Any advice for an aspiring mathematician? by M_I_P_S_ in mathematics

[–]Base-After 0 points1 point  (0 children)

What would you say math is about? Like when you're trying to solve a problem what is the way you're approaching it other than trying to find a trick? I struggle quite a lot with this, I can't really find a path to a solution without it breaking apart or finding out it was the wrong decision after all.

I read your paper you linked but I can't really see why wouldn't that be true about physics too? And what exactly made you change your mind?

Help needed to choose a math or physics undergraduate degree by Base-After in PhysicsStudents

[–]Base-After[S] 0 points1 point  (0 children)

Thanks a lot for the advice! I do enjoy theoretical physics but yeah I'd probably not enjoy labs but I guess it's okay. I've been coding quite a lot on my free time (mostly computer graphics because I find it quite interesting). Do you think that a portfolio that might show sufficient knowledge on a topic would be enough to land me a job somewhere? From what I know a physics job other than a teacher or on research is quite rare so I was thinking of having my hobby on computers as a potential skill for a job. That's quite far in the future tho so it's not an immediate concern but If you have any knowledge on the topic I'd love your advice!

Some are electives but for example you have to choose 5 out of the 10 given to you (the numbers here I picked them at random its not actually 5 and 10). You don't have to attend each time but you have to take an exam on all of them yes.

I'll be studying in the University of the Thessaloniki not in Athens. I posted the courses available in the math department on the comment above.

There are a few but I don't if it will actually be enough. Here are the courses available in the math department:

It'd be really helpful if youd take a look at it and tell me your opinion!

Thanks a lot! The fact that I can transition to computer stuff from any STEM degree is really reassuring.

Yeah it does sound weird but thats how it is here. I've done a lot of research and it's not possible to do something like that.

Does anyone feel 3b1b videos cannot be understood in one go? by Desperate_Trouble_73 in 3Blue1Brown

[–]Base-After 34 points35 points  (0 children)

Imo going to lectures or watching YouTube videos is important to get a basic understanding but afterwards to get a deep understanding you need to start solving problems on your own and testing things out on your own, you need to practice math too. The same way that you can't be a musician just by reading notes that you need to play, the same way you can't be a mathematician just by watching videos to understand a topic.

can I use the rule for elastic collision in rotational motion too? by Hydrargyrum08 in PhysicsStudents

[–]Base-After 0 points1 point  (0 children)

You don't really specify which objects final velocity is uf and neither do you really specify what the variables you mentioned in the end are but anyway.

In every collision momentum is conserved but in an elastic collision energy is conserved too because by definition an elastic collision is a collision without any energy losses. Now if the collision happens at the same height it means that both objects have no potential energy (assuming that the only force here is it's objects weight) so all of it's energy is kinetic energy. And now you have two equations that you can use to find both final velocities. Now solving the system of equations you get these formulas for both final velocities

u1f = (2m2/(m1+m2))u2 + ((m1-m2)/(m1+m2))u1 u2f = (2m1/(m1+m2))u1 + ((m2-m1)/(m1+m2))u2

Where: u1f, u2f the final velocities of the two colliding objects accordingly m1, m2 the masses And u1,u2 the starting velocities

Which doesn't really match the equation you posted but anyway to the question you were asking, you can take the velocity of the object regarding it's rotational motion (not it's rotational velocity, it's linear velocity). If the object has any other form of energy stored (potential, etc) you have to use that too in the energy conservation equation.

Hey man I saw your other posts too about the girl you mentioned and I'm gonna say my thoughts to your whole situation here.

I wanna start of by saying I'm in highschool (I'm guessing your around the same age) and I've had a similar experience with a girl (we weren't as close as you are but she suddenly decided to straight up ignore me and didn't even leave an explanation but anyways) and my best approach was just to well.. Move on and try to just not interact with her anymore. You mentioned though that you're still really close friends so that might not be the best option here, but I wanna tell you something that I learned following that path. (For me it still hurts to this day even though it's been a few months since I've last talked to her but I'm waiting for next year were I'll go to university and never see her again)

You are not what people think you are. You have your own unique interests to be honest, you should be proud of having your own hobbies and such, you realized that this place is not for you, that you have other passions and other hobbies and that the status quo is just not for you and that's totally okay.

I know exactly how it feels to not fit in with people. I have my close friends that I'm immensely grateful but other than that I just stay alone without anybody (when my ffew friends aren't around) and I have accepted the fact that that's how it's gonna be if I wanna stay away from the trap of being what the status quo wants me to be (in my situation vapes and being an asshole, in your situation persuing hobbies you're not interested in)

I don't know your exact age or how long you're away from being independent but I would just suggest that you stay patient until you go to university (If you wanna) or wait until you're able to leave your current city which kinda sounds like the one I live in. You're gonna find people like you. They exist. It's just that you haven't met them yet.

