Main Difference
The main difference between Last and Past is that the Last is a mechanical form that has a shape similar to that of a human foot and Past is a subdivision of time.
Last
A last is a mechanical form that has a shape similar to that of a human foot. It is used by shoemakers and cordwainers in the manufacture and repair of shoes. Lasts typically come in pairs and have been made from various materials, including hardwoods, cast iron, and high-density plastics.
Past
The past is a term used to indicate the totality of events that occurred before a given point in time. The past is contrasted with and defined by the present and the future. The concept of the past is derived from the linear fashion in which human observers experience time, and is accessed through memory and recollection. In addition, human beings have recorded the past since the advent of written language.
The past is the object of study within such fields as history, memory, flashback, recollection, archaeology, archaeoastronomy, chronology, geology, historical geology, historical linguistics, law, ontology, paleontology, paleobotany, paleoethnobotany, palaeogeography, paleoclimatology, terminology and cosmology.
