Happy Pi Day!

[@qwertyTRiG]

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.

Measurement and pure mathematics. They're ghosts. Consequences of our perception. You can build a religion on this.

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.

Thank you professor Eddie for your channel . It explains math in a very simple way.

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 ❤

[@Miss.Princess8765]

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...❤❤

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!)

[@cholo6531]

Mr Woo is the goat!

[@wilfredkube8570]

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.

[@DeJay7]

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!

[@SankalpaSatyal]

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

[@dawsontate2989]

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?

[@rubiks6]

It's created by God and discovered by Mankind.

[@snehshah887]

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....!!!

[@ValidatingUsername]

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 😊

[@macethorns1168]

July 22 should also be pi day. 22/7=3.14

[@briandeschene8424]

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.

[@pagetvido1850]

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.

[@user-zr6pl6nb6z]

The radius would be 3.81 hours of circumferential length.

[@pagetvido1850]

@@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.
