I'm a brainlet at quantum mechanics and all, but I got super excited about it after seeing how a quantum computer should work.
Please explain me why does a "super-state" exist and why it does matter at all about a "observer" seeing the process. I like examples with cute cats like Schrodinger's Cat.

>>8718983
Schrodinger's cuck is an example of superposition. If you put a cuck in a bunker with a bomb, there is a chance that the bomb explodes or that the bomb doesn't explode (if the bomb explodes the cuck dies). You leave the cuck in that bunker and cannot see the cuck. Quantum Mechanics suggest that the cuck is in a superposition of living and dead, until you go check if it is living or dead so that the universe has to decide a definite state of either a living cuck or a dead cuck.

>>8719001
But that is to us who are not watching him from the outside. What about his vision inside? I mean, I can understand to our point as a observer, but why would this thing actually care or be in a super state? Does it mean that everything we can't watch isn't defined? We are special little beings that just decide if something is or not? Shouldn't it adopt a position even if not watched?

You see, that's all, I don't understand the observer thing in practice at all.

What do you guys think about the idea that dark energy is just an emergent phenomenon linked to the universe's tendency to increasing entropy?
The more I think about it, the more it makes sense to me. Dark energy is one of the only things in the universe that doesn't obey time symmetry. This fits perfectly to the profile of an entropic force. It could sort of act as cosmic scale brownian motion, can't it?

Is there a way to check if two graphs are isomorphic that can be automated easily (don't really care about time complexity)? I'd have loved characteristic polynomials not to be memes but they are since two non-isomorphic graphs can have the same polynomial.

I think this is what you're looking for

>don't really care about time complexity

Let G1 and G2 be graphs with n vertices.

1. Go over all the n! ways to name the vertices in G1 using the vertex names in G2.
2. With each iteration, check if G1 and G2 are identical after the naming.

I believe you can reduce this from O(n!) to O(2^n) if you use dynamic programming.

Does anyone else have a difficult time switching between two different sciences? I've only recently begun to notice it since I'm taking upper level biology and maths/chemistry courses simultaneously, but I feel like if I switch between the two in one day nothing really "sticks". I need to dedicate one day to biology and one to chemistry/maths. Anyone have any advice on how to circumvent this problem?

Wish I did, unfortunately you'll just have to power through

I am curious on why you're doing both upper level math and Chem bio.... double major?
If so, that answers your question

If not, your academic advisor is screwing you
>>
Do physics as chemistry and biology are trivial applications that can be left to the reader
>>
Yep, double major. I just find that it's very difficult to transition between mindsets. This becomes especially frustrating in upper level maths courses when I have to recall the mental steps I took to make sense of a theorem. It seems trivial when I'm looking at it one second and in the next it may as well be gibberish.

Fuck you

Freud was right about 90% of his theories but people only pay attention to the disproven ones
>>
>>8718317
Well-designed psychology research is science. The therapy side of it is mostly pseudo-scientific bullshit. Psychology is too young and the subject matter too complex for application of what we actually know to be fact. Most people only ever see the poorly designed research cause it gets all the hype, and the therapists that don't know jack, hence the feeling about psychology.

It is, but CogSci>>>>>all of the shit they took to make this a real thing like Linguistics and Psychology

Prove me wrong, you even have to learn math like a CS but less autism and more research all the time.

>Prove me wrong, you even have to learn math like a CS but less autism and more research all the time.

Maybe. I looked at my alma mater and the CogSci department only required the math need for the specialization (e.g. Discrete Math for CS specialization, Psychology Math for Psych specializations, non for philosophy, etc.).
>>
>>8718143
It's science, but it's really simple science. The methodology and experimental techniques aren't really sophisticated. Nothing can really be quantified in a theoretically meaningful way. The results that have come out of linguistics are nowhere near those of more established sciences. Another issue linguistics has is that there is little consensus. There are a few foundational issues that most people agree on, like the existence of some form of universal grammar, underlying representations in phonology, and phrase structure in syntax, but the details of the implementation of those notions can be wildly different from theory to theory. That said, yes, it is science. I think it's interesting and potentially really valuable, but we have a long way to go.
