HTML-код
- Опубликовано: 9 июн 2024
- Did you know there are more ways to shuffle a deck of cards than there are atoms in the universe? Seems crazy, but it's true. Today The Why Files covers amazing math facts (and tricks) that will convince your friends you have super powers.
Math is everywhere. It’s the source code of the universe. Most of the time math makes perfect sense. But sometimes math just gets…. weird.
These math facts that will blow your mind. You'll learn about the Birthday Paradox, secrets of Pi, how to create numeric palindromes with your mind, and our favorite: the mysteries of the number nine.
How many people do you need to get together before you find two that have the same birthday? Here's a hint: not that many.
How quickly can you calculate 1,111,111 squared? We'll show you how to solve this in 5 seconds. You won't believe the answer when you see it.
And nines? Nines have a whole thing going on. Multiplying by nines = magic. Squaring nines = pure sorcery!

New favourite channel alert ❤️❤️ please keep making more! Love from lockdown in London 🙌🙌
You're so kind for saying that Sofia! New episode being built right now. --AJ
this channel would be bigger with more fish 🐟
Yeah you're right.
Got a new favourite channel here!
How much I loved this channel?
Easy 1 trillion googol fathomable math, oh boy I'm feeling kind of black hole in my brain😂😂😂😂
I’ll bet you had really good parents
Horse racing fans understand your factorial presentation in their sleep
Seeing how different the show is now is wild, but it just shows the amount of work AJ has put in. Great stuff man.
Right? And whoever made the change to the Hecklefish voice we have today should be promoted. That single change brought millions of subs. I’m sure it was AJ but I just know his wife and the other two we see on the livestreams put in lots of ideas, too (so I didn’t wanna automatically assume it’s only AJ who made these changes).
You know I actually see a lot of what the show is now in this video. If this really is the first episode, then he started off real strong!
I was glad to see the change in Hecklefish.
@@PneumaNoosewhat was the early channel like? I am more recent and went to oldest and this was the oldest video so assuming a lot got taken away. I’m always just intrigued to see ppls growth as it’s inspiring to see everyone starts somehwere. Or was this really the first?
@@ExplorewithSarahlouise just compare the voice to newest to oldest. The new Hecklefish voice is WAY better :)
Math would have gone very differently for me if my teachers had explained these concepts as simply as you did.
I absolutely HATED math but I totally agree with you. I have learned way more math as an adult just from videos like this because it's the way math is presented. Some of the most eye opening math lessons have actually come from TikTok.
Wish my maths teacher was this interesting all those years ago!
I took trig and pre-cal in the 8th grade (geek class), then failed algebra twice in high school because I literally could not stay awake in class. Counselor put me in this crazy teacher's class and aced it.
Yep, we were taught to chant maths formula without having a clue how to use them.
Totally agree!!!!
It’s fun to come back and see how much the production level has increased over the years. Keep it up
I cant believe how quickly it happened, either. They really got it down pat QUICK and found their style
It's interesting to see how Hecklefish's mouth has gotten smaller too!
I decided this morning to make a backwards que of all the WF oldest to new. He has come a long way in 2 short yrs for sure!
@@HazyJ28that’s because their controlled opposition. Tbey might have not started out that way. It’s all about who throws a lot of money at them.
@chrisdaniels- controlled by WHO?
With this video, I have successfully watched every single Why Files.
Me too!
I hated math in school. But as an adult, I find myself marveling over it. When explained correctly.
Same.
Unfortunately you had poor teachers.
Yeah school is great at teaching you how to hate learning 😆. Good thing we have the internet!
Same here. I took up electronics engineering and graduated abhorring math. However, the older I get the more I came to marvel at, and respect math. Now, I tutor my teenage daughter on math.
Teachers are drastically underappreciated and under paid to our own detriment. We are whirling towards Idiocracy
Is it just me, or he seems so much more interested and passionate about this, than any of his other newer videos? He really enjoys math and breaking it down for us.
What a terrific teacher.
Yeah you are right
It just seems less refined and produced. I think he is still pretty chill and has a great sense of humor. Maybe these were when it was a hobby or a passion and now maybe it has become his full time job!? Idk I like him in all the videos.
I was just thinking the same thing !
He’s just excited to do a video that isn’t about a tin foil hat conspiracy…
Math is ridiculously interesting. Most math teachers mention how it's found all throughout our world, but they don't address any of it in a way to show how cool it is. The patterns are fascinating af.
After watching all your recent videos with big stories. This this is just as awesome. The 52 deck shuffle still is so incomprehensible
It doesn't seem possible does it?
Seeing how hecklefish has evolved over ~200 episodes is really cool! His voice sounds so much better in new eps too. :) really great seeing the show evolve

