The infinite life of pi - Reynaldo Lopes | Calculating Pi with Real Pies |
The ratio of a circle's circumference to its diameter is always the same: 3.14159... and on and on (literally!) forever. This irrational number, pi, has an infinite number of digits, so we'll never figure out its exact value no matter how close we seem to get. Reynaldo Lopes explains pi's vast applications to the study of music, financial models, and even the density of the universe.

It really makes me laugh that this is called pi. ALthough, now that I'm thinking of it, pi probably came before pie. I never knew what pi was exactly, so the lesson today really helped me understand. Although in the centers today I don't think my group and I did it right.

I also think it is funny and clever what the guy did. Measuring pi with pie is smart, but I wonder how much it costed. I also wonder what they did with all the pie!

WOW... I can't believe that this guy actually calculated and got the number close to pi with real baked pies. Who would have thought of that? I really like how this person actually planned things out and was so smart. I really like this video a lot.

I watched the first video and I learned that pi may have been used to make the Egyptian pyramids. Also, is it just me or have computers suddenly become 300 IQ level? I mean 2 QUADRILLION DIGITS OF PI, 2 Quadrillion! I mean the human record is 67,890 digits, which is still insane, but it's not 2 quadrillion this video taught us about pi and computers.

It is crazy how people are so smart to actually figure this out. In the second video, that guy bought so many pies and made a big circle and if he finds the circumference and diameter, he can divide that and hopefully get at least close to pie. Pie=3.14. So when he divided it, the numbers would last forever but it was rounded up to 3.14. So he technically did it. It is so weird saying that he found pie by using pie. I also wonder what he did to all of those pies.

I really like the second video because it is really fun to watch a man calculating 3.14 which is pi with really baked pies.

This is very cool and very tasty. I know that Pie=3.14. This guy got pies to try to get pie. He will find the circumference of the pie and the diameter of the pie. Then he will divid the answer he got for circumference and the diameter and get a number that will never end. With all of those numbers, if you round it up, it will be 3.14 which is pi. This is so weird to think that you are trying to find pie using pie.

I think that the 'concept' of pi is really cool, because I've seen many competitions of people trying to see how many digits of pi they could list, and it always amazed me how many numbers people could list, and it was even more crazy to me that someone could memorize that many digits in the right order, especially because there is no actual pattern the numbers are in. I didn't actually know the numbers in the digit "pi" were infinite, and that they went on forever so this video helped me learn a lot about pi too!

I think that everything about pi is really cool and fascinating, because I never actually knew that the numbers of pi went on forever, and I just fine that really cool. I have seen many competitions of people who tried to list as many digits of pi as they could, and it always amazed me that humans could remember things that well, and now with the information from this video, it is even more amazing, because there is no actual pattern to the numbers of pi, so people just somehow remember that much.

I think that everything about pi it really cool, because I've seen many competitions where people try and list as many digits of pi as they can, and the person who lists the most wins, and it always amazed me how people could remember so many digits of something I knew absolutely nothing about, that seemed so complicated, and with the knowledge that this video gave to me about oi, it seems SO much more impressive about those competitions, because I never knew that the numbers of pi went on on forever, and that there was no set pattern to them, so you just had to remember all of these seemingly completely random numbers in the right order.

I think that the whole 'concept' of pi is really fascinating, because I thought that the numbers have a set pattern, and that at some point they stop, but this video showed me otherwise! I never knew that the numbers of pi went on forever, and that there is no set of patterns that the numbers follow. I have seen a lot of competitions of people listing as many numbers in pi as they could memorize, and it always amazed me about how humans could memorize that many numbers, and with what I learned from this video, it make those competitions and/or challenges so much more impressive, because not only do the numbers go on FOREVER, there is also no pattern! That means that people just have to completely memorize 'random' digits in the perfect order, and I really don't see how someone could even memorize 100, much less about 70 THOUSAND (the current world record.... WHAT?!).

I think the concept of pi is really fascinating. A number that never ends? I thought there must be some end to it, but there isn’t. I managed to memorize some of the digits. I can go up to 3.141592653589793, and I keep trying to memorize more, digit by digit.

Note: the second video is 3:14 seconds long.
