When Einstein literally discovered General Relativity.

Gravity is the curvature of Space Time. From that perspective, objects under gravity are traveling in a straight line.

But 0 is what you expect to see in that case: you have two forces acting on the body, of equal magnitude and in opposite directions, so the net force is 0, so acceleration is 0.

But if you jump out of a plane, you will see ~0. If gravity were a force, what would be the equal and opposite force acting on you?
> > Acceleration is measurable with a device called an accelerometer. Acceleration is not relative (like velocity), it's absolute.

The reason that you can't measure gravitation acceleration in free-fall in a uniform gravitational field[0] with an accelerometer is that all parts of the accelerometer are being accelerated together.

[0] The "uniform gravitational field" part comes from Einstein's equivalence principle, and it's pretty obvious that if the field were sufficiently non-uniform then one could expect strain gauges to indicate that the free-falling object _is_ being accelerated. Imagine you have a 10km long space ship near a massive body like Earth, or the Sun, then the gravitational field will not be uniform across that space ship, and strain gauges will a) let you know, b) will even be able to tell you the strength of the field and the heading to the massive object.

All these "gravity is not a force" arguments based on the equivalence principle are simply nonsense. The better argument is that gravity is both not a force because it only curves spacetime, and also yes equivalent to a force (especially when you do a Mercator-style projection of curved spacetime onto flat spacetime).*
Not trying to be snarky, but for this example, if we can compile to wasm, why not have the client compute this locally?

This would entail zero network hops, probably 100,000+ QRs per second.

IF it is 100,000+ QRs per second, isn't most of the thing we're measuring here dominated by network calls?

No, I read what you wrote and I meant what I said. Let me explain again: people are willing to do anything, even jobs they dislike, just to get a visa. That doesn't mean they'll want keep doing that shitty job once they get the visa and can start looking for workarounds. Otherwise there wouldn't be a shortage of staff in those sectors if all workers would stick around for long.

Unfortunately I think Linux kernel is one of the most notable examples in which case you have to compile with -O1 or up.
That's just because gravity is also accelerating the accelerometer, and the accelerometer can only measure acceleration relative to the body of the instrument.

I've heard this argument: Because gravity is the only force that acts on all objects, including the measuring object, this makes it not a force. This is not actually an explanation, it's more of a definition, and not a useful one.

Getting sick is not an unanticipated problem. A major illness or injury is.

Insurance has no business paying out for you going in for strep throat or the Flu or an annual checkup. These are normal things everyone gets multiple times throughout your lifetime, and should easily be taken care of via market forces for a very reasonable fee.

The problem with US healthcare can be entirely boiled down to a principle agent problem. Someone else is always paying, so no one actually really cares that much about the cost of things and the incentives always are to increase costs and use more services since there is no actual market competition.
Add the fact that, if legal marijuana is priced low enough to make black market dealers less common, the people selling the marijuana will now be forced to only sell to people 21+.

I’m not saying that this is the case as legal recreational marijuana sale prices in many legal states are high enough (due to taxes or artificial supply dampening due to restricting who can grow it and how much) to justify the existence of a black market, but if that was the case, I’d expect a drop off in youth usage.
If you are accelerating, the accelerometers will not "show 0". I have no idea where you are getting this notion from; it's completely wrong.
That's the acceleration you feel on the surface of the earth. But that's not an inertial reference frame. In an inertial reference frame gravity doesn't cause acceleration (kind of by definition).

The argument is that gravity doesn't cause acceleration, resisting gravity does. Kind of how spinning an object doesn't cause a centrifugal force, the real force is whatever forces it to stay on a circular path instead of continuing straight

Hmm, if you look at another comment here: https://news.ycombinator.com/item?id=41971973

It seems like the point is that the particle is actually not accelerating when it follows the one path through spacetime. It only accelerates when it's stopped by something (e.g. the surface of the earth).
Arabic is significantly more difficult for English speakers than a Romance language, but you're still able to draw a straight line from symbols to sounds.

F = ma so a = F/m.

In the scenario you’ve set up
m >>>>>> F, because the Earth is fucking enormous. So a will be extremely small but nonzero. A precise enough accelerometer would show you this.

Also your mountain accelerometer would show ~9.8m/s^2 plus the extremely small contribution of the rocket thrust, not 0.
What I noticed is that to not lose money, they need lots of brief visits. Do the checkup, come in later to review the test results, then schedule a follow-up to decide on a referral (or not). Everything after the first visit could have been done with a (voice-only) phone call.

Maybe video visits were supposed to make it easier to generate billing with less driving, but it didn't work out that way.

