What can I do with Maths? From Neuroscience to Wind Energy: 06/10/2021

Dr Emma Coutts talks about using her ‘mathematical tool kit’ to tackle problems in neuroscience such as how do neurons process signals? And how maths is used in the development of wind farms from site assessment to optimisation of wind farm operation – Watch here.

What is a Teaching Specialist?: 03/11/2021

Dr Tom Wong talks describes the role of a teaching specialist and why having teaching specialists is so important. Find out how someone ‘levels-up’ their teaching game with hints and tips from his own teaching experience. Watch here.

Mathematical Models for Climate Change – Tipping Points in Desert Ecosystems: 17/11/2021

Prof Jonathan Sherratt explains: The natural world abounds with spatial patterns, and the very largest of these occur when an entire ecosystem is patterned. Examples include banded vegetation in sub-Saharan Africa, striped mussel beds in the Wadden Sea, ribbon forests in North American this talk I will review some of these patterns and discuss the way in which mathematical models are being used to understand the underlying mechanisms and to assess their vulnerability to climate change.  Watch here.

From Interpolation to Machine Learning for UQ and Volcanic Eruptions: 26/01/2022

Prof Gabriel Lord from Radboud University explains how numerical techniques can help in uncertainty quantification and how they can speed up computations in the prediction of smoke plume trajectories from volcanic eruptions; timely predications are important for air traffic control. This is work is in collaboration with some of the British Geological Survey Team based at Heriot Watt. – Watch here.

Spectral Networks and Quantum Field Theory: 16/02/2022

This talk will feature a mix of geometry, topology and physics. I will start with introducing the concept of a spectral network. Aside from lots of cool pictures/videos, I will explain why these networks are relevant in mathematics, and how they encode particles in a four-dimensional quantum field theory! – Watch here.
