Who are some underappreciated (both dead and living) physicists or mathematicians in popular science? Why do you think they deserve more recognition?

A 1d array of Quantum dots should just be called a Bloch-chain

@NTNUNaturalSci planlegger å legge ned flere realfagsprogrammer, inkludert mitt tidligere studieprogram i fysikk. Det tror jeg vil være tap for alle parter

it's due time I posted some physics again :)
This time: A formula for predicting the time dependence of a quantum observable in a system where the ground state is known, but where the system is subject to a small (time dependent) perturbation, making an exact solution infeasible

Way too long since my previous slide. Here is a _very_ crude slide with the kind of things one can stumble upon when working with Luttinger Liquids.
It turns out that reducing a problem to one dimension is not a simple task when the system is that of many interacting fermions

Ble spesielt fascinert av denne: At den klarer å "skjønne " at tiger-hendene faktisk kan dekke deler av yin-yang logoen -- at modellen har en viss sans for orientering av objekter og romlig forståelse

The AI lab DeepMind, which is owned by Alphabet, has released predictions for the shapes of nearly every protein known to science. Now, it has added more than 200 million predictions to an online database freely available to scientists across the globe. https://t.co/NWb6PFd0Fl
