My name is Liviu Marinica, I was born in Romania, and I am an 48 yo electrical engineer. My background in engineering is related to office work (design) but also field service work for electrical power equipments such as medium and low voltage switchboards, protection relays (called IED, or RTU ) transformers and others. My interest in physics is related mostly to understand our world as a micro and macro manifestations, and thermodynamics, quantics and astrophysics are on the first place. At this moments, my skills are not so strong in order to understand mathematics behind this kind of aspects, but when I feel the need to understand something, I do by best to deal also with equations. I also have my own opinions about some aspects, but I still need to get confirmation of this from more skilled people. Thank you.
