This is called "waterproof" :)

This is the coolest demonstration of Pythagoreon Theorem I have ever seen!

What an elegantly simple way to visualize this! I love it!

was only supposed to watch this twice in math class. had it going all day

A demonstration of the pythagorean theorem? *Brown* Perry the demonstration of the pythagorean theorem!

Back in 2017, when our math teacher introduced the Pythagorean theorem, the first thing he did was showing us this video. That was one of the best things he could do because this made (and still does) so much sense to me to understand this theorem.

Incredible, brought tears to my eyes!

Materials used were 1/2 inch gypsum board for the circle. 2x4 inch pine segments to support the back, as well as make the stand for it. Used a short half inch bolt, washers and nut to bolt the gypsum to the stand so it would turn easily. Used the “pencil on a string” trick with a tack in the middle of the gypsum board to create the circle. Used a gypsum knife to cut the circle, though any saw would probably do. Painted the gypsum white. Purchased plexiglass sheets from Home Depot, and had the squares (fronts and backs) as well as the square edges all cut with a table saw. Needed 18 pieces of plexiglass cut. It was key that they all that all of the edges be the same width, so we stacked up several pieces of plexiglass and cut them into strips all at once. It worked great. We used an arbitrary 1 inch width for all square edges. Drilled small holes in the gypsum then screwed the first three squares to the gypsum board, Screwing them in with screws, then dabbing them with silicone caulk so it wouldn’t leak. Then glued all pieces together with superglue, cutting and drilling as needed as a we went along. We added blue food coloring to the water to make it easier to see. All material was purchased from Home Depot. Lowes would have the same thing.

I love the sound the water makes.

cant wait till this is in cinemas

Also, if you dropped a perpendicular from the right angle vertex to the far side of the large square, it would cut the large square into two compartments equal in area to the two smaller squares. You could then use two colors of water to show this. This would be closer to a demonstration of Euclid's proof from the Elements.

This is a really helpful visual example! Thank you so much!

This is probably the best way I've ever seen to explain the Pythagorean theorem.

Brilliant. No words needed. Well done!

Brilliant idea to demonstrate this fundamental principle. 👍

Absolutely awesome!

THIS ACTUALLY MAKES PERFECT SENSE! COOL!

Captivating truely. The special effects really brought this piece together. There would need to be more dialogue however from the budget and the materials in which the director was given this truely was a film for the ages. Overall the filming and decision to have the camera slightly off centred showed true emotion of all the characters. While the plot was confusing to start with the subtle hints throughout made it clear to the viewer the main characters true intentions and reasons for their actions. This film got very inappropriate towards the end and I would not recommend watching it with younger audiences however if you wish to see a very well thought out and beautiful piece of art I highly recommend this video. We truely did learn the true meaning of friendship and the ups and downs of high school football. Thank you so much for producing this film that admittedly did make me shed a few tears.

I wish everything in math could be shown in a simple way like this!!!!!!!! :((((((

A very creative way. Appreciate u

Absolutely amazing. Thanks for making me really understand the theorem today! Real genius! 🙏

This is Awesome!

This is awesome. You are a genius. Thanks you

Cannot be misunderstood... multilingual... not one word wasted! BRILLIANT!! 😊

6/10 the dialogue wasn't very rich and I feel like the main character didn't have enough lines. And the special effects were mediocre at best, and can somebody explain the plot to me its very confusing.

this pleases my grade 11 maths class very much, many thanks :)

It's also assumed that the depth and width of the containers are the same so the volumes are proportional by a factor of c^2 / (a^2+b^2) = 1 which actually proves pythagoras's theorem (assuming c is the hypotenuse etc. )

Amazing, never would of thought of it!

One of the best ways of demonstrating this idea that I have seen, well done.

I cannot explain why, but this makes me happy. I think it's just because I had never thought about Puthagorean Theorem this way before, but this makes total sense.

A lot of thanks! It helped me a lot :)

A 43 second video finally put some logic into a thing my teachers couldn't.

Very nice. Simple, yet elegant

Instructions unclear, failed Geometry class

Thank you very much 👍👍 I am going to use this video in the presentation in the class to prove the pythagors theory

That was really ingenious. Good basic ideas that help the student into geometry ❤

that was actually quite beautiful.

this is cool but didn't answer the question my teacher attached to it :')

Cool demo. And love the channel name.

Awesomely explained.

