Physics nerds fighting over notation is the ultimate academic Spider-Man pointing meme! The Planck-Einstein relation (E=hf, E=hν, or E=hω) describes the energy of a photon, but physicists can't agree which symbol to use for frequency.
It's literally the same equation three ways - energy equals Planck's constant times frequency - but everyone's ready to throw hands over their preferred letter. This is why physicists can't have nice things. They'll spend hours debating notation while the universe just keeps doing its thing regardless.
Next up: mathematicians brawling over whether to use i or j for imaginary numbers. The struggle is real... unlike their numbers.
