Artificial Gravity

xkcd.com/3111/
Comic. PERSON 1 [pointing to blueprint of a spacecraft holding a capsule on one end that is shaking back and forth] To produce artificial gravity during the voyage, the crew capsule is kept in constant motion. PERSON 2 with ponytail: Wouldn’t it make more sense to spin it instead of shaking it, so the acceleration is steadier? PERSON 1: ...Listen. You, I, and the crew *all* wish we’d thought of that before launch.

Global Ranking

xkcd.com/3110/
4-panel comic. (1) [Person 2 with white hat stands behind Person 1 who is seated at desk with laptop] PERSON 1: I’m ranked 7,145,000th globally on this chess platform. It’s hard to be ranked that low in *any* activity. (2) PERSON 1: Few pastimes even *have* 7 million rated players. Until the internet, it wasn’t really possible. You could be this bad, but only unofficially. (3) PERSON 1: So in a sense, I’m worse at chess than anyone was at *anything* for most of human history. PERSON 2: Why are you still doing it? (4) PERSON 1: Well, no human has ever had this many friends to play with. PERSON 2: That person is calling you some very obscene names. PERSON 1: Our friendship is complicated.

Exoplanet System

xkcd.com/3103/
Comic. [planets and astronomical bodies in various shapes with comments pointing to them] Typical Exoplanet System: Giant planet orbiting so close that it’s actually rolling on the star’s surface; Hot Jupiter; Mini Neptune; Planet that could be habitable, if there’s a form of life that hates water but loves acid and being on fire; Cold Jupiter; Potentially habitable void; Hot Mars; Planet that may actually be in the habitable zone, according to a very optimistic modeling paper by some desperate postdocs; There’s a pulsar here but it’s probably fine; A waterworld paradise with beautiful oceans and warm— Wait, no, we just got new measurements, it’s a hellish steam oven; Mini Pluto; Earthlike data artifact; Wet Saturn; Either a gas giant or a fist-sized rock, depending which calibration method you use; Faint dust cloud that will cause several papers to be retracted; Somehow this whole system is smaller than the orbit of Mercury?!; Planet whose surface may host conditions suitable for rocks

Reading a Big Number

xkcd.com/3102/
Comic. Thought Process While Reading A Big Number: 54,000,000,000,000,000,000,0000,0000,054,000"000,00c2ef46 [comments progress along the line, approximately every 3 digits] (1) 54! Great! I know that number. Solid start. (2) Oh, a comma and some zeros. Cool. Must be at least 54 thousand. (3) A second comma! I wonder if we’re talking population or money. (4) Yikes! If this is money, it’s a *lot* of money. (5) Why am I reading this? Whatever this number is, I’m not going to be able to visualize it. (6) All right, either someone made a unit conversion error or this is one of those incomprehensible astronomy numbers. (7) [4 zeroes between commas instead of 3]] Oh no. Is this a misplaced comma or an extra zero? I guess we’ll see if the next group has two zeros or three. If it’s two, we can at least hope the digits are right. (8) [4 zeroes between commas] Oh *no*. (9) [repeat of the digits 54] What is happening. (10) [a quotation mark in place of comma] Someone messed up real bad. (11) [final digits are c2ef46, cut off] Someone messed up real bad and I hope it wasn’t me.

Trojan Horse

[horse in between people] (3) One night, from within the horse, *another, smaller horse emerged!* [big horse looks behind at smaller horse] (4) PERSON: Our guards have been unable to determine the inner horse’s objective, but it has begun to show an interest in our oats.

MAGA va-t-il permettre de réindustrialiser l’Amérique ? Ou au contraire, la mener à sa perte ?

Les mesures protectionnistes du 1er mandat de Donald Trump nous donnent quelques indices.

Une pensée pour ceux qui, de Thierry Mariani (trinquant devant la prison de #Sednaya) à Rima Hassan (faisant la promotion de la Syrie d'Assad) ont soutenu ce régime sans jamais un seul mot pour le peuple syrien.

Miracle de la génétique :
il y a aujourd’hui 2,5 fois moins de vaches aux États-Unis qu’il y a un siècle, mais elles produisent en moyenne 6 fois plus de lait.

La productivité est la meilleur alliée de la réduction des émissions.

Si les émissions totales augmentent encore, celles par personne ont déjà passé leur pic :
- en 2012 pour l’utilisation des énergies fossiles
- dans les années 70 avec celles liées à l’utilisation des terres.

La meilleure preuve d’une croissance durable ? Car dans le même temps…

Être un complotiste, c’est en avoir tellement marre que le gouvernement nous mente 30% du temps, que l’on préfère plutôt croire des gens sur internet qui mentent 70% du temps.

Un potentiel exceptionnel de captation de CO2 a été découvert chez un micro-organisme présent autour d’un volcan sous-marin au large de la Sicile.

La startup @CyanoCapture utilise ce type d'organisme dans des tubes transparents où ils peuvent pousser et filtrer le CO2.
