    Pitfalls of Pursuing Physics: What to Know Before Making the Change

    [FONT="Times New Roman"][SIZE="3"]While physilab and twofish gave excellent answers to your question, I have some things to add that I think may be worthwhile. I'm a math major doing a combined BA/MA program. I know you asked about physics, but there are certain similarities. For me, math...

    On a lifelong search for the best writing utensils

    [FONT="Times New Roman"][SIZE="3"]I use Zebra pens mostly. I've had a variety: fine tip, ball point etc. and they're all really well made and write nice. I'm currently using a Zebra telescoping ballpoint pen. The best part about them is that they're thin! I hate thick pens, they throw off my...

    Question about Graduate Seminars

    [FONT="Times New Roman"][SIZE="3"]I've been to many lectures; given by visitors and Professor's colleagues at my own university, but I've never been to a "seminar". I was recently "invited" to attend some graduate seminars at a university that is not the one I'm currently attending.This is my...

    Question regarding letters of recommendation

    [FONT="Arial"][SIZE="2"]Thanks, everyone. I think it's best if I do what Choppy suggests, and at the end of the term mention that I'll be hoping to get a LOR when the time comes. Also, this question is in regard to a professor that is teaching a class I'm in. I've worked with two other...

    Question regarding letters of recommendation

    [FONT="Arial"][SIZE="2"]I was just wondering if one should ask a professor for a letter of recommendation right after the course finishes or when you're ready to apply to grad schools... The only LOR that I've gotten was after a course that I took just before I transferred to a different school...

    Why is anything raised to the power zero, one?

    [FONT="Arial"][SIZE="2"]HallsofIvy has given the best explanation one can possibly give for the question asked. The others seem fine (mostly), but they are not as clear or concise as the one given by HallsofIvy...

    Something interesting concerning parity

    [FONT="Arial"][SIZE="2"]An explanation such as this is alright for proving that an integer n is even if n=2k, for some integer k. Thus, we have to use our knowledge of even numbers to say that they end in an integer that is divisible by 2. A satisfactory explanation, no doubt, just not what I'm...

    Something interesting concerning parity

    [FONT="Arial"][SIZE="2"]Is there a proof or way of proving that all even numbers (taking into account the definition of an even number as n=2k) end in 0,2,4,6, or 8?

    Need help remembering a philosopher

    [FONT="Arial"][SIZE="2"]I remember reading a pretty fascinating story a few years ago, and I want to recommend it to someone -- but, for the life of me, I cannot remember the philosopher that authored the story. It was about a few men awaiting their death by firing squad.. I know its probably...

    Has anyone tried Gareth Jones' Elementary Number Theory? What's your review?

    [FONT="Arial"][SIZE="2"]I got the Vanden Eynden book yesterday and have started going through it.. It's a wonderful book. I'm very pleased and would recommend it to anyone looking to get into number theory. I get the feeling that once I finish this book I'll be more than aptly prepared for a...

    What Does i^i Really Mean in Complex Numbers?

    [FONT="Arial"][SIZE="2"] I like to think of imaginary numbers to be a convenient way to "extend the number-line" so to speak... If you look back in history to when we first conceived the "real" numbers, to the time when we formalized them into the set R and then to the point where imaginary...

    The Long and Hard Road to Becoming a Professor

    [FONT="Times New Roman"]It seems to me that tenure jobs will never completely disappear. Think of Academia as a funnel; new PhDs looking for work is the load and there's a lot more than can fit through the funnel. But, some still get through, these are the people that are replacing the tenure...

    Good northeastern astronomy astrophysics programs

    [FONT="Times New Roman"][SIZE="3"]I second this. I know a few students at Stony Brook who study Astronomy and they are extremely happy there. Also, I've heard only good things about NYU's physics and astronomy programs -- though I believe they only offer astronomy at the graduate level. Check...
