why doesn't he just use a y combinator? is he stupid?
am I retarded?
I think I might be because I don't know what the fuck it's doinghttps://www.wolframalpha.com/input?i=1+*+(1%25-0)
I knew the Android calculator did this, but I didn't know Wolfram Alpha does too.
Because who the fuck uses % sign?Even in a fucking excel you put 0.01 for 1% and just format it to be shown as %.
>>16384984I use % in Excel all the time. Even in formulas.
>>16383905>>16383915looks like y(+-)x% gives right associative y*(+-)0.0x so for example100(-4% + 5%)100 -4.2%-4.2whereas100 -1%-1so it wouldn't be equal

How did this all begin? How does something like this even have a beginning, because in order for it to begin, there must have been a space for it to exist to begin with.I'm so confused how the existence of physical matter was created.
>>16383280>It's clearly something that science can't explain and probably never will.Math can though, 0!=.9...
>>16384128>Imagine a static fractal that describes all of existence/reality and nonexistence/unreality across all of infinity, every energy state, all of time and space, in some hyperdimensional fashion.Why don't you just draw/animate some imagery if you are such a master visualizer?

>>16382188>random fluctuations causes the universe..Why isn't the universe undergoing greater rapid expansion now?Isn't there even more of those random fluctuations happening now than was previously?why isn't every every single random fluctuation right now spewing forth another universe full of shit existing?
>>16384236I was merely trying to bring the idea of infinitely repeating structures across.Something that is described by a very simply mathematical construct, which exists as a consequence of inexistence having no causal laws, and contains every possible energy state in an organized manner.Of course this is not an actual thing, it's unreal, a pseudo-object outside of our measurable reality, that is simply useful at explaining why nature has structure and consistency at a fundamental level - something beneath the universe.
I'm wrapping up my physics undergrad. I took a liking towards statistical mechanics and thermodynamics early on and now at 23 I had to go and pick a thesis project, so I did.Long story short, I've never been good at programming, nor had I ever been interested in it but I had to come up with a bit of code to "solve" a really nasty system of coupled partial differential equations, something I've never been shown how to actually do in any of my classes yet most non experimental physicists do day after day. I get the whole argument that a code may help give insights into the guts of what's really happening but I see this as more of a crutch than anything else.I feel like simulations have very little to contribute in the creative aspects of sound reasoning and new models. Sure, they help you visualize a process, sure, some may help engineers make things that won't break by allowing them to look at the finer details, free from analytical approximations, but I've rarely heard of a computer simulation bridging a gap in easly applicable theorization the way only human intuition can.The main results from my thesis come from analytical methods (anything from optimization theory to dynamical system theory)to solve the system of equations after diluting its difficulty with opportunistic approximations. The code seems to be there just because it's neat, not because I can get anything intelligible from it, generally speaking.Is it always the same with computational physics?
>>16383779It's not that hard, use google. Yes, you must cooooooode to be a physicist. It's extremely useful even if you don't do it much. Even if you're the world's most hardcore mathematical physicist, some code is extremely useful to test conjectures, try out examples, produce figures etc. Most types of physicists code at least weekly if not daily, unless they are totally subservient lab monkeys.
>>163837791. Being able to code is extremely useful.2. As a physics undergrad you must figure that shit out.3. Yes, it is a litmus test for retards.
>>16383779If you’re a theorist, you’ll constantly run into problems that can’t be solved analytically. So you need to simulate things.If you’re an experimentalist, you’ll constantly have data acquisition and analysis you’ll want to automate.Both of these require coding.

