Historical Science:  Non-repeatable, non-observational, non-testable   (e.g., the origin of the universe — Yes, the origin of the universe is historical science because no human was alive to observe it happening, nor could anyone repeat what happened even *if* they did observe it!)

Observational Science:  Is repeatable, is observable, is testable   (e.g., the study of medicine or the study of mechanics — You can actually observe things happening (e.g. mechanics), test and verify your findings.)
