This is the category where the gap between reputation and substance is widest, because the subject rewards two very different videos that look identical from the outside.

The first kind spends its runtime on analogy. Neurons are like brain cells, attention is like paying attention, the model is like a very good autocomplete. It is pleasant, it is often accurate, and after forty minutes you cannot do anything you could not do before. The second kind uses one analogy to get you onto the ramp and then shows the actual arithmetic. Both get the same thumbnail treatment, and both are described as “explained”.

The measurement that separates them is density: what share of the runtime introduces something the previous minute did not already contain. Repetition of an idea in three different metaphors scores low here, and that is deliberate — it is the single most common way a fifteen-minute idea becomes a fifty-minute video in this subject.

Entries also carry a difficulty level, because “explained simply” and “explained” are not the same shelf, and the fastest way to waste an hour is to pick the wrong one for where you already are.

Comment ce classement est établi

Chaque vidéo ici a été mesurée sur les mêmes axes — quelle part de sa durée porte de l'information, quelle part est du remplissage, et à quelle seconde elle commence à payer.
