tug of war for Io is like bending a paperclip back and forwards

Categories: Comparisons

An example of an analogy used in public science discourse:

"The largest active volcano on Io is twice as big as Texas, and the reason it is this hot is because one side of Io is very close to Jupiter and the other side you have got the other satellites pulling. It is like bending a paperclip back and forwards, you get a lot of heat generated. And that is what is happening on Io. It's being this tug of war which generates all this heat and all this volcanism."

Dr Paul Abel (Lecturer in Theoretical Physics, University of Leicester) was talking on an episode ('Saturn v Jupiter') of The Infinite Monkey Cage.
