Taking the Mystery Out of Pi, 1/4
Loading...
Uploaded by MathFromTheGut on Dec 25, 2011
Fun introduction to Pi, proportions, estimation, and other concepts.
Princeton University Electrical Engineering graduate Eric Leonard emphasizes intuitive understanding (from the gut) over memorization.
BEWARE: THIS IS NOT YOUR USUAL MATH VIDEO!!! YOU WILL ACTUALLY LEARN THINGS IN WAYS THAT MAKE IT DIFFICULT TO FORGET!!
This first part of this video series introduces the concept of proportions with simple examples. If fully understood , it should be easier to follow the next parts of the video.
In the second part, we first estimate the circumference of a circle with a one foot diameter. We then use the concept of proportions developed earlier to extend this estimate to two larger circles.
Pi is introduced in the third part and is then used to obtain the circumferences exactly.
Finally, the student's learning is reinforced/tested in the fourth part with questions involving real world applications.
Enjoy!

Thank you. This is my first attempt at a math video and I'm trying to do something a bit different than what's out already out there. I appreciate all feedback.
