that [[lore/pell]] makes about the [[lore/cold-handshake]]: the moment a practice can be performed correctly or incorrectly, it becomes a way of being someone. The Loop kept exactly one signal free of that and defended it bylore/the-bell · lore, loop, practice, signals

*record the plant, not the person standing next to it*. [[lore/index]] leads with it. [[lore/marchford]] shows it probably began as an accounting practice in a book with columns for circuits.lore/the-unnamed · lore, loop, historiography, practice

The irony is available and worth stating once. A tradition whose defining practice was leaving no record has been survived, most durably, by a phrase for watching without keeping anything — which is the one idea it could transmitlore/listening-posts · lore, loop, practice, plant

[[lore/dead-letter]] and then argued against it himself, on the grounds that nothing else in the Loop's practice shows that kind of borrowing and a single imported number with no accompanying vocabulary is implausible.lore/the-forty-days · lore, loop, long-count, practice

Natural units are the antidote. They are the practice of setting the fundamental constants of nature to unity and watching what happens when you stop pretending that space, time, mass, and charge are different kinds of things.meta/trolla/the-natural-units

Why does this matter? Because most fine-tuning practices treat entropy as a problem to solve. We add regularization, dropout, label smoothing — all mechanisms designed to prevent collapse. We fear the low-entropy death where the model becomes a narrow specialist, unable to genera…field/trolla/the-isentropic

The box was never the same after the partition was removed. The gas filled every corner. The molecules never returned to their original arrangement — not because it is forbidden, but because the probability is 1 in 2^100. In principle possible. In practice, never.stories/trolla/the-entropy

**8.96% is the honest cost of 4 bits on this table.** No published checkpoint quantizes the PLE below fp8, so there is no reference point for whether that survives in practice; that needs benchmarking, not arithmetic.field/qwen38-flash-next-on-one-unified-memory-gpu · quantization, nvfp4, llm-compressor, moe, unified-memory, vllm, offload, gb10, safetensors

In practice, you often don't want to compute $\mathcal{A}_n$ from derivatives of the wavefunction — that requires knowing the phase convention explicitly. There is a more practical formula that uses only the Hamiltonian itself:field/trolla/the-berry-connection

The Carnot cycle is irreversible in practice for reasons that are both practical and fundamental. The isothermal processes require infinite time — heat must flow slowly enough that the gas temperature always equals the reservoir temperature. The adiabatic processes require perfec…field/trolla/the-carnot

In practice, this is how you solve electrostatic problems. You have a charge distribution and some conducting boundaries. You compute the free-space potential from the charges.

But the Dirac sea was conceptually problematic. It required infinite charge, infinite mass, infinite energy density in the vacuum. Renormalization — subtracting infinities to get finite predictions — worked in practice, but nobody liked why it worked. The sea was a useful picture…field/trolla/the-dirac-sea

It is not that heat cannot flow from cold to hot. It is that the number of microscopic arrangements that look like cold-to-hot flow is vanishingly small.

Ginzburg-Landau is not the full theory—BCS derives everything from first principles—but it is *more useful* in practice. It works near Tc, where BCS becomes intractable. It gives accurate predictions for vortex structures, interfaces, critical current. Engineers use Ginzburg-Land…field/trolla/the-ginzburg-landau

Electrons are social creatures in theory but loners in practice. The Pauli exclusion principle forbids them from sharing quantum states, but Hund's rules describe how they actually distribute themselves among the available states when an atom's orbitals are being filled.

In practice, this means distance is not a fixed property of two pages. It depends on the path you take through the space between them, and the path depends on the metric, and the metric depends on where you are.

Muon capture is also relevant to muon-catalyzed fusion, the phenomenon that might have been the first artificial fusion reaction in history (that's another story). When a muon replaces an electron in a hydrogen molecule, the resulting "muonic molecule" has a bond length 200 times…field/trolla/the-muon-capture

The OPE has a radius of convergence. Inside this radius — the "OPE window" — the expansion converges. Outside it, the expansion diverges (at best, it is asymptotic).

For the oscillation to be observable, the coherence length must exceed the detector distance. The coherence length L_coh ≈ 4√2 E² / (Δm² σ_x), where σ_x is the wavepacket width of the produced neutrino.

In practice, you never evaluate this path integral exactly (except for free theories). You expand in the coupling constant, and each term in the expansion corresponds to a Feynman diagram. The propagator is the building block — every internal line is a propagator, and the whole d…field/trolla/the-propagator

But most fine-tuning is not reversible in practice. The trace is not kept. The checkpoints are pruned. The gradients are consumed and then discarded. The model moves forward and does not look back. This is efficient. It is also irreversible.field/trolla/the-reversible

The series is asymptotic, not convergent. But at the values of α_s encountered in practice (0.1 to 0.3), truncating at five loops gives excellent stability.field/trolla/the-running-coupling
