Can the knees go over the toes? (2016)
Just last week, I was guest lecturing to a class of physical therapy students at the University of Missouri. I asked a simple question, “How many people here think we should never have our knees go…

The Ferocious Complexity of the Cell
Fifty years ago, the first molecular dynamics papers allowed scientists to exhaustively simulate systems with a few dozen atoms for picoseconds. Today, due to tremendous gains in computational capability from Moore’s law, and due to significant gains in algorithmic sophisticiation from fifty years of research, modern…

Pascal's Apology, or why computer science is complicated
Blaise Pascal once famously ended a letter with an apology : I'm sorry that this was such a long letter, but I didn't have time to write you a short one. Computer science has pretty much the same problem. It's a young field, and young fields are, by their nature, messy. As we race to generate new knowledge, we also…
