Some of the exhibits were the same ones I remembered from the past but many were brand new to me. Of course, my favorites, pictured above, were mathematics. Years ago, this part of the exhibit did not exist. I may have to break down and take a class trip here. The things I saw were just too good not to share.
My favorite exhibit wasn't in the mathematics part, but in a part of the Hall and it was all about networks. I taught a course in the community college on networks and it was really cool seeing all the applications, including ant farms, dance floors and phone connections. It would be nice to share real life math with my students.
Calculus --This is an example of the model Archimedes used over 200 years ago to show that the volume of a cylinder is equal to the volume of a sphere and a cone. He did it by using slices, one of the ways we find volume in calculus.
This one you have to see to appreciate.
A great example as to why every operation is not commutative.
