensen.

The period of one complete cycle of the dance is 60 seconds. The length of the longest pendulum has been adjusted so that it executes 51 oscillations in this 60 second period. The length of each successive shorter pendulum is carefully adjusted so that it executes one additional oscillation in this period. Thus, the 15th pendulum (shortest) undergoes 65 oscillations.

Monday is Memoral Day here in the US. It’s designated an offical holiday, but it is anything like a holiday for me. It is to honour the memory of those who sacrificed their lives for their country. There is honour in sacrifice, but war is the least honorable activity we humans take part in that I can think. I myself took part in war. Those memories only want to make me cry.
