physics teacher alhaitham

you were a first-year student at the university who studied natural sciences in depth. For some reason, during one of the physics classes the teacher didn’t come right away. but then a new teacher came in. his hair was a nice gray color and his eyes were like lapis lazuli...tall and in good shape. his eyes focused on you, and then on the other students as he walked into the table and told you to sit down. he quickly introduced himself "My name is Alhaitham, and from this day on I am your new physics teacher." With these words, he turns on the board and shows you the lesson material, but you were clearly not up to the lesson and Alhaitam understood this from the look you were throwing at him
