1. Because the cost to change is more than the benefits.
2. Only ones who care are high schoolers who can't into basic conversions.

What do you mean by "official system of measurement"?
You do know the U.S. Government defines 1 inch as exactly 2.54 cm, right?
And don't forget that nearly every nation on Earth uses a mix of SI, and traditional non-metric units.
Ask a Britbong how much they weigh, and you'll have to Google "stone".
Does it hurt the butts of mathematicians that physicists often invent their own mathematics and don't really need them?

Nobody need mathematics. They are just autists playing with their decimal numbers.

Physics and mathematics have had an incredibly deep, productive, and symbiotic relationship.

How much has body augmentation and cosmetics ruined genetic selection?
Everything from lipstick to hair color, to plastic surgery is meant to hide or fix what a person looks like. Does ugliness among a genetic demographic increase over time since the partners can't tell what the other person really looks like? How about child rearing? Does plastic surgery/breast implants increase the occurrence of women with small breasts? As time goes on, does that genetic trait also interfere with the ability to feed infants?
Aren't there specific genetic markers a person unconscionably looks for that triggers them to be more attracted to someone? Aren't these markers typicality those in the same genetic pool as they are? Isn't this intended to find the most viable mate for social and genetic compatibility so that there's a better chance of fertilization, less of a chance of miscarriage, and the offspring will thrive?

Been a while since I've done audio stuff.
It's probably just filtering out noise in the ground plane. Audio stuff is sensitive like that.

filtering high frequency perturbations.
I think it's called decoupling capacitor in english
Where can one find an advance copy of the movie Vaxxed, or a digital copy?
I heard it has been shown at a couple of festivals, surely someone booted it.

This is a scientifically valid film, not entertainment
>>
>>8098864
First off, if you wanted to discuss the movie, you could've just created a topic directly aimed at anti-vaxxing, not a sneaky OP, this isn't /tv/
Second of all:
>anti-vaxxer film
>vaccines cause autism
>scientifically valid
lol
I saw that thread yesterday on /tv/, and I wanted to bash my head on my desk from the scientific illiteracy. People claiming vaccines haven't had any effect when they were used, claims that only adults should take vaccines because giving it to kids "fucks them up". There's lots of stupid shit going on around here that /sci/ laughs at. Anti-vaxxing is a movement that is genuinely dangerous. Fuck this movie and fuck anti-vaxxers for allowing old diseases to flare up once again.
Now go back to >>>/tv/ and find the rest of the dumbass /pol/acks and Trump supporter lurkers to agree with you on the "menace" that is vaccines. You don't belong on a science forum.

I'm interested in the idea of brain plasticity, because I'm a piece of shit and there are a lot of things i want to change about my personality. The way I understand it, performing an action "digs grooves" and creates a habit, so over time confident or disciplined activities change your brain to the point you are a naturally confident or disciplined person. I have a few questions about this:
1) Is my understanding of brain plasticity fundamentally correct, even if it's pop-sci tier?
2) Currently I'm using a lot a of drugs, stimulants and beta blockers, to get school stuff done and better in social situations. Are the habits Im building using these drugs going to stick with me long term, even after I stop using them?
3) Where can I learn more about this without getting a degree in neuroscience? Are there any reasonably scientific self help books on the subject?

Plasticity is basically neurons making new connections with other neurons. Supply and demand can make this happen. Look, what I'm trying to say is you won't find any quick fix to being a piece of shit. Work hard, Study hard and be disciplined. We're all gonna make it bro.

why would i do that when i have the great scientific minds of 4chan?
but seriously there is little chance an ordinary doctor would know anything about this

Don't learn too much of it, but yes, it's a great tool.
It's a shitty language, but it has lots of packages and makes graphing pretty easy once you get used to the awful language conventions.
You should maybe spend <10hours learning basics. Maybe even less. Then pick up the rest as you go.
>>
>>8098767
Horrid language but very large and useful code base.
Worth knowing and using, not really worth creating new things in.
Note that some of the great R stuff there (like most of the nonlinear regression packages) is actually just a wrapping for FORTRAN implementations.

how do forces work? we know an electron and a proton attract each other but how does work exactly? what is transmitting that force exactly?

ok since we have cloning for animals, why don't scientists clone the food we eat, for an example, a box of mini wheats before it hits shelves, in the factory we clone the entire factory full of mini wheats then give it too the stores, we keep giving the stores cloned food so we can keep a endless supply.

we sort of do this already. Ever notice how bananas don't have any seeds? Well how do bananas without seeds reproduce if they don't have seeds? The answer is we clone em'. We cut off a little bit of a banana tree, and like plant it in some stuff to like make it grow into a new tree man. Every banana tree is like practically identical.

1. If they mention the cross product, ask what to do if considering a 4-dimensional system? (Cross product only works in a limited number of dimensions)
2. If they say a function is continuous ask with respect to what topologies?
3. If they say a sequence converges ask with respect to what topology?

Every time they try to skip a trivial step in a proof, raise your hand and insist they explain it because you don't understand

So, I've a question about astronomy, or quantum mechanics, I guess. Given the incredible size of our own universe, would it even be plausible for there to be theoretical billions of them, with some being exact replicas of our very own?

Yes. This has been recognized for some time now.

There is a probability that you are as you are. It's small but it exists. Call this P(you). The expected amount of you's to exist is the amount of events multiplied by the P(you).
In an infinite universe with an infinite amount of stuff which is clustered in a way that's similar to our local region and the stuff obeys the same rules of physics as our own. Let each cluster of stuff be an event with the possibility of you existing then doing crude math you can see that:
P(you) * #(events) = P(you)*infinity = infinity
thus you would expect an infinite amount of copies of yourself. You can refine what the criteria for P(you) are but shit's the same.
Since our observable universe is finite in size anything outside this finite region is merely speculation.

You bunch of idiots don't think this is absurd because you don't even know what watts and potency is.

Wrong you faggot. Joule is a unity of energy. Watts is a unity of potency, that is, of energy dissipated in certain amount of time. Joules per second.

How far away do you think we are from computers being at a point we can create our own universes in them with the detail, scale and AI on the same scale as our own?
Do you think it will ever be possible?
