Our new article in Chaos. One of my favorite articles so far. Connecting different disciplines and building on recent breakthroughs in ancient fields (Linear Algebra!).

How individual systems and their connections react to each other to ensure stability of the whole.
We live in a complex world with a plethora of connections and interactions. Many important processes, such as power grid dynamics, ecological interactions, opinion formation, or brain plasticity, can ...

We have released new, heavily reworked versions of NetworkDynamics.jl and PowerDynamics.jl for simulating dynamical systems on networks, and power grids specifically.

As the hydrogen bubble deflates, what are the alternatives? We present a "minimal methanol economy": using methanol as a gap-filler for the few sectors electrification can't reach.

New working paper together with Philipp Glaum, @fneum.bsky.social, @millinger.bsky.social:

OK, this is wild.

In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.

It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.

What the HELL?
