You've probably heard it mentioned out of the corner of your ear. Mathematical Modelling. What does it look like, how does it work, where would you even start? And why is a Dublin mathematician modelling the results of electrical currents in human brains? (Donated, don't worry)With Aine Byrne @ainebyrnemaths, Assistant Professor at the Department of Maths and Statistics in UCD and (briefly at the start) 5 year old Ruby with her own model of how the brain works. And me, hoping to learn from both. Comments, suggestions, criticism -take it handy though-  to @colmoregan @functionroompod on twitter.
