2018-12-18 19:51:05 UTC

I mean, literally, how do you do that?

2018-12-18 19:51:17 UTC

Do you randomly search books and articles on random topics?

2018-12-18 19:51:37 UTC

You need to study the periodic table, mainly.

2018-12-18 19:52:01 UTC

And get a good textbook

2018-12-18 19:52:06 UTC

Then start from the beginning

2018-12-18 19:52:09 UTC

Like, to know what are symbols of different elements and what is their order?

2018-12-18 19:52:16 UTC

Mhm

2018-12-18 19:52:20 UTC

That's the first step

2018-12-18 19:52:21 UTC

What textbook?

2018-12-18 19:52:33 UTC

That's the boring step I'd gladly skip

2018-12-18 19:52:44 UTC

I already know too much of a period table

2018-12-18 19:52:49 UTC

I would recommend any one in your native language

2018-12-18 19:53:03 UTC

What, why

2018-12-18 19:53:33 UTC

The concepts are a bit annoying to have to read through with English, no?

2018-12-18 19:53:56 UTC

I don't really get what you mean know

2018-12-18 19:54:58 UTC

If you have no preference nbd

2018-12-18 19:55:11 UTC

Might be getting sick ree

2018-12-18 19:55:17 UTC

But basically

2018-12-18 19:55:29 UTC

What happened?

2018-12-18 19:55:32 UTC

The first thing you want to learn is a bit of background

2018-12-18 19:55:42 UTC

Starting on the subatomic level

2018-12-18 19:55:49 UTC

With electrons mostly

2018-12-18 19:56:19 UTC

since that's most of the size of an atom and where the interesting stuff happens.

2018-12-18 19:56:29 UTC

And then you move up from there

2018-12-18 19:56:29 UTC

Oh, like valence electrons and shit

2018-12-18 19:56:42 UTC

Size not mass btw*

2018-12-18 19:56:47 UTC

I know that all atoms want to have either 2 or 8 valence electrons

2018-12-18 19:57:15 UTC

Yeah. They just want to occupy the lowest energy state possible

2018-12-18 19:57:27 UTC

And that's when they have a neutral charge

2018-12-18 19:57:51 UTC

I will probably add "learning chemistry" somewhere on my to-do list

2018-12-18 19:57:55 UTC

So they will give up an electron or two or gain one if that's what it takes to be neutral

2018-12-18 19:58:15 UTC

But it sounds like something requiring putting some effort

2018-12-18 19:58:27 UTC

Yeah, and they share these electrons with other atoms

2018-12-18 19:58:38 UTC

Which is why if you go across the table by group number, there are certain atoms that will usually show up in nature with a certain charge.

2018-12-18 19:58:48 UTC

Which I've posted before.

2018-12-18 19:59:02 UTC

But I will post again cuz it's cool

2018-12-18 19:59:28 UTC

I really used to like chemistry back in midschool

2018-12-18 19:59:40 UTC

I sometimes miss these classes

2018-12-18 19:59:57 UTC

I mean, I still have math and physics

2018-12-18 20:00:06 UTC

But with chemistry it would be just perfect

2018-12-18 20:02:20 UTC

I sucked at chemistry in HS

2018-12-18 20:02:35 UTC

It was interesting without the math parts I struggled with.

2018-12-18 20:02:42 UTC

Although I would probably do a lot better now.

2018-12-18 20:02:50 UTC

2018-12-18 20:02:56 UTC

Math is easy

2018-12-18 20:03:06 UTC

Most of it is boring

2018-12-18 20:03:22 UTC

But at least it's easy and you don't have to put any effort into that

2018-12-18 20:03:31 UTC

All the metals have a variable charge and readily give up electrons to become cations

2018-12-18 20:03:41 UTC

So you don't have to really keep track of them

2018-12-18 20:04:38 UTC

But the main group elements all have a charge they will take on to stabilize the atom.

2018-12-18 20:04:46 UTC

I got straight 50s in math until I was 20 and went back to college to upgrade my shitty high school grades.

