People seemed to engage with the material and there were quite a few questions at the end. The slides for the talk are available as a pdf or through the embedded widget below. My style for talks is heavily skewed towards minimalist slides with lots of verbal explanation so without having me beside you to guide you through them they might be hard to understand. https://www.ianhuston.net/2009/07/numerical-calculation-of-second-order-perturbations/ Thu, 23 Jul 2009 16:30:43 +0100 https://www.ianhuston.net/2009/07/numerical-calculation-of-second-order-perturbations/ My new paper, written with Karim Malik, has just been released into the wild. We show that it is possible to numerically simulate second order perturbations for a single scalar field with a canonical action. I’ve been working on this for a long time and learned a lot about the mechanics of inflation in the process. I’ve also churned out quite a lot of python code, and learned some rudimentary parallel programming.
