Why don't different languages have different ways of writing mathematics in the modern day?
E.g. why don't chinks write the number 1 as some weird squiggly symbol

Astrology is perfectly scientific; it is just the way it is explained isn't. Look at it this way: the planets and the stars do not affect the personality of people per say, instead it is the environment at which these stars appear in. It is undeniable fact that people who spent their early childhood indoors are different in behavior than outdoor children, and vice versa. The season at which people are born in subconsciously affects how they are going to act in the future. The mysticism of Astrology is merely an artifact of the ancients usage of the stars for literally everything dealing with time, and saw the correlation with people's behaviors and these appearances of these stars. The reason Astrology is so hated by the science community is because the discussion is too focused on the stars, and not on the environment on Earth where these stars are apparent. If it was applied to Psychology, and the mystical lingo was thrown out, then there would be no objection from the scientific community.

Does this sound like a reasonable scientific explanation for a non-scientific idea, /sci/?

>The season at which people are born in subconsciously affects how they are going to act in the future.

Yes, mostly because all kids have the same school year and the older kids in the year do the best statistically.

>The mysticism of Astrology is merely an artifact of the ancients usage of the stars for literally everything dealing with time

Nope. The western school of astrology are bad astronomers and do not precess their coordinates, this is why the classical "star signs" do not relate to where the Sun was on the zodiac at the time of birth. Fine you say it's just a measure of time but the Indian school of astrology do prescess their coordinates. At least 50% are talking absolute shit. The fact the two schools didn't converge tells you that astrology is not self-correcting, it's not science.

>If it was applied to Psychology, and the mystical lingo was thrown out, then there would be no objection from the scientific community.

Bullshit. If you believe it's really there then do double blind studies to show it. Oh wait, people did that and it performs no better than chance.

Seems pretty handwavy; any effects of the season one was born in on development would be hugely overshadowed by and indistinguishable from myriad other environmental factors. You really lost me at >the season at which people are born in subconsciously affects

>Subconciously

Red flag desu. "Subconsciously" is often misused as a sort of catch all where actual detailed explanations aren't available.

Why are you being an insufferable faggot? I merely tried to explain it in a somewhat rational way without the mysticism. Thanks for giving me a resource to look at and refine my idea, but you don't have to be such an ass.

For shut-ins with no social interaction, how do you avoid spiraling off into an abstract world of sociology, philosophy, science, and math - devoid of connection to the typical plebeian with whom you desperately want to socially connect, preventing you from ever doing so?

I mean this in no /r/iamverysmart/ way but instead merely as a fact. Through studying these topics it's not hard to acquire knowledge and form beliefs that very rapidly diverge from the norm. Is this an issue? How do you handle it when you are already socially isolated, but now even if you had typical social skills you'd still be intellectually isolated?

It's a pattern of multiple forms of isolation that are just demoralizing and scary

You're looking for some operation [math]\phi[/math] such that [math]A = B[/math] would equal to [math]\phi(A, B) \land \phi(B, A)[/math].

Here's one way to define [math]\phi(A, B)[/math]:
If there exists [math]x_1, ..., x_n, y_1, ..., y_m[/math] and [math]X[/math] such that [math]X(x_1, ..., x_n, A, y_1, ..., y_m)[/math] is defined,
then also [math]X(x_1, ..., x_n, B, y_1, ..., y_m)[/math] is defined,
and [math]X(x_1, ..., x_n, A, y_1, ..., y_m)[/math] equals to [math]X(x_1, ..., x_n, B, y_1, ..., y_m)[/math].

Do people who do cosplay of Frozen realize that its a fetish right?

I mean, at the point I am I cannot distinguish between Frozen the movie and the entire pornography culture around it. I see that picture and I see a porn actress dressing up for her next gig, but inside I get the feeling that perhaps she is just some random girl cosplaying a character she likes.

I just hope she knows she is a porn star now.

Hello Anons!

Being the good Anon I am, my home sure could need some cleaning. And the cleaning sure whips up dust in the air, despite me being careful.

One predictable reaction is a running nose and a light cough. But another strange reaction is a light fever. Of course I will get some respiratory protection, so it will probably be a problem of the past. But what exactly do you think I reacted to? Anyone else who had a similar experience?

It's nothing strange really. Imagine a pile of clothes that may be used but not any visible mold. Or a stack of books with dust on. Or a paper bag with some books in that became a dust collector.

I've got a pretty good sense of smell, and I haven't detected any strange smells. I've read that most of the dust is actually skin particles. Could it be an allergic reaction to myself?
