The eternal struggle between notation systems! The physicist writes √=Ir (square root equals current times resistance), while the chemist writes √=23 and Ir=77 (iridium's atomic number). When combined, we get 23=77, which makes the mathematician have an existential crisis. This is what happens when different scientific languages collide - mathematical impossibilities that would make Euler roll in his grave! Interdisciplinary communication: 0, Scientific confusion: 100.
