comment Does Earth really have two high-tide bulges on opposite sides?
Welcome to Physics SE! You provided interesting information, but did not answer the question "Does Earth really have two high-tide bulges on opposite sides?" You guessed it has something to do with tectonitc plate movements, but did not give a reference to underline it. Anyway welcome :)

comment reflection at intersection of 2 mirrors
+1 But the specifically asked within geometric optics. I agree however, that the application of a deeper concept than geometric optics may be applied. Depends on application.

comment How to specify BRDF measurement
+1 Nice question. To measure all materials from perfect mirror to absoulte black diffusor (2% of incident light is cosine distributed in hemisphere) your detector needs a large dynamic range. Can you select a range of materials between these two criteria? To rephrase it: Do you want to measure blackout materials to stray light reduction or optical media?

comment Moment of inertia of disc with a hole
+1 correct for rotational symmetric case. In general the hole isn't at the center of the disk. In that nonsymmetric case Parallel axis theorem has to be applied to compute moment of inertia of the hole.
