>>11624910real analysis is a precise mathematical theory where all terms (such as limit, continuous function, differentation etc.) are rigorously defined and all claims are proved from the definitions using logic.
calculus is a small part of real analysis consisting of computations and applications to engineering and physics.
epsilon and delta are greek letters commonly used in real analysis proofs.
calling the non-computational part of analysis epsilon delta autism is supposed to ridicule it as superfluous. since a theory works only as a whole, or doesn't work at all, it indicates that the poster is either being ironic, or braindamaged.
