Hello, I'v been taking an interest to astronomical spectroscopy lately and I have some questions about that. In order to get myself going I wanted to get as much information about Sirius A and Sirius B using the distance, obtained by using parallax(I didn't do that but imagine I did) , and...

I've noticed this a lot, but I never though it was weird, so I'm deciding to ask PF. Every once and a while, I'll just be sitting around, bored or contemplating the universe, when I'll stare at a blank object and start seeing little tiny circles with dots in the middle. Kinda like a molecule...

Forgive me if this isn't the correct spot for this post. Since about 15, before I had tried any drugs, I always experienced bright color blobs, patterns, visual snow and movement in the dark, as well as grids across the sky (this doesn't happen often anymore). It always kind of made it hard for...

Visual Sensory "blank-outs"? Is it true that if you attempt to visually perceive something that is so strange and beyond your personal understanding, you will not be able to "see" it? In other words: If your brain doesn't already have that particular image stored somewhere and you try to view...

I am learning calculus and I liked the idea of how limits are represented visually, as a removable discontinuity (a single point gap) in a function of x. When we started studying derivatives I immediately came to the conclusion that a derivative is like a single curve "gap" in a function of x...
