    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...

    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...

    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...

    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...

    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...

    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...

    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...

    Ah yeah mathematics girl. I'm like ##e^{2x}##; you can differentiate me all night long, and I only get bigger.

    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...

    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...

    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...

    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...

    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...

    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.

    Should Algebra Be Required At Community Colleges?

    What do you propose as a solution to the problem if not replacing intermediate algebra with something else to, as you suggested, work out the mind? Or do you believe these numbers for CC graduation/transfer rates to be sustainable/acceptable?

    Future market restructuring needs to be taken seriously

    Nobody seems to have given much discussion to what should be done if low skill jobs see a dramatic downturn. Russ and others have said some things, but nothing fleshed out as to what to do with the unemployed in the worst case scenario. I'd be curious to hear what others think about a situation...

    Courses Calc III and Solid State Physics courses in same semester?

    It all depends on how you manage your time. My object oriented class took me 5-10 hours a week. Calc 3 took me 10 hours easy. Electronics and SSP can both take similar time scales. If you think you can put in 40-50 hours a week plus class time without getting burned out go for it. If not, you...

    Studying Prioritizing classes without sacrificing quality

    This is bascially how I feel about it. It takes a little sifting, but ultimately can be very useful at picking out a good professor, and can be less useful in identifying a bad professor.

    Programs Should I or Should I not pursue a postgraduate degree in physics

    This question gets asked here once every week or two I think, lol. So first, a good bit of advice is to take a look at other posts and see how our veteran posters respond. It's usually good advice. I assume you would be considering pursuing a PhD in Physics. You'll still have plenty of...

    Studying Prioritizing classes without sacrificing quality

    I always take the negatives with a grain of salt. But when I see a prof rated above average >2.5, the advice tends to correspond very well.

    Courses Mechanics / E&M / Multivariable Calc / Diff EQ Self Study

    To add to this: MITocw has video lectures for all these courses. And practice exams as well. Although the physics lectures are on youtube under a different channel. Search for "walter lewin 8.01" for mechanics.

    Studying Prioritizing classes without sacrificing quality

    I know this may sound silly, but go onto your university's subreddit if it has one and ask about manageable gen-eds. Or just ask other students in person. Or just look for something interesting to take and investigate the professor. It's most modern day students bread and butter to check...

    Should Algebra Be Required At Community Colleges?

    Imagine you got a GED, now imagine you waited 5-10 years after you got that GED to go to college. That's a very common story in CC's. Transfers in my school aren't as common as Cali. I think of the thousands of students we have only a handful make it to a 4 year school. I need to look up...

    Should Algebra Be Required At Community Colleges?

    I feel like some healthy conversation is happening here, but let me highlight something some in the discussion seem to not understand: CC's are not meant to be like universities, or high school, or anything else. They are their own thing with similar but different goals about educating. Many of...

    Should Algebra Be Required At Community Colleges?

    I think we agree when it comes to that quote and it's meaning. However, again, I would like to emphasize that whatever value you seem to perceive as being taken away by reducing the math requirement, can easily be amended and then some with more pragmatic skills being added as a graduation...

    Should Algebra Be Required At Community Colleges?

    Now we're getting somewhere. I am curious then, not in a passive aggressive way, how you see the role of education. And if you believe that the role of education is to be highly competitive and difficult to achieve, what do you suggest that low skill workers do to gain the skills to move up the...
