    I've written in the past (see https://terrytao.wordpress.com/advice-on-writing-papers/implicit-notational-conventions/ ) about the useful implicit notational conventions in mathematics, for instance how in analysis the symbol ε is by convention understood to represent a small positive number, which can greatly assist in comprehending analysis arguments that involve manipulating such small constants (and conversely how an argument that uses ε to represent a negative or very large number will cause a lot of unwanted confusion).

    In fact, even plain old numerals have a lot of implicit conventions attached to them. Suppose for instance I use the numeral 100 in an estimate, e.g., ( f(n) \ll n^{100}). Just by virtue of 100 being a medium sized round number, I am signaling that the exponent here is some generic constant whose exact value is not worth optimizing for the current argument, or even giving an explicit symbol name such as 𝐶₀; the numeral 100 is intended as a place holder, and related numbers that show up shortly afterwards, such as 101, 200, or 50, will most likely be coming from the choice of the original exponent in the obvious manner. If in contrast I used a non-round number, e.g., ( f(n) \ll n^{76}), the connotations are quite different: readers may assume that the specific value of the exponent is important for the application, and that some attempt has been made at optimizing its value.

    It took me a while to realize that this convention is not universally understood, particularly outside the West; I've had students from non-western countries inquire as to where constants such as 100 came from in an argument I wrote, as they could not see how it was related to previous calculations!

    @tao It's a matter of precise subject area to determine who can play best the role of "round number" among, say, 100 and 128 😜

    Hay un tema que daba por universal y es que todo el mundo tenía voz interna. Pero hace un par de años nos destruyeron ese mito, ahondando en la diversidad de formas de pensar que tenemos.

    No os perdáis este artículo de @aberron sobre el tema.

    Yo tengo una imagen vívida de mi infancia más lejana, cuando aprendí a leer, que me ha durado hasta hoy.

    Yo "veo" el alfabeto como una U a izquierdas. La rama superior va desde A hasta KL, después gira hacia abajo hasta la QR y ahí gira a la izquierda hasta la Z.

    De hecho, donde todo el mundo ve "..UVXYZ" yo veo "ZYXVU...". Pero aún así no me confundo en el orden de las letras.

    Can people with normal colour vision see the text under "enter your code" in this screenshot?
    Is this a dark-mode thing that they didn't account for?

    @christianp My trick: select the light text and then it becomes readable.

    Which of these singing voices do you prefer?

    shevek,
    @shevek@mstdn.io avatar

    @evan I sing as tenor in choirs. But my favourite voice is alto, and it's a pity that very low numbers of women have a real alto pitch/color.

    Contratenors are fabulous, but their alto-flavour is not as velvet-like as alto woman.

    Bonan tagon, Fediversanaj geElefantetoj,

    Ĉu kutimas matenmanĝi en la trinkejoj/manĝejoj/restoracioj/kafejoj/aliejoj en via lando? Kion vi kutimas fari por la matenmanĝo? Mi legas vijn ĉiujn.

    Kion vi matenmanĝis hodiaŭ?


    :senyera: :flago: :lamancha:

    shevek,
    @shevek@mstdn.io avatar

    @chusgc Hejma matenmanĝo kun:

    • Bovlo da sezonaj fruktoj (ĉi-sezone, melono sed ankaŭ mango, fragoj...)
    • Kafo kun miksaĵo de avenlakto (memfarita) kaj sojolakto.
    • Unu sala tosto: avokado+olivoleo, aŭ butero + memfarita "vegemite" (ĉiaaj semoj + sojo-saŭco)
    • Unu dolĉa tosto: sezama pasto+ memfarita "melinazo" (pasto el linsemoj+mielo), aŭ arakida pasto+bananaj tranĉaĵoj+kakaa pulvoro, aŭ olivoleo+mielo, aŭ butero/freŝa fromaĝo + marmelado (kutime memfarita).

    @shevek@mstdn.io avatar

    @chusgc Dankon!

    Mi aldonas ke mi ĵus aĉetis specialan tason por kafo, kun bona varmoizolilo, ĉar mi malamas malvarmiĝon de kafo dum mi matenmanĝas.
