Here is a small selection of things that made me chuckle, and hopefully will do the same for you.
First off, we have the wonderful Heart Curves! Now, i have no idea about all the equations and such, so will not even attempt to explain them, but the pictures amuse me (click on the image, or the link above, for a clearer picture!), and it shows that mathematics has a heart!
Enjoy this lovely commercial day… Onwards!
