Had a ton of fun watching. Thanks.

Great video! Very good content, thanks! Maybe if you use graph paper, the accuracy will be easier and higher.

👍👍! Love the homemade compas. I made mine as well. 👍

that was quite interesting... you made a right triangle with sides 2x and 1x, thus the hypotenuse is x√5 (x is units)... then the 1u got subtracted from x√5 leaving us with (√5 -1)x. So basically you constructed to touching circles one with rA = (√5-1)x and the other with rB = 1x Then we have 2x = rA + rB = (√5-1)x + 1x, thus x = φ! Now... we can have a Golden triangle, which hypotenuse is φ and the other sides are 1 and √φ (directly from the equation: φ = √φ + 1 or φ² = (√φ)² + 1², which is a right triangle by Pythagoras theorem, a Golden one)!

Very interesting! I suggest you consider a REAL compass!

Beautiful ❤️

Thank you...

I see comments that suggest John needs a better compass. John is a mathematician, not a draftsman, I think that is clear. I have built several wooden shop built compasses that are similar to the one he is using and quite frankly they are as accurate as my professional compass.

89 and 144 are Fibonacci numbers. My construction was off by a millimeter.

( 1 + √5 ) / 2 = Φ and by the way..... it have nothing to do with humans..... it always existing in the universe..... 🌏 📡🌏 👣🕘 💎👽☠☼☾☄ェヽ・ㇺㇾㇽ₪ɨʈɨЬɨʀа₪ヽ・ェㇺㇾㇽ✶☥✨🌛🌄⊀✶⋊🐺🐾☆🐜🐜▲▴◭

Hi, John. Who makes that compass that you are using?

dear, you can get on amazon. search and get .... love you.

dear , can you teach me. i am about to start construction my sweet home....can we do sample architechure online.....please let me know....love you !!

144/89 is nice approximation and comes from Fibonacci sequence You were close to this

All though I did enjoy watching this, it does seem an incredible convoluted way of doing it, and furthermore I'm not sure I entirely understood your proof. I'm sure I've missed something, but it seems to be that you claim 1+1 to be equal to the square root of 5, which is of course not accurate. Of the top of my head, I'd use much the same process as you, drawing a right angled triangle ABC, where |AB| = 2 and |BC| =1. Form there of course there are multiple avenue. You can extend the hypotenuse by one and bisect, you can subtract 1 from the hypotenuse, bisect and add one, and so on. At any rate, it would see I didn't quite follow, but I think I got the gist of it.

@13.40, anecdotally!! not antic-totally =(

I enjoyed this construction. Some constructive criticism: If I were your student, I would want more explanation of what you are doing and why. You bisect the line segment, but you never explain that you are envisioning the line segment AB to be 2 units. You don’t explain that you are creating a unit circle with a radius of 1 unit to construct a right triangle with leg lengths of 1 and 2, therefore a hypotenuse of 5^.5, or why 1 unit from the vertex at D is the length your looking to bring to line segment AB. Take it or leave it, overall I enjoyed your presentation, but you spent more talking about the proof and percent error than what you were actually doing.

Not surprising that I found algebra incomprehensible at grammar school.

Yawnnnn.

Too long video.

Why don't you buy a decent compass instead of using the piece of junk you are using!
