  • Atmospheric pressure is about 14.5 psi, but a US quarter is only about 0.72 square inches in area. As a result it’s 10.5 lbf in total. I think that should probably be fine? Like, I can’t pretend to be an expert here, but frankly I think my arsehole is made of sterner stuff than that

    I do wonder, though, if it’d create a steady airflow through your whole digestive system if you just left your mouth open. I bet that’d feel confusing







  • It actually makes sense once you know how it started! In the early 1900s Michelin wanted to encourage people to drive more (and therefore use tyres more), so they made a guide that was essentially a road trip companion. It had some instructions on basic car repairs, locations of mechanics and hotels, and of course good restaurants to visit along the way. Over time, the restaurant recommendations got particularly popular, so they leant into that




  • Edit: I’m stupid, didn’t realise that the video actually mentions this specifically. Although I think that comparing the afterburning thrust is a bit off without also mentioning that the non-afterburning thrust, the one used most of the time, is actually higher for the Eurojet

    While I do not mean to imply that military fighter jet engines can just be trivially hotswapped, I wonder if the Eurofighter’s engine could be adapted as a replacement? The Eurofighter itself has two because it’s a much larger aircraft, but the individual engines are actually pretty close in dimensions, weight, and performance


  • It has a active protection system which can handle incoming missiles, that will be a solid defence against drones too. Russia has developed an APS which they’ve used successfully in the invasion, but they only had it ready a few months before their full-scale invasion started, so it’s only on newly-built or fully-refurbished tanks. It also has the drawback that it was initially designed to deal with missiles; Ukraine figured out that it could eventually be overwhelmed by just sending enough drones at it to drain its relatively limited ammo, something that would be impractical with expensive missiles, but until then it apparently handles incoming drones pretty effectively. The Challenger’s one has the benefits of being designed with the knowledge of what drone warfare looks like

    It’s also worth noting that nobody publishes videos of drone attacks failing. A cheap little quadcopter with a grenade strapped to it is, ultimately, jut a way to throw a grenade unusually far. A tank like this can shrug off a grenade. Attacking them requires bigger, heavier, more expensive drones carrying bigger, heavier, more expensive munitions. Or you use the drone to sight artillery. But the point remains that even in the age of drone warfare, tanks are still harder to kill. There’s a reason both sides are still using them



  • I took some time to learn a whole bunch of consonants from different West African languages for the sake of getting names right while running a D&D game. This one gave me, as a native English speaker, even more trouble than the double-articulated ones
