To pursue a career as a theoretical physicist, it is essential to major in physics at university, ideally through an integrated BS-MS program offered by IITs in India. Preparing for the IIT-JEE exam is crucial for admission, although alternative institutions like IISc Bangalore and CMI also provide excellent physics programs, with IISc admitting students through KVPY and JEE. The discussion highlights the competitive nature of these admissions and the importance of a strong foundation in mathematics for success in physics. There is a recognition that many Indian parents may not fully understand the professional research landscape, often associating physics with figures like Einstein rather than acknowledging the broader career opportunities available. For practical experience, engaging in workshops and internships at institutions like TIFR, BARC, and CSIR is recommended.
