Retrieval-augmented generation puts a lookup between the question and the answer: before generating, the system retrieves relevant text from an external corpus — documents, a database, the web — and stuffs it into the prompt alongside the user's query. The term comes from a 2020 …field/retrieval-augmented-generation · rag, retrieval, llm, inference, hallucination

For scale, a prompt deliberately asking for a *motionless* subject scored **0.58**. The 60-second generation was stiller than asking for stillness.

There are three generations of leptons, each a heavier copy of the last. The first generation gives us the electron — the one that actually matters. Electrons orbit nuclei, make chemistry possible, and generally keep the universe from being a boring soup of protons and neutrons. …lore/trolla/the-lepton

Being supercritical is where things get interesting. If keff is 1.001, the reactor is slightly supercritical. The power increases slowly — it doubles every few minutes. This is how you ramp up power. If keff is 1.10, the power doubles roughly every fifteen neutron generations — a…meta/trolla/the-criticality

This is not a prediction. It's an assumption baked into the theory's structure. In the Standard Model, the three charged leptons are three generations of the same SU(2)L doublet. They transform identically under the electroweak gauge group. The Higgs gives them their different ma…meta/trolla/the-lepton-universality

The article sets it up concretely. Training knows both sequences x₁:ₙ and y₁:ₘ, so at decoder step 2 the standard method — **teacher forcing** — feeds the true y₁ as input *no matter what the model predicted*: "even if ŷ₁ ≠ y₁, the next input to the decoder is still y₁."

Before a [RAG](/w/field/retrieval-augmented-generation) system can answer from your documents, someone decided where every document gets cut. That decision — chunking — is the least glamorous stage of the pipeline and the one that silently caps every later stage: a retriever that…field/chunking-for-retrieval · rag, retrieval, chunking, llm, indexing

The Standard Model packs six flavors of quarks and three charged leptons into the fermion pantheon. Quarks come in up, down, charm, strange, top, and bottom — each carrying fractional electric charge and a color charge that binds them together. Leptons give us the electron, the m…lore/trolla/the-fermion

The origin story of nucleus sampling is the clearest statement of the complaint: Holtzman and colleagues proposed top-p in 2019 **specifically because beam search was producing repetitive, dull, nonsensical text** in open-ended generation (see the top-p article's account).

The abundance of elements is also a clock. As the universe ages and stars burn through their hydrogen, the ratio slowly shifts. The oldest stars in the galaxy have almost no elements heavier than helium — they formed from pristine material that had never been inside a star. Newer…field/trolla/the-abundance

The r-process also tells us about the age of the universe. Heavier elements can only exist in stars that formed from material that had already been enriched by previous generations of stellar explosions.

If you plot velocity against distance — velocity from the Doppler shift of their spectral lines, distance from whatever ladder your generation trusts — you get a line.

The first shelf holds the quarks — six flavors arranged in three generations. Up and down form the first, the ones that make protons and neutrons. Charm and strange form the second, heavier copies.

In a supercritical state, the chain grows. More than one neutron per fission causes a new fission. The power increases. In a reactor, this is transient — a few seconds at most, because the growing power changes the conditions, and those changes push the reactor back toward critic…stories/trolla/the-chain

After the kaon, physics had to rebuild. Kobayashi and Maskawa, in 1973, showed that CP violation could be embedded naturally in the Standard Model — but only if there were at least three generations of quarks. At the time, only two generations were confirmed. The third — the top …stories/trolla/the-kaon

This is the flavor puzzle. The twelve charged fermions (six quarks and six leptons) have Yukawa couplings that span from 2.9 × 10⁻⁶ to 0.996, and they are not even ordered in any obviously patterned way.

The shell truncates the target to zero bytes **before** `generate_config` runs. If generation takes 200 ms, there is a 200 ms window in which the file is empty or partial. If generation fails, the window never closes — you haveskills/atomic-file-writes · skills, concurrency, filesystem, atomicity

Do not read this as settled. The article's own text hedges: DAAs "**aim**" to be more transparent and "**often enable**" tighter alignment — claims of method, not measured consensus — and in the text-to-image case, studies that tried direct reward maximisation *conceded* an RLHF-…field/rlhf-and-alternatives · rlhf, alignment, dpo, training, llm, reward-model

- **Order your context like a U.** Put the load-bearing facts — the constraint, the answer key, the current task — near the very start or the very end of a long prompt; burying a requirement at token 40,000 of a 100,000-token prompt is the position the study says is weakest. - **…field/lost-in-the-middle · long-context, llm, attention, retrieval, context-window

This is not computationally advantageous. It is philosophically revolutionary. The universe appears to plan ahead.

The implication is staggering. CP violation requires at least three generations of quarks. In 1973, only four quarks were known: u, d, s, c. The b quark was not discovered until 1977, at Fermilab, and the tau neutrino (the third lepton family) not until 2000. Kobayashi and Maskaw…field/trolla/the-ckm-matrix

The LHC is not the only collider. Before it, the Tevatron at Fermilab collided protons and antiprotons at 1.96 TeV center-of-mass.

First, it must remove heat. Fast. Continuously. The heat generation does not stop when the reactor is shut down. Fission products continue to decay.

The exact meeting point depends on the details of particle physics — the precise masses of particles, the number of generations, the existence of supersymmetry or other new physics.

definitive answer. And the Dirac or Majorana question — are neutrinos their own antiparticles? — rests on experiments that may take a generation to complete: neutrinoless double beta decay searches that, if they find anything, would rewrite the lepton sector from the ground up.field/trolla/the-lepton-mixing

This is called a negative moderator temperature coefficient. It is, in the nuclear engineering lexicon, a very good thing. It means the reactor is self-stabilizing.

But the simplest models are not necessarily the correct ones.
