Mark gets mathematical with bayesian mathematician Sophie Carr.


Sophie describes herself as an “accidental mathematician”, getting into the subject after studying to be an engineer. She got her PhD on the job, and transitioned from fluid mechanics to Bayesian statistics.


Here’s the piping speech from Patriot Mark mentioned.
