The inverse-square law singles out no particular scale of…
““The inverse-square law singles out no particular scale of length as special and has an infinite range. To explain objects of particular sizes requires a balance between gravity and some other force. Boscovich proposed a grand unified force law which included all known physical effects. This was his 'Theory', as he called it. It approached the inverse-square law of Newtonian gravitation at large distances as required by observations of the lunar motions. But on smaller length scales, it is alternately attractive and repulsive and so gives rise to equilibrium structures whose sizes are dictated by the characteristic length scales built into the force law.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Physical laws can be scale‑independent, yet observable structures arise from competing forces that set characteristic sizes.
In simple terms: Scale‑independent laws plus competing forces create specific sizes.
Key Takeaway
Recognize how multiple forces shape natural scales.
