Those who have token money will succeed. It biases maths and theoretical physics towards the rich. That one thing that was free.

As a musician with a modular synth, I have three boxes, two just for audio. Somehow, after decades of careful curation, the cable I need is always missing!

PS2: AdS/CFT (and we have at least one good candidate since Maldacena in string theory) correspondence shows that strongly coupled quantum systems in d dimensions are dual to *classical* gr systems in d+1 dimensions. Somewhere somehow

Ps: your comment on dissipation is good. But in certain frames GR can reproduce that. I’m far from an expert, but definition of energy is rly hard in GR (need both Noether thms). Research on the topic seems to have stalled a decade ago. Pro

sorry for the late answer.. yes you can : https://arxiv.org/abs/1211.1983 but you might need to understand it in the context of holography in some frame you can recover non-relativistic symmetries, we got a paper on th

It’s pretty crazy what dynamics you get from NS.. until one realise they emerge from a tiny part of the solution space of Einstein equations.. which themselves emerge at the low energy limit of sth much bigger.

Per IPCC AR6 total power goes from 18TW to 16TW in a good scenario, due to increased efficiency (no Carnot cycle). Degrowth per IPCC / earth system scientists mean the 10% the richest consuming less power. It’s much more a wealth distr

He does says (said) a lot of stupid things, but also has a good analysis in some domains. He’s very influenced by meadows/ world3/ club de Rome and while it’s a toy model it certainly a good thing to have a global view.

While I have a massive collection of VSTs I always end up using my very limited modular and Rytm mk1. And Elektron machines are an UI nightmare.

Yes. I read somewhere that 90% of human never took a plane.

Psychedelics are several orders of magnitude stronger on the plasticity front. In therapy as well.

The contributed proposition by the 10 year old kid to make fossil fuel companies pay for solar panels is perhaps the best policy proposal I’ve ever seen. The second one is to make water companies CEOs swim in the Thames. That is a program.

There are some vendors that have a good variety of IMX sensors boards. Usually labelled Board Level MIPI camera, some with usable v4l drivers.

I just love long rail trips, often do Switzerland-Tunis via Palermo to see my in law family. Best trip ever was Tbilisi-Zurich via Batumi, ferry to Odessa Kyiv and Vienna.

Adaptation is not an alternative for mitigation. We have to do adaptation AND mitigation (drastic reduction of emissions). We can stop CC, science is very clear on this.

I have worked half of my life in both fundamental and applied science, I know how this work. In particular you can refuse jobs you deem unethical. Why not funding energy transition research for instance. It’s know to science for half a cent

Oh yes, they had some of the best climate scientists back then. It’s somewhat a scale up of what the tobacco industry did, same strategies, etc

When I was doing my phd, around 2 decades ago, I was often going to the library’s compactus to fish for a Phys Rev from the 80s. Back then papers were sparse and expensive. But the quality! The Higgs boson is 3 papers, 6 authors and 6 pages

It’s how gauge theories work: - fermions (charges) are in the fundamental representation of the gauge group, here SU(3) so 3 Colors - bosons are in the adjoint représentation, for SU(3) that 8 dimensions

agreed, when you start needing the the hodge star, diff form loose quite a lot of their interest. i'd add it's quite nice in string theories for RR fields and coupling to D-branes, where writing 10 anti-symmetrized indices quickly

from a theoretical physicist point of view, i find GA don't add much to the standard tooling ppl use, i.e. Lie algebras, Clifford and (sometimes) differential forms. while it's always nice to have a formalism that "hides indi

Well congratulations, you just stated the equivalence principle that led Einstein to GR (you need special relativity and a bit of maths and you’re there)!

I’m doing a bit of BREP for GIS and even in 2D with line segments only the problem is really non-trivial, a lot of edge (pun intended) cases to take care of. Type system helps enormously, so probably rust will be a win here (I think I saw a

The beauty and power of the Noether Theorem is what pushed me to theoretical physics. I consider it one of mankind’s greatest achievement.
