Probably, Approximately Correct: Nature's Algorithms for Learning and Prospering in a Complex World

How does life prosper in a complex and erratic world? While we know that nature follows patterns ââ,¬â€œ such as the law of gravity ââ,¬â€œ our everyday lives are beyond what known science can predict. We nevertheless muddle through even in the absence of theories of how to act. But how do we do i...
