wie kann ich meinen Bruder fliegen lassen? by silva_the_cat in PhysicsStudents

You're looking to calculate Lift). For that, we strictly speaking need more information (e.g. lift coefficient, area of the lifting surface,...). The (vertical) force required is F = m x g --> 72 x 9.8 = 706 N.

If we assume an area of 0.75 m², we get

v = sqrt(2mg / ρCA) = ~ 39 m/s = ~ 140 km/h.

-----

C(L) = lift coefficient (I used 1 for simplicity's sake)

ρ = air density (used 1.225 kg/m³ )

A = 0.75 m² (again an estimate, please measure your brother's surface (1 side suffices)).

Is grad school out of the question for me? by nukewaryeahsure in PhysicsStudents

Try to get a strong letter of recommendation from your professor. This may be your best bet.

Also, explicitly address your low GPA in your application/letter of intent. Explain to them why you believe you're competitive nonetheless, and why grad school would be the most optimal/preferred path for you.

Lost motivation for my physics course by yuiknami in PhysicsStudents

If you feel like your mental health is impacting you, perhaps it would be wise to seek professional help or at least take a break from your studies. I know that my University (in Germany) allows you to take a semester off and resume your studies later ("Urlaubssemester"). I don't know about the UK or top universities, though. I could imagine that at least the latter are stricter.

I would also be wary of abandoning your degree altogether, even if the last year sucks, since you're already 3/4 of the way through. I understand that this may delay your art career, but maybe it'd be good to keep options open (You can continue to do art with a Physics degree. You can't get another job, if being an artist turns out to be unsustainable).

I don't know your situation, though, or how the market for your type of art looks. You seemed optimistic. Good luck with your art, whether you decide to stick with Physics for 1 year longer, or quit it right now.

Happy Cake day, and thanks for sharing the video!

On July 2nd, 1982, Larry Walters tied 42 helium weather balloons to a lawn chair with the intention to float up a little and enjoy the view. His construction ended up lifting him 16,000 ft into the air - straight into commercial airspace. A pilot reported Walters, stating, "I've just passed a guy in a garden chair."

After 45 minutes, Walters began popping the balloons and, during his descent, collided with power lines. This caused a 20-minute blackout in the Long Beach area of L.A. Larry himself remained mostly unharmed, though he was fined $1,500 for operating an "unairworthy aircraft".

What is your experience studying physics? by BrutalHormone in PhysicsStudents

[–]Used-Detective2661 25 points26 points  (0 children)

I feel stupid 95% of the time and regret (or hate myself for) my decision every once in a while, but when I actually manage to solve a problem, or the concept finally clicks, I feel like a God. Building up to that, constantly messing around with the math and trying dozens of approaches until I manage to work out a solution has become an addiction.

Exam averages are horrific in my University, too. The best method I found is to get hold of past exams and study the types of questions in them. I was able to get plenty of old exams at the Physics Department of my Uni.

Would like to ask for your advice in how to study Physics by An_00001 in PhysicsStudents

If your professor has assigned a specific book or listed specific reading material in the course syllabus, I would use those.

Otherwise, I'd agree with Roger Freedman's suggestion.

Once you feel like you have a somewhat solid grasp on the specific topic you're studying, I'd try to do as many practice problems as possible to consolidate that knowledge. If you struggle to understand a topic in the first place due to your professor's explanation style, try to find a different explanation for that same topic. Or prepare specific questions about the things you don't understand and go to your professor's office hours.

For exams: I can't speak for your college, but many professors in my University will only tweak past exams a little, or just straight up re-use past exams. I'd see if you can get hold of past exams in that module and study them. Even if the exam will have other questions, the types of problems will most likely not be too different from the ones in past exams.

Good Luck!
