For those who might be interested in what’s going on, this is a demonstration of how the distribution of results from a series of binomial trials (in this case left or right) will tend towards the normal distribution when repeated enough. If it’s something that piques your interest, take a look at the central limit theorem; really interested bit of maths going on here.
tacolength In the era of the internet, you don't need to pay for a course to learn highly advanced math. To get credit for it towards a degree or technical certification, yes, you need to pay for a course. But if you just want to learn for the sake of learning, free online resources can be just as good as a traditional classroom setting. Sometimes better.
Random walk problem in one dimension, with equal probability of going left or right in each step. Therefore Bernoulli trials generating a binomial distribution, that in the limit of an infinite number of steps gives us the normal distribution.The issues with this toy is that the ball bearings interact with each other and the horizontal range is fixed.
As a Science Fair project that I did one year my Dad helped me construct a much bigger plexiglass Galton Board which ball bearings fell into and made the same bell curve pattern just like what your smaller version did in this video of yours. Too bad that I didn't experiment more with board so the judges marked that my project was more of a demonstration than as an actual experiment which hurt me from receiving a more coveted Science Fair prize. But at least I got a B+ with my project, which of course never hurts anyone
Technically, the distribution is the *binomial distribution* and that is why there's Pascal's triangle there because it's intimately connected to the distribution. However, you weren't that far off, in the limit where you have infinitesimally thin compartments the binomial distribution converges to the normal distribution so that's why people just interchange their names freely. Also the Pascal triangle drawn on top of the pegs tells you the number of paths down that take a bead from the top corner down to the corresponding peg. For example with the first number 2 there are 2 paths from the top corner to there. Not trying to be pedantic, just providing some insight because people seeing this for the first time would probably think that it's just a fancy decoration with no relation to the underlying process
I know each of these rows as the coefficients of (x+1)^n, where n is the corresponding row of the triangle. (They’re not quite the same: the top of the triangle corresponds to n=0.) That is: (x+1)^3 = x^3+3x^2+3x+1
Ah, Sir Francis Galton, you might have been the father of Eugenics but you were sure a smart cookie in other areas. Regression to the mean, biometrics, fingerprinting, meteorology, all have had an impact by the man.
You're right, because the Fibonacci series is not featured in Pascal's triangle, because its structure is different. The Fibonacci series is exponential, whereas diagonal lines in Pascal's triangle are polynomial.
It is possible to obtain the Fibonacci sequence from Pascal’s triangle however, by adding up numbers along the diagonals. Starting from the left hand side, if you add up all of the numbers that are connected by the lines at 120degrees, these will add up to the corresponding term in the Fibonacci sequence. Starting from the left most numbers will give you the odd terms of the sequence, to obtain the even terms, start from the second diagonal (the 1, 2, 3, 4, etc). It’s a bit fiddly for the first few terms, but is a bit clearer once you get further down the triangle. For example, if you start at the 4th 1 down the left hand side, it is connected by the 120deg line to 6, 5 and 1, and 1+6+5+1=13, the 7th term in the Fibonacci sequence. Edit; I’ve just watched the video again, and you can briefly see at the start that this process seems to be described on the side of the box.
I am subscribed to both Grand Illusions and Numberphile and today both channels released videos that called out the golden ratio and I just watched them back to back without knowing this beforehand.
No, Tim, they are not ball bearings, they are bearing balls. A ball bearing is a complete assembly of balls, including inner and outer races, cage, and dust shields.
Hmst'd've, intresting Awesome!!! 1:22 toy for *statistic boy!* 2:49 Hopper (UK) means funnel (US). Wow, I learnt new vocabulary!! Duper Awesome!!! Right?
Happy coincidence...I sub to Numberphile as well and they released a video today on the Golden Ratio and "why it's so irrational", which I'm about to watch.

I'm so bossy, chap, get off me It's a different jingle when you hear these balls, see?

and if you have the money takes a statistics course

I love Tim. He is just such a happy little old man and it just warms up my heart.
Ahh Tim
Making another day great by showing us your collection

2:51 that was almost perfect.
Thank you so much for this video. This item is £40.00 from Amazon so you saved me a lot of money with your excellent illustration.
Fascinating. A peak at how the universe follows specific rules. You would think the distribution would be random.