Ultimately I went with an HMO, where the doctors can provide the same minimal amount of care but not jump through hoops to do it.
Love the Hossenfelder reference (though she really needs to move to Bluesky...). That said, I'd love if someone could explain some physics to this noob:

If you jump out of a plane, at t=0 you'll not be moving (relative to the earth), at t=1 you'll be moving a bit (relative to the earth), and at t=2 you'll be moving even faster. How is that not acceleration? A quick wikipedia rabbit hole from "Accelerometer" --> "Inertial Reference Frame" --> "Fictitious Force" led me to this:

A pseudo force does not arise from any physical interaction between two objects, such as electromagnetism or contact forces. It is just a consequence of the acceleration a of the physical object the non-inertial reference frame is connected to, i.e. the vehicle in this case. From the viewpoint of the respective accelerating frame, an acceleration of the inert object appears to be present, apparently requiring a "force" for this to have happened.

They use the example of a passenger in an accelerating car, which makes sense. And there's some discussion of how the earth is rotating and thus has angular (?) acceleration, which also makes sense. I think this is what Hossenfelder is referencing by "the earth is accelerating you upwards". But the rotation discussion seems completely unrelated to gravity, no? An asteroid that isn't spinning would still exert gravitational (pseudo-)force, as all massive objects do of any size. Surely a person standing on a non-spinning asteroid in deep space isn't being accelerated upwards?

At the end of the day, I guess I'm missing why exactly "free fall" is the same thing as "no forces acting upon you". To my cynical arrogant brain, this reads like the physicists are harping on an unnecessary terminological thing, namely that a "force" is defined as "a physical interaction between two objects". In other words, its quantum bias, in the original sense of quantum; why can't objects interact with the continuous field of spacetime?

I'm commenting on your quote because her explanation especially "we have a machine with acceleration in the name, thus that's what acceleration is" set off a million alarm bells in my head, philosophically speaking!

Who is doing business?
Accelerometers don't measure acceleration, they measure the difference between the force on a mass on springs and the body of your phone. If you drilled a tiny hole and pulled the mass up, the sensor would think the phone was being pulled down.

Acceleration due to gravity has an important property of acceleration in general: radiation. Spiraling black holes emit gravitational waves, in the same way that an accelerating electric charge emits light. There are free falling reference frames where uniform gravitational fields can go away, but the gravitation of a massive body isn't uniform and can't be eliminated by changing the coordinates.

The relationship between gravity and fictitious forces is an important stepping stone, but it does not have all the properties of a fictious force, only some of them.

Are you expected to replace your screen often? I don't think I upgrade and replace either one much faster than the other. Usually get a new monitor and a new PC every 4 or so years.
Force is not acceleration.

That is extremely easy to understand but somehow you and all of these "eminent scientists" fail to grasp it.
Suppose you were in a free falling box in a strong gravitational field. Is there an experiment that you can do within that box which would measure the acceleration? I think no. Not directly (perhaps you might get clever and do something with tidal forces). And if you can't measure it, why do you assume it's there?

By contrast, if you strap a rocket to the box, it's quite easy to measure the acceleration from within the box.

To argue that the acceleration exists because the position changes is to assume that the observer's reference frame is somehow the correct one, and Einstein has showed us that that's a problematic assumption.

> Go's concurrency is unsafe? Rust's concurrency is automatically safe?

Yes and yes...

Rust statically enforces that you don't have data races, i.e. it's not possible in Rust (without unsafe hacks) to forget to guard access to something with a mutex. In every other language this is enforced with code comments and programmer memory.
I am sympathetic to the author's thesis. I favor the idea that gravity is a different thing from the other fundamental forces, and possibly an emergent phenomenon rather than a fundamental thing in its own right.

But, I don't buy the argument made here:

> To call gravity a force, is to privilege flat space as somehow being special.

Flat space is special, and we didn't make it special.

This is taking an important aspect of known physics---that there exist various symmetries and all elements of the corresponding group are equal players (there is no privileged reference frame, positive charge and negative charge are indistinguishable save for their oppositeness, etc.)---and attempting to apply this principle to spacetime curvature. But the zero curvature state is a unique one that is differentiatable from the others. It's the only one where a circle is perfect, having circumference 2 * pi * r. And pi is a fundamental invariant of geometry, curved or otherwise. The mathematics privileges flat space. Further, experiments can be constructed to detected whether we are in flat space or not [1]. That wouldn't be possible if the whole concept of flat were only relative to an arbitrary frame.

Mapping Germany's 'Dangerous Zones' and Police Overreach
ÜberwachtAtlas ("Surveillance Atlas") is a project that shines a light on so-called "dangerous areas" in Germany, where the police have expanded powers to conduct suspicionless identity checks and searches of citizens. This map aims to raise awareness about the potential infringement of civil liberties, concentration of power, discrimination, and lack of transparency surrounding these "dangerous zones." By crowdsourcing data and mapping these areas, the project seeks to enable deeper analysis, comparison, and public scrutiny of this growing trend towards increased police surveillance and control in germany's federal system.

The iMac is basically the same as the M4 iPad Pro, and the iPad Pro doesn't have a chin.

