Mismag822 - The Card Trick Teacher I swear you have existed on TH-cam forever Mismag. I used to watch you 4+ years ago. Great to see you're still going. Hello again everybody ;)
OMG you just taught me a new way of counting a binary number... :D For example, let's take 1100101. I used to sum right-to-left 1+4+32+64=101, but I had to remember first the position of each power of 2. Now, I can read left to right, beginning with 1 and doubling or doubling plus one - depending on whether 0 or 1 appears next. In this case, 1, 3, 6, 12, 25, 50, 101 :D
QuasarRiceMints I am ashamed that I didn't get that until I read your comment twice, especially since I convert numbers to binary with the exact reverse of this method...
This would be a great way of giving an immediate and fun application for people learning binary as such it would be a great tool for teachers to employ.
Jack Elliott That's exactly what I thought! I taught my Year 7 Maths students about binary last term and I can see how this would be a fun way to show the applications of binary to every day life.
Wow, that was the best video in a long time here; possible the best ever. The maths, the card skills, the writing sideways and upside down. Perfection. Good job, Jason.
I love they way he writes upside down to make it easier to show the camera. I did that in front of a customer & they flipped out, "how did you do that?" what, write upside down? easy :)
Best bit was at 4:48. Brady's reaction is all of us. "I still don't see how you did that!" Overall a very impressive and truly tricky maths card trick.
Not impressive at all. He did not move "the card" to the top of the deck, he cut the deck so that "the card" was on top of the bottom half of the deck, and then cups his hand over the deck using his fingers to grab the bottom half of the deck and lift that bottom half into the air while the top half of the deck remains in his hand, then he "sprinkles" the bottom half of the deck onto the top half. Sleight of hand.
@@rotagbhd first of all, it being sleight of hand doesn't make it not impressive. Secondly, that's not all there is to the trick, that's just the first step.
That last part with the binary. KABOOOOM! That was my brain being impressed, and then realising... yes, that is how binary digits relate to n, 2n and whatnot. Mathemagical!
Ooh dat sneaky Pass! Also, that is called a Faro shuffle, and it is a kind of shuffle used to manipulate the cards. With the pass, the Faro can seem magical, as demonstrated.
I would really like to see him explain the technique of the perfect shuffle, or at least show more closeups of his hand positions and how to make the shuffle work so I can mimic it.
Getting the cards to weave together perfectly is surprisingly easy if you have a nice crisp deck of cards, the harder bit is consistently cutting the deck into equal segments.
What's the deal here?... he said it would take four shuffles, he actually did four shuffles, but he should have had to do five shuffles? My best guess is that he initially moved the ace of clubs to the second position instead of the first.
I'm astonished that this video has not drawn more comment from fellow card magicians; We must be a much smaller group than I thought! The "perfect" shuffle that he so expertly demonstrates, is in fact a Faro shuffle. The late, great Ed Marlo was the master of the Faro shuffle, and published a rare but excellent booklet on how to perform and use it. Let me offer a few tip to those aspiring to master the full-deck Faro shuffle. 1. Use a new, 52 card deck of Bicycle brand playing cards 2. Work with clean hands and don't bend the cards 3. Find a Faro Shuffle tutorial on youtube, and look for Ed Marlo's booklet. 4. Carry those cards with you everywhere, and practice every chance you get.
Very interesting to see that shuffling cards like that can be made. But, although it's not the topic of that video, each time I saw someone wearing a ring on his thumb... I keep remembering the CPR course I got years ago which warn us to never wear a ring on our thumb. Because if there is one finger you don't want to lose, is your thumb! And having a ring increase the risk on that finger to lose it...
One additional point since it isn't mentioned anywhere: At the beginning of the video, the guy said he could get to any position in 5 shuffles but 5 digits of binary only count to 31 which is not enough to get through a pack of 52 cards. For those who want to do the trick in 5 shuffles: So if Brady picked a number like 45, then the guy would have put the card in the 7th position from the top, i.e. 6 cards above it and then started counting cards from the bottom of the pack instead of the top :) (This example would take 3 shuffles)
If every race in the galaxy used binary, then yeah. I can probably get used to base 12, but i doubt Gorglax would feel safe if i told him the price in base 12. He'd probably have to google it.
LOL... I agree that base 12 should be the default way of counting... but math in general (not the symbols used) are the universal language OF the universe. edit: typo
