When the sun's rays break through a cloud there appears a radiating pattern but if one drew a line through these rays they would meet much closer than the distance to the sun. How come?
Is the visible light on the surface of Pluto equivalent in intensity to what it is on Earth? That is, is 1 lux = 1 lux even though it takes light that much longer to get there from the sun? Or are images of distant objects in the solar system taken with longer exposures?
Hey well neither do I, that's why I'm at the collective brain otherwise known as Physics Forum. The technique is well known and comes with the instructions for the resin so it's no strange oddity.
I've had several discussions relating to how bubbles of air trapped in resin during the mixing process are drawn to the surface by blowing onto the surface with a straw or by passing carbon dioxide from a propane burner over the surface. How do the bubbles of trapped air even know that the...
I have had this sensation and was trying to describe it to someone today and it's how I ended up here. There are few things however that I had that were not mentioned by anyone and I wanted to know if anybody else had had these symptoms/sensations as well

So are you saying that these circles are in fact images of the sun itself caused by the individual palm fronds cross crossing and creating many small square holes which act as pin hole. This does not make sense to me as the holes are too big to act as a lenses. Also if they were images of the...
I ended up here trying to find out the very same thing. I also have a window facing west and was looking out a window that was somewhat dusty. The light from the low sun was diffracting through the palm trees and creating many perfect circles of light each one was about 30 millimeters.
I did...
