what is High Physics? Highphysics

High Physics primarily refers to Quantum Mechanics and General Relativity.

Special Relativity is undoubtedly important, but can generally be understood outside the context of High Physics.

🔥 if you made a sufficiently-accurate model of the universe, and had sufficiently-targeted functions, and sufficiently-optimized point-calculations, you should be able to see the future using math.⚔️ well, actually, ... you can. but the universe tends to fight back.

my common line is Quantum Computing is Fake. My understanding of the Uncertainty Principle doesn't allow for the type of non-trivial computing that is promised.

Also, it is in-disputed that Quantum Computers today do no non-trivial computing. Some "Quantum Annealers" do non-trivial computing, but there is a meaningful distinction of terms here. ⚙️ In general, if someone says All A are X, and a counterexample is provided of B are A; B is X; therefore not all A are X, one must make sure there is no sleight-of-hand in the definition of B.

Quarks are fake.

It is the rejection of the axiom the atom is made of protons, neutrons, and electrons -- each indivisible.

Maybe they do exist. So what?

So what are High Physics? We provide samples.

Low Physics - the Six Simple Machines.

Medium Physics - electromagnetism.

🔥 I have not recently had a channel to the effect of interesting interpretations of physics.

Core Thesis: Black hole "interiors" are not regions beyond an event horizon, but rather zones of extreme time dilation where matter asymptotically approaches ever-smaller horizons while experiencing increasingly severe temporal deceleration relative to the external universe.

Key Features:

# No True Interior: What we conventionally call the "interior" is reinterpreted as matter in various stages of approach to a receding horizon, with each layer experiencing different degrees of time dilation. 💡 There is confusion possible here regarding an inability to visualize 4-dimensional shapes. If you overlay a Minkowski spacetime over the area of a blackhole, every point within a radius will be "within" the cone.

# Temporal Stratification: Earlier infalling matter approaches smaller radii but never crosses a definitive boundary. Instead, it forms temporal "layers" - older matter closer to rs, newer matter further out, all frozen at different stages of approach.

# Finite Interior Time: While external observers experience infinite time, the cumulative proper time experienced by any piece of infalling matter converges to a finite value - creating the "temporal cone" structure.

# Observer-Centric Reality: The model privileges the external observer's perspective as physically meaningful, not just as a coordinate choice. The fact that external observers never see horizon crossing is taken as indicative of physical reality.

Philosophical Implications:

This model suggests that black holes are not regions of spacetime hidden behind event horizons, but rather:

* Temporal fossils: Regions where time effectively stops flowing

* Asymptotic structures: Where approach to a boundary is eternal

* Information preservers: Since matter never truly disappears behind a horizon, information remains technically accessible (though practically frozen)

This interpretation sidesteps many paradoxes associated with traditional black hole interiors while remaining mathematically consistent with GR's predictions for external observers.

Addressing Common Objections

The Coordinate Transformation Argument: Critics often argue that the inability to see matter cross the event horizon is merely a coordinate artifact that can be eliminated by using Kruskal-Szekeres or similar coordinates. However, this objection misses a crucial point: coordinate transformations cannot change physical observables. No distant observer, using any coordinate system, will ever receive a light signal from an event at or beyond the horizon. The mathematical convenience of coordinates that extend across the horizon doesn't negate the physical reality that external observers experience. The temporal cone model takes the position that what cannot be observed by any external observer in finite time should not be considered physically realized.

The Infalling Observer Perspective: Another common objection is that infalling observers experience crossing the horizon in finite proper time, making the interior "real" from their perspective. The temporal cone model provides a crucial insight here: the infalling observer experiences only a finite amount of proper time t_interior(∞) = 2√(2ε₀) × τ before the external universe reaches infinite age. This finite time is insufficient to reach any putative singularity. If we extend the infalling observer's worldline beyond this point (when external time = ∞), we're entering a regime that is mathematically similar to extending beyond t = ∞ itself - it may be formally possible in certain coordinate systems, but lacks physical meaning. The "singularity" that appears in coordinate extensions is thus no more physical than events at t > ∞.

The Singularity Problem: Traditional GR predicts a singularity inside black holes where matter is crushed to infinite density. Critics might ask: if there's no interior, what happens to the singularity? The temporal cone model reveals that this question assumes something that never occurs: matter reaching the singularity while the external universe still exists at finite time. Since infalling matter experiences only finite proper time before external time reaches infinity, the singularity exists only in the same abstract mathematical sense that "events after infinite time" exist - as formal extensions of coordinates rather than physical occurrences. The model thus replaces the notion of a spatial singularity with a temporal boundary condition.

after 11 days, the standings are similarly visible as they were after day 5.