The math is quite simple, handling the cards like that is pretty impressive. I'd like to see that with a deck i've been playing for twenty years now ^^
There are still a few unexplained things happenning : - he only did 4 shuffles : he must have put the card on the second position, not the first one. - how is he splitting the deck exactly in half to do perfect shuffles ?! It only matters if the number chosen is large, but whatever, he manage to do it every time !
Splitting the deck exactly in half requires a fair bit of practice, but is very possible for someone to learn, especially for anyone interested in doing faro shuffles.
Sylvain Janet You don't have to split the deck into halves exactly cos the bottom cards are essentially useless and there was one shuffle where there were 2 or 3 cards at the bottom.You just need to be precise on what's above the given number.
So if you have a deck with N cards. Each time you shuffle, you take k cards on the top of the deck and rearrange them in the deck with N-k cards. so that they have q-1 cards between two consecutive cards. There are q-1 ways to shuffle the deck like that, depends on the position of the first card of the deck after shuffling (r=0,1,...,q-1). Do you use the q-base numbers ?
That's actually a pretty cool way of translating binary into decimal. Instead of doing the powers of 2 thing and adding all those with a 1, you just start with 0 and then read the number doing 2x+1 for every 1 you encounter and 2x for every 0... That's alot faster in my opinion :)
I am a magician and a few years ago i learnt an effect by lewis le val now i believe even he doest know how it works and while i was still in school i asked my maths teacher and he had no idea either both knew it was some form of mathematical principal and i thought these clips would give me the answer but instead they have made me more confused ... so now I'm here on numberphile asking if anyone would take a look at a performance if i filmed it and see if it is maths or just luck
What is your strategy if they choose a number higher than 33? I can't think of a way to get around the 6 shuffles or things like cuts that a layman would still count as a shuffle. I guess you could secretly do a cut at the middle, and subtract 26.
In my first digital engineering course (taken back in the mid 70s) I was taught the binary-to-decimal conversion algorithm covered here under the name "double dabble." See the Historical section Wikipedia's entry for double dabble.
Vineet Patel I was wondering about this too, but I've figured it out! During his explanation, he says he puts the chosen card on top, but he really puts one more card on top of it, making the first 1 shuffle unnecessary. (You can see this barely if you slow the video down to 0.25x and look really closely during his performance of the trick.)
Collin Deel This makes sense when you consider the trick represented in binary, every number they could have chosen would have to start with a 1, unless they chosen the 0th position, so using slight of hand to put the card in the second spot would (almost) always work
He just figured out the pattern before the guy mentioned it ;) can feel awesome when things click in your head. Great trick btw but felt a little cheated when he told that he moved the card before the shuffle.
Holy shit - when I saw how he shuffled I wanted to try it out myself, so I got my deck of cards and took it out of the pack when I noticed 1 card had stayed behind, and I shit you not - it was ace of clovers
Getting the card on top is nothing in comparison to making continuous perfect shuffles. I mean when the put the card in, hold the position of the card from behind with your pinky and then cut the deck three times so that you end with their card on top. But perfect shuffles do take time
Something's gone wrong, here. At 1:50, he claims he's showing us the results of a perfect shuffle. But look at the row of card to the left: it includes both the bottom and the top card of the deck. So, either the shuffle isn't perfect and there are two cards adjacent in the right row, or the deck has an odd number of cards in it!
10101 is five shuffles, but he says he did it in four. 0:47 When doing this trick, do you naturally do the first perfect shuffle before asking anything?
Getting the card to the top is the easiest part. All he does is flips the bottom half of the cards over to the top immediately before sprinkling. He grabs the bottom half of the cards with his right hand so it's tougher to see.
0:19 the only non-mathematical part of the trick is exactly the moment where the words "using maths alone" are spoken. i love this timing.
Easy to tell when a magician is lying: his lips are moving.
This is not easy, but it is an amazing trick!
Oh, wow! I didn't know you watched Numberphile!
Mismag822 - The Card Trick Teacher I swear you have existed on TH-cam forever Mismag. I used to watch you 4+ years ago. Great to see you're still going.
Hello again everybody ;)
Dang mismag since when do you watch numberphile?