I took a class on statistics years ago in college and it ended up being one of the most interesting classes I have ever taken. The professor not only knew the subject but knew how to present it! Fascinating stuff!
You could have saved all that money by just waiting and then watching this video.
@@ranchdressing1037 It only cost about $65 for the course... this was back in the stone age!! lol (70's)
Damn! What are the odds of that?
A good teacher is worth their weight in gold.
I have made it from the most recent video through to this very first upload. You are consistent, fun, and objective. Keep it up AJ, Hecklefish, and crew. Seriously love it!
i just made it to the end as well.....now what do we do?
@@perry92964 we wait... I CANT WAIT
After binge watching his content, noticed he sits down in the beginning in most, but not all of his videos. I’m currently working on my own conspiracy theory on why…😂
haha im literally doing the same thing. I couldnt understand why he kept saying people hate Hecklefish, but as I went back in time I could see why lol. I was also noticing the background was showing other videos of his popping up. Makes me want to watch in order to see if they were showing what videos were coming up next, or are they videos that just happened
@@johnsummers101 hate heckle fish cant remember what episode but the lawyer jokes were pouring out and it was funny
love watching old videos of why files and seeing how far you have come.
Hecklefish not moving is crazy lol
I'm glad even this video got over 1 million views. People could watch AJ talk about anything!
You’re gonna go huge man, very professional video. Very intelligent and very interesting to watch! 👏
Thanks so much, Nathan! I hope you stick around with us!
It would seem you were right.

