About Valentin
I am a 51 years old physicist from Romania. I received the MSc in physics (physicist engineer) in 1991 from the University of Bucuresti, Romania where I learned physics for 5 years. My GPA at graduation was 9.37 from 10.
Then I worked for 10 years as physicist in different countries in gov facilities (RO, US, DE, DK, etc). In 2000 I received a PhD in physics from the University of Bucuresti (Romania) with "Magna Cum Laude".
From my activity as a scientific researcher I have about 12 scientific articles published in renowned international physics journals.
Since 2009 I have worked as a tutor for different companies. For about 3 years I was also an academic writer with other sites.
I know very good Semiconductor Physics (Solid State Physics) and Electronics. They were my major at graduation.
I can help you easily in Mechanics, Thermodynamics, Statistical Physics, Quantum Mechanics, Electrodynamics, Relativity, Atomic Physics (and Particle Physics).
What I do not know is Optoelectronics.
I like learning new things in physics from my students and this is why I continue tutoring. You can ask me whatever physics question you have. I could have the answer to your question.
I am tutoring because I need the money. I never had sufficient money. I want to buy a home in Southern Europe, in a country where people live longer and feel safer than where I am.
I like having many friends and I learned important physics from my students.
Thank you and have a good day.