Why do i find these videos so entertaining they are fun to watch
There's a giant one at the Henry Ford museum here in the Detroit area. It's quite mesmerizing to watch
Unbelievable demonstration
this was allways one of my favorite things in math and I love that I share this interest with Tim. Mabye I will buy one of these myself one day :)
Your videos are super calming especially to watch before bed. Thank you for making such fun videos :)
Showed this to my statistics professor. He was actually thrilled and wants to buy one
I still don’t understand why this is so entertaining but god damn do I love this man
I AM EARLY TO SEE TIM DO REVIEWING YAYYYYY
Poppies Popplio, it says your comment has been here for 16 hours....then on the video it says 15 hours...you were really early. Lol
what is he on about with the fibonacci series? I cant see it anywhere. I mean I can see 2 1's, and a 2, and a 5, etc, but not in any sort of order.
Diagonals of the Pascal triangle add up to Fibonacci numbers.
the numbers arent actually on the triangle, you need to add them: www.maplesoft.com/view.aspx?SI=3617/pascaltriangle1.gif

Nice, ty for the link.
I know each of these rows as the coefficients of (x+1)^n, where n is the corresponding row of the triangle. (They’re not quite the same: the top of the triangle corresponds to n=0.)
That is: (x+1)^3 = x^3+3x^2+3x+1
Man I love these sounds
are my eyes messing with me or was 2:52 a close to perfect fit for the normal curve
Ah, Sir Francis Galton, you might have been the father of Eugenics but you were sure a smart cookie in other areas. Regression to the mean, biometrics, fingerprinting, meteorology, all have had an impact by the man.
Very mesmerizing. That must mean that with things like pachinko, it's the best idea to drop the coin above your target.
Lovely stuff,Tim
That looks so satisfying.
when you think he's about to say "wow" but he says "oh my" 3:05
You could put a piece or cardboard or something under it to tilt it slightly, to see how it affects the distribution.
Use Norm CDF to find the area under the curve
I don't see the Fibonacci sequence in the diagonals.

Thanks for that, Lipm, I've never noticed that before :)
Avogadro!
Michael from Veauce has done a Video bout it on DONG channel
Cheers, Tim!
This is also a good demonstration of chaos theory
How about a game of Lucky Hit?
you are THE MAN tim !!!
I wonder which child would play for hours with this toy ! Very interesting for older children though ! Excellent !
Can someone tell me the odds of the board doing pretty much the opposite of what the normal line says?
I am subscribed to both Grand Illusions and Numberphile and today both channels released videos that called out the golden ratio and I just watched them back to back without knowing this beforehand.
I think that was fascinating.
If We had Infinite Balls Probably It would Fit The Curve Perfectly.
But No one Can Make That Possible in Real Life.
Tim knows his math !
Don't miss the single brass ball! It demonstrates the variability of a single X.
You know you hit the big league when Vsauce makes a video after you show a toy.
... where is the Fibonacci sequence? I can't find it
very interesting toy!
Love your curious thingamabobs
Interesting. Thanks for the video.
Excellent and Thank You Sir.Using it for training.Very useful.Hope you do not have any objection.Please permit
Wonderful indeed!
Tim is the Legend27 of toys
I heard Tim27 once completed Ball in a cup on his first attempt.
Been a while since I've heard that meme

Its a visualization of Normal distribution some say Guassian distribution.
No, Tim, they are not ball bearings, they are bearing balls. A ball bearing is a complete assembly of balls, including inner and outer races, cage, and dust shields.

1:22 toy for *statistic boy!*
2:49 Hopper (UK) means funnel (US). Wow, I learnt new vocabulary!! Duper Awesome!!! Right?
ur the first comment yay
I wonder if a tilted table would artificially add mass bias towards the edges of the parabola 👀
Very interesting! But I don't think I saw exactly where the Fibonacci series was...🤔
is'nt that d pasca's triangle??
This thing is great!
There needs to be one that can also demonstrate wave interference and then another for photons.
Tim we want more :-)
This is the best stuff to watch when...influenced by things, shall we say
Erich Don't be a wuss, no-one will come get you for saying you're high on the internet🤣
Isn't that called Tartaglia's triangle?
I thought this was going to be boring. I am glad I was wrong.
Happy coincidence...I sub to Numberphile as well and they released a video today on the Golden Ratio and "why it's so irrational", which I'm about to watch.
There was the perfect one at like 2:50
Can u show toys from Romania?
I dont get how this work?
We love you
Very cool
Oh I want one!!!
Ah, very nice!

It's a different jingle when you hear these balls, see?
Your GB's missin' an I, fella
Your balls missin' a curve
