Everyone intuitively knows that facts change. But just as a half-life in radioactive decay implies a systematic degradation that is predictable and understandable, there are also patterns and regularities to how facts change over time. I explore the mathematics and science behind how knowledge grows and is overturned over time. Lastly, I explore the future of knowledge and its implications.
