Why is this not correct (suppose n->infinity): nth root (n!) = nth root (n(n-1)(n-2)(n-3)...(n-n)!) = nth root (n) * nth root (n-1) * nth root (n-2) * ... * nth root ((n-n)!) = 1 * 1 * 1 * 1 * ... * 1 = 1 => nth root (n!) = 1 It is clear that nth root (n) = 1 as n-> infinity and that n! = n(n-1)! Yet jewframalpha gives me infinite as the limit and not 1

Totally Useless College Majors

So I always enjoy a good college major pissing contest. We all know STEM is god-tier if we are on /sci/....lets name some really horrible majors itt and explain why they suck I'll go first: ______ Studies This includes gender, racial, and general. It sucks because you spend four years doing something I could've learned in a summer with a library card

Imagine this: You can stop time. Like in movies and such, objects won't move, or notice you. You do however notice everything, and are still capable of using your body fully. Now would you be able to walk through air?

Is studying geological engineering economically viable? Have any stories of somebody who took it in uni?

Hey /sci/ I got a question for you. Im reading a textbook on digital design and Ive ran into a strange boolean equation that has the same output for the function and the complement. The function is W•X + Y•Z and its inverse would be W`+ X` • Y` + Z`. For the input WXYZ = 1110 they both give 1. Whats going on here?

Hello. I am wondering if anyone here would be up for a debate on empirisism and post rationalization. I know this is alot philosophical but also very important for science in general and without scientists this debate is not possible. I myself finished study in law and plan on starting philosophy now. I think (and also learned) that with scientists you have the highest chance of getting a good debate, because they are more likely to be open minded (atleast the brilliant ones) and mosten calm and resistent to rage (most i've met). Hope this hasn't changed. Also would be interesting if you would include your subject of study (hasnt to be on college, private studies work aswell)

riddle

7 more posts in this thread. [Missing image file: cards.jpg]
Q: You stand blindfolded in front of a table. you are told that there are 32 cards with the number up and an unknown amount of cards (so it's not sure it's 52) with the number down. Is there a possibility that you can divide the cards in two groups so that both groups have the same amount of cards with the number upwards. Note: there is a chance that the answer is no, but that would be really stupid. It's a question from my gf school for 15 to 16 year olds

Ever wondered what it's like to actually study physics?

I need a 820 ohm resistor and a 470 ohm resistor. I currently have 10 100ohm resistors and 2 1k resistors. Here is the circuit I am wanting to complete. Would it be ok to substitute the 820 ohm with 8x100ohm in series. And substitute the 470ohm resistor with 2 1k resistors in parallel? This is to write/read data to a PS2 memory card. I have completed circuits here and there in the past but have never substituted different value resistors. Thanks in advance!

Halp, /sci/, I'm in despair and need the help of Anonses. In 6 hours I have to asses biology project, in which I have to check whether music affects one's heart beat rate. All u would have to do is to measure your pulse while sitting, and then listen to four songs of different genres (with measuring pulse after each song). Would be awesome if you verified whether you're manon or femanon. Songs: 1) http://www.youtube.com/watch?v=8Qx2lMaMsl8 2) http://www.youtube.com/watch?v=FHp2KgyQUFk 3) http://www.youtube.com/watch?v=ab9176Srb5Y 4) http://www.youtube.com/watch?v=St6ZzLMMVe4 It won't even take 20 minutes of yours, and you will make a /sci/ bro extremely happy (and let him pass this year...) Awaiting your answer, Anon P.S. I already posted this on /b/ (which I think was not the best move) but I thought that /sci/ is more suitable for this
