I dimly recall a Daedalus DREADCO column which, starting from hydroponics, was exploring the limits of artificial vegetative growth, and came to the conclusion that under the right conditions, it was all a question of how much energy one was willing to pump in.

Maybe we need a fleet of satellites beaming formed microwaves down to our giant Cucurbitaceae?

(my wife kept prompting me to harvest my radishes this summer; by the time I actually got around to it, they'd grown to sizes ranging from a small potato to an entire fist)



Most impt itswise problem of our preneoceramic age is [how to sell] radiative cooling..

Unfortunately, being not on the convex hull (pareto front) of the funders (now or ever? But thanks Stanford for trying!) (that is, not amenable to dual usage..?)..


Yeah, I guess orbit (better yet: points further out on the ITN*?) must be pretty much like being in a giant Dewar...

Without using greek or latin: models where e&m charges dont alter the curvature of space are close approximations to the real thing.

Contemporary physicists call this a “constant coupling” https://physics.stackexchange.com/questions/3901/what-is-a-g...

This is not true for the strong force, but you wont get nonsense either if you zoom out far enough (coarse graining, right).

[So “perturbation theory works for SM”, but saying gravity is “non-renormalizable” gives the impression that Manuel Bronstein didnt already anticipate this before he was purged.]

mtw have a mnemonic “space tells matter how to move, matter tells space how to curve”. you arent allowed take short cut as in em “charges tell charges how to move”. Indeed (already true in SR) the fields themselves have mass, so short cuts blow up your face..

Otoh, if you try to take the proper path (integral) you run into the issue of nobody knowing how. Roughly, you need the intrinsic curvature for the integral but you need the integral for the intrinsic curvature..

Yep Percival knew what was up, but even at the phySE page above “algorithmic compression” was spoken. Gisin you linked had “Kolmogorov complexity”, no delvings?


poor (bedniy?) MPB's neighbourhood would eventually gentrify: https://www.youtube.com/watch?v=1ugivNRYfjc&t=214s

If one avoids the uv catastrophe by substituting a fixpoint, are there ever multiple possibilities? (in computer semantics we sometimes have entire lattices of fixpoints from which to choose)


there are other fixed points, but they are too benign to get attention. (Ir). and manifolds.
