🔴 ¿Por qué gotea la puñetera tetera? ¡¡¿POR QUÉ?!! Tengo 31415926535 cosas que hacer, pero he parado todo para incursionar brevemente en el excitante mundo de la mecánica de fluidos y comprender por qué sufro este tormento cada vez que pido un té. ¡No estoy solo! En 1956 un tal Markus Reiner, científico y reólogo¹ israelí, se hizo la misma pregunta y trató de responderla científicamente. Reiner pensó que la tetera gotea por el efecto Bernoulli, un fenómeno conocido desde hace siglos que dice que la presión de un fluido baja cuando sube su velocidad. Según Reiner, al inclinar la tetera se reduce la cohesión interna de las moléculas del té y esto las «pega» al borde, provocando el goteo. Pero Reiner estaba equivocado. Resulta que la tensión superficial del agua y la adherencia entre el líquido y el metal tienen mucho que ver en un fenómeno que es bastante más complejo de lo que parece. A tenor, al menos, de lo que dice una publicación científica de 2010² y unas investigaciones de 2021.³ También se quedaron por el camino las explicaciones que atribuyen el goteo al efecto Coandă.⁴ ¡Ah, el fascinante mundo de la hidrodinámica! 😅 Como especie, hemos tardado más en comprender esto que en enviar un paisano a la Luna. 🟢 ¿Y cómo tiene que ser la tetera para que no gotee? Pues tampoco es fácil. La tetera ideal tiene un recubrimiento hidrófobo en el pico, que evita que el té se «pegue» al recipiente. Y su pico es cortante, no redondeado. La tetera perfecta no tiene una salida recta —como la de mi vídeo de abajo— sino curva: el líquido sube… y después baja un poco antes de abandonar el recipiente. De este modo la gravedad contrarresta la querencia del líquido por «pegarse» al material. 🟢 Cómo verter té sin necesidad de una fregona ¡No la llenes mucho y viértelo deprisa! Así el té sale con mayor velocidad, lo que reduce la adhesión a la tetera… y el goteo. Muchas gracias por leer hasta aquí. Tengan un buen día y dejen de insultarse en las redes sociales. Saludos cordiales de su amigo, — Jaime Gómez-Obregón Presidente del Observatorio de los Observatorios Públicos de España y reólogo amateur especializado (desde ayer) en teteras. _____ ¹ Por lo visto, la reología es la rama de la física que estudia «la deformación y el fluir de la materia sólida y líquida». ✅ ² Wetting Controls Separation of Inertial Flows from Solid Surfaces, journals.aps.org/prl/abstract/1… ³ arstechnica.com/science/2021/1… ​⁴ en.wikipedia.org/wiki/Coandă_ef…

I find it completely unfair that Ukrainian 🇺🇦 @AndriyVolokitin has to play vs. Nepomniachtchi 🇷🇺 He is allowed to play under "neutral" flag, despite being officially registered under the Russian 🇷🇺, being sponsored by Potanin🇷🇺, having received orders from the Kremlin 🇷🇺.

@VBkramnik @BigTurt69 @chesscom @chessdom "Never event hint" but you posted this, raising suspicions on GM Navara. He explains quite well in his post why your post could affect his reputation. I think here you are picking the wrong "enemy" and making a huge mistake.

@yannToskov @HansMokeNiemann Science is about describing previously *unknown* phenomena, not *new* phenomena. Leela Zero's early h4-h5 is exactly the same: an advance to a deeper understanding of chess through a concept that was previously *unknown*.

Acabo de rebre aquest correu de l'escola. Ho trobo indecent, inhumà i vergonyós. Jo no pago l'escolarització del meu fill xq facin vaga a favor d'uns terroristes. Així no!! El meu fill anirà a l'escola!! 👇👇👇 Benvolgudes famílies,  Us informem que les organitzacions sindicals CGT i SO han convocat una jornada de vaga general per la situació a Palestina per aquest divendres 27 de setembre de 2024, de 0.00 hores a 24.00 hores de durada, que afecta al conjunt de treballadors i treballadores del sector públic i privat de l'àmbit territorial de Catalunya. Des de l'escola, pel que fa a l'horari lectiu, s'oferirà serveis mínims que consten de 2 mestres per cada 4 grups, per tant hi haurà un total de 5 mestres per a tots els grups. No es realitzaran les activitats habituals donades les circumstàncies. #SalvemCatalaunya

@IglesiasYosha Cool stuff! I think it is a bit early to introduce it as an AI “that plays like a human” with accuracies around 60% but it seems very promising! Can Oracle explain the moves’ rationale? this could help support whether reasoning is somewhat human-like

I've created Oracle, the first AI capable of playing chess like a human at any level, from beginner to super-grandmaster! Oracle is now open-source and you can download her code from my GitHub. I explain her functioning, based on GPT and Stockfish, in an article and a video. 👇

@LevAronian i love the subtle message of this tweet and esp the amount of humor! let me add that most of the AI models already have a decent level of stats, probability, etc. Models will need some machine *un*learning to match the human counterpart ;)

With chess becoming more popular and AI offering new opportunities , we need a RoboKramnik in every major city. A robot that finds suspicious players, and forces them to play OTB matches against Vlad’s AI clone. We chess players deserve our own CAPTCHA!!

@TDataScience it would be nice from your side to add one or two sentences when you reject a story though (especially if the author is trying for the first time and has read the guidelines). Smt like “story-telling should be improved” or “content is already widely covered” would suffice.

@VBkramnik @quizzerrrrr @kishor_bidya You need to determine the baseline of the player to constrain the “severity” of the anomaly. Then you will be able to provide real numbers instead of subjectively assessing that is “impossible”. People need easy-to-digest numbers.
Damià Benet@dbenet4

@VBkramnik @NikolaosNtirlis @Kazuma69371 The first thing to determine is the “baseline” (expectation) of a player’s performance. Only then, one can evaluate the existence of an anomaly. If found, it should be conveyed in a time-series plot with the baseline (including variance) and observed player performance.

@quizzerrrrr @kishor_bidya This performance is 3068, no such performance EVER otb in that long streak of games against top 10 players, by HUGE MARGIN. I do not care who performs that, but it is just impossible in practice, and must be punished imho, whoever did that. Otherwise cheating will prevail
