Since a proton is made up of three point particles, doesn't the proton system have a real volume? If not, then what does have volume?

Ugh, as long as it's not another particle in a box.

I really do like this explanation. I am also trying to think of HUP in the most concrete way possible, and I stumbled upon this thread and read through it. I'm wondering if you or anyone else can clarify some aspects of this explanation. You write that: This is sort of what I was thinking...

Hi all, I'm attempting to get a feel for the different mechanical measures of a material, e.g., strength, toughness, stiffness, etc. I'm looking around, and I can't seem to figure out where a measure of stretchiness would fit in, that being how much a material will actually stretch or deform...

I've been reading up on neutrino oscillations and I have come across this issue. I know that oscillations are dependent on the mass squared differences of the mass eigenstates, which is why determining things like the absolute masses of the eigenstates and the hierarchy of the eigenstates is...

Homework Statement I'm wondering whether or not it is possible to get the area of the base of an elliptical, non-right cone if the following two parameters are known: - length from center of ellipse up to vertex - angle that the sides make Here is a simple visual...

Indeed I have thought about it. I had quite the experience at a New England boarding school, and teaching at my old high school wouldn't be half bad in my opinion. Teaching in high school has always seemed like a fall-back position though...perhaps I should look at it more seriously. I guess...

Do you know of any well known atmospheric sciences or other Ph.D programs that I could look at to see if it looks like something I'd be into? I have taken a few anthropology courses and indeed the archaeology course I just finished touched on a lot of these topics. I suppose I'll look into...

Scientific journalism is a relatively new concept to me. I actually say a flier at my school for MIT's graduate program on the subject: http://web.mit.edu/sciwrite/index.html It seems interesting, though I don't know I'd be happy in that field. In high school I volunteered at a zoo for 4...

I am currently a junior at a 4 year university and I will be graduating in the spring of 2010 with a BS in physics. I'm having a very hard time deciding what to do after I graduate, so I thought I'd ask around for ideas. My problem is that I have a lot of interests, but I don't know how to...

I was asked this today, and I cannot picture an answer. Say you had a long bar in a vacuum, billions of miles long. If a force was applied lengthwise on one end, would the other end immediately respond? Would reference frames matter in this instance? I know information cannot travel faster than...
