    the opposite way (left loose, right tight)

    from Sheldon Brown's site (rip):
    "Track hubs have a stepped thread. The main thread that the sprocket screws onto is the same as that of a normal freewheel hub. Outboard of this, is another threaded secton of slightly smaller diameter. This thread is a left (reverse) thread, and a special lock ring screws onto it. After you screw the sprocket on in the normal manner, and tighten it down securely, the lock ring screws down so that it presses against the outer surface of the sprocket. If the sprocket should start to loosen up, it will try to turn the lock ring counter clockwise...but that only tightens the lockring. As a result, the sprocket cannot be unscrewed by the chain, no matter how hard you fight the pedals."

    From experience, it's best to consult his site first, as you tend to come away with more knowledge than you were initially seeking.

    the way i remember it is if the wheel is turning forwards, the cog is tightening. therefore clockwise is tighten, counter clockwise is loosen. switch that around for lockrings.

    Is very simple...the cog tightens when you pedal. You should be able to figure out the rest.

    turning relative to what? and when connected to a drivetrain or a chainwhip?
    I'm not sure why you guys are attempting to introduce multiple concepts when he's asking a simple question.

    Q: which way do you turn a cog to get it off?
    A: left. left is loose, right is tight.

    if the bike is in motion, connected to a chain, the act of riding forward tightens the cog. just trying to give him an understanding of why the threads are in the direction they are so he can use it as a mnemonic device in the future. like i said, counter clockwise is loosen.