Except that there are multiple math errors, a sheet of paper being 10mm thick, the Earth being 45,000km all around, somebody in the back is obviously smart but the guy in view can't even convert miles to km properly, or inches to mm. I'd blame the U.S. education system, but thinking that a sheet of paper is thicker than a 9mm bullet???
ive seen this dude on tv before, hes got the personality down from his syndicated days
Let's see...adding the shorts and after files...multiplying the time invested...divided by the knowledge gained...equals....being a part of the best channel out there!
Love this channel so much. I appreciate all the time you put into these videos! I have almost gone through the entire backlog now after only discovering you, not so long ago. All I need to watch is the after files and shorts and I've done it! Seriously, you are awesome and can't wait to see how many more fans come along, and see all the new content! Thank you!
"45,000 km" in *whisper* got me 💀
I'm going down memory lane and rewatching your first videos. It feels like these 3 years have flown by. Thank you for touching on interesting subjects, and you give an unbiased opinion that stays neutral on controversial topics.
You have a gift, my friend.
The production aspect of your videos, the research, editing, animation, and your flow just works perfectly. I got through rough times because of your entertainment. You took my mind away from the suffering and put a smile on my face.
You deserve every dollar you make from your videos and ad revenue.
Stay safe, Your friend from Kentucky
Mind successfully blown, well played sir, well played!
Thanks, Jake!
Thank u🎉
This should be a required math class for children at a young age because it will open up and make them critically think so much quicker Well done
As you should know, math is a singular and maths is the plural.
So please do the right thing and if your first Language is English, use the word mathematics or if you are lazy, maths.
yanks are dumb as shite 😂
That’s exactly what I said! Critical thinking should be a taught skill.
Governments don’t want critical thinkers
I was lucky because my sixth-grade teacher recommended me for advanced math in the seventh grade and the school was using a new experimental math put out by the School Mathematics Study Group (SMSG) which concentrated on critical thinking. It was shortly after the USR had launched Sputnik and the US spent boku bucks on math and science education.
You are a child
Rewatching this in 2024 is so enjoyable! I recall this episode fondly and actually miss this format from time to time! Keep up the great work!
47, but my favorite math class was probability and statistics, and my favorite calculations were compound growth, decay, and permutations and combinations. It was the most fun math class they offered, the most practically useful.
Make sure you remember me when you inevitably get millions of subs
You will never be forgotten, TG!
Here they are years later, with millions of subs. @@TheWhyFiles
10! seconds in 6 weeks is a pretty cool coincidence, and not too hard to verify in your head. Of the 9 numbers from 2 to 10 being multiplied (we can ignore the 1), the 6 is covered by 6 weeks, and the 7 by 7 days in a week. The 3 and 8 are covered by 24 hours in a day, and then it just remains to figure out if the remaining 5 numbers multiply out to the number of seconds in an hour, which they do: 2*4*5*9*10 = 60*60 = 3600.
Love this channel! I seriously try to watch it every day. Thank you for doing all the research and keeping it so fascinating 😊
When I was in elementary school my teacher showed me a really neat trick for multiplying single digits by 9: hold out both hands in front of you with all your fingers visible. Think of what single digit number you want to multiply by 9; going left to right, use your fingers to count what that number is, and when you get to that number bend The joint of that finger and fold it down. The number of fingers you have to the left of that folded finger is the tens place and all the fingers to the right of that folded finger are the one's place.
For example, if you wanted to multiply 3 x 9, you would put down your third finger and have two on the left side and seven on the right side = 27.
That trick works with any single digit number multiplied by 9. Great to know if you have a kiddo in school
When the teachers rambled on like that id just yawn and look at my watch😂😂😂
@@Insert.anger50 ok. Hope you're doing good in life!
@@3RAN7ON yes im loaded still cant do math because i cant care about it
Great video! What puzzles me is a paper sheet 10mm thick. This means that the paper sheet is 1 cm thick. An inch is 2.54 cm. The average thickness of paper goes 0.05 to 0.10 mm.
Indeed, a "sheet" of paper 10mm thick would rather be called a shelf.
@@Dido01 exactly!!
I turned off at this point
I noticed that too. But then, if I figured it correctly, it takes only another 7 folds to get from .1mm to 10mm. So you'd only have to add 7 folds to each of his answers (starting with a .1mm thickness). Assuming the results given are close to correct, the concept of still only having to fold a little over a hundred times to get larger than the universe boggles my brain.
@@gportka8410 Exactly! I came to the same conclusion. AJ’s paper thickness estimate was off by a factor of about 100, but fixing the error results in what is basically a small, pretty much insignificant increase in the number of folds needed to reach the edge of the universe. Mind blown..💣💥!
Learned exponential growth and factorials in school, but your explanation of exponential growth and factorials retought me that in like 30 seconds where as it took me a week to learn it from school. Kudos to you The Why Files!
AJ whispering numbers in metric system after imperial system numbers - is something I need in my life.
421:873×5'829= 2:'459:097717 you know how i know this???? Because you dont need to know math you need to know where the calculator is😂😂😂
I discovered you only last month, but I'm binging now. Thanks AJ, this channel is amazing.
Just one more fun fact for #9.
The multiple table goes 09, 18, 27 ,36, 45, 54, 63, 72 , 81 , 90.
Love love love your videos!
I think he covered that by saying any multiple of 9 equals 9. Isn't that the same thing
@@sageminentjunky5197 no
@@sageminentjunky5197 Of course it's all going to equal 9 but did you notice to the numbers themselves?
"Finger trick" from middleschool. (I can hear Hecklefish from here.) If someone with all ten fingers was to hold their hands out in front of them and bend which number finger, the remaining fingers give you the answer. Times two would look like IiIII IIIII. One before, eight after.
That was the only multiples set quiz I got a 100% on. 🤦♂️
Ahh you nerds 😂😂 i hated math it was just a head cluck,🤔💥🔨 i hated high school math i was terrible, you get the exams and some of the questions were just like someone talking, i just write down ah ok have a nice day😂😂😂😂
very interesting stuff and professionally done!
Glad you liked it, John!
Found this channel. Fell in love. Had to go back to the beginning. Always loved math. Perfect place to start. My grade 13 statistics class had 30 people and not one of us had the same birthday. It was the first time in 30 years of teaching that ever happened to him! There was ALWAYS somebody with the same birthday in the same class!
Thank you for putting all your energy in your channel …
I LOVE YOUR WAY OF COMMUNICATING ALL THE KNOWLEDGE
Thanks for creating such worthwhile videos Why Files team!
You folks may enjoy my favorite palindrome: "Evil is a deed as I live."
This was first coined by the comedian Demetri Martin as the opening line of his 224 word palindrome essay, which reads exactly the same front to back.
This video was awesome 👏🏼 hope you remember I was one of your first 100 subscribers before your channel goes viral!! Can’t wait for future vids 🙏🏼
I will remember you, Icyy! You're a Founding Filer. I'm putting together a list now. What should we do? Free T-Shirts for the first 100 subs? What do you think?
Definitely a shirt or hat giveaway! I’d rock it!! 💯😆🤙🏼

