What are the key topics in modern physics and engineering?

How did you find PF?

I found this forum while doing random search on Google.

I studied physics about 30 years ago. I am interested machine design, mechatronics, innovation.
I am computer programmer and MCU programmer.

Welcome to PF!

Thanks a lot. I am here for a special physics problem. I hope one can help me.

If it's a schoolwork question (even for self-study), start a new thread in the Homework Help forums and show your best efforts to work on the problem. You will get great tutorial help at PF as long as you show your own efforts first.

If it's a general technical question or a problem from your work, start a thread in the appropriate technical forum and again, show what you have done so far to try to figure out the problem. It is also helpful to post links to what you have been reading to try to figure it out.

Enjoy PF!

Thank you forr you detailed reply. Not a schoolwork question. In fact it is a question I know answer, I asked to one mechanical engineer, an aircraft engineer, a physicist, an associate professor and professor on mechanical engineering. They all replied same as me. I think we may forget something, because of that I need other experienced eyes and brains.

By the way, the problem is about circular motion, very very simple. Today or tomorrow I will write it here detailed.

Thanks.

We have seen your new thread, and it is under Mentor review (so it may not be visible in the general forums at the moment)... This process can take up to a day.

Thanks, I was afraid of that I violated a rule.

Hello Berkeman,
So sorry I could not reply yesterday night, I was busy with an electronic project.

Thanks a lot for your approval of my thread.
