  • i don't get the ghost ants bit, can someone explain to me please...

    p.s. please use dumb dumb version..

  • I have a problem for you ! I can't figure this out ..

    A pill contains 400 mg. 8 hours after you eat it 80% of the pill is broken down (the pill is broken down exponential). If you can't have more than 1200 mg of pills in you how long do you need to wait in between every pill if you have a the same time in between all the time, over a long time.

  • You would expect the answer to be really complicated and when you see the answer you wish you would have figured it out for yourself...

  • Now

  • Cough up a new video no

  • Ok one second .. if the ants walk and turn around when they run into another and you said thats like if they "passed throug each other" but if they walked through each other then there would be a 0 > X < 1 point at which the ants would be inside each other .. now if we sat the ants in a repeating 0,1 order (0 facing left and 1 facing right) meaning that the ants in the middle couldnt move untill the ants on the sides got facing the right(as in not wrong) side.

  • Now hold on just a minute.

    The two ants at 0 and 100 centimeters are ALREADY at the ends and thus have walked off the stick by default to begin with, regardless of what way they were facing.

    In other words, it will take LESS than one minute at most.

    Unless you assume that an ant at the end is facing towards the stick and that somehow keeps her from falling off. And i say her, since male ants have wings and would fly away anyway.

  • @Amphibiot I believe they have to fall off the ends. And if the ant at 0 is facing right, it has to go all the way across.

  • At 1:18 you look like a rapper.

  • @08firthf *he's an author!''

  • @gC222SA I know, I'm just talking about the gestures.

  • I got it! I fucking got it! I never get these things right!

  • it really makes no difference, 30s to a minute is virtually what everybody said anyway, i was really expecting a different answer

  • It took me a few seconds to figure out a minute or less, but I thought there was an exact answer so I wracked my brain for like 3 whole minutes trying to figure it out before i watched the vid lol

  • Wouw this video deserves its 0 dislikes. :) i would have never thought about that :D

  • @Crashkiller62 DON`T WAKE THE TROLLS!!!!!!!!!

  • @nicholishere if they are not wake yet why should they be later by seeing that comment? :o

  • Got it right :) Though your explanation is a whole lot easier.

  • Of course, if we included one more ant (for 101), we would have avoided the ambiguity of their placement. But a fun puzzle none the less. Also interesting; I found that if an ant makes it more than halfway of the distance from its starting point and the end toward which it is travelling, it will have no more 'collisions'.

  • Wait..did you film the Anwser video right after the Question video?

  • @Contrabot Thats what I'm guessing XP It probably is just easier for him to film it all in one go

  • Mind = blown. As if there's a tiger gnawing on your face and you don't even notice it until someone tells you it's there.

  • collisions are tantamount to an exchange of labels in passing

  • I know the answer now!

  • I was right :D

  • "Mathematical ghost ants" would be the scariest horror movie ever.

  • @DiogeneshoKunikos especially for the kids in grade school which most likely REALLY dislike math XD

  • I honestly thought you were going to start juggling...

  • Comment removed

  • As soon as I saw you hold a ball I was hoping for a juggling act right at the end. I was disappointed, James! DISAPPOINTED!

  • Pls reply

  • @singingbanana if ants are spread like this. 0.5cm A 1cm A 1cm A ...................A 1 cm A 0.5 cm the 50th ant will be 49.5 cm away hence the shortest time is 29.7

  • But isn't the time for colliding shorter than the time it needs to actually get through each other? .. In the "walking through each other" part, there is extra length which is the diameter of the ball! .. Please tell me if I'm wrong! .. I enjoy your videos! :D

  • @EmiratiN3RD The ants are considered as infinitely small points without length, so there is no difference ;). Otherwise we would have been provided with that information.

  • @EmiratiN3RD No because he said they had no actual size and were just mathematical points

  • Amazing,i would never know.

    BTW I love your ending "If you are happy,thanks for watching"

    I am always happy when watching your videos! :)

  • @eXisentZ It's actually: "If you have been, thanks for watching."

  • @WiVaBo yeah i just heard it,anyway it's still a cool ending.

  • @eXisentZ But I like your version too. :)

  • Awesome puzzle, keep up the great work ^_^

  • what if you have an ant at the very far right, facing right. It will walk off instantly.

  • @Rockwarrior2004 Then theres 99 left :)

  • @Rockwarrior2004 The puzzle was for all of the ants.

  • @SaiyanKirby right forgot that was the original puzzle. Then i had gotten the answer right in the other video (Well aside from the fact that i did minutes vs seconds. but it still had sixty minutes vs 60 seconds and 30 minutes vs 30 seconds. So although my time was incorrect My answer was right.)

  • Man, I way WAY over-thinking this one lol

  • I feel insulted and enlightened at the same time!

    Insulted coz I just realized how simple it was.

    Enlightened coz I learnt something! HAZZA! :D

  • Lets say that all the ants are paired so that they're facing towards each other. After about a secound, they all collide switching directions and two ants fall off. The ants are once again all paired facing eachother but there are now two less ants with more space between them. When this is repeated until the the last two ants fall off, would it not have taken over a minute since the last two ants had to backtrack numerous times?

  • @sushicartman01 That is what I was thinking, the first ants would fall off near instantaneously, and the last ants would fall off sometime in the future (i never bothered to do the math, just a bit of a mental picture). It makes sense, though, that if they were to pass through one another it would take between 30s and 1m....

  • Twelfth!!

  • If the ants are spread out over the meter would there possibly be one starting off at the edge of the who if facing the correct direction would effectively jump off at 0 seconds making that the minimum time? So from any starting off position other than 50cm would have potentially less than 30 seconds to drop off depending on which way it was facing.

  • @maikeru2406 Just realised the 100 ants are spread all along the meter which would give 30 seconds minimum for them all to fall off the end.

  • To be honest, they won't be on the end, nor on 1cm intervals. So slightly less both times.

  • i knew about a minimal of 30 sec (29.7) but i still don't believe for a min to be max :D

    i need mathematical proof.

  • eighth!

  • cool

  • nice!

  • This seems so simple now, but I would never have been able to come up with the answer!

  • First!!!!

  • Yay I'm first to say first.

  • Rob eastaway - I have (or should I say my big brother has) 2 of his books!! Its pretty good.

  • I would never have guessed, but it makes so much sense!

  • @MortifiedThePenguin Played splinter cell: pandora tomorrow?

  • @Slowergrass432 What gave it away? jk jk
