1. ### Engineering Questions about applying for positions while I'm still an Undergraduate

I've been working for a company I helped start for the last 10 months. In that time I've built quite a powerful product, which has attracted recruiters on Linkedin to offer me their time. Some of them have been exceptionally tantalizing. Right now, my company is finding it's way to being able to...
2. ### Probabilities for two spin systems interacting in isolation

Generalizing to N total spins in A' with n being up and N-n being down and finding P-/P+, while simplifying some things, just produced too neat an answer for me to be happy with given the rest of the homework. I guess we got some easy problems then. No biggie. I'm so used to working in...
3. ### Probabilities for two spin systems interacting in isolation

When A points up the total number of states is 3, as A always remains +, and there are three combinations of two + and 1 - in A'. So P+ is 3/4 When A points down, we need to conserve energy, so all 3 of A' spins go to +. There is then only one configuration, (-|+++) so P- is 1/4 I did offer...
4. ### Probabilities for two spin systems interacting in isolation

Homework Statement Consider a system A consisting of a spin 1/2 having magnetic moment ##\mu_0##, and another system A' consisting of 3 spins 1/2 each having magnetic moment ##\mu_0##. Both systems are located in the same magnetic field B . The systems are placed in contact with each other so...
5. ### Other Books on Data/Error Analysis

I'm looking for a good reference book on data analysis techniques for science (namely physics) that has a lot of programming applications and some decent error analysis coverage. Right now I'm analyzing large datasets of telescope arrays and would like something to learn from as this is my...
6. ### Should Algebra Be Required At Community Colleges?

I've been thinking a lot over the last few weeks about this without posting. The main reason I posted was to be challenged, and maybe garner some ideas from all of you. I believe I'm more on the other side now in the following way: Community Colleges changing their curriculum, while pragmatic...
7. ### Stargazing Where's your favorite place to stargaze?

I'm planning a trip for next year that takes me to at least one place where I can get a good view of the sky with a telescope I'm buying this Christmas. I could just google "best stargazing spots" but I thought it would be more fun to ask you awesome people where you go when you want to get that...
8. ### Collection of Science Jokes P2

Integration is the pillow talk of mathematics :)
9. ### Collection of Science Jokes P2

Ah yeah mathematics girl. I'm like ##e^{2x}##; you can differentiate me all night long, and I only get bigger.
10. ### What should I expect from 1st year physics?

Picking up some details from elsewhere is all well and good, but you're going to do your best learning under the pressure of the course. It's not overwhelming if you really work hard. Here's what I suggest: 1. Pick up your textbook early and try out some of the problems from chapter 1 and 2...
11. ### Other Availability of funding within different areas of physics

Condensed Matter/Solid State is god right now at my school. Most funding goes there iirc. Particle is in decline at my school (we barely have enough to pay our undergraduates, and even then only some). Astro gets even less than particle (our department is half the size of particle or condensed...
12. ### Let's tell stories!

I find so many stories so interesting on here that I thought I'd start a thread where we tell each other our funny/interesting stories from life. They don't have to follow a common theme, just let loose about something! Preferably at least a few paragraphs in length. If it's just a paragraph...
13. ### Should Algebra Be Required At Community Colleges?

It's very good to hear that your experiences have led you to the conclusions in your first paragraph. Honestly, I was truly hoping that someone who taught at various levels of mathematics in the past would post here. I do feel as though everything you said is true, and have for the course of...
14. ### Schools Having a hard time deciding where to study physics

Minimize the debt that you personally take on as a result of your degree. That's your number one priority. Something to consider: depending on the state you live in here in America, you may be able to transfer to a 4-year school after 1-1.5 years of study at a CC. My school is one such school...
15. ### Future market restructuring needs to be taken seriously

This is my opinion as well. I am very interested in people like Russ' views who oppose most things relating to welfare and how, if the situation truly arose as predicted, they would help (or not help) the people without jobs.
