Numericati

I'm a postdoctoral researcher in numerical mathematics and fluid dynamics, and I make videos about the things that fascinate me in my work.

The universe is continuous, but our computers are discrete. Between the perfect formulas of physics and the digital grids of a supercomputer lies a gap. Numerical mathematics lives in that gap and I spend my time there. We chop continuous space into grids, continuous time into steps, and hope that what survives the translation is still true.

Numericati explores the mathematics behind simulation: how we translate the laws of nature into the logic of a machine, and what we inevitably lose (or gain) in the process.

These videos are for anyone who is curious about how the world is modelled. No specialist knowledge required, but some love of mathematics helps.
