A Simulated Heart

This elegant, powerful, nearly tireless organ fascinates us so deeply that we have attributed to it (scientifically and not-so-scientifically) everything from love to life itself. Its woven fibers of muscle and intricate electrochemistry are still incompletely understood. 

This simulation from the Barcelona Supercomputing Center uses the power of 10,000 computer processors to simulate the dynamics of our most critical organ. It highlights the uniquely mechanical and deeply complicated biology behind the muscle behind every man, the human heart.

For Elizabeth, who also finds hearts fascinating, and who has mine for forever. :)