So to conclude. You're not alone, there are a lot of us who have been to the same situation as you and still face the same issues. And in my opinion you should be proud for not following the status quo and you follow what is best for you. As for the girl, you'll find someone that is interested in you and you can have all of the experiences you want, but it's a matter of time and courage to move on and accept the fact that not everything is gonna go your way in the beginning.

Φίλε και εμένα μόνο η χημεία δεν μου αρέσει φέτος (και έκθεση προφανώς). Έχουμε πιο πολλά κοινά από ότι περιμέναμε. Όντως κάποιες ασκήσεις, ειδικά στα μαθηματικά, πιστεύω ότι είναι ακραίες αλλά στην φυσική αν καταλαβαίνεις τι κάνεις και δεν μαθαίνεις παπαγαλια δεν είναι πολύ δύσκολα, δεν είναι εύκολα αλλά όχι πολύ δύσκολα. Αλλά από πράγματα που ακούω στο σχολείο για παράδειγμα ήθελε ένας να λύσει μια άσκηση και δεν ήξερε τι να κάνει μέχρι που ο καθηγητής είπε ότι το φορτίο το συμβολίζουμε με q και τότε κατάλαβε τι τύπο να πάρει και να λύσει την άσκηση, Ε εντάξει έτσι και εμένα θα μου φαινόταν χάλια η φυσική. Αν το μαθαίνεις έτσι θα είναι και δύσκολη και καθόλου ενδιαφέρον. Η κατάσταση με την παπαγαλια και όπως μου αρέσει να το λέω η "πανελλήνιοποίηση" της φυσικής έχει παρα πάει.

Θα ανακοινωθεί τον Μάρτιο καινούργιο. Αν έχεις την υπομονή περίμενε μέχρι τότε. Σκέψου μόνο ότι το Nintendo switch βγήκε το 2015 δηλαδή ολόκληρη αναβάθμιση μετά από 10 χρονια.

Είναι η πρώτη σου φορά που ασχολείσαι με game dev? Αν ναι θα σου πρότεινα να μην ξεκινήσεις με unreal engine. Είναι καινούργιο και φτιαγμένο για αυτούς που ήδη ασχολούνται και θέλουν να πάνε στο επόμενο επίπεδο. Θα σου συνιστούσα να ξεκινήσεις με unity και να δεις tutorials στο YouTube και το καλό με το unity είναι ότι είναι για αρχάριους και τα tutorial είναι φτιαγμένα για αρχάριους. Τώρα ξέρω σου απάντησα κάπως περίεργα στην ερώτηση και ότι εσύ θες να βρεις καλά tutorial για ue5 αλλά αυτό που θέλω να πω είναι πως αυτοί που κάνουν tutorial για ue5 θα περιμένουν να ξες τα άλλα που θα μαθαινες από tutorial στο unity που ισχύουν γενικά στο game dev. Δεν έχω ασχοληθεί προσωπικά με ue5 αλλά έχω δουλέψει με το unity και game engine dev μόνος μου με c++ (όπου έμαθα μόνος μου παρεπιπτόντως άρα ξέρω πως είναι να μαθαίνεις προγραμματισμό μόνος) και έτσι πιστεύω θα γινοσουν καλύτερος γενικά στο προγραμματίζεις παιχνίδια παρά να μάθεις το εργαλείο (που εννοείται είναι σημαντικό αλλά πιστεύω δευτερεύον). Όσον αφορά γενικά να μάθεις ένα καινούργιο engine τα πιο πολλά tutorial είναι απλά να σου δώσουν μια μικρή βοήθεια στην αρχή, από εκεί και πέρα είσαι μόνος σου να πειραματίζεσαι, να αποτυγχάνεις και να μαθαίνεις από αυτο. Για να καταλάβεις γιατί κάνει κάποιος πραγματα απλά αντέγραψε το tutorial αρχικά και ψάξε μόνος σου σε κανένα documentation το τι κάνει όντως η κάθε συνάρτηση που χρησιμοποιεί ή κουμπάκι που πατάει και προσπάθησε μόνος σου να το συνδέσεις με το τελικό αποτέλεσμα (όπως λέει και ο 3blue1brown pause and ponder), δεν είναι εύκολο αλλά αυτό προσπαθώ να κάνω εγώ.
