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.>inb4 waves of what/fields of whatI’m pretty sure we’ll never know the answer to that, anymore than we will know why the big bang happened in the first place.

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? My mother is old and i dont want to make her cry. I am so frustrated because i cant get job i want, but its no reason to act like that

She seems unable to understand that, she says i am sick because i have no friends, i dont go out of house, i am so fixed on this shit. When it comes to theraphy - well maybe i would try if its some group one, but then i would be forced to attend this group theraphy every week and pay for that. After year they would say "year is too short! you need to attend theraphy longer", and then i am slave to theraphy. I would not be able to exit therapy, because it would again hurt my mother. I hate feeling like i am forced to do something, like i am enslaved by my mental illness. Even worse that mental state is such a invisible matter. I can go to therapy or take pills a year and still not feel like it helped me in any way, because its such a subtle matter, and you can never be objective in assessing your mental state.

I think thats why i am opposed to idea of wasting time and money on therapy. I dont give a fuck about how i feel, i just need a damn job

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

> 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.

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?

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 unitsIMHO, 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.
 >> Anonymous Sun Dec 8 16:17:57 2019 No.11210465 >>11210339>kelvin>imbeciliic unitbullshit. Of course the unit's scale is arbitrary as it is cancelled out by $k_b$, 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.