  • Ben Healy - in the breakaway ⚙️ a group of riders, not candidates to win the overall race, who go in front for one day, hoping to win the stage twice, and thus in front for GC. for a variety of reasons, the other teams like that somebody with no chance to win is temporarily in first
  • Tadej Pogacar - still the odds-on favorite for first
  • Remco Evenepoel - still the odds-on favorite for third
  • Jonas Vingegaard - still the odds-on favorite for second
  • Matteo Jorgenson - the favorite for fourth ⚙️ not the "odds-on" favorite; as I use the term here it probably means "at least 70% chances". Jorgenson is more likely than any other rider to get 4th, but isn't that strong a favorite.
  • Kevin Vauquelin
  • Oscar Onley
  • Florian Lipowitz
  • Primoz Roglic

Joao Almeida (7th after day 5) withdrew from the race after a crash. But, the 8 riders here other than Ben Healy could still be the top 8. ⚔️ well, actually, maybe Ben Healy can stay in the top 8 💡 pundits say Vauquelin is most likely to drop behind other riders. 💭 Mathieu Van der Poel is now in 29th, which is about right The next 4 riders ⚙️ Tobias Johannesson, Felix Gall, Carlos Rodriguez, Enric Mas are also strong candidates for the top 8.

----

Tomorrow is the Hautacam stage. The first high-mountain stage; a 13.5km @7.8% climb. Team tactics will hardly matter. 💡 it is almost certain that Visma LAB will try to use team tactics to attack Pogacar, it is also almost certain that it won't matter

And, Friday is a mountain time-trial.

Barring injury, the GC should be almost set after those two stages.

yesterday was mostly unexciting tasks, such as:

  • the "journey stats"/"exposure stats" are now called "activity stats"
  • audio player cleanup
  • "multi word listening" cleanup
  • API server refactor
  • all unit tests pass

The most exciting new feature was "Daily Stats". 💡 the "give a star when you hit 100/250/500 questions" isn't enabled yet

----

also, I have been reading about https://expo.dev , which promises to be the easiest way to "convert your React web app into a mobile app".

Claude says it would take 2-3 weeks to do this migration. I'm willing to give it 3 hours today + all day tomorrow. 💡 maybe a few extra hours if it can also convert to "TypeScript".

regarding the last feature list:

a few simple fixes are done. ⚙️ have a way of showing/counting the available words not yet "exposed" in Journey Mode, a more-linear path through the lessons, improved "You're doing great" interstitials

the "per-day stats" failed miserably on the first attempt. the second attempt will be entirely server-based. but that is dependent on a few other changes.

a new mode was added: listen to 4 words, click them 🔥 in order; although that isn't required yet. 💡 there is a balance between "does it work", "is it useful", and "does it motivate other people to use the app".

----

i am debating "additional languages" as a new feature.

every language 🔥 at this point has a few "special" features that need to be managed.

The app might need a new name, or multiple names. Also, the fact that I'm not sure how Trakaido is pronounced could be an issue. I assumed it would rhyme with Hokkaido, but others disagree ...

----

Another possible feature is educational minigames for 3rd graders, but in a foreign language. "Choose the animals!" 💡 or, "how warm is dvidesimt degrees Celsius

----

Also, there might be an "enable experimental features" setting. 💡 because "optimizing the UI for some new features" isn't happening this week. But I need them, and other people are confused by them.

----

The other task probably not happening this week is "audio quality-control". I still don't have a lead for an LLM that will scan an audio-file and make sure it is the exact word, pronounced correctly, without any breathing noises etc.

Three of the Trakaido fixes are done: the hover issues, the multiple-choice answer count issues, and the 🔥 forgotten last dispatch, but also important improved word selection algorithm issues.

The word-lists are somewhat polished, but that hasn't been updated in prod yet.

The React re-draw bug is not fixed. I may need a smarter LLM to fix the bug; the ones I am using aren't finding it. 💡 the solution is probably to define a "canvas" area for the question, and redraw it completely for each question. This will require fixing the fact that the "question type" takes up an excessive amount of screen real-estate

💡 There is also a plan to re-generate the word lists entirely. But, a few key issues remain before I can run the "ask the LLM to regenerate data" step. For example: "are these two definitions of the same word?"

----

Additional "short" features, for tomorrow, include:

  • have a way of showing/counting the available words not yet "exposed" in Journey Mode.
  • have "Drill Mode" expose all words in a corpus if you do well enough
  • a more-linear path through the lessons. 💡 a full "tech tree" style path could be done. Duolingo got rid of that, for some reason.
  • make some of the "You're doing great" interstitials remind you about app features ⚙️ such as "don't type the text in parentheses" and grammar ⚙️ such as "Here is the pronoun table, with audio"
  • per-day stats: questions answered, words reviewed, words at each "level" of comprehension
  • track "last exposed" and "last correct answer"
  • an option to "always match pronoun" on two-word compounds like "He ate".

We live in a world that expects everyone to be specialized in politics. This is a worrisome thing. How can a democracy work when a majority of the people are disengaged from the national issues that drive voting?

