the kinetic energy mentioned is the kinetic energy of the internal generating conductors moving through an exciting magnetic field inside the dynamo
I contemplated on this one since last time a friend wanted to know how much wind power needed to charge a 12-volt lead- acid battery using a mini wind power he has just set-up in his coastal residence he has observed that the propeller would rotate freely without the battery connected to his system but when connected back to the setup, the propeller would rotate so slowly almost stopping.
Why it would require greater applied mechanical force to rotate an electric dynamo when electric power is being supplied to an external resistance load than rotating the dynamo without the load - the change of kinetic energy per unit time is diminished in the presence of electric power supplied to the external load so that the internal generating conductors inside the dynamo cannot move faster than without the load. to barely rotate the dynamo without rotational acceleration what is needed at least is applied mechanical power equals the electric power needed in the load.

"... we lose" that's scary for the lack of scarier word

(i like this part since there seems to be a kind of feedback and control system in a biological setup and what happens when this feedback and control system is upset? and how we have upset already the feedback and control system of the planet the mechanism that regulates global temperature anyway, i have watched the premier showing of the hbo production, i waited for it as it was advertised then)

The fungus proliferates when there is a large supply of hosts—for instance, when the ant population flourishes and becomes so large it threatens to overwhelm the resources available to the colony. As more ants fall victim to zombifying spores, their numbers dwindle until (a) there are once again sufficient resources to support what remains of the colony, and (b) there are far fewer ants available to serve as hosts...

looking forward to spring training 2023 to start this Feb meanwhile, a refresher video

the lectures are compiled into videos

the interaction might be highly suppressed since the strength of such interaction is directly proportional to the mass of the fermions involved that are so light

so now, since it is an mwfsat day some things for qft and we have Notes from Prof. Sidney Coleman's Physics 253a: Quantum Field Theory, this is one of my main resource materials for self-refresher courses in qft

(just posting today, an mwfsat day, what has been done yesterday, a tthsun day), here, adhering to what is analogous to Kaluza's cylinder hypothesis

surfing the internet to look for good books and have stumbled on this one, just scanning few pages i can already say this is a good book, may come handy for pre-requisite refresher topics
Introduction to Differential Geometry
https://link.springer.com/book/10.1007/978-3-662-64340-2
well... i also study a 2D gravity, a (1+1)-dimensionally reduced version of GR, still a work in progress
https://foxtrotpaparomeo.wordpress.com/2022/12/05/rough-draft05122022static-solutions-to-einsteins-field-equations-in-11-space-time/
and in 1991 a 2D gravity was used by Strominger et al to study hawking radiation

in connection to mirror symmetry, in the 1980s the first superstring theory revolution happened, it was when in 1985 Strominger submitted a paper
New manifolds for superstring compactification
https://link.springer.com/article/10.1007/BF01216094
part of my academic plan this 2023, to take up an open course in mirror symmetry course session twice each week, 3-hr session so much of my time this year devoted less to socmed
