AI Thread Summary
A 17-year-old African American male is grappling with his academic future after struggling with a low GPA and shifting interests from science to history, and finally to physics, which he has developed a passion for. Despite recognizing the need for hard work to pursue a career in physics, he admits to not putting in the necessary effort, leading to concerns about his potential. Forum participants emphasize the importance of taking responsibility for his education and suggest community college as a viable path to improve his academic standing. They stress that success in physics requires a solid understanding of math and recommend resources like Khan Academy and specific textbooks to reinforce his learning. The discussion highlights that while it's never too late to turn things around, commitment and consistent effort are crucial for achieving academic goals.

Okay, I am a 17 year old African American Male, i have had many changes in what i want to major in when i get to college, First i started with being a scientist, then a chemist but then i actually took the class chemistry (Regents Course) and it blew my mind and frankly i hated it. Then i realized i really enjoy history, so i thought of being a historian. Then when i reached 11th grade i took Physics for the first time, and my eyes were open to a new world, i fell in-love with it immediately..but right now my grades are really messed up. i Probably have less than a 2.0 GPA, its not that i can't do the work...i just don't its shameful honestly, but can you guys tell me what you think about this? Can things turn around for me to actually bring my dream to fruition?

Then you can't be a physicist. Simple as that. Being a physicist takes work - a lot of it.

Nope. You can wait forever for things to turn around by themselves. You can turn them around, though.
 
When i say can things turn that's what i mean, if i work at it...and with me not doing the work, I am starting to realize that's pretty childish and I am starting to do my work and things
 
Thank you for the honesty
 
So you don't want to put in any work. Fine. What do you think you'll ever going to accomplish in this life?? EVERYTHING takes work, not only being a physicist.
If you think your own future is not important enough to put in any work, then by all means, keep doing what you are doing.
 
To counter some of the ''tough love'' responses here, if you want to ''reinvent'' yourself in a way, you need to go to community college, it is your second chance to be able to go to a university. All you need to go to community college is have a GED or High school diploma. You can take all your lower division courses at a community college before transferring, but this time you will have to work hard and earn good grades, so you aren't doomed quite yet.

Quite true. It's never too late. But don't start in a community college unless you're prepared to work hard and give yourself 100%.

the "tough love" is what i need to be honest, but i AM starting to change, I've probably been Googles #1 fan for the past couple of weeks, I am just looking for different feedback from people who like physics too

I know the road ahead is going to be difficult, but i enjoy physics so i don't mind the hard work

Then stop googling and wasting time on the internet. Start working and studying.

Yes, khan academy is very good. You should keep using that!

But only watching videos is not enough. You need to make A LOT of exercises if you really want to grasp the material. So get yourself a decent textbook and start working exercises. If you combine khan academy and a regular textbook, then you can get very far.

Do you have any textbooks in mind?

Physics, a textbook that can cover basic things (so i can brush up) and more advanced things

Before you start physics, I suggest you work on your math first. If you don't know math extremely well, then you shouldn't even think about starting in physics.

A book I always tend to recommend (because it is just THAT good) is "basic mathematics" by Serge Lang. It covers about everything you need to know about high school mathematics. Work that book until you understand everything and until you can work every exercise. Lang's book is not easy however, so you might want to complement it with other sources such as Khan academy.

After that, you can start with studying calculus. I like the book "practical analysis in one variable" by Estep. It contains a lot of information on calculus and it is suitable for a high-schooler. You might want to learn from a more rigorous book later (such as Spivak or Apostol), but they might be overkill for now.

After that, you're ready to start physics. The book by Halliday and Resnick is a good place to start (but only if you know calculus). You don't need to know calculus to start physics, you can also work with an algebra-based physics book, but I don't recommend this.

The books I recommend are books you should really WORK through. Just reading them and skimming theml a bit is not sufficient. You need to understand every sentence and every word, you need to work the exercises and you need to ask a lot of questions. You should aim for a COMPLETE understanding, not a superficial one.

I know you need to be good at Math, I am good from Algebra-Trigonometry...Trig. i could use more brushing up but thank you for all your help, ill be sure to look into those books

You should be able to solve these questions very fast:

1) Factor x^3-x^2+2x-2.

2) Solve

\left\{\begin{array}{c} 2x+y=4\\ 6x-2y=3\end{array}\right.

3) Prove

(\cos(x)-\sin(x))^2=1-\sin(2x)

4) I'm looking at a tree from a distance. The visual angle between the bottom of the tree and the top of the tree is 10°. I step 2m forwards. The visual angle has now increased until 15°. How high is the tree?

Unless you can solve all these fairly fast, you need more practice.

OhKay let me rephrase, i need ALOT of brushing up

you're on winter break right? perfect time to study :)

Count me in the it's-never-too-late-but-you're-gonna-have-to-start-working-for-realz-now category.

I had the worst study habits in high school. I did practically no work at all. In fact, I missed 34 days of school my senior year of high school; I never went to school unless I had an exam or something. I was just about as lazy as you could be (though I still graduated valedictorian...go figure).

So I get to college, and I wasn't at all prepared for the amount of work that was expected of me. Suddenly, just being smart wasn't good enough. I had to actually study and WORK, something I had never done before. It was a very tough adjustment for me, almost traumatizing. I got far more B's (and even a C...whoops) those first few semesters than I care to admit.

By my junior year, I had finally developed good study and work habits; my grades improved as my study habits improved and I started getting A's. I ultimately graduated with a final GPA just over 3.5, which is relatively low for a prospective grad student.

I'm in a good physics graduate program now, but I got in by the skin of my teeth (I can only assume my LOR writers must have the literary skills of Hemingway or Joyce, 'cause my transcript wasn't stellar). I did very well this past semester (my first semester in grad school), even getting one of the very rare A's that was passed out in an especially difficult course (~30 students in the class and several B-minuses and C's were given...B-minus or below is "failure" by grad school standards). I don't let a day go by where I'm not doing some physics. Even during the current winter break, I'm working on E&M daily.

Best of luck to you.

Basic math skills are more important - if you want to study physics at the university level, you'll eventually need to take SATs, and good scores on that can help out subtantially.