Perhaps the answer is that it can't; a more staged system, where the people elect ward/city chiefs, and the chiefs vote on a candidate, might be better. 💡 but the flaw there is obvious; the same capture as the various political parties have had at their National Convention regarding the Presidential Candidate. ⚙️ it becomes polarized. 100 years ago, people could be selected for the convention before anyone knew the candidates for the Presidential nomination. Today, each faction selects the luminaries who will be required to vote for their candidate.

----

The idea of "governance by per-profession representatives" has its own flaws.

We can imagine a "House of Lords" style setup, with (say) 200 seats, 12 of which are for medical doctors. Initially, they may be selected based on their skill in medicine 🔥 and at getting elected. But, after the passage of time, they will be selected based on their loyalty to a faction. 💡 this is how Dr. Oz is in charge of Medicare.

----

I have not yet found any flaw in the "governance by per-birthyear representatives".

For example, on a STV system, all people born 1970-1975 select 8 representatives who are members of that cohort. With a provision for alternates should a member suffer untimely death, or (in the case of an inferior assembly) leave the jurisdiction.

The technical problems are addressable. No representation until the age of 10, "parental representation" (where the candidates are not members of the cohort, but parents of those members) until the age of 20. At the age of 70, they elect "permanent members"; no further elections, but no replacement on death.

Monango, North Dakota is a small rural town located in Dickey County, in the southeastern part of the state. With a population of under 50 residents, it's one of the least populous communities in North Dakota. The town is surrounded by wide stretches of farmland and prairie, reflecting its strong agricultural roots.

I have some more ambitious tasks for Trakaido planned. New modes, new languages, new webdomains, new spaced repetition algorithms. 🔥 I don't think of it as "spaced repetition". It is just "studying the material you don't know".

There is also "set up a pipeline to check audio file quality". Which is not ambitious as it is defined above, but it is perhaps equally difficult.

But, there is a short-term list for today:

  • Do one final "cleanse" of the wordlist
  • Re-enable the ability to have 6 or 8 multiple choice options available
  • Re-analyze the "audio" logic; on mobile devices there are some hover/selection-focus related issues causing audio truncation or double-plays.
  • Find the reason part of the screen isn't re-drawing properly after "New Word" activity in Journey Mode. ⚙️ all projects develop a lexicon. The "Mode" is the type of activity / question-selection algorithm, and the "Activity" is the individual question.

And, one additional question too complex for this, but still in-mind: how hard is it to convert this to a native app for iOS/Android? ⚙️ it would allow audio caching, and better on-device stats. But, it involves "interacting with the App Store". But also, could generate revenue.

The first time trial is over, and the GC standings are recognizable.

They have been recognizable throughout; with cross-winds on day 1 and attacks by Pogacar/Vingegaard.

  • Tadej Pogacar - the odds-on favorite.
  • Remco Evenepoel - the odds-on favorite for third place.
  • Kevin Vauquelin
  • Jonas Vingegaard - the odds-on favorite for second place
  • Matteo Jorgenson
  • Mathieu Van Der Poel
  • Joao Almeida
  • Primoz Roglic
  • Florian Lipowitz

other than Van Der Poel, that could well be the top 8 finishers. Other contenders for the top 8 include Oscar Onley (11th), Enric Mas (13th), Tobias Johannessen (15th).

NBC has Phil Liggett, again. I had heard he had retired; apparently not. He makes viewing the race less enjoyable.

💡 and, I would prefer "listen-only" to "video-only", much of the time.

----

There have been no mountains of note, only hills. This is how the rouleur ⚙️ A rider who excels at stages that are neither sprint-finishes nor high-mountains of Van Der Poel is at the top of the standings.

Wout van Aert is not there. Partially because of bad-luck on the cross-wind ⚙️ Cross-winds limit the effect of "drafting" on riders, sometimes enough to stop the normal game-mechanic of the entire field coming in as one or two groups., partially because of bad form, and partially because he doesn't want to be. ⚙️ https://cyclinguptodate.com/cycling/im-not-going-to-beat-remco-anyway-wout-van-aert-ponders-if-its-worth-trying-to-go-for-time-trial-result describes most of these

the Trakaido project continues.

Hopefully today (or possibly tomorrow) it will be at a "release milestone".

----

The three main issues I am dealing with:

  • LLMs are bad at state machines, and React has a lot of them.
  • LLMs are bad at succinct UIs, and mobile apps need them.
  • The app was architected so most of the code was in Trakaido.jsx, and passed to the "Modes". But, with additional modes, it is now three-layers (Trakaido to Mode to Activity). And the functions being passed (like playAudio) should be imported directly by the activity. This refactor, somehow, is beyond the LLMs unaided capabilities.

So, after 90 minutes of trying and failing to get it to work, I reverted and am doing a more hands-on approach of re-factoring.
