And in each one of these research areas, of which there are even more, there are PhD students, like me, and we study incredibly narrow topics, things as narrow as a few processes or a few molecules.
و براي هر كدام از محدوده هاي پژوهشي، كه بيشتر هم هستند، دانشجويان دكترا مثل من هستند، و ما مباحث فوق العاده ريز رامطالعه ميكنيم، چیزهایی به ريزي چند فرآیند يا چند مولکول.
