Tales from the ArXiv: Rodents in Hyperbolic Spaces

This morning, I noticed the new paper Can Rodents Conceive Hyperbolic Spaces? With a title like that, clearly the paper deserved a closer look.

The abstract also includes a great line: We show that, according to self-organizing models, if raised in a non-Euclidean hyperbolic cage rats should be able to form hyperbolic grids.

I know I have obvious biases as a mathematician, but the idea in the paper seems really cool to me.

Mice on Lake

I have noticed in the last couple days that a lot of mice have taken up residence in the greenery in front of the "Shops on Lake" sign. While passing that, one can see numerous mice scurrying back and forth across the sidewalk in that area. It's pretty amusing, though I imagine the city will be doing something about this soon.
