Study calculus.
not because exams exist.
because reality moves.
• derivatives → how things change
• integrals → how change accumulates
• limits → what happens at the edge
• gradients → where systems want to go
• differential equations → how nature evolves
motion, heat, fluids, control, optimization, robotics, ML.
all of it speaks calculus.
without it, you see outputs.
with it, you see dynamics.
