So exactly how will quantum computing change software, hardware and our IT society in general?
Like, how will quantum computers be better than current computers in terms of how advanced the software can be, and what applications will it have? Sorry if my question is retarded, obviously I'm not much of a /sci/entist
Ive seen this question alot and every time the answer has been, 'they wont be better in general, you'll never play crysis on a quantum computer, they'll be good for some very specific kinds of computing tasks' I dont really understand why, but thats come up every time ive seen it
>>7657787 Theoretically quantum computers would be able to utilize non-deterministic algorithms to allow infinitely-parallel processing in order to solve an algorithm. You give it an algorithm (again, this is all still theoretical) and it will solve that algorithm with every infinite possible range of variables and give you only the range of variables that were able to pass through the algorithm.
While this kind of infinitely-parallel processing sounds like it would be wonderful for all the parallel graphics rendering... Comment too long. Click here to view the full text.
>>7657806 Exactly. After Shor proposed his algorithm, there has been a flurry of papers how to use quantum computers for quantum chemistry. There is simply not enough concentrated effort on quantum algorithms yet to see what is and isn't possible. A first step would be to build a scalable computer and execute simple calculations on it, just like how classical computers started.
>You have two pieces of string that each take one hour to burn. They can burn from either end and you don't know what their lengths are or even if they are of equal length. They also burn at variable rates, that is, they burn fast for some periods and slower for others. Using just a lit match and these two strings, how could measure out 15 minutes of time?
>>7657707 For the sake of the riddle, you are a castaway on some island filled with faggots, and these faggots show up every 16 minutes to do nasty things to your butthole, so you should hide preferably one minute before they show up.
>>7657498 >would you work for a defense contractor?
Because humans have been killing each other since time immemorial, if I didn't work that job someone else would and if no one worked that job then we'd just go back to killing each other with large bits of rock and pointy sticks.
>>7657492 OP here. I probably should have put down my secondary question. What cards would be on the board and each hand if this were true? I've thought about this for a while and thought "maybe 4chan can do the work for me" so I went here.
Is there a decent hologram technique that can create volume with some technique ? The problem with holograms is that they can only use light that has to be casted on a surface except for mid-air ionization technique which is shit.
Is there a way to block or occlude the light coming in mid-air to fake volume ? What are the latest the most modern hologram techniques ?
I'm not an expert on the subject by any means so forgive me if there are any flaws in my physics.
That being said I have considered the subject and I have formed a hypothesis that it might be able to create holograms using a technique wherein lasers are scattered at various points in 3d space by way of a non uniform electric field.
The basic idea is that a focused laser grid is projected into a region, and by very very precise manipulation of a magnetic field within that space you can cause the lasers to defocus at chosen points causing light scattering... Comment too long. Click here to view the full text.
>>7657082 Obviously different people are better at different things, but as a whole I would say math is harder for the average person. All people, no matter how bad at languages, can learn a language by putting in many hours of memorization and repetition. On the other hand, some people just really don't "get" math and for those select people memorizing formulas will never make them get a deep understanding of the subject-matter.

>>7656983 I don't even understand what they're trying to say.
They made an inductor with ten windings and an unspecified spacing, using Earth as a core. By what means is an electron forced out the end fast than the speed of causality? Are they implying that the wire can interact with itself via a magnetic field and therefore turn on the light faster than it would take light itself to travel ten times around the earth?
I don't understand why they would frame it that way, but be so ambiguous at the... Comment too long. Click here to view the full text.
I was going to say "I found this picture on an unmentionable website" but decided it's not worth mentioning.
Reddit made some good points in their comments. Then again, it's a science sub so it's not really the worst place to go if you're on that site. Though I feel like reddit effectively killed Slashdot and sucked up a lot of it's users.
Alright sci prove you are smart. Your friend Aristo brought cards. On each card there is a letter on one side and a number on the other side. He lays the 4 cards shown in the picture infront of you and says: If theres a vowel on one side there is an even number on the other side. How many cards do you need to flip in order to know if he is telling the truth?
>>7656954 2 "E" and "7" "E" must be checked for an even number "V" could have any number under these rules "2" could have any letter under these rules "7" must be checked for a non-vowel All this assumes "On each card there is a letter on one side and a number on the other side" is know for certain, and isn't part of "is he telling the truth?"
But the higgs, quantum tunnels into the true vacuum from our meta-stable vacuum when our vacuum decays, a considerable time after total heat death. Creating a bubble of this true vacuum that either decays instantly or expands at light speed.
Or on the edge of tiny decaying primordial black holes, which probably don't exist.
>I believe that advances in both foundational and observational physics have conspired to show us that this assumption is wrong: that each observer lives in their own unique universe, that nothing beyond its boundary is real and that we must never speak of more than one observer or universe at a time. If true, this implies a radical rethink not only of cosmology and fundamental physics but also of the nature of reality and of each observer’s place in the grand scheme of existence.
>>7656796 Solipsism is not possible to prove, and functionless even if you embrace it.
That's not to say thinking it through isn't very important, and doesn't expand your ability to consider all other avenues of thought, but nonetheless. Our observations of physics tend to be consistent between individuals.
People get real pissed, and very snotty when it comes to solipsism. It's usually because they're scared and can neither say, nor do shit about. It's there. It's gonna always... Comment too long. Click here to view the full text.
ITT: Things you do to annoy/troll undergraduates 1) Pronounce Galois Gaylouis 2) Insist that you can use prove the chain rule with cancelation of fractions 3) Handwave hard proofs, go through easy proofs with infuriating detail
>>7656787 >[Any question about fundamentals that would take me less than a minute to review] >Recall from [exact subsection/equation reference to a textbook in another course that they used 2 years ago]. I love watching them freeze up and error while considering that I'm expecting them to remember everything they learned in precise detail. The smart ones start panicking and reviewing, the rest just get depressed.
How fucked am i in math and science courses in college, if my handwriting is complete dogshit?
How much handwriting is really required in most courses? Im almost certain i have dysgraphia and non of my teachers can read my writing, some of them will automatically just give me an F on any portion of my tests that require writing.
