    Axion signature in the presence of strong magnetic fields?

    I really have no knowledge of particle physics, unfortunately. I haven't really had the urge to learn more until reading that article. You mind if I ask you what is a pion and how it interacts? (I'm actually doing QM homework right now, or else i'd read up myself :P )

    Axion signature in the presence of strong magnetic fields?

    So there was this article published today that some researchers may have found a dark matter signature emanating from the sun in the form of xr-ray emission from axion interactions with Earth's magnetic field. Article...

    Astrophysics senior looking into Aerospace Master's

    I think that's what I'm having some trouble with. I can tell you all sorts of specific research areas to do with astronomy, but i haven't really done my homework learning active areas of research with AE. Any resources you could point me too?

    Astrophysics senior looking into Aerospace Master's

    Yeah, I'm planning on taking that pretty soon, so I guess that'll help quite a bit. What do you think about going mechanical vs aerospace?

    First semester course load advice

    Keep in mind, just because a class is easy does not mean you won't have to spend much time on them. Phi 101 will more than likely require you to read quite a bit of material nightly. The essays and the debates may be easy, but they will still be time consuming. Always keep that in mind

    Astrophysics senior looking into Aerospace Master's

    Let me firstly and quickly apologize if this topic has been covered before. I know you all answer a lot of these questions, so please link me to some past discussions as you see fit. I am going into my last year as an astrophysics major, and I'm a bit dismayed at my job outlook with just a...

    Find the torque of a rotating sheet and the upper bound of the torque

    I guess I really wanted a more finite answer, but that's not always true in physics. My derivative ##\rightarrow 0## when ##a \rightarrow \inf##, which mean this sheet starts to look like an infinitely long and thin line along the axis of the diagonal and the angular velocity vector. Solving...

    Schools Majoring in physics at a lower tier university/career options

    As an undergraduate also studying physics and astronomy at a school that is not exactly recognized for its physics and engineering programs, what I can tell you is that you should plan to be sprinting right out the gate. Don't feel you've dug yourself a grave by going to a school of lesser...

    Find the torque of a rotating sheet and the upper bound of the torque

    Looks like I'm still running into a problem. When I plug in everything, it simplifies to this. then when I take the derivative. I can't solve for a in this answer. Could my initial ##\tau## be incorrect then? edit: I've solved and resolved this solution by hand a few times now and I keep...

    Find the torque of a rotating sheet and the upper bound of the torque

    Dam. You are completely right. So i basically would make ##\phi = \phi(a)##, and take the respective derivatives. What I'm wondering about this is that since for example, ##sin(\phi(a)) = \frac{b}{\sqrt{a^2+b^2}}##, could i just say that ##\frac{d}{da}sin(\phi(a)) = cos(\phi(a))...

    Magnetic Vector Potential and conductor

    Homework Statement Show that, inside a straight current-carrying conductor of radius R, the vector potential is: $$ \vec{A} = \frac{\mu_{0}I}{4\pi}(1-\frac{s^2}{R^2}) $$ so that ##\vec{A}## is set equal to zero at s = R Homework Equations ## \vec{A} =...

    Finding flux from apparent and absolute magnitude

    Is there not some way to manipulate the flux ratio so that you can calculate the fluxes of each star?

    Finding flux from apparent and absolute magnitude

    But what if the absolute magnitudes and distances of those stars are known?
