Reverse Definition and 310 Threads

If time were to go in reverse, how exactly would the universe, and humans act? For instance, humans can think and be conscious while time is pointing in a forward array, but can humans be conscious while time is running backwards? That is what one would think, right? Would mathematics have to...

I have an equation, that I used in a software I made (Delphi). Now, I want to sort of "reverse" this equation. Y = 0-((( ClickedY * (1800 / PicHeight ))*2)-1800) X = (( ClickedX * (1800 / PicWidth ))*2)-1800 What does ClickedY = if you know Y and the PicHeight? what does ClickedX = if...

Someone mentioned this web page tangentially in a thread in Skepticism & Debunking, but it deserves its own thread here in GD. http://www3.telus.net/jefmil/stairwaybackwards.htm Everyone's heard the claim that certain songs contain hidden messages if played in reverse, but you (or at...

(Sorry, I'm testing with the 'tex' code) Reverse Gravitational Force is the opposite force of Gravity. It is it that keeps two bodies from not moving EXACTLY into the areas given by F=\frac {G_m_1_m_2} {r^2}... You can test it by using EXTREMELY precise instruments, and checking if an...

Help with reverse siphon break? Hey there, Not sure if this is possible but... I was wondering if there was a way to set something up so that one liquid would siphon into a lower container and stop when the liquid reached the level of the tube opening without using any sort of valve...

Ok, is there any solid, liquid, or gas that becomes heavier as it gets warmer and lighter as it gets colder? Like a reverse lava lamp. The little physics I know says no but I Know VERY little, you know? CJ

This is not a homework question but I am posting it here because I think it may be too basic for the other forums. I am looking for a ray diagram for a reverse galilean telescope (ie. + eyepiece, - objective, so image is minified). Can anyone describe what the ray diagram would look like or...
