I'm 16 and need/want a life in Physics.

[simplicity123]

I'll be completely honest with everyone..I literally know my times tables and that's it..I was trying to teach my self algebra for half an hour and I had no idea what was going on in the equation. I'm not going to school today because I can't handle the stupiedness of it just sitting in class while people swear and are always on facebook. I'm going to try and get a grip on the "easy"math first. Trig/algebra.

I'm in third year studying Maths from good uni.

I don't know my time tables(I did three years ago through). Literally I would struggle with basic subtraction now, I can't subtract now. Maths isn't arithmetic. Plus I forgot all my calculus so Maths isn't even that.

Also, go to school. You want to go to uni so you have to do it. If you are sitting in class bring a sheet of problems you can do and then do it.

 

[An Open Mind]

Well, it's not that long. I started Maths at 18 and now 22. In 2 years time will be going for PhD and probably could do all the fancy Maths that is supposedly hard that theoretical physicist do.

2 years of college + 4 years of uni. About 6 years, which isn't long. That's even assuming OP has social life. If he got rid of his social life and only studied I think he could do it in three years.

Also, the link only applies to cranks. Some people are crazy and could never do science because they have stupid theories. Don't know why everyone is assuming OP is a crank.

This is so sad what I'm about to say, but since I moved 3 schools and have lost contact with all my friends, I go to TAFE now and all the people there and mindless zombies smoking swearing rude people. I sit in class waiting till 4:30 then go home and play some xbox..I don't have a social life anymore I have my few friends I go over there houses once a month..I can't waste anymore of my life I just sound pethetic I'm getting off here now and attempting some trig.

Go to school. School isn't socializing with friends, if you have no friends at school that would be optimal. As that would mean you can focus on work.

What level of education are you? Also, don't do trig. Learn algebra first.

P.S. I only have friends at uni. Only then about 5 people at uni are my friends.

I have a man that I look up to my "mentor" and I just had a chat with him on the phone and he said I would be best starting with algebra, and I shouldn't beat my self up and get annoyed because I don't understand it, because know one has explained it to you yet.
I'm in grade 11, live in Australia - Queesland.

How does 3 squared ( with the little 2 up the top ) = 9?

I just learned about the order of operations!

Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

I'm proberly doing the easyest sums ever but It's algebra and I'm understanding it!

How does 3 squared ( with the little 2 up the top ) = 9?

3 times 3 is 9...

 

[elfmotat]

How does 3 squared ( with the little 2 up the top ) = 9?

3¹ = 3
3² = 3*3 = 9
3³ = 3*3*3 = 27
3⁴ = 3*3*3*3 = 81

and so on.

It works the same way with any number:

2² = 2*2 = 4
2³ = 2*2*2 = 8

etc.

There are a couple khan academy videos on it:

Where are you learning?

Seriously, download the book I linked you to and read that. It starts with fractions and then if you finish it you will know how to do matrices.

When I was 18 I spent a couple of month working through it and when I finished my algebra was better than the teacher who was teaching me the Maths to pass college so I can go on to uni. Read the book I linked you to on page 4.

Great feeling, isn't it ?

 

[stonecoldgen]

Id say be ahead of all the other 16 year olds

go to AP calculus, physics, chemistry and statistics

read ahead the lectures, so that when you get to class you already knowbut in general just be ahead of everyone, learn lots of calculus and physics on your own, and this may sound dumb, but playing chess (as well as being in a physics course) improove your reasoning
and about the youtube essay, I am not sure about that...but it might be interesting

and it is great you are learning a lot of that stuff
EDIT: OMFG, i read the thread, seriously, you sound more like a sci-fi writer than a theoritcal physicist, but if do want to be in science, learn the trig and the alg fast, you might even end up doing a little bit of introductory calculus

 

[romsofia]

Straight up, WHAT! I'll try and understand it though, so the x is the digit you are trying to find? Wait omg there's 2 x's wait then..what does the 2 mean uh I'm going to be here for days.

Ok Hm..the little 2 is the thing that is inportant I'm guessing..wait urgh could you please explain it a little more, like what those digits mean?

