Hey lainnons. I want learn physics,chemistry by myself on uni lvl. Is that possible?Or better go to some uni,college?I want learn this for DIY in my garage

Most college textbooks are designed for self study and can be found for free online. Pick a subject and start reading. If there's any prerequisite knowledge required they'll tell you in the beginning of the book.
>Or better go to some uni,college?
Uni isn't about having access to knowledge, it's about having access to professors, like minded peers, labs etc. Personally I found that very helpful, but everyone is different.

Yes. You can self-study most things. And as with most things, you'll want to get your hands on a textbook on the subject(s).
At the beginning of most textbooks -- or at least, the ones I've had and read -- they usually have recommendations for the professor on reading order(s) and what they could be for. Keep in mind, you can just read them front to back.
Marly Krushkhova · 2022-06-03 16:57
if you get textbooks don't just read em. solve the problems, try do do related work that you can check in concert. If you hit something you can't follow / understand easily, stop, work through it, and figure it out. Good to have a contact or two that's familiar with the area you can chit chat with now and again.

this. also make sure that you've really tried your best at solving the problem independently before looking at the solution or any hints or anything else that might aid you in solving it, and then when you get stuck, try to take that aid one piece at a time, each time going back to the problem to see how that new piece of aid has helped you. (remember that you're not just learning the material, but also learning about how your own learning process works)
when you've arrived at your (fully independent or not) solution, compare it with the book or solutions manual. the idea is to see how others have solved the same problem, to help you learn others' methods of solving the problem
keep in mind that you're training your brain, so you should be keen on thinking about what people's thought processes about it are, if you can. get into people's heads and get their heads into yours, so to speak

Don't underestimate youtube as well. Aside from retired professionals and engaged hobbyists I've found the Indian "National Program for Televised Learning" (they started 20+ years ago on betamax tapes!) https://www.youtube.com/c/iit/playlists a literal treasure trove of information. It's like they have whole universitys on record, almost any subject one can imagine. You can see the same professor middle aged and old, old courses not teached anymore (but maybe still of interest...), etc. You'll have to finagle the YT-search and navigate by the playlists, but you'll figure it out. After a few hours even the accent gets mostly intelligible.

Did they deliberately make their logo as elecromystical/alchemical looking as possible or was it a happy accident?
Hiro Protagonist · 2022-06-11 00:30
For physics Feynmann's lectures are a nice course / textbook. They have simple drawings and good intuition https://www.feynmanlectures.caltech.edu/
Learning on your own should be a combination of broadly reading so that you develop an overall idea of how everything fits together and what exists, and a specific project so that you focus on details somewhere and learn what actually works. Or what I mean is, don't try to learn the details of everything at once, as you will get lost and not know what is really relevant.

I know, isn't it absolutely amazing? Also, that's only one of the universitys involved. Yes, the other logos are similar. Also, check out the intro for the videos e.g. https://www.youtube.com/watch?v=qEg3DrBe-3U... It's a different culture allright - and isn't all technology somewhat magical?

Theory: Easily possible
Experiment: Possible but costs much money

I imagine most chemical suppliers will refuse to sell to you unless you have that piece of paper signed by a university.

can you sage if you are going to speculate without experience? your comment is just discouraging but also ignorantly so, because its still possibly and easy to buy non restricted chemicals

When ur done studying, ALWAYS use safety gear. it's all soykaf and giggles until you've got boiling acid in your face.
Use glassware ment for the experiments you will be performing and get a good ventilation/fumehood. It costs a lot of money, but it's worth it if you want to do anything more than basic chemistry.
The internet can get you many chemicals. Others can be made, if you have enough time on your hands. Yields and purity won't probably be too great tho.
Arisu Mizuki · 2022-12-11 10:44

not so, certain chemicals are definitely restricted but the vast majority aren't. Some that are restricted are only for higher concentrations eg. 30%+ hydrogen peroxide. you're probably thinking of ""research chemicals"" where the fancy piece of paper is basically liability for them going 'oops we didn't know he was gonna eat the chemicals, we do not condone this behavior and it was not sold for this purpose'

>a good ventilation
good ventilation can mean just working outside for certain things. usually you know whats going to be bad and can arrange to do it outside when you need to.
>>9630
this depends so much on country its almost pointless to talk about. There's also a lot of chemicals that maybe you can't easily buy straight, but you can buy with a little bit of impurity from a pool supply store, or as drain cleaner perfectly fine.
Naomi Nascimento · 2023-03-24 01:24
alternatively: self study for a while then volunteer in a university lab. this way you get access to mentors / peers / facilities without having to sit through an entire course.
just stroke the professors ego a bit first. read some of their papers and say you think their research is unique. have some sort of idea of what you actually want to do or learn.

How do you know which textbooks are good before deciding on one to go through?
Yet Another Lainon · 2023-06-16 22:23
I'm not a chemist or physicist but I went through both courses In university. I was pretty bad at physics (wasn't super enthusiastic about calculus and the professor was a menace so I checked out) but really good at chemistry. Of course, the courses were easier since it wasn't the main focus, but I certainly learned a lot and some of it is still there... But most of it isn't. I'm sure if I still had my test papers or lab protocols on me I would struggle to understand my own writtings even though I actually tutored some of my peers on this and somewhat enjoyed the subject.
But after about a year of new subjects and neglect it's kinda gone now. So be sure you'll keep it up if you decide to start.
I'm sure I'll catch up quickly if I ever pick chemistry up again, I was naturally good at working in the lab itself getting good percentages of product mostly.
Try to avoid the Grignard reaction if you can, I always used it in my tests and professors always said this is only valid on paper and after I got to try it myself I wholeheartedly agree.
The fact that I still remember suffering with it even though I basically forgot how alcohols and ethers work says a lot. It's a pain in the ass, but very useful for synthesis on paper.

You can buy plenty of things as technical grade chemicals. there are certain red flags that will get vour raided tho, and manufacturers may have you fill out paperwork for your intended use.

A nobel prize winning physicist made a site for people that want to teach themselves physics:
https://webspace.science.uu.nl/~gadda001/goodtheorist/classmech.html
MIT open courseware has some sciences modules(With some problems to solve as well). For text books, libretexts offers open access to university textbooks.

IF this is your first time, you'll probably need to look at reviews and go on a limb and try one. If someone here can recommend a good textbook in that field, that would be much appreciated :)
and then once your done with the textbook, you can test whatever you learned on the internet or against another textbook.

A widely-used and well-regarded first chemistry textbook:
Chemistry The Central Science - Brown,LeMay,Bursten
A widely-used and well-regarded survey of physics textbook:
University Physics with Modern Physics - Young and Freedman
Or The Feynman Lectures (3 volumes) as mentioned above is also a great introduction to physics.
You will eventually also need at least
calculus: James Stewart is good enough
linear algebra: Gilbert Strang
differential equations: George Simmons
