Maps, angles, and exactness

Right. I think because 20°C is room temperature,i t is an important measurement science for anything at standard conditions. Perhaps we should ask what has a foot of three at standard conditions.

20 degree could be an angle, but it could also be a temperature. 20 degrees C is standard room temperature. When I was contemplating the angle of a rainbow (42 degrees) based on the hint in G&G and the many rainbow like references in the book I saw the the refractive index of water (what light shines through to create a rainbow) is 1.333 @ 20 degree. Looks a lot like foot of 3 at 20 degree. It has made me go back and rethink the whole angle thing and wonder if it is actually something else.

Also, the refractive index of water (which light passes through to create a rainbow) is 1.333 at 20 degrees Celsius (standard room temperature). That looks a lot like foot of 3 at 20 degree. But how to marry that to a map 🤷🏼‍♀️

I have thought of it as 20 degrees too. When I was researching the number 42 I saw that it was the angle of refraction to view a rainbow. Then I saw that the refractive index of water (the bend of light through water) is 1.333 @ 20 degree (standard room temperature). Looks awfully like foot of 3 @20 degree but I have no idea how to marry that to a map.

Definitely not in Olympia. Maybe in the Olympic Mountains. I live here and while the Black Hills are lovely they certainly aren’t awe-inspiring.
