    Can Santa Be in Multiple Houses at Once, Just Like an Electron?

    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?

    Can Santa Be in Multiple Houses at Once, Just Like an Electron?

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

    Trying to understand Heisenberg Uncertainty Principle in a physical sense

    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...

    Different mechanical measures of a material

    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...

    Question Concerning Neutrino Mass Hierarchy

    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...

    Irregular Cone Geometry Problem: Finding the Area of an Elliptical Base

    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...

    Help me brainstorm ideas regarding what I want to do with my life

    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...

    Help me brainstorm ideas regarding what I want to do with my life

    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...

    Help me brainstorm ideas regarding what I want to do with my life

    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...

    Help me brainstorm ideas regarding what I want to do with my life

    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...

    Long Bar and the Speed of Light

    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...