X is a variable which means it can be ANY number. The {^2} means you multiply the number by itself EX: {y=x^{2}+x} and if we plug say, 2 into it we get {y=2^{2}+2} which would be equal to 6 (since 2² is equal to 4).

My teacher said today if in 10 minutes you've made no progress on a problem, then go ask for help!

Good luck.

What the hell? He's 16, having friends and socializing is an important part of school. Having no friends and focusing completely on self -studying will only have detrimental effects in the long run.

An Open Mind,

Please do not take my post as an offense to you. I would strongly consider setting back your goals for the moment. Not forever, as I firmly believe that everyone has the capacity to gain and understand anything, as long as it's presented in a clear and concise way. If you're truly determined to study theoretical physics, I will be your biggest fan and most avid supporter.

The absolute best thing for you to do is catch up. Not just in your math, but your reading and writing skills as well, if what you've posted on this forum is an accurate representation of them in the real world. NO ONE can take away your education, whether it be math, science or reading. I cannot stress how important it is to enhance your most basic skills, as they always, ALWAYS lead to a better quality of life and better job prospects.

Your desire to self-study already puts you ahead of so many people. The best thing you can do is continue to watch the videos on Khan Academy if your public school education is not providing you with the results you wish. Build up your algebra and trig, as they are the key to understanding higher math, and thus higher physics.

Math really is a beautiful thing. I hope you see the beauty of it as well :)

My writing skills is worse than his and I'm studying Maths at uni now. There has been dyslexics Physicists, Einstein being the most famous. His Maths skills aren't even that bad. The biggest hurdle to get around Maths is anxiety.

What are you talking about? You're a math major, at a university, who can't subtract. What's with this sudden rash of people with less than ten posts making nonsensical claims.

No, your writing is definitely better than his. And there's no butts about it, if he's having trouble with variables, and just learned PEMDAS, he is far behind on a track to be a physicist. Not saying anxiety isn't something to do with it though.

 

[An Open Mind]

Open mind, what math class are you currently enrolled in now or will be enrolled in?

Prevocational Math. Basically the teacher sits there. Everyone talks and walks out whenever they want. I used to be in a good math class in grade 8 but since then I never wanted to go to school and I hated math, For some odd reason I love learning and I love learning math the most. Sooner or later I will get out of this hellish school and into a better class.

Well, your arithmetic ability goes down if you don't practice it. Again, I have none because I don't need it. Funny you said that when Grothendieck didn't know 57 is not a prime, and he was the best mathematician ever.

It won't take him that long to learn it. PEMDAS isn't that simple hence the stupid trolling with
48÷2(9+3) = 2 or 288?

I can write neat when I'm trying to, and my reading is fine but I don't do a lot of it lol :p. However I have stuttered for for ages..I've tryed everything speaking slow, taking deep breaths and thinking about the word before I say it, but that's not really what you were saying :l Nevermind. Thanks I hope you come back to my thread so we can talk some more :].

If you want a chance of going into physics this is what you need to do. You have to for now stop watching popular science videos and stop thinking about quantum mechanics and dark holes. You need to build up your math skills if you want any chance. Physics isn't talking about pretty pictures of dark holes and nebula's using words. The language of physics is math and if you can't do math, no amount of words is going to mean anything. So what I suggest is that you first learn all of your basic algebra, solving equations, inequalities ect, then learn your basic trig functions, sin, cos, tan, sec, cos, cot and there inverses. Also learn there graphs and the trig identities basically study trig very well so that you are comfortable with it. Once you did that find a calc 1 syllabus online from a reputable university and self study that stuff till you start your 1st year in college as a physics major. If you can do that then you will have the tools you need to do physics.

No words to describe my thankfullness for your help :)

 

[wukunlin]

OP sounds a bit like me when i was around that age ( ~15ish ) except I was the other way round, good with numbers but hitting walls everytime i have to use words :)

a word of advice (assuming no one has mention something along the lines of this already):
try to stay away from specializing yourself too early on, you may be interested in theoretical physics at this stage but do try to keep up other areas of science. These days I tend to think back hoping I didn't spend so much time on the details of a specific subject. It would probably be more useful to obtain a broad range of knowledge and find links between them. I have lost count on the amount of times I appreciate the fact that I took some biology classes at high school even though I hated it. Bits and pieces of general knowledge is also useful if you suddenly changed your mind one day.

good luck

 

[enigma]

Open Mind,

You have stated that you are getting nothing out of your current curriculum. Here is a lesson I wish I had learned earlier in life: if you want things to be different for you, you must fight for it yourself. MUST. The administrators at your school have put you into the classes you are in because you, self-admittedly, didn't care about school for the last two to three years. Now you want to get onto a new (and better) path. If you don't tell anyone, they won't know.

