Rebellious Rhythms at the Heart of Nature

Rebellious Rhythms at the Heart of Nature

Physicists are using equations to reveal the hidden complexities of the human body.   From the beating of our hearts to the proper functioning of our brains, many systems in nature depend on collections of ‘oscillators’; perfectly-coordinated, rhythmic systems working together in flux, like the cardiac muscle cells in the heart. Unless they act together, [...]