I never understood this video until I looked up the meaning. The Pythagorean Theorem says that you can take the square of the two leg lengths and they will be equal to the square of the length of the hypotenuse. Thats the same thing as finding area of a square (squaring one side length). For this reason, the space that two of those smaller squares takes up should be the same as the space that the larger square takes up. a^2 + b^2 = c^2 OR area of square 1 + area of square 2 = area of square 3.

This very well answered the question i gave my teacher of "Why do we multiply each side with times 2 instead of just multiplying each side as it is?"

This is perfect, it’s a great explanation of Pythagorean theorem, this 15 year old classic is a masterpiece 💖

Beautiful.

is there one of these for taylor series

Very satisfying explanation!

Hello. I get to do exactly the same, I mean the theorem with water and stuff so Just wanted to ask a question and how is this possible? What materials are needed cals? I appreciated very much if I could work with this THANKS

Beautiful!

I came here because of math class, now it's time for me to go back to work

Pythagoras smiled from heaven.

Thanks this was very useful

I’m 4 years into engineering university and now is that I understand the intuition behind this. I always just took it as a fact, but now I understand the concept more clearly.

Thank you! The Pythagorean theorem is actually one of the things I still remember from high school, however I wish I had watched this demonstration back then. How easily would it be to understand.

Instructions unclear - completed stereo madness

¿Alguien sabe como se hace y los materiales que se necesitan? Necesito hacerlo

This is fantastic!

Shoutout to mr.crouse who sent this to all the grade eights

damn and now I have to go to the bathroom

Brilliant! Every math teacher should use this video when presenting the Pythagorean theorem to students.

Fourier series can be clearly?

Amazing proof of Pythagorean theorem. Good teaching resource.

How did you make this?

Ok this is honestly pretty cool

this is pretty hecking cool :0

Nice one :-)

Anyone else from math class😭

WOW qué ingenioso!!! Me encanta!

please tell me what is that transparent object in which the water is

I'm going to be a math teacher and this demonstrates the pythagorean theorem so well, where can I get one of these?!

i had to watch two times to understand the proof. said being that I'm studying calculus 2 at the moment.

how do you make base plz answer me

where do i get the materials !!

Someone should point out that the boxes are perfectly square ex: 6X6X1, 8X8X1, 10X10X1 for this to work and be true.

Can you please show how to make this ?!!

That's great!! Bravo!!!!

Very well done!

guys, can share us on how did you construct it? It would be a big help! Thanks.

god damn my class is confusing

How do we make it can u show plz

where do i buy this it’s so cool

I need exact measurements for this project

Watched this in class

This is creative!

How to do this

wait, i want to pee.

I like eating poles made out of trees

Amazing!

Wow! Great idea!

very emotional, im touched.

*_a² + b² = c²_*

Where should the triangle sit (where is the centre of the circle) to have the two far corners of each square touch the same circumference?

Boa noite.. Onde consigo esse exemplar? Tem tutorial de como fazer ?

Poor girl was probably kidnapped

who made this cuz this is cool look how much peeps have watched it

Waterproof analogy

I vote this for E3 contest. Big ups!

For the confused people: 1. Get a piece of paper and a ruler to make straight lines and to exemplify the techniques I will list. 2. Squaring/by common name, Squared: Squaring is symbolized by a little 2 to the top right of your number. Squared means 2x2 or and other number multiplied by itself. For example: 2²/2 x 2. 3. The Pythagorean theorem trick: is too (on a calculator or in head) square both legs (two sides the make the right angle) and combine them. After doing so, square the hypotenuse (the one that slants to connect the 2 ends of the right angle) and find the square root. If the two answers (one from the combined legs are equivalent and the hypotenuse's square root) are equivalent the the triangle is a right triangle. You're welcome. 4. Confusion on the squares: you can break down a triangle easily...there are 3 sides (which are in measurements) and each one needs to be squared, for example: 2 inches TIMES 2 inches, take one of those 2 inches and put it into the height of the square, take the other and make it into the length of the square. BOOM! that's how they got squares. You're welcome. 5. The legs of a right triangle are the ones connect to the little square in the corner, this represents that there is a 90 degree angle from leg to leg. 6. The hypotenuse is the slanting line that connects the two ends of the right angle, this will also be the longest side of the right triangle. 7. The Water Demo represents the trick, the squares are just the measurements of the lines squared. So if those L squares (the squares representing the legs) are filled with water than we can see if they are equal (when combined) to the hypotenuse by transferring the water. Now you have Squaring, Right triangles, Mathematically Creating a Square, and Pythagorean theorem trick consolidated into 7 short paragraphs. You're welcome.

This is an excellent proof

Brilliant!
