just reminiscing those happy elementary athlete days with this ccr song, actually we sang this song on the way home from a meet, the entire school delegation cramped inside a copra howler truck owned by one of our baseball teammates... our coach enticed us to sing as the rain began to leak inside because the trapal covering had small ripped openings but nevermind since each of us players received his/her incentives ;) "much more money" as we used to joke

i took a hike this morning to try to close a small business agreement with someone re my customized electronic projects and happened to pass by the public elementary school and saw the status of the construction of the school's mini sports complex and quite delighted to see that the construction is nearing to its completion... i could only imagine that in the coming weeks i would be playing baseball in the school again to relive those elementary school years there when we were training in our team for various coming meets... those happy elementary athlete days and how we liked it to play under the rain!
not totally legwork since i ride a motorcycle in going some places of course scratching head most often especially during gas price hikes

regarding my daily schedules, 7 days in a week i divide into mwfsat and tthsun... mwfsat for refresher mathematics, qft and electronics customization design works, tthsun for general relativity/grav and refresher topics in electronics engineering and it's on mwfsat days i usually do legworking to meet people who are potential buyers ;)
the aslvs in the photo is my first version before i replaced the 30-amper relay with a 50-ampere mosfet

just rigged a new adjustable power supply (left) for my own personal use at the lab, the output dc voltage can be selected from 9 volts to 15.8 volts with 7-ampere maximum current output... this would be useful in testing my customized electronic products such as the automatic solar low voltage shutdown aslvs box (right): (on test without a load at its output) the aslvs in the ON mode with a dc supply voltage not less than 12.9 volts, aslvs switches to the OFF mode when supply voltage goes down to 10.8 volts
wormholes? you can start with understanding the geometry resulting from rewriting Schwarzschild metric in isotropic coordinates and do some digging regarding isometries that would involve the famous Einstein-Rosen bridge... some basic discussions you can find on pp. 24-26, Townsend. https://arxiv.org/abs/gr-qc/9707012... my concern here though is on conformal compactification pp. 40 but since today is an mwfsat day i can dwell on it tomorrow
and... anyway
congratulations! to Maldacena conjecture it's 25 years now since its pre-print submission in November 1997 still standing as a very useful tool
The Large N Limit of Superconformal Field Theories and Supergravity
https://arxiv.org/abs/hep-th/9711200
the main issue addressed in the ff. blog entry is "Physicists create a baby wormhole in the laboratory" but my particular interest is...
-------
(on Maldacena's conjecture)
There are quantum field theories (theories of gluons, quark-like particles, and some additional friends, but with no gravity, in a world with three space dimensions and one time dimension) that are exactly equivalent to supersymmetric string theory (a theory with nine space dimensions and one time dimension, with an infinite set of particles and fields, and with quantum gravity) where the strings are moving on a uniformly 9+1 dimensional curved space.

i've been reading Maldacena's conjecture since 2015 i think, maybe this time i'd be able to get some clues on what i am reading because i have a key now to decipher Maldacena's paper but there are pre-requisite subjects you know, seriously

just making an immediate follow up on/of what has been tooted last night with some corrections in the draft
https://foxtrotpaparomeo.wordpress.com/2022/12/05/rough-draft05122022static-solutions-to-einsteins-field-equations-in-11-space-time/
supposed to accomplish a legwork today for me to sell my customized units in electronics but it's raining so i have to postpone well a u2 for a while, i'm romanticizing being a member of the elite mounted troop of the bolshevik army the music video though is something about the Russian winter war i think but a proNATO would take a comparison of that war to the ongoing war in Ukraine as a Russian invasion well...

a typo in the tooted rough draft, possible corrections here while also checking where other errors are
this sunday had the time to continue this draft and be resuming no sooner than next sunday and here i tried to meet the compactification requirement in the spatial coordinate sense, carried it to the specific case

and this sci-fi movie back then were they already using quantum processors? Doug outsmarted the smartest people in the technical team able to discover that they were using an advanced technology kept secret from him at first

time to get some highly educational inputs from this article (as an aside i would like to point out that science in general and physics in particular are making such significant strides who knows in the future the seemingly fictional are indeed true

if i'm not mistaken in my recollection, there was this science program on bbc it was advertised along this song

(here's their paper, the words "learning techniques" must be emphasized to make clear of things)
----
Here we use learning techniques to construct a sparsified SYK model that we experimentally realize with 164 two-qubit gates on a nine-qubit circuit and observe the corresponding traversable wormhole dynamics.

(what they actually did in their experiment was basically computational [learning machine] using Google Sycamore processor "to construct a sparsified SYK model that we (they) experimentally realize with 164 two-qubit gates on a nine-qubit circuit and observe the corresponding traversable wormhole dynamics...", certainly did not create a real physical wormhole in the lab nevertheless, their study could be important as demonstration of how to study some highly speculative aspects in quantum gravity using highly approximate models i must also point out a bad science journalism in hyping that a real physical wormhole "has been created in a quantum chip! via the supposed observed teleportation" it is not the case as i understand no wormhole created)