Free Talking Hecklefish... I only discovered WF last year, but quickly watched every episode.
Hecklefish keeps my 3yo from making me change the video lol
The Joy of math is the best math book I ever read. It’s full of simple math tricks that will make your life so much easier
I'm sure that almost everyone said "47" and you're using a psychological trick to make us like you. I already like you.
Just watched every video on your channel...and I loved it. Love Hecklefish's facelift too 😁
Love this! (And your hair looks great!!!)
Thanks! (What's left of it) Have time to colab? I have characters to pitch you.

Ok, I started watching your channel 2 weeks ago. Finally, I made it to the end of the "ALL OF EM" playlist. Your channel deserves to be the biggest on RUclips. Now I can finally go and watch the podcast lol Thank you for all your hard work
Loving the videos on this channel! I've completely went down the rabbit holes with WF videos and loving every minute. This channel is gonna be massively popular soon!

@@TheWhyFiles you certainly managed to do just that 👍 love the channel
Excellent video, AJ.... and HeckleFish, of course. Your presentation was really well done, outstanding narration and the topics you picked were interesting, educational and engaging. Really well done, AJ! New favorite channel, to be sure.
You're awesome, Roberto. I'm grateful for you.
Love your videos, grateful to you and the whole team that help put these together! 👏
Great show. Love it
Hey AJ - try an episode on FIBONNACI numbers/sequence/series. It is the basis of the spirals in a galaxy, a nautilus shell, and many other things. Sort of a mathematical key to the universe.; the way things in nature grow. Big Wow factor in this one. Thanks for presenting one of the best channels anywhere.

I was blown away by this. Everyday after I would thing is it in this thing too? Random objects around my house
I’m impressed by your ability to fold a 10 mm thick paper so easily… 1 cm thick, that’s something!
When we have a piece of paper 10mm thick, we refer to it as wood!
@@wiseoldfool lol!
Should be 0.10 millimeters
I guess the metric system is too much.. ? 10mm thick paper?
Thats what I came to seek. Holy shii thats one heck of a paper. I should maybe check the math myself.

Omg recently got hooked on this channel and had to go back to see how it all started.. amazing and hilarious. You’ve come so far WF!
Just found the channel a month ago and watched everything. I love it! This was my favorite episode. Any chance for a part two?!
Wow, nobody's asked for that. I'd love to do a part 2 of this.
I second this.
ditto. this is great content
@@TheWhyFiles absolutely, more more, please more!
Yes please!
I just recently discovered your channel and after suggesting something that has already been covered, I have decided to binge from the first video on. I haven't even made it past the intro to this video but I am already excited to see what's to come. So far, I love your channel.
Also what's cool about the number 9- a transposition error, in data entry such as banking, is caused by inadvertently switching two adjacent numbers. A clue to the presence of such an error is that the amount of the error is always evenly divisible by 9.
No wonder the Beatles loved it so much. So much for the White Album " November 9 " Theory LOL
My new favorite number
Thank you for this very useful fact! I will tuck this away in my statement file for later use when I have problems balancing my statements.
Very useful when I was a young accountant!
This video is amazing. Great information delivered clearly and concisely.
The 9 thing is really cool. I remember being taught in school that if adding all the digits results in a number divisible by 3, that original number is, too.
Two?
So that's what John Lennon was talking about on the white album. Number 9....number 9....number 9.
I have quite literally just finished watching every single episode available on your channel in about 3 days. I can’t wait for a new episode! Best channel on RUclips!
I just love your channel. Entertaining and get to learn something.
Took a few weeks but got through all of them. Thanks for what you do, you make my work day bareable. :)
Such a great channel! I don’t know how I missed this episode but I have watched every other one. It is amazing to see the evolution of a channel like this. Thank you so much for all your hard work.🙏🙏🙏
I thought I was the only one that loved math this much :D And you write your numbers the same as I do. Love it.
Ive already watched and rewatched all these vids but i still keep doing it lol i love this channel man!😂
This was a phenomenal video, thank you
Amazing video. Only one correction though. The thickness of a standard paper is ~100 micro meters, 100 pages to get the 10 mm you quoted. Either way, factorials are very cool!
Glad to know I’m not crazy. I was thinking something was up with that one…but awesome video as usual!
Scott, thanks for saving me the trouble of explaining this. It sounded wrong immediately. For example, my wedding band is 6 mm in width., and it's a lot wider than the piece of paper.
Your best episode ever!! Being a math geek, I watched it four times straight, and I'll watch more soon. Keep it coming!
Love your channel man!!!
Great video. Thank you!
An absolute gem of a channel! Binge watching everything you've uploaded.
BOB! 🤣
Love the channel! Thanks
youre welcome human
Great episode. I really enjoyed this one. More please
Love your channel!!! ❤ Been binge watching all your videos. I'm horrible at math, but this was just so much fun! (I pictured Hecklefish repeating "number nine, number nine" throughout that whole segment 😄 ) Definitely subbed!

