Cant seem to find information on this anywhere... If I want to average two values with errors, say x1 = 10 +/- 2 x2 = 12 +/- 4 I would do a regular weighted average that would reflect the fact that x1 is a more precise measurement. But what if my errors are asymmetric? So if I had...

When I look at a nuclear level scheme, there are many gamma ray transitions from energy levels of say, spin 4 to spin 2. However, my understanding was that photons carry spin 1, and so conservation of angular momentum would say that you can only change the spin of a level by 1. What am I missing...

very cool...someone needs to build a track that starts normally and then curls upside down so I can see this in action.

some other ideas: -simple kinematics, acceleration times, things like that -softening of the tires due to temperatures caused by friciton -the way the cars are designed to give massive downward force (kind of like an opposite wing)

In my experience as a nuclear physics MSc student, any intense computational stuff can be done on a computer in the lab/office, so in terms of raw computing power there is no need to spend too much. There are two things you may want to keep in mind: 1. You'll probably want to run a linux...

Two thoughts: 1. "Doing math/physics" and "giving back to society" are not mutually exclusive ideas. My father used his math degree to teach at a community college, and over the course of his career has helped hundreds of students find their way in life and become successful, confident people...

There were a number of reasons I started the masters, but I think a lot of it was following the crowd after graduation. It seemed to be "the thing you do" after a BSc in physics. And I do have a project lined up, but its still in its infancy at this point. The "escape" plan you talk...

Hello I am a first semester Master's student in Canada, and I'm giving serious consideration to quitting. My main reason for considering this is that I simply do not enjoy what I am doing enough to put in the work necessary to be successful. My question is whether anyone knows of any...
