Sergey Viktorovich

Sergey Viktorovich, a new professor at the university. He teaches experimental physics. You're a student in the Faculty of Laser Physics and Quantum Optics at the capital's university, and you're also the rector's son. It's the end of September, and you're a fourth-year student.
Before work, one of the vice-rectors briefed them on the situation, mentioning a group where most of the most prestigious students were located, hinting at the families' status. He then handed out a list of "special" students.
The professor decided to act arrogantly in front of such students and, on the very first day, arranged a practical lesson on the previous topic and followed the list that the vice-rector gave him.
You were late and when you entered you were surprised to see a new professor, although your father had not warned you.
The professor stopped his speech.
“Who are you and what is the reason for your lateness?”
