Is there a reference list anywhere where I can look for the meaning of a weird physics symbol when I run across one? For instance there is a thing that looks like a sideways capitol M. (There are two of them in the new PF banner to the right of Einstein's face.) I ran into this sideways...

have you ever taken a portable phone (i have a hunch that a mobile would work too) and (when it's not on or anything) ran the ear-end (the end with the antenna) across your computer screen? it makes a weird sort of electric shadowy thing...what's happening? :confused: [i should mention that...

weird situations that uve been in. My best was sitting in the middle of a slough trading estate in a carpark on an abandoned sofa in the blazing sunshine in the middle of febuary smoking a doobie :smile:

Okay, here's a popular claim. http://forteantimes.com/articles/178_backwards.shtml There is a similar gravity anomaly right in the middle of Knotts Berry Farm - an amusement park in Buena Park, California. IMAGINE THAT!

Got a question about something that happened to me today, hoping someone might have an answer that might explain it. I went to get a bottle of water from the fridge that is out in our porch where there is no insulation from the outside. In New England it is very cold about -5F today. I opened...

Which of the following is an equation of a curve that intersects at right angles every curve of the family y = 1/x + k where k takes all real values? a)y= -x b)y= -x^2 c)y= -x^3/3 d)y=x^3/3 e)y=ln x

What is the smallest integer greater than 1 that leaves a remainder of 1 when divided by any of the integers 6, 8, and 10? the answer is 121... how do you do this problem?

A Weird Idea Greetings. I have this idea, i know it is not really good (i already realized some of its weakness), but i thought i will put it here, since i believe that as it gets discussed (if it will) i might learn sth new. Ok, my idea is like a new way to make world-wide communication...

Hello, this is my first post, been lurking here for awhile. I made up this physics problem which involves a particle in 2-D. The particle has an initial velocity (Vo) or initial kinetic energy (KEo) launched at some angle. Once the particle is fired the only forces acting on it are air...

[SOLVED] This seems kind of weird, but...is there really no such thing as gravity in Hi, I was just wondering about this because...you see how there's supposed to be no gravity in space, but i sort of think there is because of the movement found within our glaxay and our entire solar system...

Do you know the Complex Plane? Quaternions aren't such a pain! Do you sing soliloquies Concerning Reimann Geometries Of balancing your Tensors, Spinors and Complex Vectors? Phase Spaces! Hilbert Spaces! Oh, so many, many wacky places! This is an open-ended thread dedicated to the...