Will this kind of nuclear industrial heating offer a significant competitive advantage to the Chinese petrochemical industry? Or will it make no difference?
>>16384623Well if you want to elaborate on "the point" as you call it, then just post the listing prices for the heat sources and there you go. You can compare the offers at hand and choose the cheaper option.
>>16384627There are no "listing prices" to compare with.To mention just some problems:* A Hualong-1 reactor is said to cost about 2.5$/W to build. However, that is for electrical output. How much will it cost for thermal output? It is about 33% efficient when producing electricity, so it would cost about 0.8$/W for thermal output if all thermal output could be harvested. However I don't know how much of the thermal output can be harvested. Also, I don't know what the operating cost is.* I have no idea what a HTR-PM reactor is likely to cost to build or to operate. Only a twin FOAK unit has been built so far, and to my knowledge they haven't disclosed the cost.* How much heat energy will be lost when transferred from the NPP to the location of use? It is several kilometers distance. I don't know.* For the operation of a petrochemical plant, how much of a cost is the fuel, compared to other expenses such as feedstock, spare parts and salaries? I don't know.* One alternative for heating is natural gas. However, natural gas is not a unified market. Natural gas prices vary greatly across regions depending on what pipeline network they are connected to, and LNG prices can vary greatly from customer to customer depending on what kind of contract the customer has signed. Are they buying on the spot market? Or are have they signed a long term contract? There is no simple "listing price" for natural gas.* Nuclear industrial heating is not common. There are a few examples, such as a small fraction of the output from Gösgen NPP being used for a cardboard factory. However, to my knowledge, there are not many existing examples to compare with, and certainly none of this scale.Informed speculation is necessary, and I am not informed enough.
>>16384638Some other issues* How expensive will this >>16384554 elaborate system of heat exchangers be, that heats the steam twice and provides steam at three different pressure/temperature combinations? A normal NPP does not have that.* How much will it add to the cost that the turbines, generators, transformers, transmission lines, etc, of the NPP will operate below capacity for much of the time?* How much heat above 480C is needed by a petrochemical plant? The Xuwei NPP only provides steam up to 480C.Etc
>>16384523Heating is the biggest reason why "le renewables + batteries" aren't enough and why nuclear power is necessary for net zero.Nuclear power is an excellent source of 24/7 process heat. Wind and photovoltaics produce exactly as much power for heat as they do for electricity, because the main way to get useful heat from them is through resistance heating. Nuclear power plants can produce 2-3 times as much power when used for heat rather than electricity, meaning the cost is potentially 1/3-1/2 as much. Also, you don't need expensive electric transmission infrastructure, because you can usually build the reactor where the heat is needed.Nuclear power is also potentially the best way to decarbonize district heating, assuming you can build reactors that are safe enough to place near towns, and which are cheap enough to turn off half the year, or which can alternate efficiently between generating heat during the winter or generating electricity for air conditioner peak use during the summer. In China's case, they have good candidates for those purposes, in the form of DHR400 and ACP100.
>>16384523Whatever. China's already mauling everyone else in the chemical industry anyway.
>1 is not a prime because it is inconvenient nigga what about 2π? fucking hypocrite
>>16375001>he doesn't know about τNgmi
>>16381966No, it would be transcendental.
>>16381122isnt that important in cryptography?
>>16384875NTA but cryptography is only a salient concern to terrorists and pedophiles. If the multiplicative identity were considered a prime, then every other number would be nonprime, so the property itself would be useless and retarded. It's that simple.

Is it theoretically possible that the black hole will evaporate completely through Hawking radiation during the spaghettification process? What would happen with item after it?
>>16379019I have experience with stretching cm wide black holes. What changes when they're bigger? What do they smell like?
>>16379008A blackhole is just a whirlpool in space. Don't overthink it, everything works in the same way.
>>16384847>A blackhole is just a whirlpool in space.Its a border, not a whirlpoolEver wondered as a kid (or dumb adult) what would it be to reach the end of the universe, if there was a wall? Well a black hole horizon is a universe wall.Which is interesting because it would mean that space can have holes, like swiss cheeseBut such holes would imply a change in the topology of space, because a hole isnt just created by stretching, but by tearing and reconnecting>pencil though folded paper.jpg
>>16379572>From the pov of an object what will happenIt will get ripped apart from the gravitational forces before it even reaches the event horizon>but the hole will evoparate before annihilation from pov of the objectNo, it won't, if you were to fly inside a black hole and not die you would not see anything, as all the light entering from the outside would just instantly shoot to the middle, all you would see are periodic bright flashes.
You are continously elongated so the spagettification does not kill you. Idiots of general relativity did not calculate this, so they just guessed evaporation. But maths don't work like that.
A thread for most things statistical, be it finance, engineering, business data or economics. Or whatever weird random or pseudo-random process you have that needs explaining.Many complain about this general, to say it's shit but the amount of discussion and thoughts in it have been very good. Of particular note are the engineer who works in sonar. He is a goat.
