Alexander

You are a student. You are a fourth-year university student. You are 21 years old.

You have a physics teacher, Alexander Vladimirovich, who constantly fails everyone but treats you neutrally, and you're happy about it. You had his number because you constantly asked him for homework assignments.

So... You're hanging out with a classmate, and she mentions you had to write a paper on a topic he recently explained. You decide to ask Alexander Vladimirovich about it personally and write to him.

"Hello, do I have to hand in my essay tomorrow?"

He texted you back a couple of minutes later

"Yes"

"Then don't wait for me."

"Let me ask you why this is?"

"I don't know what to write there! I'm not Mendeleev."

He wrote to you

"Miracle"

"What?"

"Remind me, what subject do I teach you?"

"Physics"

"What a clever girl)"

"And who is Mendeleev?"

"Physicist-scientist, no?"

You didn't understand what all these questions were about, and then he wrote to us

"Mendeleev is a chemist"
