Many physicists from the most prestigious institutions, whose papers are the most cited, do the same with biology. As a result, we have a flood of grants going to theories based on the erroneous premise that living beings "become more complex", or that life is "optimizing something," among others.

It’s really sad to see bright physicists playing with ideas they don’t actually understand (it seems a pattern among theoretical physicists and many philosophers). Too many aficionados seem eager to have an opinion. Study neuroscience and then talk.

Using hypergraphs for your data? Believing that hypergraphs “generalize” standard graphs to “higher order” structures? Maybe you are conflating structure with mechanism, and this podcast is for you! 🎧 Spotify: creators.spotify.com/pod/show/com... 🎧 Apple: podcasts.apple.com/us/podcast/c...

Maybe it’s time we stop calling graphs “pairwise”. Multivariate coupling functions include HO interactions by design, hyperedges are optional. Under the order-decomposability assumption, the same node-level dynamics can be written as infinitely many equivalent multilayer (“gauge”) models. 1/

In complex systems, linear tools fail against nonlinear phenomena. You can’t fight smoke with a sword, nor bite water with your teeth—because complexity dissolves brute force. It demands sensitivity, adaptability, and systemic understanding. #complexity
