  • By Grandswiss in The Movie Math Quiz - Part 5: 3 could also be "Infinity" (http://www.imdb.com/title/tt0217571/) as the sum approaches infinity. 8 could be "The Staircase" (http://www.imdb.com/title/tt0152588/) as it is the staircase function. read in context
  • By mfb in The Movie Math Quiz - Part 5: 8 could also be The Seventh Floor (it is the floor function). Why is 6 limitless? We don't know if the limit exists for that function. read in context

  • By dook in The Movie Math Quiz - Part 5: I don't know any of these movies except Gravity ._. read in context
  • By Dirk in The Movie Math Quiz - Part 5: SPOILERS! 1. Edge of Tomorrow 2. Gravity 3. Divergent 4. Identity Thief 5. Source Code 6. Limitless 7. The Gray 8. ?Step Up? 9. 21 and Over 10. Need for Speed (very clever, the absolute sign!) read in context
  • By HGoodwyn in The Movie Math Quiz - Part 5: I think I used the third one (the harmonic one) before this ;) read in context
  • By David Morgan-Mar in Difference between sine and cosine: I re-used this comic under Creative Commons at Lightning Made of Owls. Thanks for licensing! read in context
  • By bmonk in Difference between sine and cosine: just a sec. Let me think about this. read in context
  • By CC in Difference between sine and cosine: Do you think that guy can divide by sine? Cosecant! read in context
  • By Dean Gulberry in Difference between sine and cosine: Nerds read in context
  • By Hal in Three logicians walk into a bar: Just to clarify further, the barman assumes all want beer, but this is not necessarily the case. One or more may want spirits, plain water or whatever. Similarly, the logicians themselves do not know each others preference, so the joke quickly unravels in complexity. read in context
  • By Drachefly in Mathematical Modeling: That book does not represent an attempt to derive 1+1=2 as quickly as possible. There were many other higher priorities. read in context
  • By Joseph in Difference between sine and cosine: It's a sin to multiply tan by cos read in context
  • By MrWriteSF in Difference between sine and cosine: You need a break. Lie down on this cot. read in context
  • By Hal in Three logicians walk into a bar: To me this joke makes no sense. The statement "I don't Know" cannot infer whether Logicians 1 or 2 want a beer or not, it is merely a statement of fact that they do not know if everyone wants a beer. Hence Logician 3 cannot make the deduction that they all do. read in context
  • By imallett in Difference between sine and cosine: Why did I divide sin by tan? Just cos. read in context
  • By deyesed in MathWOW!: noo... the engineers won't have new tools in 100 years... read in context
  • By deyesed in Difference Between Numbers And People: He meant period as in periodicity. read in context
  • By Phi Onesixone in The Math Genie: Wisher: I wish that you would grant this wish in a weird, misanthropic manner. Genie: ERROR! *explodes* read in context
  • By Pirenz in The Riddler's Cube (Puzzle): You could have made it simpler by making it root 5 read in context
  • By Pirenz in Happy Tau Day: Well, what about radians. Yet if that still doesn't convince you, I understand. Why can't we use both anyways? read in context
  • By Pirenz in Happy Tau Day: The denominator is half! read in context
  • By Pirenz in Linear Algebra Problems: Haha! Good one! Imaginary numbers are real numbers multiplied by the imaginary unit! So bi where i=sqrt(-1) Complex numbers are in the form of a+bi and are the basis of the complex plane read in context
  • By Pirenz in Linear Algebra Problems: I like these comics! Keep it up Mike! read in context
  • By Pirenz in Linear Algebra Problems: I am sorry if I replied a bit late... read in context
  • By Pirenz in Linear Algebra Problems: You're welcome! Glad you understand it now! read in context
  • By Pirenz in The Perfect Score: No! The bar meant that the nines repeat forever! read in context
  • By Pirenz in Tired of adding C?: Very funny! read in context
  • By Pirenz in Why you deriving yourself: Good one, if he hangs with e^x he'll never be lonely since e^x is its own derivative. read in context
  • By Pirenz in Math Club Rules: Pi=3.141592653589793238462643383279502884197169399375105820974944592307816406286... e=2.718281828459045235360...... Phi=1.61803398874989484820458........ read in context
  • By Pirenz in Math Mnemonic 1: No! The line below explains the mnemonic! It is about calculus! read in context
  • By linotype in "Real" Job Interview - Part 4: http://i7.minus.com/ibs8O81MUcHWX4.png shows how to do this with 3 lines. read in context
  • By Uniden in "Real" Job Interview - Part 4: "... four connected straight lines" doesn't work either, because then you could just draw three horizontal lines and one vertical to connect them all. read in context
  • By pnr in "Real" Job Interview - Part 4: I believe the original problem statement is stated wrongly here. Even on a plane, one only needs to draw three horizontal lines to connect all 9 dots. To pose the usual challenge, the question must state "... four connected straight lines". read in context
  • By Anonymous in "Real" Job Interview - Part 4: This is the best comic I've read so far! read in context
  • By Spiked Math in "Real" Job Interview - Part 4: Ignore the paper size, I meant to make it larger before posting. :-( read in context
  • By Loretta in Linear Algebra Problems: WebMD on the doctor's screen? LOL! Thanks @Pirnez for your explanation. I had to pretend I got the joke until I read your post! :) read in context
  • By Eli in A friendly game: These comments talking about the left guy needing one more T to win don't make sense anymore. In the current version, the left guy is H. Did the original version of the comic have the heads/tails sides reversed? read in context
  • By Leon Luna in Three logicians walk into a bar: Not sure, the question is does everyone wants a beer? the first logician answer i dont know (the meaning of this is that this person doesnt know if the others want a beer, same with the se second person , the last person assume that the others want a beer and he answer yes but this is not true we dont know if the first or seconde logician want a beer , for me it doesnt have sense read in context
  • By Pirenz in Tired of adding C?: Lol Let me do one Int(10x)=5x^2-tan(monkey)+42, where monkey is any constant read in context
  • By Jayuan Yao in Three logicians walk into a bar: ohhhhhhhhhhhhhh I see read in context
  • By Meg in Three logicians walk into a bar: Funnily enough, they all struck me as looking female, and that was before I even read your comment. I think perhaps because they all look like they are wearing dresses (the triangular garment registers as a dress to me, and their hair and faces don't register as particularly male, so it defaults to female in my mind). Strange how differently our biases play out, isn't it? read in context
  • By Pirenz in Number Theory Exam: Cool! So therefore you proved that x^3-x^2+3x=16 has no integer roots by using method of contradiction! Q.E.D. read in context