Wow, that's right. This is indeed a great revelation.
Now that is nice... I shall certainly be using this method from now on
Excellent insight. I just got smarter thanks 2 u.
QuasarRiceMints I am ashamed that I didn't get that until I read your comment twice, especially since I convert numbers to binary with the exact reverse of this method...
***** Nothing to be ashamed of ;) Everyone has their moments of less inspiration :D
Awesome use of binary
This would be a great way of giving an immediate and fun application for people learning binary as such it would be a great tool for teachers to employ.
Jack Elliott That's exactly what I thought! I taught my Year 7 Maths students about binary last term and I can see how this would be a fun way to show the applications of binary to every day life.
This is a great way to introduce binary in class, now I just have to learn how to do perfect shuffles...
Wow, that was the best video in a long time here; possible the best ever.
The maths, the card skills, the writing sideways and upside down.
Perfection. Good job, Jason.
I love they way he writes upside down to make it easier to show the camera. I did that in front of a customer & they flipped out, "how did you do that?" what, write upside down? easy :)
Ohhh that's why he wrote like that... I try to write upside down in for my clients all the time... just looks a mess. I gotta try this!

Sleight of hand.
@@rotagbhd first of all, it being sleight of hand doesn't make it not impressive. Secondly, that's not all there is to the trick, that's just the first step.
The most impressive thing here is how he writes upside down!
With his left hand!
And sideways too.
Yeah but look at the way he holds the pen
@@FerousFolly yeah I used to write like that and got beaten😄
That last part with the binary.
KABOOOOM!
That was my brain being impressed, and then realising... yes, that is how binary digits relate to n, 2n and whatnot.
Mathemagical!
Binary is 2^n...
Yes, but take n = 101010 (42)
2n = 1010100 (84)
There's a clear relationship. But yes, it is based on 2^n
Forget the card trick, I want to learn how to write upside down like that. Now that's talent.
Facts!
Harry Kane has been doing cats tricks too much, that’s why he’s forgotten how to play.
If I could do perfect shuffles, this would be my favourite card trick in existence.
learn it on yt it called the farro shuffle
That binary part just made it one extra level of more awesome and one extra level more of convenience because that's a really easy shortcut to use.
An alternate universe where Harry Kane studied maths instead of playing football
This is the awesomest trick I've ever seen.
Ooh dat sneaky Pass!
Also, that is called a Faro shuffle, and it is a kind of shuffle used to manipulate the cards. With the pass, the Faro can seem magical, as demonstrated.
I would really like to see him explain the technique of the perfect shuffle, or at least show more closeups of his hand positions and how to make the shuffle work so I can mimic it.
didn't know Harry Kane was also a magician
Is his hair perfectly ruffled, too?.
I could watch these videos forever, I seriously could..
marlo tilt beginning works quite well, second position allows you to skip first faro there
Nice pass and beautiful shuffles.
That was amazing! Mooooom!!!!! Where are my cards!?!

What's the deal here?... he said it would take four shuffles, he actually did four shuffles, but he should have had to do five shuffles?
My best guess is that he initially moved the ace of clubs to the second position instead of the first.
The real magic trick was how he wrote that 22 with that orientation from his holding and position.
Yes! I stopped the video and tried to write like that before I even saw the trick!
That perfect shuffle alone is amazing
I'm astonished that this video has not drawn more comment from fellow card magicians; We must be a much smaller group than I thought! The "perfect" shuffle that he so expertly demonstrates, is in fact a Faro shuffle. The late, great Ed Marlo was the master of the Faro shuffle, and published a rare but excellent booklet on how to perform and use it.

And having a ring increase the risk on that finger to lose it...
I love this video. There is an amazing amount of trickery and illusion all in one video!
How does he split the deck directly in half?
Practice.
Witchcraft
It does not need to be split exactly halfway in this example. as long as he has at least 21 cards in each group, the trick will still work.
just look at his sleight of hand, he knows his cards :)
Mike Ralph
Not if Brady picked a number higher than 26.
His skills are such a high level of sorcery, I could never do that effectively!
One additional point since it isn't mentioned anywhere:
At the beginning of the video, the guy said he could get to any position in 5 shuffles but 5 digits of binary only count to 31 which is not enough to get through a pack of 52 cards. For those who want to do the trick in 5 shuffles:

Great video. I use perfect faro shuffles I’m my card trick routines all the time.
He says he can do it in 4 shuffles, but then the math after shows he needs 5 shuffles. I don't understand the discrepancy.
Sleight of hand was great but that binary part blew my mind.
Most impressive this in this video? Jason writing upside-down left handed!
that is some funky grip on the sharpie....
This card series was great
Math is the universal language. I love it !
If every race in the galaxy used binary, then yeah. I can probably get used to base 12, but i doubt Gorglax would feel safe if i told him the price in base 12. He'd probably have to google it.
LOL... I agree that base 12 should be the default way of counting... but math in general (not the symbols used) are the universal language OF the universe.
edit: typo
More by this guy please!
You could also do this trick with a smaller number of cards so you can do an easier perfect shuffle more quickly
Wow! He writes in a magical way!
The math is quite simple, handling the cards like that is pretty impressive.
I'd like to see that with a deck i've been playing for twenty years now ^^
what a beast. awesome video
Oh my God!!!!!! This is beautiful!!!!!!! I absolutely love it!!!!!! I love math and I love magic!!!!! This is insane!!!!!!
Nonchalantly writing upside down better than i do right side up is the real magic here!
Really liked this video !
Loving this card/math videos
That suffling part was neat but easy to follow. But the binary part? mind.blown. I didn't see that coming.
I saw Rob Eastway do the same trick at a Science showoff gig, except he had a back up plan if it all went wrong. Still an amazing trick
That's a real clever trick.
There are still a few unexplained things happenning :
- he only did 4 shuffles : he must have put the card on the second position, not the first one.
- how is he splitting the deck exactly in half to do perfect shuffles ?! It only matters if the number chosen is large, but whatever, he manage to do it every time !
It's 100% about practice. He's great though :O

