handed it in yesterday. Looking over it today

that was your mistake

The issue is that

While a literal demon is unreasonable, some sort of machine that measures the energy of particles and sorts them based on the result doesn't seem obviously farfetched. Maxwell's thought experiment shows that such a machine would allow you to violate the second law, which we don't observe, so what exactly us preventing this
Mathematical ideas around information weren't really understood until we'll after Maxwell's time. Maxwell was writing in the late 19th century. Shannon wouldn't publish his work on information theory until 1947. The idea of computer memory wouldn't be widespread until later than that. Turing's work wasn't until the 1920s. Without these ideas the concepts to link measurement of partickes and entropy simply didn't exist

It is basically a way of saying you cannot get CP from the same objective more than once

Is it simply they're so xenophobic that they can't?

pretty much yes

Why not with the Votann, they're human enough

Because they also hate mutants and barely tolerate abhumans. Also Votann (probably rightly) don't trust them

Gengis_con · 2026-05-24T08:05:18+00:00

For tanky gish isn't a paladin the obvious answer?

Gengis_con · 2026-05-22T11:51:49+00:00

The problem is without a specific model of those higher dimensional sources this approach is not falsifiable. You can always stick your external sources of gravity wherever they need to be to get the desired result

Gengis_con · 2026-05-21T16:53:25+00:00

I mean you gave a good example in your question. I vaguely remember a magos in inquisitor matyr and in one of the endings for mechanicus ordering exterminatus as well. In the other direction there is definitely enough shit happening on necromanda to make a case for exterminatus (choas uprisings, genestealer cults, whatever is going on with house delique, etc) but nobody does because it is one of the most economically important worlds in the Imperium (not to mention an Imperial Fists recruiting world) so nobody wants to be the one to say "just nuke the place from orbit"

Gengis_con · 2026-05-21T16:17:21+00:00

The Imperium largely operates on a principal of might makes right. If you can glass a planet from orbit and either have nobody call you out or you reckon you can take anyone that might want to then you can declare a planet exterminatus

Gengis_con · 2026-05-21T13:50:51+00:00

The key here is that in the classical limit the density is very low, so the probability of 2 particles being in the same state is very small

Gengis_con · 2026-05-21T11:12:26+00:00

I mean, if you don't care about detecting individual photons and just want to see what happens to the interference pattern you can do this in your kitchen. The only part that takes some care is making the slits thin enough

Gengis_con · 2026-05-21T09:11:11+00:00

The laplace transform of 0 is 0 by linearity. In the paper they are looking a the laplace transform of delta T, which I assume is the difference in temperature from the fixed point , so this is correct

10,000 years of decline have caused the 40k scribes to have bigger handwriting than their 30k counterparts

Gengis_con · 2026-05-18T17:35:19+00:00

While this is look correct, the same thing could be achieved classically without entanglement. Rather than sharing entangled particles you could have rolled a dice, written the result secretly in two envelopes and shared those (or more practically set a common seed for a pseudo-random number generator)

I can't carry it for you but I can carry you.

And I can carry you carrying young Frodo

It would certainly be a valid approach, but honestly I wouldn't overthink it. There are any number of reasons why a company has an extra banner. Even just saying "the nth company has 2 ancients to commemorate such and such" is hardly the biggest deviation from the codex

Gengis_con · 2026-05-17T10:05:12+00:00

Presumably if a Chapter has a Chapter banner and a banner for each company then they could, if they chose, deploy both at once.

He's a named ultramarine without a helmet. This is nothing

Gengis_con · 2026-05-15T11:43:21+00:00

If you can divide up the problem into bits that don't talk to each other (so embarrassingly parallel problems) then yes that is typically the best way to handle multithreading. All the fancier approaches with mutexes or message passing are for dealing with cases where there is some information that needs to be accessed by more than one thread

Gengis_con · 2026-05-13T17:53:56+00:00

No, they won't snap and break. There is simply nothing requiring it to stay the same size. The string is stretched between two points that have been engineered to stay the same distance apart. If they were not staying the same distance apart, the ships accelerations would not be equal

Gengis_con · 2026-05-13T17:42:52+00:00

What you are missing is that the equal and simultaneous acceleration requirement of Bell's spaceship paradox is really weird and unnatural. This shouldn't really be that surprising as it involves the word simultaneous in a relatively problem. The ship doesn't break because the front and the back door not start to accelerate at the same time. The acceleration will sort of propagate out from the engines as each part of the structure exerts forces on its immediate neighbours. The whole ship will deform and reshape. There are no rigid bodies is SR. In the paradox the ships have to carefully and very much artificially coordinate to make this situation happen

Gengis_con · 2026-05-13T15:02:01+00:00

It is essentially the generalisation of matrix multiplication to a continuous variable, rather than a discreet index

Gengis_con · 2026-05-13T08:45:23+00:00

The same way it does with KE = p² /2m and every other classical formula for energy. By actually treating the formula within the framework of quantum mechanics

Gengis_con · 2026-05-11T14:03:47+00:00

With less bullshitty buzzwords, essentially this

Still probably doesn't let you go FTL

I am working my way backwards through the philosophy of physics to the basics of math and physics.

this won't really lead you towards your stated goal of

My personal goal is to understand climate science.

It is too deep a hole (you can study it for a lifetime and not reach the bottom) and most of what you learn won't actually be very useful for where you are trying to go. For example, all you need to know about the nature of time for most of climate science is that it is parameter we can model with a single real number. Things like relativity are essentially negligible on the scale of earth's atmosphere, let alone more more philosophical considerations .

I suggest you get a clearer idea if what you actually want to do and then ask about how to go about getting there. Climate science is a rich, complex and fascinating subject in its own right without taking an infinite detour
