The Power of Spring

Trying to describe what a spring is was probably one of the hardest parts of this book for me actually. I mean, there is a platonic ideal spring in my head which is like the coiled metal thing and you press down on it and it bounces back up. But fundamentally, and I never heard this described before until I read your book is that a spring is this device for storing energy and being released when we need it to. So yeah, it kind of broke my brain as well.
