"General anesthesia — the enabler of modern surgery and medical intervention — is one of the great triumphs of the scientific method. Ether, the compound from which almost all modern anesthetics are derived, was discovered largely by luck and its derivatives through trial and error. As a result, however, much about these drugs remains mysterious. Even today, doctors are baffled as to why exactly anesthetics cause unconsciousness in patients. (See the most common hospital mishaps.)"
