AI Thread Summary
The Special Theory of Relativity, proposed by Albert Einstein, fundamentally changed the understanding of time and space, introducing concepts such as time dilation and the relativity of simultaneity. It is crucial in physics as it reconciles the laws of mechanics with the speed of light, asserting that the laws of physics are the same for all observers regardless of their relative motion. This theory has profound implications for modern physics, influencing fields such as cosmology and quantum mechanics. Understanding it can provide insights into why the universe behaves as it does at high speeds. Exploring this topic can offer a fascinating perspective on fundamental physical principles.

I have to write a short article about a physics subject, i can pick my own subject.
Problem is i don't know any fun subject :(

I am second year physics student, university

You don't? Haven't you ever wondered 'why does this work?', or 'how did they find this formula?' or things like that? Well, this is your chance to have a closer look.

Example: How did Newton find the Law of Gravity? After all, he couldn't fly around in space, measuring forces...
 
try DEFINING TIME
 
Try Special Theory of Relativity. This shouldn't be too hard, you should be able to find a lot of general information and concepts on this matter.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
