Can a engineer become physicist?

Yes… you can become a physicist starting from no degree at all, an engineering degree would only help. How hard it is depends on the specifics of the kind of engineer you are. It is also possible, though iffy, to get a job as a physicist without a physics degree… an engineering degree is the usual substitute.

Does ISRO hire physicist?

ISRO recruit candidates with PhD in Astronomy, Physics and Mathematics along with engineers in disciplines such as mechanical, electrical, electronics and computer science.

Can I become an automobile engineer with a physics degree?

As for ‘can’ vs. ‘cannot’ part of the question, the answer has to be ‘yes’, but it depends on who the degree owner is, what kind of engineer is, and how the person works on it. A person with a physics degree who spends all his time cooking cannot become an automobile engineer.

Is it better to be a physicist or a chemical engineer?

As a physicist, you’re going to have a big advantage coming in over, say, a chemist. Most of chemical engineering is physics: fluid dynamics and heat/mass transfer especially. However, it’s at a much lower level of abstraction than you’re probably uses to.

Can I do a PhD in physics with a master’s degree?

Yes, you can. The analytical and mathematical abilities that an advanced degree in physics can give you can be used pretty much in any discipline. Take me for example, I hold a Master’s degree in Physics, a PhD in Biophysics, and am now spending my time documenting electrical engineering procedures.

Is it possible to be an engineer without an engineering degree?

Yes, yes, and yes. See all those millions of so-called engineers out there who call themselves engineers because they have an engineering degree? Well, many of them do not know the first thing about engineering. All they have is a piece of paper from a university. If you want to be an engineer, idolize Steve Wozniac.
