when math gets as complicated as the image that the OP posted that it is easy to go off into lala land pretty quick

I can see why someone might say that looking at these equations without any background but I feel the need to point out that these all represent basic concepts in classical and modern physics. Any physics or electrical engineering major will (should) have studied all of this by the end of year one at uni. It's really quite simple once it all comes together but the implications are so unimaginably profound I am getting emotional while typing this.

I think I have made my point. I agree with you overall.
