I am a maths teacher and I am constantly learning pedagogy from the best on UA-cam, and encourage my students to do the same but for the maths. This guy is the nuts.
Hey, thank you so much for this. At this time of writing the world is deep in coronavirus, and I'm figuring how out to make math lessons more engaging for my students in the future. Your enthusiasm is palpable - I am looking forward to getting back in the classroom!
To me, the most fascinating aspect is how the geometry can be represented in an equation, and how these proofs can be used to aid the construction of objects, even in ancient times, whether architecture, clothing, transportation, or whatever application was at the frontier of innovation. Even now, geometry knowledge is gold, for many careers or hobbies.
The fact that you know something does not automatically entail you can teach the subject to people, and this is the biggest problem in many schools. The only way to teach something is to generate interest in the listener. Eddie has done more in a 10 minutes video that my math teacher in 5 friggin' years.
I wonder if you could derive pythagoras from first principles in abstract math. I'd like to compare it to mine which also proves Fermat's Last Theorem.
Hello Teacher Eddie, i am happy in your teaching. We use big side as 5 (Diagonal) intermitted side =4 (Opposite side) Smaller one = 3 ( adjacent side) 3(square) + 4(square) = 52(square) Sum up: 9+16 = 25 25=25 tada..... tada.....
c=a+b c^2 = (a+b)^2 = [a^2 + b^2] + [2ab] (binomial expansion) c^2 a^2+b^2 The "proof" in the video is only valid in Eddie Woo's imagination. (Pythagoras was also confused).
I am sad that u r not my secondary school teacher. If u r, I will have learnt the fun of math instead of just memorising what I have been told to. Learning math should be like this, understand and apply. Too sad to say that Malaysian education has fallen behind too much, hope to see improvement in our level of teaching. Good job, Sir.
I have been good in math, but I never realise learning math can be so fun. Yes, I did get good result in all my math exam, but basically I just memorise what I have been told to, memorise exactly what I saw in the textbook. Learning maths is more than this, understand the basic and the meaning of it is more important.
Are you familiar with dimensional analysis Eddie? Why not also state that a rectangle is not the only shape that applies to this theorem. Semi-circles, circles, a regular pentagon, a regular decagon , a regular polygon can replace your square, in fact, it works with any similar shape. However, with diagrammatical proofs or with nines complement there is no indication as to why? Can you suss it out Eddie?
Simple, the area when scaled changes proportionally to the square, so the area gets multiplied by the square’s. s(a^2)+s(b^2)=s(c^2) works out to s(a^2+b^2)=s(c^2) and then we divide both sides by s to get the pythagorean theorem.

1:31 "If you got it wrong, no big deal, that's what rubbers are for!" Amen, Mr. Woo... amen.

there are several meanings for the word "rubber" :-)

he is a legend ! How he sees this simple proof is great!
It's not a proof but a really nice visualization.
mathOgenius This way of proving has been around for centuries.
@@IlValentino100 It is a visual proof
@@noodlery7034 no it's not, that's not how proofs work in mathematics. it's a visualization nothing else.

Loved the magic trick... go to right came off left------Legend
Anyone else excited for part 3?
No🙄
Your videos are really awesome Sir.You make things very easy to understand.
Keep going sir.
In school we got only told to use this form not how it really works... this was just a mindblowing moment for me thanks :D
Love your teaching from Burma!

Sir it was really helpful thnx for posting such a wonderful lesson teaching.
Dear, what a wondeful teacher!
It is awesome I learned many things about Pythagaros theorem
love watching math videos at 12am 🥳
you broke my browser, somehow :(
HIHIQY1 awe sorryyy😂
Brilliant teacher
Great stuff! I'll watch part one now... And then three. Thanks Eddie!
Looking back my math teacher had some bloody patience with me but I so with you where my GCSE math teacher.
Perfect explanation 😊
Never dreamt mathematics could be so beautiful, you are a magician☺☺☺
happy in your different method of proving👍👍👍
He has so much energy
2:12 Did he teleport? Is he secretely the flash?? Is there some sort of portal??? (Look at the clock)
Nice try the minute clock changed its position by a minute or 2
Always knew he was supernatural
Ever heard of editing and stuff?
Broooooo I was thinking the same thing. I was searching in the comments to see if anyone noticed.
I wonder if you could derive pythagoras from first principles in abstract math. I'd like to compare it to mine which also proves Fermat's Last Theorem.
Nice explanation sir ..
He rubs things off all the time. ;)
A very interesting proof.
Hope these kind of teachers in INDIA.
2:12 can all math teachers teleport?
the clock too didn't change much...
how does he figure out how to cut the pink rectangular in that specific way? what is the idea behind?
Really beautiful 😍
you are the only reason I am beginning to like maths
Mr Woo, tiling a torus
Michael Stevens has entered the chat
Could you have cut up a^2 and placed its pieces in c^2, instead?
I am a 55 year old engineer and my mind is blown.
Yes !
Hello Teacher Eddie, i am happy in your teaching.
We use big side as 5 (Diagonal)
intermitted side =4 (Opposite side)
Smaller one = 3 ( adjacent side)
3(square) + 4(square) = 52(square)
Sum up:
9+16 = 25
25=25
tada..... tada.....
Yeah, It's awesome how there are proofs for this theorem that make sense for right and left brained people!
Sam Anna, there are three or four different ways to prove ....and it's more convincing to kids if taught in all different methods.
52 square is 25?
@@TheDeathLove not at all.
Wow 😮
Good
Can u come in India ..
I wish you were my teacher
FINALLLLLLLLLLLLLY
c=a+b
c^2 = (a+b)^2 = [a^2 + b^2] + [2ab] (binomial expansion)
c^2 a^2+b^2
The "proof" in the video is only valid in Eddie Woo's imagination.

first comment, during physics :)
If you got it wrong - it means you should have used a rubber first :)
This classroom looks like our math teachers classroom

I swear you explained this in another video, am i wrong?
2:13

1:40 giggity...
Beep beep lettuce
2:12 he teleported to the other side of the rooom.
and even the clock didn't change much...
Isn't this a primary school concept?
No, secondary
i think it is a primary school thing i knew this in year two
I cannot understand anything. He is speaking very fast
If u were in India the students would be teaching u
The date in the corner is proof that Australia is in the future.

By 2 months?
Wtf?
I wrote my date by dmy as well, but on my PC the date is always in mdy, but I am lazy to change it XD
No, Americans live in the past
You get it wrong it's a European Dat meaning to say that 9/2/18 translates as the ninth of February 2018.
Mr woo you should do videos with Lil pump
Love frok india sir
I can prove it better than this
Yeah right
Okay...
It's not even a proof...
Shows us then
It's a visualisation.
