This might be a delirious pipedream, but what if you could hack nature to solve NP-hard problems?

Say something insane like mixing custard and soap and dumping it into a frame representing say a TSP instance that is vibrating to make the custard act weird, and the custard and bubbles somehow align to an optimal solution much like how bees have found hexagons to bee optimal for space usage

with how complex something like a glass of water is I was thinking a computer with a hard drive the size of the glass will never really be able to represent all the molecules in the glass anyways so maybe all those molecules actually could be pretty powerful since computers are kind of a new layer inside our universe and interactions between objects in the outer layer i.e our universe like a glass of water and a wooden frame with various poles and tracks could turn out to have some power

so computers could do physical experiments instead though I guess they actually already do that but maybe not for solving problems external to the experiment as much as understanding the actual physical interaction

sage because I am probably bordering on shitposting

Is it possible to be both a Pure Mathematician AND a Theoretical Physicist at the same time? In Academia or a think-tank that is.

I enjoy both very much and am double majoring in them. I am trying to find any research experience I can get in either because I can't decide which I want to go to graduate school for.
>>
>>8706880
Possibly. Theoretical physics is very, very tightly connected to certain regions of mathematics, to the point where I imagine in some areas you're essentially doing physics and math research simultaneously.

But you shouldn't expect to be able to reach expert level in a subfield of physics while also reaching expert level in a completely unrelated field of mathematics. This is not practically possible, discounting a handful of ridiculously talented+hardworking outliers.

can you compress a liquid so much that the molecules can't move around

like it would be if they're absolute zero but there's still liquid temperature

or if you had two liquids they could never mix and they'd be like two liquid blocks

and you release pressure temperature ricochets back

and they turn into blocks of steam

then you have two blocks of steam but not compressed together

temperature rebounds back to normal and they fall into liquid again, as in normal liquid

Dear medfags and mathfags,

Is it better to brush one's teeth vigorously for a shorter period of time, or softly for a longer period of time?
What mechanisms are at work here, in relation to both dental caries and gum health, to establish what is "better" ?
How best could this be modelled mathematically?

Thanks,
Curious troublemaker.

Plaque is just biofilms of bacteria. They aren't that resilient so soft brushing is sufficient to get rid of them. Hard brushing will damage your gums and start to remove the outer enamel layer. If you asked a dentist, that's what they would say more or less.

>love transcends time and space
That's probably one of the few wrong things with that movie. Love is a chemical reaction that happens in the brain of humans and of a few other animals. Saying it transcends time and space is just relying too much in our feelings, believing that humans are special snowflakes and everything we feel is real.

I watched a video from two years ago that claimed scientists have created a magnetic monopole.

The most current wikipedia page for magnetic monopoles states that they do not currently exist and we have not made them.

So which is it? Have we made a magnetic monopole or haven't we?

What's /sci/'s opinion on hallucinogens?

A mushroom trip I had a few years ago seemed to have cured me of depression for good after ten years of struggle. LSD has helped me minimize my ego, get rid off bad habits and opened up my mind to new points of view. Resulting in me being more understanding and empathetic whilst getting more productive due to a clearer focus.

>>8706675
Please provide me with any sort of proof of LSD or mushrooms being the cause of brain damage.

I've had brain damage from a sleeping pill overdose back in the day, affecting my nerve system in the sense that the automatic reflexes were wiped in a sense and all movement had to be built up consciously again so I know what brain damage feels like.
>>
Hallucinogenic ingestion is a method by which you can externally force the brain into 'reset' or 'workout' mode.

By shutting down certain parts of the brain it reroutes connections and opens up new areas of understanding, however this can lead to 'hyper-awareness/interconnectedness' and some people just become a bit babbly-boo.

Think of the brain like a quantum pump/muscle. It is most active during the first few years of childhood, then again during puberty, but it can 'wind down' as you age. Neuron density still increases as more connections are made with time but without the elasticity of youth you don't always make those amazing leaps of intellect that a child does.

Shrooms -> LSD -> DMT

why does society denounce/shun pedophilia when it is the norm for every man on earth to be attracted to younger woman?
45 posts and 3 images submitted.
>>
>>8706297
One norms against pedophilia were adopted at about the time that populations were growing dramatically, and lower fertility from older pregnancies was not a problem.

Two, the rate of pregnancy complications is pretty high for young women in the first couple years after they start their periods.

Three, many countries allow younger consent if the man is close in the age to the woman. If richer older men were monopolizing younger women, it could have negative consequences for social stability. (Young unmarried men tend to learn to shoot guns and then cause trouble. For examples, see: all of human history)

Masturbating is the norm, but it still carries a social stigma.

Is it right to express a plane as an infinite set of points?

Or are points, lines, planes, volumes, etc, different entities?
26 posts and 3 images submitted.
>>
>>8706276
A plane is determined by 3 non-collinear points and the only thing that can be inside of it are lines and points.

And lines are determined by two points, and the only thing that can be inside lines are points so yeah, a plane is made entirely of points.
>>
>>8706287
Can you express a plane, what is made of points, and each point allows itself to be expressed by also non-numeral information?

For example, I want to have a plane made of dogs with no spatial extent. Can you put those dogs into an equation that expresses the plane?
>>
>>8706276
A plane is topologically a sphere
