I am ready to describe a little how to replace Special Relativity with a better kinematics that discards the non-mathematical notions of ‘Observer’ and ‘Frame of Reference’. Instead one would use geometry both with and without coordinate systems, without the encumbrance of ‘physical’ interpretations.

The full power of mathematics would be available.

Without ‘Frames of Reference’, we should no longer call the kinematics ‘relativity’. Just ‘kinematics’.

Let us proceed...

#physics #relativity

The #paperOfTheDay is "Foundations of the new field theory" from 1934. This new field theory today goes by the name of "Born-Infeld theory", it is an alternative version of classical electrodynamics.
Recall that in 1934, #quantum mechanics had recently been developed, but there was not yet any consistent #quantumFieldTheory , let alone a fundamental theory of elementary particles. In particular, classical (Maxwell) electrodynamics predicts an infinite self-energy if one assumes the electron to be point-like, and people discussed different ways to unify the picture of microscopic #physics .
Born-Infeld theory represents one possible scenario, modeled after Einstein's general theory of #relativity . Namely, a theory of electromagnetism based on general coordinate invariance, and the assumption that there is an universal maximum electrical field strength that no system can exceed. This gives rise to a Lagrangian that is structurally similar to the Einstein-Hilbert one. The field equations are then non-linear, but reduce to the Maxwell theory for weak enough fields in flat space.
Close to the center of an electron, the field strength is large, and the new theory is substantially different from classical electrodynamics: The potential is not singular at the origin, but always stays finite.

Later, however, many of the old mysteries got resolved with the quantization of Maxwell electrodynamics. On the other hand, Born-Infeld theory (much like general relativity) is strongly non-linear and hard to quantize with existing methods.

> [...} verknüpft mit dem Energieunterschied. Und der ist relativ gering bei diesem Prozess im Cäsium-Atom. Und die Frequenz, die dazu gehört, [... 9172631770 Hz ...] Und diese Mikrowellenfrequenzen, die konnte man schon in den 50er Jahren sehr präzise herstellen und kontrollieren. [...]

> Man hat jetzt 16 Stellen etwa Unsicherheit bei den besten Cäsium-Uhren. Das sind diese sogenannten primären Uhren, die in den nationalen Zeitinstituten stehen. Und diese hohe Genauigkeit ist für ein paar Anwendungen kritisch

So weit, so richtig.

> wenn ich eine sehr genaue Uhr einfach nur hochhebe, dann geht sie auch schon anders

Nein: Die Feststellung, dass eine bestimmte Uhr sehr genau ist (bzw. die Forderung, dass eine bestimmte Uhr sehr genau sein soll), beinhaltet gerade, dass deren Frequenz entsprechend genau konstant (alias "stabil") bleibt, insbesondere wenn sie "einfach" ("nur, ein wenig") hochgehoben wird.

Die "Mise en pratique" für die SI-Sekunde file:///C:/Users/peaq/Downloads/SI-App2-second.pdf verbietet gerade für die Primäruhren ausdrücklich Frequenz-Korrektur "für das lokale Gravitationsfeld" und somit auch "für gravitativen Hub" bzw. Absenkung.

#Relativity

🧵 Eddington's observations famously confirmed Einstein's prediction of the gravitational deflection of starlight passing near the sun.

This was a major step in the acceptance of General Relativity (GR).

So it might surprise some to hear that Newton had thought about this a lot earlier! 1/9

Master Index

A guided map across physics, biology, engineering, and AI—built around a simple idea

Persistence is not generated, but permitted.

Systems don’t fail because they “break.”

They fail because their boundaries were misclassified.

Core structure
state → constraint → resolution → persistence

From: - Titanic / Vasa / Challenger
– biological regulation
– AI hallucination & drift
– institutional collapse

Same pattern
only admissible states persist

This is the interface.
Start anywhere. Follow the path that fits.

i am the greatest #fortran programmer of all time. i wrote a program that does length contraction more accurately than my calculator. I am well chuffed with this considering how bad of a programmer i am.
