>The same hormones don't make the penis bigger when taken in adulthood
What's the reason for this? If we could figure this out and inhibit whatever mechanism is in play, wouldn't there be an easy fix for increasing penis size?

I suppose he means “waves” are more “real” than “particles”. Even if you look at particles, they’re not clearly defined “billiard balls” but rather they too are kind of smeared out. So the word “particle” itself confuses the reaity of the thing. Everything is waves.

My mother was pestering me about going to therapy because i am 24 year jobless loser. Suddenly i lost control over my emotions and started yelling really loud while crying. Mother dont want to talk to me, which is not surprising, myself i have trouble understanding my reaction. What the fuck is wrong with me? This is so famous nervous breakdown? Is this depression?

Objectively speaking why do we need psychopathic/sociopathic/ASPD people in the gene pool?

Think about it:
> 20% of prison inmates are psychopaths, 50% of the violent crimes are from psychopaths
>There's historic evidence that a single individual in a position of power can cause extreme damage to those hierarchically below them (not to say to society as a whole): Hitler, Stalin, Enron CEO, Jim Jones, Saddam Hussein, etc.
> Not all psychopaths are serial-killers, but all serial killers are psychopaths
> The consequences of having no remorse, makes them unable to learn adequate behaviours from their mistakes or by punishment, yielding therapy
> Psychopaths given counseling are 10% more likely to engage in antisocial behaviour.

Interesting, let's say for the sake of the argument that UN decides to make critical thinking a must to have in basic education. They probably reach to a similar conclusion than me at some point in their lives, because it's not about apathy in the sense of "I guess if they aren't doing nothing to me I can safely not care", but rather in the fact that we're currently in a time where technology (such as nuclear power, internet, ai, etc.) can really pose a threat to ourselves by falling in the wrong hands. And while we could setup legal frameworks to avoid certain things, in the end, with enough work they can always be circumvented.

I ask this question because it deeply troubles me that it seems highly rational and pragmatic to just, vanish them from future generations.

In understanding the computational model of the human brain, this term often gets invoked. The way I crudely understand it is that the sum of constituents of computer logic form an entity that is allowed to control the directive of further computing to proceed unlike conventional computing where instructions are merely punched in. But I have a feeling that even in conventional computing, there is some degree of reflexive computing, non-linear equations like 3-body problem come to mind. How can one achieve this and am I understanding this correctly?

i guess the word i'm looking for is "dimensionless". it just means "an avogadro's number of". it has no dimension, it's just a number. kilograms have the dimension of mass, seconds the dimension of time, meters the dimension of length. mol is dimensionless, it is just a number of something. you could for example have an avogadro's number of meters which would be equivalent to a mol of meters. or a mol of picoseconds would be 19,000 years. real units don't work like that. you can't have a kilogram of seconds

Yeah it's kind of an un-unit, but it is far more useful than most other units, at least for chemistry. I mean, the other units?

SI is for industrial practicality primarily, and used in science incidentally. That's why you have pants-on-head retarded units like candela as a base unit, which is based on human psychosensory perception.

>>11210227 gives a good perspective on historical roots.

>>11210261
it's like making "dozen" a fundamental unit. We already have a unit for counting; it's called 1. btw, the new definition of mol breaks the traditional interpretation of the number of atoms in 1g of C12, as in this is no longer true with the new units

IMHO, base units should describe length, mass, time, and charge (in all its varieties like electric and color charge. mass is a type of gravitational charge, but since it is also inertial mass, it probably should be given it's own unit). Candela, mol, and kelvin are fucking imbecilic units.

>>11210339
>kelvin
>imbeciliic unit
bullshit. Of course the unit's scale is arbitrary as it is cancelled out by [math]k_b[/math], but similar things are true for other units as well. For example, energy and time can be chosen unitless, because they form fourier pairs. Does that mean they should be unitless? Similarly, it makes no sense for length and time to have different units, because they are converted into one another freely using lorenz boosts.

from the little i've seen online, it seems like it's either difficult or impossible to find an exact value for a general case, so instead of trying to find an integral, it would be better to use some constructive solid geometry library to find the solid of intersection, and find the volume like that.
