For collision detection using screen space might be easier, i.e. instead of looking for collisions between lines one wants to draw analytically, just try to draw them and check if all the pixels are background pixels.

I've spent that time slowly gathering evidence from the literature to validate my hunch. That is most likely the wrong way to go about this, you should probably look for evidence that your hunch is wrong, that it is in conflict with

Not a physicist and only read the abstract, but that does not sound right. One frequently hears that one can recover classical mechanics from quantum mechanics in the limit of Planck's constant becoming zero but not even that seems to

No, but those are battles that require political solutions, nothing you can realistically hope to address with recommendations.

Can we not have anonymous age verification, the ID card signing some one-time challenge that the date of birth is before a certain date? And then just force everyone to implement this to prevent circumvention by going to smaller sites that

If everyone runs their computer 24/7 or if you are willing to live with the limitation that somebody can only write you an email when your computer is turned on, then you can do that. And of course if everyone runs their computer 24&#x

You can not predict the future state from the current state, not even in principle. Measure the spin of an electron along two different axis, to the best of our knowledge - or maybe just my - the result of the second measurement is not pred

"Random" is a property of your mind, not of the world. Limited information about the initial state is one source of randomness but not necessarily the only one. Whether there is true randomness in the universe is at very least a

For most people it does not matter what people are using at the other end of the world, they will use the locally dominant platform.

I mean there is of course a way to fight and win that battle and it is regulation, write things like interoperability and data portability into law and enforce it. I was more thinking of things that can be done without enforcement in the in

You are not switching away from WhatsApp because that is what everyone is using, not because it would be harder to use Signal.

Adding noise may make it a bit harder but does not fundamentally change anything. The measurements, especially over a network, are noisy to begin with and adding a delay will only add another noise source. Aside from that, time invariance i

Are there any languages that properly support this, i.e. where you can express at the language level that the compiler should refrain from being to clever? If not at the language level, are there compilers which you can ask to keep an eye o

[...] plenty of parameters optimized using a learning process [...] Would that not make fitting a degree 1,000,000 polynomial a neural method? I also think gaussian splats encode the same information as NeRFs, which have neural in the na

I also find their usage of the word neural very confusing but this is how they explain it. A Gaussian Splat, instead, is a neural representation unit that is not limited in this way – not only can it be assigned anywhere in XYZ/3D sp

That seems to me to be the wrong way to think about this. I don't think that we have any evidence that a particle stores its position in the same way we might do in a physics simulation, it just sits at some position in space time. Wha

Of course, any system will need maintenance. My point was that you need the capacity to do the maintenance and you have to be able to do it cost effectively. That means in the case of Starlink it might actually be important to have Starship

All the numbers I have seen were 5 to 7 years of operational lifespan but I can not find a primary source from SpaceX at the moment. I think I also read that there are plans to increase the lifespan eventually with larger satellites, deploy

Starlink is nothing that you deploy and then you are done. When you have launched the last satellite, then the first ones launched will have reached the end of their lifespan and you essentially have to start over, deploy the entire constel

How many flights do they want to get out of each rocket? For Falcon 9 the current record seems to be 18 which would be about one moon mission. They will have to go far beyond that, otherwise it would essentially be an expendable system - on

Sure, everything going through the atmosphere at supersonic speeds will lose at the very least a couple of atoms here and there, but that was not the point and that does not make thermal protection tiles an ablative heat shield.

Insulating tiles are not an ablative heat shield, they are a thermal soak heat shield. Ablative heat shields are non-reusable as they work by slowly burning off material which creates a cooler boundary layer between the plasma and the heat

How does this work out? Instead of one rocket they will have to launch a dozen or so rockets for one visit to the moon. Why did they choose this option to begin with? And is cost per time on moon not a bit misleading, just stay longer and t
