    Does anyone know how charlie (from numbers) was able to determine the

    Ok, how if I rephrase the question like this: "What will effect the marbles when dropped from a cup from a level table indoors(?)". It isn't hard to figure out. There isn't any wind indoors, nor can the marbles land one billion meters from the cup either. What can possibly effect the spread...

    Does anyone know how charlie (from numbers) was able to determine the

    The first thing you need to do is to find an appropriate axis and put down all the torque effecting that point both clockwise and counterclockwise. Remember that the scaffold exerts its from the center of its mass.

    That particular episode used a lot of variables that may or may not be purely scientific - assumptions were made that serial snipers do not attack far from home, where he or she 'feels comfortable'. I just realized that I am now describing the episode where the initial sniper lead to other...

    Should a physicist learn math proofs?

    I agree that physicists does not necessarily have to know the proofs for mathematical theorems to function in that particular profession. However, it will not harm people to review it if they are interested in it or simply wishes to. Whether that experience will actually lead to becoming a...

    Well, he probably used some of the reasoning for motion in two and three dimensions and made approximations with the help of other variables such as wind and so on. Think about it. What will go the longest distance - water traveling against the wind or with no wind at all (assuming a...

    C/++/# Hiiii,I want forums about c++ language. I am studying this language

    You probably need to read some documentations instead of only a forum. How far have you come? I've found Devshed to be an excellent resource, both as a forum and for having documentations.

    Why warm air raises?

    Yes, Archimedes's Principle work with gases as well. The fundamental physical property behind it is density. As hot air contain atoms and molecules with higher kinetic energy than cold air. As a result it has a lower density, and the cold air goes downwards.
