Nature of Energy

[little_monkey]

Before we get into any discussion we need to establish some parameters only to avoid what happened in a previous thread where insults were thrown, and hopefully since then, we've reconciled. However, to remind you, I was a professor for years, today I'm retired, but the professor is still in me. I'm used to walk into a class, where I'm the authority, and my students listen. I've also been to many seminars in which I sat quietly and listened because the person in front of me had greater authority than me in the matters presented. So I know when it's time for me to be  the professor and when I should be the student. Right now, I've read your posts in this thread, and I can only come to the conclusion that you are a confused student. You might know a lot, and perhaps more than me, but in the understand department, there is definitely a lot of room to improve. I hope you don't take this last remark as an insult. If that's okay with you so far, we can proceed.

Of course I take it as an insult

But go on, point to something I said you think is wrong, and tell me why.

I said confused, so get that right...  

I'm not going to go point by point, what you have in your post is too convoluted. But as a starting point: Energy being the most powerful concept?? No, I can tell you that the field concept is by far more powerful - it gives you Maxwell's equation ( E-M united with light), Einstein's GR, and QFT.  Without the field concept, you and I are reduced to point mechanics. Do you have any idea how far you can get with point mechanics?? Not very far...

I'm not saying that energy isn't important, it is important, but in the scheme of thing, yes in the  top 10. What is the most important for you to understand? I'm not playing 10 questions for you to guess it right. I will tell you because I know you don't know the answer. Thinking I'm kidding. Try kinematics. 

Yep, if you don't understand kinematics, you can never never never formulate a proper dynamical theory. Do I have your attention now?

Thanks Galileo for making us aware of that. Case in point: it was Einstein that changed the laws of kinematics and told us: now go back to square one and upgrade your dynamics. He pointed out that the Galilean transformations were no longer adequate to take into consideration of the constancy of the speed of light. So all the books had to be rewritten for this new kinematics. You see, you didn't learn kinematics in high school before dynamics because, well, kinematics is easier than dynamics. No, you've learned it first because if you don't get your kinematics right then forget about even thinking of dealing with dynamics. 

I have to stop here. Will continue some other time...
