This is all very timely as my eldest daughter has just started doing functions of complex variables in her final year of high school. It’s been fun to brush up on this stuff so I can help her with her homework questions.

Apart from Ahlfors “Complex Analysis”, this was about as good as it got for images of complex functions.

Sadly, Tristan Needham’s “Visual Complex Analysis” didn’t come out until several years after I finished my degree.

This is a truly wonderful video by 3blue1brown that motivates a beautifully presented introduction to conformal maps by way of Escher’s “Print Gallery”: https://youtu.be/ldxFjLJ3rVY

I studied complex in my honours year in pure maths and it took me weeks of study to build up the kind of intuition for complex maps that Grant lays out in 45 minutes with gorgeously crafted visuals and animations. So inspiring.

This picture broke my brain

Deadloch season 2 is more than living up to expectations so far. So funny.

The current and projected impact of AI and formalization on the practice of mathematics is analogous to the impact that the automobile had on the evolution of cities.

Before the introduction of the automobile, city streets were narrow and optimized for humans, horses, and carriages. When cars, buses, and trams were introduced, they were undoubtedly faster and more powerful than any prior form of transport; but they would clog the roads and crowd out pedestrians.

Over time, new roads, railways, and freeways were built for the exclusive use of mechanized vehicles, enabling rapid and efficient long-distance travel; but this came at the cost of urban sprawl, the degradation or destruction of once-walkable communities, traffic congestion, and significant environmental impacts.

It was only belatedly realized that to resolve these problems, it was not sufficient to simply make automobiles faster, more powerful, or more energy efficient, or to bulldoze all the old roads and networks to make way for new ones. Thoughtful urban planning, as well as the development of social and legal rules on how to manage traffic, were necessary to allow both pedestrian and automotive transport to co-exist in a manner that retained the benefits of both.

Right leg is feeling sore so to give it a rest I switched my usual 5km run for a 1km pool swim today.

It’s my first swim in ages, maybe six months or more. Definitely feels harder than running for me even though it doesn’t push my heart rate up as much. Probably good for all my desk-inflicted shoulder and neck tightness though.

This afternoon’s listening.
