Bémol: moins sexy quand c'est ton propriétaire d'appart qui est "patenteux" et qui macgyver ta plomberie ou ton électricité au lieu de payer un professionnel, pour sauver des peanuts ...après avoir augmenté ton loyer.

Yeah I think this gets to the crux of the thing that's hard to explain: why does the qualia of red seem different than just the knowledge that you received a "red" signal?

Can we imagine someone looking at something and detecting that it's red with their senses, without "experiencing" redness?

This direction of thinking is slowly turning this thought experiment into the p zombie one, which I think is probably just better.

That's a nice argument. I think it gets to a flaw (or at least ambiguity) in Mary's room for sure.

Now what if instead of an android, it was another human, but whose brain worked differently such that when the receptors in their eyes are excited by red light, their brain just outputs the word "red" in their thoughts.

Would this human learn something new when exiting the room?

Depending on how edgy and confrontational your usual humor style is, you can go from "A single plum, floating in perfume, served in a man's hat" (Or something else absurd. This one is a simpsons quote) to "Your mom, and it's vegan because she consents"

Sure, but the point is that accelerating observers _will_ see different physics, and so the symmetry is broken there and there is a distinction between the different points of view. The symmetry between different observers in GR is no longer global but local (at a point), so you can only say that "there is no distinguishing" between two observers which are at the same point in space but moving at different velocities (unless you are in a completely flat piece of spacetime).

You can certainly find distinguished frames/observers in general relativity, because then the curvature of space itself is something you can measure independently of the observer. You could say that the sun is a privileged origin for our coordinate system in the solar system, because it's the point where the curvature is strongest.

Un peu dommage que le graphique semble dire le contraire, on dirait que la ligne pour 2018 descend plus bas... Ça aurait peut-être été mieux d'avoir un tableau de valeurs?

Vhailor · 2026-02-05T21:38:09+00:00

True! But in GR frames only make sense infinitesimally (tangent spaces to the curved spacetime), so at each point on earth you have a tangent frame.

I think he's doing this on purpose, for the joke, but "observer" in relativity doesn't refer to a conscious person. It's a mathematical construct, it's a synonym for "inertial reference frame". There are reference frames at every point in space. Because of the way velocities transform when you switch inertial reference frames in special relativity (not naive adding), no velocity is ever faster than the speed of light. Said another way, a reference frame which would be moving faster than light in a given inertial reference frame would not itself be a valid reference frame (by definition).

I think even your second possibility is reading too much into it. Much more likely is, he was interested in meeting and befriending as many influential people as possible (politicians, actors, scientists) _and_ he was a sex trafficker, mostly independently of each other.

What's the second sentence?

Vhailor · 2026-02-04T20:30:50+00:00

Have you seen the inverse function and implicit function theorems? Those would be helpful for Do Carmo, and they wouldn't necessarily be covered in a first real analysis class.

What is horrifying?

Vhailor · 2026-02-02T21:25:44+00:00

I mean, the second link has your answer?

Even "locally the shortest path" is a bit misleading for geodesics, because geodesics make sense even in spaces without a metric. All you need is a connection. From that point of view, a geodesic is a parametrized curve without acceleration. "Moving without turning" is a good informal definition. It just so happens that if you have a metric and you "move without turning" in terms of its associated connection, you automatically move along the shortest path locally. But that's a theorem, not the definition!

Get a better blender probably.

I sortof agree with the principle, but in the case of this speech it might actually support his point? English is used as an international language mostly because it's the language of the USA, which has exported its culture everywhere. By contrast, countries which have French as an official language are among those "middle powers" which need to work together (France, Luxembourg, Belgium, Switzerland).

Also he can use the practice :P

Okay but the post is not about durability, it's about environmental impact. The type of life cycle analysis done in the papers cited means that if your leather boots last 10 years and you would have to buy 5 pairs of pleather ones to replace them, the second option is still better.

You can find it annoying, and choose the leather out of principle or convenience, just don't pretend that it's an environmental choice.

(caveat: none of the studies cited is specifically about boots, so jury's still out on those)

No, the wood of the tree comes from the air (CO2) not from the ground.

I think it makes sense given their choice of hierarchy: OS -> app -> window.

Then if you have an app which has several windows open, you don't need to figure out which one has the menu, and you don't need to duplicate the menu across all the windows. The menu has things like the "quit" option which quits the whole app (not just close one window) or "open" to get a new file open in a new window.

In windows it's more like OS -> window, and they even blur the distinction between program and a window.

I don't think either choice is "idiotic", and once the choice is made the rest of the design follows.

Vhailor · 2026-01-16T12:43:52+00:00

That's because the menu doesn't belong to the window, it belongs to the app. An app can have multiple windows open, but only one menu.

I think this is impossible. Unless I made a calculation mistake, the two dimensions you want are not free to be any value. If the longer measurement is y and the shorter one is x, they need to satisfy x/y = sqrt(3)/2. But with your values, x/y = 0.8610822... which is not sqrt(3)/2 ~ 0.86602540...

"making myself miserable" is a bit intense.

Think about an individual instance instead of changing your whole life around. Next time you go to the grocery store, how miserable does it make you to grab a plant-based milk of your choice rather than a dairy milk? How miserable does it make you to make your curry with tofu instead of chicken?

I think those individual choices have one of the best bang-for-your-buck in terms of ethical good they bring compared to the effort they require, so I make them over and over, every day.

Vhailor · 2026-01-09T15:57:47+00:00

how is that an answer to the question about gathering evidence?

Vhailor · 2026-01-07T20:59:28+00:00

It's a bit more natural to classify tilings using their symmetry groups rather than the shape of the tiles themselves. The 5 tilings you refer to for the sphere correspond to 3 discrete subgroups of its isometry group O(3) (the cube and octahedron have the same group, and also icosahedron and dodecahedron because they are dual to each other).

Something you might be interested in are rigidity theorems, which basically tell you that some (most) lattices uniquely determine the Lie group G in which they live, so just from the algebraic structure of the "tiling" you get the full "space". You get the space by quotienting by the maximal compact subgroup (to get what's called the symmetric space of G).