You do just sit there. In the GR-realism view, the only thing particles _ever_ do is self-propagate forwards in time.

The problem is, this means the particle’s definition of “time”. Spacetime is 4D, and this can be any timelike direction. That’s what causes it to appear to move, from the perspective of someone whose time vector is pointed differently.

Then time can be curved, which reorients said vector as the particle propagates through it. That’s gravity.
Last time I posted that I'd work on my first PCB. That somehow fell off the table, can't really grip where the time went.

Job is very stressful as Q4 is peak-season for us. Managed to stick to some healthy habits though, like doing sport regularly and trying to eat less junk food. It ain't much but it's something I guess.

Also made a good deal on a broken Kitchen Aid machine. I want to repair it for a friend of mine who would like to have one but can't afford it right now. I think that will be a nice christmas present. Really need to get that going though, when time flies again.
For me, AI helping with writing email has been wonderful. I do a lot of email that is fairly generic and really just needs a basic template for replying or informing people. For those tasks it works great. I also had a more serious email that I wasn't sure how to respond to and needed to make sure the tone was appropriate and AI helped me get a good draft to work from.

Email is one of those things that I would put off as I just found it hard to get started and would worry about grammatical error and trivial mistakes that people seem to focus on more than they should. AI has helped me just be better at email.
Polling paradox: what shapes the numbers?
Yeah I get that sentiment. My concern is that the ways in which the train system would grow to handle the new scale might be non-ideal. Eg it would probably be higher prices, more packed trains, smaller seats, long before it's what I imagine is what you're hoping for which is more trains, better trains, more tracks. Although long term that might be the better approach!
I'd recommend reading up on Private Cloud Compute, the system that Apple designed to implement this: https://security.apple.com/blog/private-cloud-compute/

It's pretty impressive. I read it back in June when this came out, but the basic gist of it is that everything that _can_ be done on device _is_ done on device, and everything else is run in a _provably_ secure and private cloud environment.
It would also be simpler to just ban cigarettes and alcohol and all of those things that the State of California knows to cause cancer. Complete prohibition is not the only policy tool we have, and indeed it's usually a pretty bad tool.

I don't think this is true. Modern schools give many different opportunities to express intelligence in novel ways. I took music theory in high school, we wrote chorales. We had robotics too, for those that wanted it.

It's true though that if you're learning math the focus is on learning math, not theorizing new branches of mathematics. The reason being that most topics are cumulative. You can't study abstract algebra if you didn't pay attention in high school algebra. In that way, they force conformance. But largely I think this is a good thing.

This sort of thing also applies to English/Language Arts. In order to comprehend more complex media, you have to be able to comprehend simple media. Often, I hear people lament about how school didn't teach them about real life. Typically, the reason why is because they didn't pay attention in English class. There's a lot there.

Also, intelligence is virtually worthless without knowledge. Intelligence just describes potential. If you don't use that potential, it's no different than if you had no intelligence at all.
> and make only OK money

Sounds like it has a lot to do with the system.

In the US, because of employer insurance, the cost of insurance is mostly hidden from patients. The cost of medical care is similarly opaque -- consumers expect routine checkups to be essentially free, and sick visits to cost next to nothing. Insurance companies are always trying to drive down their costs, and control access for a huge set of patients.
Surprising that my personal account, all of which is a truthful reflection of my own lived experiences in both urban and countryside settings, is considered "ignorant."

I'd be interested to explore the reasons and/or psychology behind your judgement.
I don't think that's a controversial thesis at all.

The Manifesto of the Futurist Painters specifically cited cars and industrialization among its main inspirations, and both Mussolini and Hitler largely garnered public support from their opposition to Communism. Communism was profoundly a response to industrialization. Moreover, the kind of state regimentation that was central to authoritarianism of all kinds, including Fascism, would have been impossible without cars and impossible without industrialization.

Fascism without cars or industrialization would have had nothing in common with the Fascism we actually got.

If you built an accelerometer using only components that feel the electric force, would you be able to detect the acceleration caused by the electrical force?

I.e. part of the reason gravity is fundamentally different is that it's universal: everything obeys it, including the trajectories of radiation.

This makes it functionally a different thing than every other force, since for all other forces you can build a tool that would measure acceleration because there is always something available to you that is not affected by that other force
I’m interested to see where this goes. That said, I am now planning to delay upgrading my iPhone 11 Pro until iPhone 18 comes out.

IMHO Apple and everyone else is moving way too fast with adoption. The deployment surface of iPhone is huge - I’m interested to see how Apple handles their first really serious issue (like “diverse Nazis”).

Also - current AI programs are complete and total pigs. iPhone 16 offers 8GB of memory and 1TB storage. I know the programs need the memory and so forth but still. I get it but I’m also going to wait now for the vendors to figure out the new future.

In the meantime, I will watch and wait. Plus, if Apples history is any indicator, the first 2-3 versions will be lame but then around 4 or 5 it will take off.
