Is there any reason why, say, the newtonian constant is equal to what it is and not something else?

If it were equal to something else you would be equally mystified. That's just the way it is.
>>
>>8599204
kek these type of questions are so fucked up
I mean we emprically know them, but we have no idea why it is that way (as far as I know)

Similar to that, we don't know why exponentials in formulas are almost always integers(1,2,3) or something easy to calculate with

For example why mv^2/2 is not something like m^(345/323)v^(698/278)/2
>>
>>8599234
What are you talking about moron? Those exponents are integers because they come from integrating the definitions of certain unit measures.

hey guys. I have doctors issues.

She wants to prescribe drugs at the slightest error.

I walk in and I say I have an anxiety attack she wants to give me shit,

I walk in and I say I have sleeping problems, she wants to give me shit.

Is she testing me if I'm a druggie? Is this an easy way out for doctor, prescribing shit and ignoring the problem.

im euro btw.

What did you expect a doctor to do? They are not fucking therapists. They don't have anything else to do. They either give you drugs or they do surgery or you.

Is this the first time you go to a real doctor?
>>
>>8599016
has she been your doctor for a long time but is only showing this behaviour recently? if yes, you should be suspicious.

if no: this is quite common practice for mental health problems. throw stuff at it and keep you happy until you heal yourself automatically, a.k.a., until you're trained to emit the right amount of hormone again. just tell her you're not comfortable taking pills, they normally respond quite positively to that.

>Is this an easy way out for doctor, prescribing shit and ignoring the problem.
This.

A good doctor would offer further advice and not immediately jump to drug prescriptions.

Friendly reminder that if your are not working on artificial general intelligence or life extension, you are just a pretentious version of a short-sighted hedonist, the parallel being that you do prefer to just feel good instead of actually strategically working towards otimizing your future.

Nothing wrong with that though, the desire for a better individual comparatively godlike future is just as valid as the ones for wanking, non-applicable math or particle physics. Just wanted to give you guys some insight into your situation is all.

And yes I know that this is being smug, but it needs to be said more often before more young, smart kids waste their time not first building the tools for solving literally everything else.

Is evolutionary psychology a pseudoscience? It seems to be almost all conjecture.

>>
>>8599003

Do they make testable prediction?
>>
>>8599003
Yeah pretty much, but ir is a relatively new field (the modern definition of it at least) and there isn't really much to do other than interdisciplinary conjecturing for the most part

It does make sense I think, but I feel like the scale of it's effect and the possibility of predicting upon it is lesser than we think
>>
I don't get why evolutionary psychology is considered a pseudoscience/meme, while other subfields of psychology aren't.
What's different about it?
Honestly, it appears like people just don't like the conclusions, which render humans instinct determined animals.

- Summary: The serotonin transporter removes serotonin from the synapse, preventing an agonistic reaction. SERT has (Among others) an S allele and and L allele, and the S allele is correlated with lower SERT, and the L allele with higher SERT. S is correlated with collectivism, and L with individualism.

- Summary: A C>T polymorphism of Tyrosine hydroxylase, leading to increased dopamine synthesis, is correlated with higher IQ in schizophrenics both before and after the beginning of their illness, as well as superior retention of executive functioning.

Medically, low serotonin is correlated with violence;

>http://neuro.psychiatryonline.org/doi/pdf/10.1176/jnp.15.3.294

This suggests to me that higher levels of serotonin evolved to deal with high population densities - high serotonin pacifies a population. Medically, we dose people with SSRI's to improve their behavior. As well, supporting the hypothesis that increased dopamine synthesis should result in higher IQ, amphetamine increases dopamine by inhibiting the dopamine transporter, and this is the basis of it's use as an ADHD medication.

Females have a lower incidence of ADHD than males, and females have higher levels of dopamine;

>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2711771/

Women have more serotonin as well, and this explains their lower rates of violence. Blacks seem to have lower dopamine, and higher rates of ADHD;

>http://scottbarrykaufman.com/wp-content/uploads/2012/07/Beaver-et-al.-Dopamine.pdf

What this means is that the typical regimen of antipsychotics and SSRI's lowers IQ. I've used dopamine agonists, and I get the impression of increased intelligence under their influence. Evidence suggests that this is real, rather than just self delusion;

He's one of those guys who has made low to middling contributions to the science but has been wildly successful at cultivating his own image and popular interest in astrophysics.

In short, he's decently smart. Smart enough to make a significant scientific impact? No. Smart enough to attract people to the field and gain funding? Yes.

I need your help surviving a double major in math and computer science.

I have what I think is a good, not great grasp on CS, as I have almost ten years of experience as a senior software developer. But my mathematical skills are lacking. I just don't understand mathematics as well as I understand functions, and certain algorithms in CS. I want to pursue the math portion of my double major in order to educate myself in mathematics because I find it interesting, and essential to making myself better in my chosen field. I would be interested in assisting people smarter than I am in computability research.

Questions:

>I want to pursue the math portion of my double major in order to educate myself in mathematics

I'm going to do it, but to be frank, I am a little scared of failure. Will I be able to pass the classes if I study every night, even if I don't have some sort of idealistic understanding of mathematics?

So I'm a guy studying math at a pretty respected uni. I can give details if you want, I guess. I'm on scholarship in army ROTC and trying to do research and an internship. All I really know how to do is work hard.

I'm also not that smart. I always say that I'm smart enough to hang with the smart kids but I'll never be the best in the room.
What I've learned so far is that you should mentally/emotionally or whatever prep yourself to get C's, and learn how to work with other people. Hell, annoy them if you must. It's harder alone and impossible without a sense of realism.
>>
>>8597563
try TOCP if you make your way through
congrats! you just underestimate your potentials
>>
>>8597563
You've got 10 years in industry. So you can just coast through any CS class which isn't purely theoretical. That's a great fall back, so you really shouldn't be stressed at all.

Take 1 math class at a time. That way you don't get stressed when you have problem sets due or tests to take on the same day. You'll slowly gain confidence as the classes get harder.

As you run out of CS classes to take, shift to taking 2-3 math classes at a time to finish up your math degree.

You will absolutely be able to do math if you put in the work. Undergrad mathematics does not take special inspiration. If you're at least partially interested, you'll be fine.

Do all the problems the professor assigns, and if you can't do some, or you still don't get it, go to office hours. I was typically in the top 2/3 students in my classes and I went to pretty much every professor's office hours from time to time.
