  1. Maybe there is more anti-matter than matter but we have chosen to call anti-matter: matter and vice-versa.
  2. Turning the piece of paper is a simple rotational change in the coordinates of the system. However I could apply a transformation matrix to a system which changes the shapes of lines. If you look in a calculus or linear algebra book there will be an explanation of different types of transformation matrices.
  3. From your diagram we can see which line is shorter, however if I would apply the right transformation to the lines I could make the other line shorter. My transformation could be the way the other person witnesses an event and this would lead us once again to a paradox.
  4. The idea is that all of the multiverses exist and we are in all of them but everytime we make a decision we take a measurement of sorts. It is that decision which collapses all of the multiverses of the future that share that moment into one.
  5. Go here: http://www.pasco.com/ They sell all kinds of scientific lab equipment.
  6. If you want to use the computer as an example than it would work. The reason you could use it is that if the computer is in the other room and you know that there is a probabilty that the computer gets a 1 or 0 than thats all you have is a superposition of the probabilties of 1 or 0. When you open the door and look at the computer than the superposition of probabilities collapses to one of the two outcomes, just like the cat is alive or dead before you look in the box.

    Equation

    I'm looking at these websites and apparently I am missing a step, but I would appreciate it if you could show me the proof you used to solve this problem.

    Equation

    What is the point of that substitution? Where is that taking us. I see that if you substitute iz for z we get the sin(iz)=sinh(z)/i, but I don't see how this gets us to sin(z)=i, and there is no mention of the z=x+iy.
  9. A book I read that was helpful with black holes is Black Holes: A Traveler's Guide I t gives a lot of useful information, including equations and some simple programs.
  10. Another example you can use for this is go to radio shack and get the piezo electric buzzers (or however you spell it) and hook them up so that they are in parallel, but hook the red wire from one to the black wire of the other. When you do this you can set them a integer number of wavelengths plus a half wavelength and they will interfere with each other and you will not hear the buzzing. Found that out accidently in a physics lab once.
  11. If you break it down into matrices you can use a transfer matrix to shift it. Look up linear algebra and transformation matrix on wikipedia or something and see if that info helps you. If you post a few more details about it here maybe we can help you figure it out. The problem sounds to me like a vector addition problem where one of the vectors is changing.
  12. a laser is not required for interference. The original experiment was done with a candle and if you do it right you can see a interference pattern from look at a light sourse through the small gap between your fingers. try it with your index and middle finger.
  13. units shouldn't matter as long as you are consistant throughout.
  14. yes, but there is still interference.
  15. This problem is not outside the scope of high school physics. If you haven't been shown how to do this in high school than your teacher is falling down on the job.
  16. You are off by a factor of 100 somewhere.
  17. There is interference but it isn't distiguishable. Each wavelength has its own pattern and they all overlap each other.
  18. you forgot the second it takes for the police car to start accelerating.
  19. two objects in different frames do not have the same second. as far as the observer, runner, belt cenario goes from the perspective of the observer the clock on the belt would be running slow while the clock on the runner is keeping time with the clock held by the observer. In the frame of the belt both of the other clocks would be running slower and the runner would see the same thing as the observer. This is because the observer and the runner are not moving RELATIVE to each other.
  20. Time dilation is caused by velocity the relativistic part of the equation is the [math]\gamma=\frac{1}{\sqrt{1-\frac{v^2}{c^2}}}[/math] so it is the ratio of velocity to c that causes this effect.
  21. I don't know if I would call it meeting but I talked to Kevin Smith the other day. I was waiting in line to take a teacher certification test and he wondered over from the comic-con that was going on in the convention hall next to the one I was taking my test in.
  22. Try this equation: [math]b=\sqrt{\frac{a(d^2-a^2)}{a-1}}[/math] It should work if you want I can explain where I got it from. Are you graaphically representing the orbit or just giving numbers? If you are going to be creating a program which graphically representss what is happening this is not the mathematical approach that I would suggest.