It’s crazy watching how fast this channel found it’s niche and blew up ! Easily my favorite channel to watch .
I always hit like on these videos, AJ I really appreciate you!
Excellent content and production; thank you !
The googolplex analogy to the weight of the earth is hopelessly understated. There are ~ 10^79 atoms in the observable universe. This is 21 orders of magnitude less than a googol. So, if you could represent 1s and 0s with single atoms, you would run out of atoms long before you got to that final 0. You'd need 10^21 times as many atoms as in the visible universe.

Does it have to be in triplicate again? Sheesh.
I like the one where you get a group of people to guess how many marbles (or whatever you have on hand in an identical large quantity) are in a glass jar. You take the guesses and average them out. The answer will be so close if not spot on the the actual number of items in the jar. Blows my mind. I saw this on a show by a mathematician talking about quantum physics. Great stuff 👍🏼
Wow! this is great! Thank you!!
Very cool episode! 👍
Loving going back to watch all these episodes. Love to see how you're evolving!

I just got through five or six binge-watching episodes till I got back through your whole catalog. You're really good at what you're doing and I hope you can do it for many years to come. (I hope we found some answers along the way as well.)
All of your videos are absolutely stellar. I liked this one the most tho. I’m not sure if it’s because it’s so different from your usual content or if it’s just because it’s so well done compared to similar videos by other RUclipsrs..
I just know I want more like this! 👍🙏🤞🤯
(I think it’s both)
You've come a long way .. great video I had not seen before
Subscribed to the channel a couple days ago. So glad I stumbled upon this show. Love Heckle Fish too.
Welcome aboard, Kimberly! Glad you found us.
Incredibly a nice video which many people should have a peek into this... Maths is just Magic.. and the way the video is presented is awesome...keep up the good work!
Thank you so much!
That was awesome. Thanks.
Love this channel so much. I've went al the way to the beginning.
So underrated channel 😭😭😭. The best maths channel I've ever came across . You deserve much more !!!! But that'll come soon I believe.
I appreciate that, Sakshi!
Even given background, the shuffling cards stats vexes my mind. You might find the "Trachtenberg system" an interesting bit ... about how to do calculations in the mind. Sincere thanks for the video - greatly enjoyed it - subscribed. Cheers
Another great show. I will re-watch any of your channels over and over again. Thanks to yo and Hecklefish and everyone behind the camera
had a blast watching vids last couple weeks wish I would have started on this vid and watched in order but I started on newest and just finished last one I do not have a ton of spare time so took me a min to get through em good stuff looking forward to more
I just don't know why these people don't get those many subs like those who don't really do anything but still get many-many millions of subs... This channel would appreciate way more
Nice video, I like the way how you present it and it's memorable, sometime even useful for life, not like school these days.... Keep it up :)
Thanks so much, 1ron! Maybe one day, the RUclips algorithm will smile on us...
