The eternal battle between precision and practicality plays out in labs everywhere! Quality Control demands to know what sophisticated instrumentation you used, and there you stand, mighty in your safety goggles, proudly declaring you just... eyeball'd it. Nothing strikes fear into the heart of a meticulous scientist quite like learning that crucial measurements were determined by the highly advanced technique of "looking at it and guessing." Yet somehow those approximations work suspiciously often. The secret ingredient? Years of experience disguised as casual observation. Next time your supervisor asks for your methodology, just flex dramatically and say "my calibrated optical sensors" while pointing at your face.