" It only matters if the number chosen is large, but whatever, he manage to do it every time !"
it doesn't seem to need to be perfectly in half, unless the viewer chooses a large number.
This is really cool!
I suddenly have an urge to go get a deck of cards.
I'm currently learning the Faro shuffle and happen to be familiar with binary. Thanks you so much!
Right when I realized it was in binary, my mind was blown. How does that work!?
that perfect Shuffle Looks insane :o
I love how blown away Brady was by the sleight of hand. My cynical magician self was just like "Obvious pass is obvious."
You should do a video about strategies in solving the Countdown math problems.
So if you have a deck with N cards. Each time you shuffle, you take k cards on the top of the deck and rearrange them in the deck with N-k cards. so that they have q-1 cards between two consecutive cards. There are q-1 ways to shuffle the deck like that, depends on the position of the first card of the deck after shuffling (r=0,1,...,q-1). Do you use the q-base numbers ?
Now that makes math fun!

This guy is a little better at doing perfect shuffles than Federico Ardila in the last video :P
This guy writes upside down like a beast
the fact he was able to write everything upside down is almost more impressive than the trick.
Amazing pen holding skills!
I am a magician and a few years ago i learnt an effect by lewis le val now i believe even he doest know how it works and while i was still in school i asked my maths teacher and he had no idea either both knew it was some form of mathematical principal and i thought these clips would give me the answer but instead they have made me more confused ... so now I'm here on numberphile asking if anyone would take a look at a performance if i filmed it and see if it is maths or just luck
This is like asking Hendrix how he makes it look so easy.
Factorials is a mathematical method to solve combinations
What is your strategy if they choose a number higher than 33? I can't think of a way to get around the 6 shuffles or things like cuts that a layman would still count as a shuffle. I guess you could secretly do a cut at the middle, and subtract 26.
Fun fact. If you do the same perfect shuffle 8 times in a row, the deck will return to the exact same order it was in before you started :)
Which they would have done it with the top card showing face up! Absolutely amazing.
Loved it!
"mathemagics" I will never forget that line
There were a couple of chapters in the manga "liar game" that used this trick
Yeah this reminds me of the poker chapters.
Lola Ritter yup, that's where it's from. The game that took place in the library.
Yeay, i fugured it out bevore The explenation :D cool trick and i like how you move your hands :p its smooth :)
In my first digital engineering course (taken back in the mid 70s) I was taught the binary-to-decimal conversion algorithm covered here under the name "double dabble." See the Historical section Wikipedia's entry for double dabble.
Great, make more math-card tricks, it is very interesting!)
The craziest thing about this video is how that dude held his pen
Dafuq I was really stunned at the end when he showed the "easy" way of doing it :D
At 0.47 he says "4shuffles". But the answer is 5 shuffles!
Vineet Patel I was wondering about this too, but I've figured it out! During his explanation, he says he puts the chosen card on top, but he really puts one more card on top of it, making the first 1 shuffle unnecessary.

At first i was really impressed, but then the binary part really blew me away :O Mathematics is incredible.
yeah, how the f**k does binary numbers fit perfectly on what he wants to do here... amazing... exactly the part that all those 1s and 0s equal 21
The sleight of hand only works if you put it in yourself, though.
lol wtf when my video was at 7:17 i googled "10101 in binary" and at 7:42 he says that it was binary for 21... 0.o
He just figured out the pattern before the guy mentioned it ;) can feel awesome when things click in your head. Great trick btw but felt a little cheated when he told that he moved the card before the shuffle.
ColaboyXL What's the point of this comment?
You needed to google that? O.o
curtcolt if you don't get the point of my comment then how can your comment have a point? Kappa
Hendrik W yes... I'm not a computer programmer...
Holy shit - when I saw how he shuffled I wanted to try it out myself, so I got my deck of cards and took it out of the pack when I noticed 1 card had stayed behind, and I shit you not - it was ace of clovers

10101 is five shuffles, but he says he did it in four. 0:47
When doing this trick, do you naturally do the first perfect shuffle before asking anything?
Derek Gooding why hasn’t anybody answered this??
What if someone picks a large number like 42? Do you put the card on the bottom and work your way up?
This is the mist exited i've been for a magic trick since i was 10.
Such Faro,
Very nice.
Getting the card to the top is the easiest part. All he does is flips the bottom half of the cards over to the top immediately before sprinkling. He grabs the bottom half of the cards with his right hand so it's tougher to see.
how he holds the pen :o
with left hand.
That was so damn cool. Wow.
He writes better upside down than I do normally.
"That's a perfect shuffle, that's good enough for me" lols
This trick does not require someone to do a perfect shuffle, it only requires us to know how to do a partially perfect shuffle
he's a wizard.
