Unless I misread it, if a project is deemed to have an "FBA" then the project leader is an "FN", in the author's opinion. And yes, some such projects have been explicitly called out.

Nothing like personal attacks to get your point across. Well done author.

The standard and most effective form of curation in science is the reference list at the end of a paper.

But usually you just read everything that is relevant to your research interests from the daily arxiv posting.

"You can upload your research and publish it on the open web. Members of the community will be able to vote on your research to raise its visibility."

Oh dear.

Are you sure it was peer reviewed at all? It looks like a conference proceedings.

I think the article misses the point of what physics is. It is not a collection of "sparse" models and principles, rather, it is a scientific discipline from which such models have emerged.

You will notice the article conflates the two things: physics and the known laws of physics (e.g. first para in section 1.2). Simplicity of the latter does not imply simplicity of the former, but the article assumes that it does in order to tackle/state the question as posed: "Why is AI hard and physics simple?".

The author is talking about how a given physics model appears simple when they are presented with it, e.g. a particular quantum field theory. This is the kind of limited perspective about research that an undergraduate physicist may develop simply by solving the hand crafted problems that are presented to them.

However, the true difficulty in physics is arriving at that model in the first place. Decades of work offered up against experiment, the associated conceptual leaps in understanding required to get to e.g. a quantum field theory which succesfully predicts things are nothing short of a monumental achievement. To say that physics is simple is ludicrous.

"The counterfactuals that matter to science and physics, and that have so far been neglected, are facts about what could or could not be made to happen to physical systems; about what is possible or impossible."

On the contrary, if I had to describe theoretical physics in a nutshell, I would say it is entirely about what is impossible. Pick any physical law or theorem. I cannot exceed the speed of light. I cannot globally decrease entropy. I cannot measure a force between two static electric charges in vacuum that deviates from the Coulomb force law.

Note that if f(x) = x^2 then the second derivative f''(x) = 2, so it looks like you're off by a factor of 2 (as well as the accuracy issue).

Knowledge of complex numbers are required to solve quadratics too (when the discriminant is negative).

If you liked Primer, the film "Timecrimes" does an excellent job at the physical consistency of time travel.

It is interesting that they chose to use a first person shooter as an example screenshot since gameplay would be broken by visual changes in occlusion.
