I'm in my 2nd semester in the 2nd year of college and I'm very perplexed.

I'm learning a lot of physics and chemistry subjects and I can solve them using the mathematical apparatus but I just can't explain them in real life.

In chemistry I can understand a few concepts about some chemical formulas but there are some subcourses are rough like electrochemistry. In that subcourse we had to understand how cathods and anods work in a substance,how the electric field passes through a electrolyte solution,the Daniell - Jacobi pile,the Hittorf experiment,etc,most of these things weren't taught in our online courses and the teachers didn't explained what happens in most cases and all that we had were some shitty pdfs were you couldn't even cheat.

How can you explain something in the subcourse electrochemistry if you have no idea what happens in the solution?

That's like calculating the area of a lake without knowing the length and width!

In physics we learned about classical mechanics(he showed us some videos and everything became clear),E&M,electricity and thermodynamics.

The teacher did a great job explaining the classical mechanics,except thermodynamics(I remember that I was the 1st year in college and I couldn't go to his thermodynamics course because I had some issues with my college hostel) ,E&M,electricity(these courses were taught online and we had to understand these in our head with the help of some PDFS but I couldn't understand any single word)

How the heck are you supposed to understand something from some pdfs,word documents without some educational videos?

That's what happened at my university and I felt empty,with no knowledge at all!

Here are 2 examples of thermodynamics(the first 1 is with engines and the 2nd one is with the 2nd law of thermodynamics):

Don't read the parts in roumanian.

Do you use calculus in that picture? Is there any way to express these formulas in a way that someone can understand them?

What do they represent?

I remember that I used to have some greatcourses videos but they only helped me a bit and they didn't explain part by part how each formula works and what it represents.

Is engineering all about using calculus in order to derive some formulas?

That's the way I've seen it but I just can't explain some formulas in engineering.

To be honest,there was a course strength of materials which required some analitycal thinking and I had no idea what stresses,beams,etc actually do. This course gave me a lot of headache,mental stress and I had to cheat using a pdf from facebook. I just can't take it anymore when it comes to solve some problems by explaining what a force does,or how a diagram is related to that force,or that a metal can be bended and you use a formula with momentum.