2018-12-18 20:05:02 UTC

Once I learned programming, math was ezpz

2018-12-18 20:05:24 UTC

Which was dumb that programming made more sense to me than math did and I ended up working backwards to git gud at math

2018-12-18 20:05:26 UTC

What does "50s" mean?

2018-12-18 20:05:30 UTC

Sometimes with math all it takes is just taking off from it and then relearning it.

2018-12-18 20:05:30 UTC

50/100

2018-12-18 20:05:33 UTC

Like a percentage scale?

2018-12-18 20:05:34 UTC

Oh

2018-12-18 20:05:35 UTC

Ok

2018-12-18 20:05:37 UTC

A 50 is the minimum passing grade

2018-12-18 20:05:56 UTC

It should be here too tbh

2018-12-18 20:06:10 UTC

I literally learn math on tests

2018-12-18 20:07:17 UTC

It's like
Okay, I don't know a shit about all this "combinatorics" thing, but I'll figure it out, right?

2018-12-18 20:07:28 UTC

And it always works for me

2018-12-18 20:08:35 UTC

Well that's good

2018-12-18 20:08:45 UTC

But yeah learning about matter is fun.

2018-12-18 20:09:05 UTC

And you end up learning about how it interacts with the fundamental forces and vice versa

2018-12-18 20:09:38 UTC

Which is invaluable knowledge if you're OCD like me or just curious about the nature of the universe ^^

2018-12-18 20:10:10 UTC

Universe is a horrible place tbh

2018-12-18 20:10:20 UTC

Its cold dark and ugly.

2018-12-18 20:10:31 UTC

But matter is cool

2018-12-18 20:10:38 UTC

But there's starts to light it up

2018-12-18 20:10:41 UTC

Well, isn't matter a part of the universe?

2018-12-18 20:10:48 UTC

Like, quite an essential one

2018-12-18 20:10:56 UTC

Definitely.

2018-12-18 20:10:58 UTC

The downside is that those stars emite huge amounts of radiation and will boil you alive in space without a suit.

2018-12-18 20:11:05 UTC

I meant how it interacts with the rest of the universe.

2018-12-18 20:11:10 UTC

What a shitty way to die.

2018-12-18 20:11:16 UTC

Oh, okay, I meant the "universe" in a broader sense

2018-12-18 20:11:21 UTC

Like, including Earth

2018-12-18 20:11:23 UTC

And shiet

2018-12-18 20:11:26 UTC

You turn into solid ice on one side, and the side of you facing the star boils.

2018-12-18 20:11:40 UTC

Also your lungs get fuckin pressed flat.

2018-12-18 20:11:52 UTC

Yeah you don't want to get pulled into something that dense.

2018-12-18 20:12:30 UTC

Which is why I don't get why humans keep trying to make crappy little spaceships made of metal.

2018-12-18 20:12:50 UTC

News flash people.... you live in a spaceship thats a giant rock.

2018-12-18 20:13:37 UTC

Which generates its own magnetic field that keeps you from burning up if a flare from the Sun goes off (Which it does often)

2018-12-18 20:13:47 UTC

Well the metal is lighter than a rock with a dope magnetic field.

2018-12-18 20:13:59 UTC

And getting it up to space requires it to be light

2018-12-18 20:14:02 UTC

At the moment anyways.

2018-12-18 20:14:06 UTC

true

2018-12-18 20:14:19 UTC

Surely, someday, we will discover a better method of propulsion other than chemical rockets.

2018-12-18 20:15:14 UTC

I mean. Hope so? Not really? Seems like a Waste of money.

2018-12-18 20:15:31 UTC

Everything is a waste of money

2018-12-18 20:15:45 UTC

It's like if you're implying that something humans do is not pointless

2018-12-18 20:15:51 UTC

Everything people do is a waste of money

2018-12-18 20:16:06 UTC

I agree.

2018-12-18 20:16:29 UTC

Some people want to close themselves or other people in small metal cages and send them far away from Earth

2018-12-18 20:16:36 UTC

But that's okay, they have a goal

2018-12-18 20:16:49 UTC

People need the goal in they're life that they can pursue
