A Perfect Circle

What is a mathematically perfect circle and why doesn't it exist in our universe? Find out in this episode of Stuff to Blow Your Mind as Robert and Julie look high and low in a universe of imperfection.

Supernormal Stimuli

No longer limited by the constrains of their environment or biology, humans have remade their world. Why walk when you can soar? Why shout when you can whisper in the ear of a listener halfway round the world? And why limit yourself to normal stimuli when you can condense the sensory world into nuggets of superstimuli. Join Robert and Julie as they discuss junk food, gaming, pornography, the Internet and beauty itself all in the framework of natural biology.

Do perfect circles exist in our universe?
