@johncarlosbaez Additionally, players of instruments often have their own vocal language for the sounds/notes their instrument can play. Here is an example of the Tabla (a percussion instrument!!) At various points the player will vocally sing what he plays before or while playing.

@johncarlosbaez The most popular traditional music in Pakistan is the same as in Northern India. For the scale we use the vocal sounds

@interfluidity unfortunately, it's on the todo list of my website for several years.

Read a fascinating idea today, that universities must separate their legislative, executive and judicial functions, same as country governments do. Since, politics has permeated all aspects of universities, this might help to contain the bad effect.

I wonder what other publicly valuable institutions should also follow the same schematic.

The Remaining Carbon Budget for 50% chance of 2C warming is 1200GtCO2. https://www.nature.com/articles/s41558-023-01848-5

Doing a naive calc: 1200e9/8e9 world pop/50 years of your remaining life = 3 tCO2/year.

Driving 20km/day will set you back 1.2tCO2 of that.

@tao Do you have any chatgpt custom instructions for this conversation?

@julesh @johncarlosbaez The degree of guilt or punishment often depends on whether you intended to harm or not. This can be difficult for the prosecution to prove, so often lots of room for back and forth.

@interfluidity I use the tongue-in-cheek "oh, evolution".

@ColinTheMathmo I would say "One repeated solution". Later on they study second order ordinary differential equations with constant coefficients. There the "One repeated solution" case of the characteristic equation does yield two solutions of the ODE. So the repetition here matters.

@interfluidity This serves as my reminder to do my annual read of The Tyranny of Structurelessness.

@TaliaRinger I usually give out prizes for catching my mistakes - some of which are delibrate. Really helps with student engagement sometimes.

@ddrake How were you taught? The article follows the standard way tensor products are introduced to Physicists in Quantum Mechanics 1 course. Sometimes, a bit more abstractly with their properties as axioms, but then immediately jumping to this discussion so it's not confusing.

David Deutsch (paraphrasing): There is a distinction between experiments, demonstration and measurements.

Experiments are done to test rival theories (at least 2). At the end of the experiment, your doubt in each theory must change from before.

Demonstration: just show that the predictions of a theory are indeed born out in practice.

Measurement: determine the value of a parameter in a single theory.

He says that the latter two are often confused for the first.

@gregeganSF What are the ergonomics of reading a math book laid out on a desk in front of you, basically at the same height as a laptop keyboard?

The mathematical "reason" is that at low energies all potentials are linear or quadratic, or the inverse square of planetary motion.

But that doesn't explain why at a very wide variety of length scales, all human-sense-observable phenomena settled down to such energies.

A curious fact about Newtonian Mechanics: It explains and accurately models pretty much all mechanical motion observable by unaided human senses. But soon as you build some sophisticated experimental appratus it breaks down. eg. Mercury precession or double slit.

@smari Thank you. I am glad you recommended a recent book, which are usually aware of the impacts of modern high-technology on the feasibility of political and economic theories.
