    Why Is the Fringe at the Narrow End of a Wedge Always Dark?

    For a solid wedge of material of length L and maximum width D (ie, a triangle) how would one obtain an equation for /\x, the distance between dark fringes? For wedge fringes, how come the fringe at the narrow end is always dark?

    Programs What to do with a Physics Degree

    Computational physics is a huge field. Simulations and whatnot. In fact, it's mandatory to take a computational physics module in year 2 at the uni I visited.

    The Physics Behind Optical Mouse Technology

    There's a program (readmouse) that dumps the little pictures that the mouse takes. Heh heh.

    Mathematics Course Outline for Pursuing a Career in a Third World Country

    Well, mathematicians can generally take up many jobs that require problem solving and maths skills. He doesn't necessarily have to work in Physics, but many mathematicians at the moment are working on particle physics research.

    Programs What to do with a Physics Degree

    Ditto, but physicists are in a huge variety of jobs. Don't be scared off by the stereotype that they sit in stuffy rooms researching things. I was at a university open day the other day and one of the physicists there worked for IBM and worked on practical application projects at the university...

    How do the casters on a turntable support the weight of a motorcycle?

    It's a no-brainer if you think about it. Pressure = Force/Area Where Force is the weight of the bike (500 x 9.8) and the area is the area of tyre/bike touching the turntable. The pressure's not applied uniformly.

    What are some tips for improving a friction experiment?

    I started working on my project for real at school today and I have no idea if it really is a good project. It seems very arbitrary and messy somehow. I've got two experiments to explore friction. Ff = Frictional force. Fg = Component of force acting down parallel to incline Fn = Reaction...

    What is the formula for the 3D trajectory of a curving ball?

    You'd definitely have to begin by splitting the problem into its x, y and z components and working from there. Think about projectile motion, etc. Anyway, you haven't given us enough info. Does it start from rest, is it moving, accelerating?

    Hi 2 Simple everyday things that I dont understand. Please help? Taps and vaccum

    This doesn't explain why the water is weak-flowing when the tap is only slightly open and strong-flowing when the tap is wide open. If it worked the way you've explained it, wouldn't the water flow out really strongly when the tap was open slightly (like putting your thumb over a hose) and...

    How can someone achieve invisibility?

    A science fiction story? Go wild! We don't read SF novels to see how plausible something would be.

    Can Wormholes Enable Time Travel to the Past?

    Wait, I want to know something. Does the time-machine move with the user or does the user 'step inside' and get transported to the time-machine in the future? In that case, say the user stepped inside in the year 2000 and wished to travel to the year 3000. What if the time machine was destroyed...

    Questions for Pre-Med Student at University of Pittsburgh

    Never feel you're too low for anything (as long as you're not too rubbish) and just go for it. You either get in, or you don't. Taking a bio-engineering minor could be useful, depending on which area of medicine you plan to focus on. Bio engineering and chemical engineering could put you into a...

    What are the properties and behavior of photons?

    At least you're posting something useful. I still need to start thinking in terms of equations. But anyway, what was the question again? :P

    If time was stopped, is inertia conserved?

    If you think about it, when you 'see' something, it's all about light hitting your eyes. So if time stopped, light would no longer travel and you would (of course, this can't happen as time's stopped for you as well) see nothing. I'm probably horrible wrong, but oh well.
