That was a beautifully coherent and straightforward definition and discussion. You always bring such great clarity to teaching. Pi isn't magic: it comes from somewhere.
Beautifully explained.. I've always wondered why do we even use a number whose value doesn't terminates . But the way you explained cleared the origin of pie, in my mind.. Love the way you teach mathematics.
Sir I really reallyyyyy love the way U teach, it is soo easy to grasp the concepts and the idea of how the things were discovered... In school they don't teach these things (only teachers who are interested they do), teachers there only teach what is pi (for example) and teach how to use it for calculations.... Sometimes they are in hurry to finish the topic, sometimes they don't want to teach etc... Basically they don't teach U how to visualise the things that they are teaching... I was in 10th (2023-24 batch) and I used to watch those 11th standard topics that U taught to Ur students and truly I used to understand everything... Seriously sir I love the way U teach..❤❤ Thank you so much for making these videos and helping other students as well sir...❤❤
The universe is so well structured Subhannallah, brings me joy to hear about mathematic laws explained like this, thank you greatly Mr Woo. May God guide you ❤
I am a big fan of your teaching style. Happy Pi Day to you. In our school as well, we celebrated Pi Day today. Enjoyed your video. Please keep on inspiring. Oh and by the way, in this video, each person will get 2/6 or 1/3 of the bar and not two-thirds, right?
I enjoy explanations which are easy to understand, and are presented in an enjoyable “fun facts” way. This demonstration showed the relationship between the diameter and circumference of a circle, and that the ratio between them is expressed by the number “Pi” or π. An explanation was given for the way in which the word “diameter” came to be used to describe the distance between two points on the opposite sides of a circle. This was a very good and logical explanation. But what about the circumference of a circle? There are two other words which could be used to describe this distance - perimeter, and periphery. Each of these words has Greek language origins, and it is helpful to think of “Pi” being related to “PERIMETER” rather than “Circumference”. Another “fun facts” presentation could be about the derivation of the angular measure called the “radian”, which is 57.29577951 degrees, or 57 degrees 17 minutes 44.81 seconds of arc. If we multiply this number by “Pi” we get a result of 180, or if we multiply it by 2 times “Pi” we get 360, because there are 360 degrees in a full circle. This is just another way of expressing the formula for the circumference (the PERIMETER) of a circle being 2πr.
Thank you. You are slowly (by proxy), teaching Maths to someone who obstinately refused to learn his times tables and hated Maths, yet still managed a degree in biology, a masters in ~soil science and a good crack at a PhD (3 years), in plant physiology (a feat no longer possible, bloody physicists are taking over all the sciences).
I wonder if Eddie thinks there are any solutions to the problem of adding two vectors together that equal a third vector where the nth roots, n greater than 2, of the each of the vectors are all integers 😊
Earth's orbit is (fairly) circular. July 1st marks completion of "π days" of any given year. Circumvents (pun intended) cow-towing to American date format. Still, a good exposition (if one ignores the importance of a circle's centre and radius... Long live Tau!)
Sir, I am from India and preparing for the IMO(International Mathematics Olympiad) although I am still in Grade 5. Sir in India There are no teachers like you. Hats off to you sir. Could you tell me in which center you teach children in Australia?😅
I paused the video to put this comment: Did you see? DID YOU SEE? …how straight a line he drew freehand after marking the two points for the circumference? That was impressive.
The ending is so key. Pi is not only found in the relationship of a circle’s circumference and diameter, but also other parts of nature, our world, and even space. Is math created or is it discovered?
Just a question here, if we say that Pi is number comes from ratio of circumference to diameter then by definition it should be a rational number. Then why do we say that Pi is an irrational number?? Or may be originally Pi is not actually came from division of Circumference and diameter....!!!
@@user-zr6pl6nb6zTrying to apply math to every day life. Although I don't think a radius makes much sense to think about on the day cycle. I suppose the radius doesn't make a lot of sense in a lot of situations, except for pie charts. It's just useful because it connects to the area, volume and circumference of a circle I guess. The circumference is where it's at :) it has a lot of meaning in a lot of different contexts.
I'm jealous; I have a small bit of Chinese ancestry via the native Americans but math was a foreign language to me, now I slightly like the puzzle solving aspect of it. Mental math however; there's no way I care about that one iota; it's masochistic.
Pi day for math. May 17 ( the 137th of the year) for physics. And October 23 for Mole Day for chemistry. I can't think of a good number for biology, Feb 23 for 2x 23 chromosomes?
Hi Eddie woo it’s Jacob are you the guy from play school and all so Eddie I like Maths 🧮 as well 👍I like your videos too 👍keep up the good work you are doing great Job Eddie 👍from Jacob McAndrew 👍
It is, but some maths youtubers upload videos like these a day or two in advance so that teachers can prepare pi day lessons that have these videos integrated into them

Measurement and pure mathematics. They're ghosts. Consequences of our perception. You can build a religion on this.
Your enthusiasm for mathematics is honestly inspiring - great video!
My man I watched your video on permutations and combinations from 9 years ago yesterday and this popped up today, you haven't aged a day.
this is too real
May teachers like you live for 100s of years!!
Happy π Day, Professor Woo! Thank you for your channel!
See you on Mary-Jane day (4.20) and Star Wars day (May the 4th be with you)!
Thanks Professor , you are great ! And Happy Pi Day ! 🙏
Beautifully explained..

Before watching this video, pi day was just another boring day for me but now it surely is congruent to the coolest thing ever!!! Thanku Mr.Woo ❤

I just learned where the word "Diameter" came from today, thanks Eddie and Happy Pi Day!
Man love they way you teach even tho this is basic knowledge
Thanks Professor

pi = ratio of circumference to the diameter of the circle
I wish I had had you as a maths teacher when I was in school; maybe I wouldn't have given up on it at 13.
I wonder if Eddie thinks there are any solutions to the problem of adding two vectors together that equal a third vector where the nth roots, n greater than 2, of the each of the vectors are all integers 😊
OMGoodness, I've been pied. Thanks Professor Woo :)
Happy Pi day, Professor.
Mr Woo is the goat!
Aussie Legend
Pi = Circumference/Diameter is because Diameter being a measurement which can be made unlike the radius otherwise we'd use C/r as its more logical
What I'm most intrigued by is how and even more so why π is related with complex numbers. Because it is, and it is weird.
Happy π day!
Sir aged like wine, u are still so fine even nowdays
Bro didn't let March 14 to mature.Dropped the video in its infancy.

A very nice video as always, could you also make a clip that covers the discovery of "0"? 😊
A better choice for people with a real calendar is 22nd July. 22/7 is closer than 3.14
Secant, tangent, cosine, sine! Three point one four one five nine! 🥧
If there was one more day in April, pi day would be 31/4 in large parts of the world!
I like the fact that my entire feed is now pi day

It's created by God and discovered by Mankind.

July 22 should also be pi day. 22/7=3.14
Nice that you noticed that, it would be cool!
happy Pi day Eddie woo!!!!
Hmm, so if the cycle of my day has 24 hours in it, it's radius is 3.81? Not sure what that would mean or what unit of measure it'd have.
The radius would be 3.81 hours of circumferential length.

He's Australian and timezones are a thing
Just ask what country you are in and what country he is in because it is pi day in Australia. Greetings also from Australia.
Pi Day is just a promo for pie and pizza sellers nowadays. Yay capitalism! 😅
Why doesn't pi ever end as it is comes from a distance and it should end with distance
