    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

    A couple of different variables arises right away such as wind, the height from which they are dropped, how level the ground is, what type of ground it is, how much deviation from a complete horizontal drop you have, how many marbles you use, what material they are made off, if the cup is at...

    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...

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

    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...

Not everyone is like...

    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.

    Hydrophilic vs hydrophobic

    It really has no relevance which of the descriptions one chooses to use - they are both almost equally wrong. It has nothing to do with the substances not 'wanting' to be close to the water or the other way around. Prof. Robert A. Weinberg gives a better view of it in the fourth video...

    The promises of promiscuity

    To my knowledge, promiscuity is seen to a greater extent among males in the animal kingdom than among females. Since most females carry their offspring in their own body, finding a good mate is imperative, since the only get one 'shot' at producing during that season. A male of the same specie...

    Jews in science

    If I'm suppose to speculate about why a certain group of people have a higher number of Noble Prize awards than others, I'd say that the 1930s/1940s may or may not have a substantial contribution. After performing a Google search, the first page of hits all give different information about the...

    Why no optics subforum?

    In my opinion, most discussions have to do with different principles behind a cross-forum subject such as optics. These principles are usually confined to one of the forums in the physics or engineering category. I agree with vanesch that having as low number of forums as possible is a good...
