Solid state physics Memes

Semiconductor physics strikes again. An electron hole isn't actually empty space—it's just the absence of an electron in a crystal lattice, creating what appears to be a positive charge. The confused cat perfectly represents every first-year physics student who expected something more... hole-like. Much like expecting actual bugs in computer code or real clouds in cloud computing. The disappointment is palpable.

That smug Pepe face when you've found the professor's cryptonite! Rhombohedral lattices are notoriously complex crystal structures with non-orthogonal axes and unequal spacing. Converting these to Cartesian coordinates requires a transformation matrix that would make even seasoned physicists sweat. It's like asking someone to manually compute SHA-256 encryption—technically possible but practically sadistic. The professor thought they were untouchable until you hit them with the crystallographic equivalent of "show your work." Now who's sweating through their tweed jacket?
