Exponential growth


I don’t think there was a puzzle like that in the actual thing. I realized that the flash wasn’t really that funny when I was halfway done making it, but I had come too far to just not finish it. So now, you get to watch a flash about unnecessary mathematical calculations. But anyway, there was a similar question on today’s math quiz, and I decided to use math instead of logic (because you know… it’s a math class), which ended up being a bad idea, because it wasted like five minutes. What’s funny is that the question on the quiz was about tribbles being brought into the school and multiplying until they filled the maximum capacity of the school in an hour and two minutes.

After the quiz, the teacher started talking to us about how there was this one episode of Star Trek where the Starship Enterprise went to some Bahamas-like planet for rest and relaxation, but it turns out that the Klingons were also going to the same planet, and they had tribbles with them or something like that. He started explaining a bunch of Star Trek related things to us over the course of maybe two or three minutes, and it was kinda funny because nobody knew what he was talking about.

Anyway, what was I going to say? Oh yeah. What’s worse than the fact that Long-haired Character did all that unnecessary math is the fact that I actually did the math myself for the purposes of making this flash as mathematically accurate as it can possibly be. I don’t really like how long these sentences are. Also, now that I think about it, I can’t believe I actually used logarithms in a real-life situation (yes, making a flash qualifies as a real-life situation) where I didn’t have to.

  • I thought it was funny. Then again, maybe it’s because I’ve done things like that before. >_

  • SCIENCE!

    Lets see logic take on these tricky questions!

  • Reminds me of a D&D campain puzzle i once threw at my pc’s… One particular PC whould solve all the puzzles so I did this riddle that went somting like

    there is a 15in by 15in by 15in box with a spear in side whos radius is in there are 2 buckets one half way full leater bucket and one half leader bucket that is empty. you can fill the buckets when ever you want with a liquid. you have to completly submerge the ball with out spilling any liquid or there being any over flow.

    So genous siyor can not figure this out after some long time of calculation and me reassuring that it is possible the random freshman person decided to take out the ball and put it into the bucket.

  • @ That Guy

    THAT PERSION JUST USED A GOTO STATMENT!!! AHHHHHHH!!!!

  • This puzzle is actually more applicable than most of the puzzles that Layton has to offer, which was a minor source of irritant when I was playing it.

    I think once in a while ago, I did indeed encounter a variant, if not the same, puzzle involving the tribbles. If I remember correctly, though, the one I saw related to integrals and the exponential growth formula. The math teacher who presented it also had a thing for Star Trek; our final had the number 47 in all of the questions, which apparently is a reoccurring number in Star Trek episodes (not a Star Trek fan myself, wouldn’t know). Learn something everyday, yeah? Even if it’s useless trivia.

  • why’d you use log????

  • Ahahah
    Well thats funny to me.

    The whole “it doubles every 5 mins” thing gave it away when I read it.
    It was half full at 55 mins and double that in 5 mins and you get full at 60 mins.
    I was laughing the whole time i was scrolling through the math equations Long-haired character was doing.
    Talk about unnecessary XD

  • My brain hurts.

  • this problem is too problematic for me

  • Who would be stupid enough to bring Tribbles into a school?
    I mean, they’re cute and all, but I personally would not wish to die a death of furry suffocation.

    Also, questions like that always get me too.
    Wasting all that time on math only to find out I just had to think for two seconds.
    ANGER.

  • luls

    common sense ftw

  • My Math teachers often gave fun trick questions. I know for April fools day, one of my math teachers gave a quiz that, in bold letters, said READ ALL PROBLEMS AND INSTRUCTIONS BEFORE BEGINNING. It was then followed by 15-20 fairly difficult, but within our abilities, math problems. At the end, it said “Put your name on the paper, turn it over and wait for me to collect the papers. You do not have to answer any of the above problems”.

    That may or may not have been the same teacher who had a student fall asleep in 4th period, so he just let him sleep. The kid didn’t wake up until the beginning of 6th period. Sucker.

  • Hooray! Professor Layton ftw!!

    also you just spoiled one of the puzzles >.> oh well.

    Hooray!

  • Does this mean Reimu is a math genius? She uses logic, after all.

  • Ah! i got it

  • Ahahahaha, yes the ever classic “Are you a Pure Mathematician or not?” question.

    “Our Maths is too beautiful for this world” – the Pure Mathematician doesn’t care about The World and solves a problem just because it’s a beautiful mental exercise. Logic is for practical people with Maths being a tool. Cutting edge Pure Mathematicians don’t give a damn about logic and will tinker around with completely unphysical and impossible things because it’s fun to mess around with…… well they’re no longer numbers anymore.

    Maths is a Means, it need not be the End unless you really really enjoy it~~

  • Or perhaps it’s more accurate to say this is a “Thinking vs Reacting” question. Especially under pressure (e.g. exams), you’re less prone to Thinking and you’ll be trying to grasp at past experiences to React – because it’s seemingly faster and reliable.

  • Well, even if you DO use math instead of logic, there is faster way to solve it.
    20 = Ao(2)^(60/5); Ao = 20/(2^(60/5))
    10 = Ao(2)^(t/5); Ao = 10/(2^(t/5))
    20/(2^(60/5)) = 10/(2^(t/5))
    2/(2^(60/5)) = 1/(2^(t/5))
    cross multiply
    2*2^(t/5)=2^12
    2^(t/5)=2^11
    t/5 = 11
    t = 55
    Of course, using logic is still faster than this.

  • Haha, interesting

  • @Friz: I don’t actually know if this is a puzzle in Prof Layton, I just made it up and put a DS in the flash because I needed a reason for Long-haired Character to solve the problem.

    @Nipa-☆: Yeah, there’s probably a lot of other ways to do it mathematically. I just chose a longer way because it further shows that she’s using unnecessary math. Or it could just be because we’re learning about logs and I felt like putting that in somewhere. Maybe both.

    I think making this flash really helped my understanding of the change-of-base formula, because now I can use it without trying too hard to remember what goes on top and what goes on the bottom. Hooray!

  • THIS REMINDS ME OF A PUZZLE

  • After you do math for a long enough period of time things like that start to be your answer to everything.

  • My brain hurts…

  • lol, those calculations are awesome. XD

  • XD

    I’m just amused by the “density of math” thing, myself.

  • I HAFF TVELVE METCHSTEEK

    I mean… I thought the answer was 59, but then I saw it doubles every FIVE minutes, so yeah that’s right. :[

    Also, brain exploded.
    Thanks.
