Omnipresence Memes

The haunting of Leonhard Euler continues! Start learning literally ANY quantitative field and BAM—there he is, staring at you with those wide-eyed expressions like the cat in this meme. Differential equations? Euler's method. Complex analysis? Euler's formula. Engineering mechanics? Euler-Bernoulli beam theory. The man casually invented so many fundamental concepts that it's impossible to escape his mathematical gaze. You think you're learning something new but nope—just another playground where Euler left his fingerprints centuries ago. The mathematical equivalent of realizing your ex follows all your social media accounts.
