1. ### Proof: 0.9999 does not equal 1

The function y=1-1/x is often used to show how the repeating decimal 0.9999... is equal to 1. When x=1, y=1; x=10, y=0.9; x=10000, y=.9999, and so on. The limit of 1-1/x as x approaches infinity equals 1. An assumption is often made, however, that if the limit of an expression as x approaches...
2. ### Classical Physics with Time going Backwards

First, what does it mean for time to be going backwards? Basically, any time there is a reference to time, we just need to negate it - so time will have a negative effect of what it usually would. Velocity (1D): There is an object that moved from A to B in time t at a constant speed. If we...
3. ### Distribution of Primes

I made this simple program to list all non-primes (ignore the first row and column of the output) and list what I call "important numbers". I have attached an output if you don't want to bother running and compiling the program. #include <iostream> #include <fstream> using namespace std...
4. ### Excluding Evidence contrary to Theories

Recently, a thread here was closed because it linked to an experiment that seemingly conflicted with the currently accepted theories. While the majority of people agree with these theories, I think it is an injustice to censor evidence that is contrary to a theory - otherwise human knowledge...
5. ### Wavelength in Orbit

Have a look at this diagram I made: http://la.gg/upl/wavelength2.jpg [Broken] The scenario is that you are in circular orbit around the Earth and a radio signal is sent from the center of the Earth. If you have a clock with you that is synced up to a clock on Earth (we are ignoring relativity...
6. ### C/++/# C++ Matrix Solver

I just thought I'd post this here. It will help you solve a matrix by getting it into row-echelon form (well, close to it anyway). I avoided global variables and tried to make it as expandable as possible. #include <iostream> using namespace std; void output(int height, int width, long...
7. ### Blueshift + Classical Physics = Golden Ratio

I was doing calculations to see how far classical physics would take us in terms of the speed of an object never exceeding the speed of light in a reference frame. Here was the scenario I set up: http://la.gg/upl/light.jpg [Broken] So, if we want to find the time it takes the light to get...
8. ### Diffusion of Different Gases/Particles through Air

If something like oxygen were to be released into a room, it would diffuse much faster than something like a heavy smoke. Has someone ever measured the rate of diffusion of different gases and particles? A quick Google search turned up nothing. I'd like to know the distribution of how many...
9. ### Drag can happen in extremely low-viscosity fluids

First, let me introduce myself. I am new to these forums, but not new to sharing ideas that cause argument. If you think anything I say is wrong, please speak up. The reason I joined was because of this outrageous 2+ year old thread: https://www.physicsforums.com/showthread.php?t=70227 The...
