I will get an IISER and I want to major in physics as it had always been my standout interest in school but obviously college physics is a whole new ball game with advanced maths and stuff so how exactly should I approach it?

How different is it and how tough was it to deal with the jump?

What are the things I need to be warned about before going into it?

I want to do PhD after this anyway so no worry about regular placements . Just need to know how strenuous and time consuming the course is

How much free time do you get, does it keep you fully occupied and do you get time for your other passions, and with health issues can one still come out on top

Did physics ever discover that one second has its particular duration, or did humans first choose the size of the second and then physics simply develop better and better ways to reproduce that same duration?

For example, the second was originally based on dividing a day into 86,400 equal parts, and later it was redefined using the cesium-133 atom. But the atomic definition was chosen to match the already existing second.

So my question is: has physics ever shown that one second must have that particular duration because of nature itself, or has it only replaced less accurate standards with more accurate ones while keeping the original human-defined duration the same?

BHAI YAAR ITNA CONFUSING HOGYA HAI koi kehra hai saleem sir se matt padho beta sbb khrab hojayega end tkk aate aate koi bolra hai mr sir se mtt padho bohot formulas krate hai merko kuch bhi smjh ni aara atp.

saleem sir ke mechanics ka one shot dekha hai m ne 8 hours wala- great

mr sir se m ne Ray optics ki hai w proper lectures- also great

please help me out man m bilkul bhi risk nai le skti ye mera last and only attempt hai.

syllabus mere haath mai hai kyuki m faaltu ke lectures 17 19 kinematics ke liye toh nahi dekhne waali 🙏🏻

I am starting IIT jam prep for 2027 . I don't know where to start from needed guidance and resources to start also should I take online batch or self-study.😭

Plz DM the resources

Hi everyone!

I'm preparing for IIT JAM 2027 (Physics).

Is anyone else preparing for the same exam? It would be great to connect, discuss doubts, share resources, and keep each other accountable.

Feel free to comment or DM me!

this will be helpful to the people wanting to study physics without doing rigorous math .

Energy is conserved because physics is symmetric in time. Momentum is conserved because physics is symmetric in space. Emmy Noether proved this in 1915 and it changed everything.

List some institutions for pursuing MSc Physics in India. There should be an ecosystem for astronomy in the institute, either through the presence of a astro faculty or/and as subject in the course. Private & public both. Do they allow dissertation from outside ?

Hi all,

I will start my BSc in Physics in around 2 months from now and I am not really sure how to use this time to my advantage. I intend to work in research after my graduation and eventually go to a good college for graduate studies.

What would you prepare if you were in my situation? Or what should I know that I wished I knew when I was a freshman?

Thanks!
