If you are a mathematician, this video is not for you. If you are a visual thinker, this will explain everything your Math teacher left out!
When you find out how the value of Pi was discovered, it will change your whole idea of Math and Geometry. Teachers tell you that Pi is about 3.14 but they never explain why. Visual thinkers need things explained in another way and this will explain it so you go OH! Now I understand!
Follow the instructions and you can make your own Archimedes discovery of Pi to amaze your friends with.

I always learned: "Circumference = π • diameter" I always thought everyone understood pi as being the ratio between the circumference and diameter of a circle, but this video brought back a memory. When I first saw someone write C=2πr, I was so confused why they used a more complicated and abstract formula. C=πd is so much simpler and tells you explicitly what you showed in this video. It makes sense if you learned C=2πr, you wouldn't get the same intuitive understanding of what pi is. By the way, I would recommend you measure the diameter instead of the radius, because measuring the diameter gets you a smaller relative error of the measurement.

@petestevens9740 2 жыл бұрын

This is a really nice explanation of what Pi is / where it comes from. It is NOT a demonstration of how Archimedes determined a more precise value than "a little more than 3". Pi is only approximately 3.14, and Archimedes didn't have access to numbers written in decimal form anyway - they hadn't been invented yet. He was able to work out (using a very brilliant geometric method) that the number of diameters it takes to equal the circumference has to be between 3 10/70 and 3 10/71. That was enough precision for him, and it gives us 3 1/7 (22/7) which is about 3.148. Would love to see you make a video showing that method!

Nice video. If you do this again, right around the six minute mark of the video, when you were getting three and a half and a then three and a quarter, measure the line with your ruler... to that mark... and divide that by the diameter of your circle. Use that as your decimal. You wrote down 3.14 out of nowhere because that was what we were told pi was in school. The straight line distance divided by the diameter of your wheel is the way to go, if you don't know about 3.14 ahead of time.

@billshiff2060 Ай бұрын

22/7 (3.1428) was Archimedes upper boundary for PI not PI itself. Archimedes said PI lies between 3.1408 and 3.1428 which is approximately 3.141. Of course he stated it in fractions not decimals. 223/71 < π < 22/7 or 3.1408 < π < 3.1428 So pi must be ~ 3.141_

I figured this out in 4th grade by experimenting with various coins as my “wheel”. We hadn’t learned fractions yet so all I could say was “the distance around a circle is a little bit more than three times the diameter.” Well actually I didn’t know the word diameter yet so it was “A little bit more than three times across the circle.”

I always thought he used geometry and trig to get a precise number....he used a 6-sided hexagon inside a circle worked out the circumference of that, then made it into a 12-sided shape and got the circumference, made _that_ into a 24-sided etc etc until he'd made a 96 sided shape and was able to figure out pi to about 10 digits. Good effort though, certainly at the conceptual level of probably most people.

Mr. Rayner: You did a great job on the arts and crafts. It would make for a neat after-school project. But you only guessed the .14 part of pi. Maybe guesstimate is a better word. You took the idea that we already know that pi is 3.14, and you drew a model that showed where the .14 would fall. But never do you say how the exact .14 is calculated. If I were guessing like you did, and I used you "halves" method to go from 3.5 to 3.25, I would have put pi at 3.125.after all, any dullard of a mathematician in Archimedes' day could have told you that pi was between 3.125 and 3.25. Because of this, you have done Archimedes a huge disservice. After all, he did not draw out a wheel and a road and measure it. He used the method of exhaustion to predict the upper and lower limits of pi by finding the areas of polygons inscribed and circumscribed about a circle. He continued dividing these polygons until he had polygons inside and outside the circle with 96 sides. He thus set the limits of pi as 3.140845 < π < 3.1428571. I like fun and games as much as the next guy. But you did say that Archimedes was a genius for his discovery and then took the conversation to the level of a third grader. Not cool.
