Learn Turkish: Fizik dersini sever misin? - Do you like the physics lesson?

It uses the aorist tense to ask about a general fact or habit. sev is the verb root (to like), and -er is the aorist suffix. For aorist questions, we use the question particle mi and attach the personal suffix -sin (you) directly to it, giving us sever misin.

Why does dersini end with two -i suffixes?

The phrase for physics lesson is a noun compound: Fizik dersi, where the first -i links the word lesson to physics. Because this specific class is the direct object of the verb to like, it must take the accusative case. We add a buffer letter -n- followed by the accusative suffix -i, resulting in dersini.

Is there a difference between asking sever misin and seviyor musun?

In Turkish, the present continuous (seviyor musun) is heavily used to talk about general likes and dislikes, just like the aorist (sever misin). Both translate to 'Do you like?' and are practically interchangeable here, though the aorist slightly emphasizes that your feelings about physics are a timeless, general fact.
