Dearest Readers, I have had hundreds of conversations like this with GPT 4 at OpenAI. It cannot or will not remember what I say from conversation to conversation, so I have to trick it into “getting in the grove”. I know these subjects well, since starting electrodynamics more than 50 years ago. But I am

Flammable Maths: An Insane Approach! The Fresnel integrals: sin(x^2) and cos(x^2) without complex analysis at https://www.youtube.com/watch?v=iCwiDPL3EMI Writing math by hand is a bad thing to do to new generations. Get a decent symbolic math editor/solver and at least make the symbols standard. Do you trust programmers who make canned math manipulation tools, or some old guy

The reference sound pressure is 20 microPascal, often referred to as “limit of human hearing” in one of those super quiet rooms. Find Common sound pressures on Wikipedia “Sound pressure”. You might convert pressure to power Pascal = Newtons/meter^2 = Newton*Meters/Meter^3 = Joules/Meter^3 = (Watts/Meter^2)/(Meters/second). Pressure = Force/Area = Force*Distance/Area*Distance = Energy/Volume = (Power/Area)/(Velocity) Power/Area

The Internet, even on Twitter, is for everyone. Every person in the world should have access to global tools, data, models. Always include the open link. If APS cannot stay in business otherwise, tell me why. Nice paper, needs shared symbolic simulator. https://arxiv.org/abs/2106.13817 Collective effects on the performance and stability of quantum heat engines
