I’m about to graduate with a degree in mechanical engineering, but I really like calculus and I guess some topics in physics. Is it worth me doing a degree for fun? submitted by /u/Rolls_Reus_Owner [visit reddit] [comments ..read more

I need something to overcome. Give me a physics obstacle to work around/through that means more than "huh, cool". Like a needed definition of mass or charge. I loved the search for the higgs boson, it had a hard value that you could calculate. The shape of a black hole was good too. Maybe what I'm asking is if there is another hard problem that needs serious number crunching I'm not aware of I could think about/design a way to calculate. Give me hard ones and watch me struggle, I dare you. Ps, i already know about p=np problems. I need another one. submitted by /u/ConclusionPrevious79 [visit ..read more

As the title reads, how would you transform a vector from say 2D Cartesian coordinates to 2D polar coordinates for example? Within the framework of tensors, vector transformation, transformation matrix, etc. submitted by /u/Hot_Invite3850 [visit reddit] [comments ..read more

How does AP Physics C (Calculus Based) compare to University Physics I and II Calc Based at an average or above average school. Obviously MIT will be much higher level but for a standard school or above average school does Physics C even hold a candle to the University equivalent. I am talking here specifically about Freshman University Physics. submitted by /u/AlienMaster000000 [visit reddit] [comments ..read more

To me (and apparently also to smart people like Scott Aaronson), the MWI is the most reasonable approach to QM, except that it is just fundamentally difficult to accept the idea that there are superpositions of me in huge numbers, some of which could have awful fates (and some great). Is there a better way to think of this? submitted by /u/being_interesting0 [visit reddit] [comments ..read more

I'm currently the tutor of a GR course and I'd like to find an example of a manifold where the calculation of its geodesics is as simple as possible. Do you have any suggestions? submitted by /u/elperroverde_94 [visit reddit] [comments ..read more

How does this work in terms of critical frequencies and lack of stiffness? I'm having difficulty finding any sources on this. submitted by /u/IdcIdkLma [visit reddit] [comments ..read more