I don't know what your homelife is like, but if you can, start there. Ask your parent or guardian to help you get moved into a better class. Next, talk to your guidance counselor at school. Tell him or her what you've told us. Write down your desires if you're nervous and bring the notes along.

Ask to set up a meeting with the guidance counselor, your current teacher maybe, and a teacher of a higher level class. The goal of this meeting will be to set discrete, measurable, attainable goals that will enable everyone to be confident you will be able to succeed if you move up.

Make sure everyone knows that you are aware that you are behind, but also make clear that you WANT to put in the time to right your course.

Look at Penguino's 'suicide and hungry' post in GD. Teachers want to teach kids who want to learn. That's why they went into the field in the first place! If you show the maturity to admit you're behind and couple it with the drive to fix it, you WILL get more help than you could possibly expect.

My last suggestion which applies to your outlook and how it applies to the situation you're in and how to fix it. When you're asking how to get righted, stop badmouthing the class and the teacher. You're in the "bad" class because YOU didn't care, not because the school or the teachers are bad. The teacher probably has given up trying to teach kids who don't care. He is just a person who likely doesn't like the situation he's in any more than you do. If you treat them like you're worthy of respect by treating them with respect, you may even find an unexpected ally. Put yourself in his shoes: if you're stuck teaching brats who don't give a damn and unexpectedly one of them actually comes to ask for help, would YOU want to help if you could? I'd bet you'd be the first person in years who he has taught who showed any interest at all. He'll go home and tell his wife he had a great day because he may have someone he can actually HELP!

Math is best learned sequentially. Learning random little scraps of algebra or calculus is useless. You need to start with basic prealgebra.

 

[MissSilvy]

First: No youtube, no popular science, no black holes. Your understanding isn't even close to sufficient to begin to seriously ponder these concepts and at this point it would just clutter up your mind with falsehoods since you have no filter to distinguish lunacy from actual facts.

Second: Read more textbooks, do more math.

Finally: For god's sake, don't start coming up with your own theories on singularities or black holes or string theory. To start making worthwhile guesses in such esotheric theoretical fields, you need the solidest foundation in modern physics that you can get. Not F=ma; Lagrangians, Maxwell's laws, quantum mechanics, special relativity, general relativity, high energy, condensed matter, and a bunch of other little fields that will take years to learn.


Note that when someone says 'know special relativity', they don't mean watch a Youtube video or read some book. If you can't do and understand the math and problems that go with a concept, you don't know it. Period.

Can we have a sticky and a policy for these types of threads? There are at LEAST five new ones a week and its getting tedious to read the exact same answers to the exact same situation multiple times per thread.

Correct.

Again, I have none because I don't need it.

Ok, what area of math are you interested in? I'd say that at the very least we did some sort of shuffling of indices that required me to know the mechanics of subtraction and addition in my mathematical logic and algebra courses.

Funny you said that when Grothendieck didn't know 57 is not a prime, and he was the best mathematician ever.

Funny you think that Grothendeick would have any trouble whatsoever solving "55-22 = ?", even more funny that you think it's appropriate to compare yourself to Grothendieck; unless you have his powers of abstraction, not being able to think concretely is not an asset. I flatly do not believe that it is possible that you could not solve "55-22 =?" and are a math major, no matter if you play with structural proof theory or with toposes or what have you.

This is essential, while it's good to think about these things, you -will- become a crackpot if you start to take your own ideas seriously without a -lot- of formal background.As she said, you do not know physics if you don't fully understand the mathematics behind it. The ideas have too many subtleties to understand without embedding in precise mathematical language, you will start making incorrect leaps of intuition if you start reasoning about these things without a solid basis for doing so.
