Traveling through the Rockies feels rather dwarfing too.

Einstein, Gödel,and the reinvention of time—how the rise of relativity revolutionized our understanding of existence

Comment by Doone on June 10, 2017 at 8:01am

Ultimately, I learned that raindrops act not only like a prism, but also like a mirror. A mirror is typically a pane of glass to which a silver backing has been applied. Light passes through the glass, reflects off the silver backing, and then passes through the glass again. A raindrop does not have a silver backing (even though a cloud is metaphorically said to have a silver lining) — but some of the light does indeed reflect off the inside back surface of the drop. So in that respect a drop of water is indeed like a mirror. But as the light enters the drop, the angle of travel is bent (refracted) by the change in material. As the light exits the drop, after reflecting off the back, the path of travel is bent again. Different wavelengths of light are bent slightly differently, which causes the colors to separate. So in that respect the drop is like a prism. The angle between the beam that enters the drop and the beam that exits the drop is approximately 41 degrees. The angle ranges from 40 degrees for violet light to 42 degrees for red light. The other rainbow colors fall between these two extremes.

My dentist told me to use (sodium bicarbonate) baking soda to brush my teeth. He said the alkalinity (Ph) from the baking soda neuteralized the acid from bacteria. He said baking soda is better than tooth paste.

He also recomended using sativa lozenges and gum throughout the day because bacteria eats the sativa rather than the teeth.

Having allergies I tend to breath through my mouth. Antihistimines dry the mouth. My dentist said to take antihistimines  so I can breath through my nose rather than my mouth and use use Dentiva lozenges at night to keep moisture in my mouth.

Richard Feynman's book

"Surely You're Joking, Mr. Feynman! (Adventures of a Curious Character)"  is a fun read.
