How does the 🧠 process information?

In this review we show how to use the tools of non-equilibrium thermodynamics to understand brain dynamics in discrete and continuous state spaces

Great work led by Ramon as part of his PhD

The illusion of illusions: There are no optical corrections in the Parthenon One of the oldest and most enduring myths in human history is the belief that the Parthenon was cleverly designed with various curved structures and sizes in order to correct optical illusions, and th...

The illusion of illusions

One of the oldest myths in human history is that the Parthenon was cleverly built with curves so that it looks straight, to correct some visual illusions

In this paper I demonstrate that there are NO optical corrections in the Parthenon

That sinking feeling.

In our latest foray into the mathematics of the kitchen, Sam Howison is chained to the kitchen sink. Quite right.

Only another 170 or so episodes to go.

Network Models of Neurodegeneration: Bridging Neuronal Dynamics and Disease Progression Neurodegenerative diseases are characterized by the accumulation of misfolded proteins and widespread disruptions in brain function. Computational modeling has advanced our understanding of these proc...

This is a very nice paper that answers a simple question that we have been pondering for years: Can you represent the dynamics in regions connected by pipes by a much simpler network? Very important for toxic proteins in the brain.
The answer is yes, but you have to do it properly.

When we talk about mathematicians, we often try to show what they looked like.

Here is a short list of famous mathematicians/scientists with no known portrait (AFAIK):

Pythagoras (c. 570–495 BCE)
Zeno of Elea (c. 490–430 BCE)
Al-Khwarizmi (c. 780–850)
Nicole Oresme (c. 1320–1382)

Prof @alaingoriely.bsky.social* reveals how simple, optical & aural, geometric illusions can be modelled mathematically, shedding light on how we process information

Then we need to define the term naive. Naive reasoning may not show that gravity yields ellipses, but few would call them emergent—they're direct closed-form solutions. Turing patterns, though also analytically derived, are typically seen as emergent due to their unexpected, self-organizing nature.

In the second lecture we're showing from his History of Mathematics student course, Chris Hollings takes us into 19th century algebra when, instead of thinking about how to solve equations, people were beginning to ask which equations can be solved at all.

You've got friends round for coffee and cake. There are seven of you. Trouble is, you've made a square cake. How do you make sure everyone receives an equal share?

Nature hates sharp corners. It prefers curved edges and non-flat faces. Now mathematicians have cottoned on.

In this endearing 1923 caricature by his mother, 11-year-old Alan Turing gazes at daisies instead of playing hockey. Decades later, he’d explore phyllotaxis—the spiral patterns in plants—using a 'digital computer', in one of his final works, cut short by his untimely death in 1954.

Gábor Domokos is best known for the Gömböc. But he hasn't been resting on his mono-monostatic laurels. Together with colleagues including @alaingoriely.bsky.social he has discovered soft cells, nature's mathematics lesson.

🚨REVIEW
We have written a review on the emerging topic of nonequilibrium, irreversible dynamics in the brain.

Now out on the arXiv: arxiv.org/abs/2504.12188

We introduce the relevant mathematical frameworks, discuss recent interesting results, and look to the future of this research direction!
