Any recent news involving quantum computing?
>>16945820Anyone?
Holy kek this /sqt/ is on life support
>>16946435Don't worry, it'll be up and going right after spring break.
Can someone do my homework, it's a geogebra question thing making a construction for the Riemann integrals, thanks y'all <3
>>16947913ask ai
>>16947913If you can construct the diagram like this, that could work out alright in Geogebra
>>16949655no...
>>16949655>muh aikys
has qc surpassed the 40 qubit number or whatever it was 5 years ago? I mean actual qubits that can be entangled and used, not some meme marketing number.
>>16953175ask ai
>>16953180ai is bought and paid for by qc companies and their not useful qubit counts

What is the most elegant "triangle inequality check"?
>>16957721s = (a + b + c)/2If (s – a)*(s – b)*(s – c) > 0, then the side lengths form a triangle.Otherwise they don't.
>>16957721Basically the same as >>16957863, but just check if (a+b-c)(a-b+c)(-a+b+c) > 0, cause triangle equality says all 3 terms are positive and it isn't possible for 2 to be negative. No need to consider area
>>16944314I want to make a borax mixture, as explained here: https://alsnetbiz.com/homeimprovement/homemade.html (the "equivalent to Bora-Care". instructions under "Prepare the concentrate")I plan on using propylene glycol, and heating the mix in an electric kettle made of glass and/or a ceramic pot.is this propylene glycol as safe as the instructions say? is the borates mix safe enough to reuse the pot, or should I only keep it for chemical stuff in the future?
>>16958715>propylene glycolthey put it in food and cosmedic products, and is a laxative
>>16958904yeah, that's why I chose to use it instead of the ethylene.still, I want to be as cautious as possible. that's why I'm asking.what about the borax and boric acid? also wonder about the gases. at 260°F I can imagine some nasty things might form and fly from the mix?
>>16958170>(a+b-c)(a-b+c)(-a+b+c)= (a + b – c)*(a + c – b)*(b + c – a) = (a + b + c – 2*c)*(a + b + c – 2*b)*(a + b + c – 2*a) = (2*s – 2*c)*(2*s – 2*b)*(2*s – 2*a) = 2*(s – c)*2*(s – b)*2*(s – a) = 2^3*(s – a)*(s – b)*(s – c)
>>16959149This post was invisible for more than one hour. That's why I accidentally posted it a second time. It only became visible after I posted it the second time.
>>16944314>13 days>25 postsJUST
>>16958918>wonder about the gasesNo harmful gases should come off, borates will not decompose from the heat and they wont react with anything in your mixture.Dont reuse the pot for making food borates are toxic to eat keep that pot for chemistry/junk
>Le particle is in a bunch of places at once until it's measured, then it's in one placeSo how do they know that it was in a bunch of places at once before they measured it? Nobody ever actually describes the experiment, they just show you the alleged conclusion and go "ooh, spooky science!"
>>16960315Because they perform experiments. That was what the 2022 Nobel Prize was for.It's also what the Dual Slit experiment demonstrates, which is why it is brought up all the time. It's the simplest experiment that shows the particle can't be in a single place before it is measured.
>>16960337The claim of self-interference is not reducible to an empirically verifiable sequence. The label of self-interference is hyper specified to particular experimental arrangements not having anything to do with self-interference of one or more underlying elements. Consider an experiment that sets out to demonstrate a claim about an element interacting with itself. There is no means to isolate the element from the experimental apparatus or any of its partial interactions without reflexively destroying the claim of self. As such, the inductive chain does not exist and the conclusion about underlying particles or emissions is confabulation. A further paradox arises when trying to minimally fit the frame to the apparatus and experimental parameters. We don't even get to say a self-cycle is occurring by the same logic before.

What are the best books from a beginner's perspective for embedded systems and aerospace engineering, particularly astronautics?
So, if you push a long thin rod into a wormhole with a throat diameter smaller than its length sideways, what happens? Does the rod bend around the curved spacetime of the wormhole until it hits itself?

I have to design and complete a research project/paper (for Geoscience) for my major. If I'm understanding, I'll have eight weeks for design and prep, and eight weeks to complete it, with some time in between the two courses.How do I...do a research project? I swear half the time I Just try to come up with something that sounds like I can get credit for it and toss it at the wall but that's probably not a good idea for a final level assignment.
>>16961592The kinda goofy, but overall answer to this is "follow the scientific method":1. Pick a phenomenon or a problem (maybe even one that seems obvious -- a good jumping off place is "extra credit problems you may have had on tests," because that's how profs often talk about their own real research.)2. Make a hypothesis about a solution to that problem -- what do you need to test to prove if it's true or if a technique is "good"? What assumptions does that require? 3. Hit the literature & find papers and books around the topic. Use the keywords from 2. to dig -- to start, you really should use actual library tools or your textbooks to find papers etc., but Google Scholar also works. (Your school probably has a research guide for a particular field like this: https://libraries.etsu.edu/research/guides/geosciences/methods)4. You'll probably end up getting an answer to some of your idea through the literature, but there's probably a gap or someone not doing a good job explaining why or having shitty code or whatever. Bingo, there's your Thing To Do. 5. Iterate There's also a textbook, "Research Methods in Geography" that you can probably find on libgen or by searching around.
>>16961027y = –Sqrt[r^2 – x^2]Tan[θ] = dy/dx = –x/yα = π/2 – θ = ArcSec[Abs[r]/x]If r > 0 and x = 1 (which is the case), then α = ArcSec[r].Thus the acute angles are ArcSec[3], ArcSec[5], and ArcSec[7] from top to bottom.
>>16961610Thank you. I found that book. It was free for whatever reason, praise be to abdul or whoever uploaded it.
Solve Fermi’s paradox from a biologist’s point of view.
>>16961027>G = green>Y = yellow>C = cyanThat one is based on the dark blue one, on the wall.

Consider the trumpet formed by rotating the curve around e^{-ax}. A wire coils around it at some particular angle starting from x = 0. It makes an angle theta at the meridian of x = 0. What is its length at x = t?
>>16963753I meant rotating the curve of e^-ax around x axis.
>>16963753> A wire coils around it at some particular angle starting from x = 0.> It makes an angle theta at the meridian of x = 0.> What is its length at x = t?Huh?? I have no idea what you are even trying to describe.Maybe try a better picture?
