What do you think would be the implications of this to the society the engineer went to would be? In the short term and long?

Being a Mechanical and Aerospace engineer (student), I would say that the advancement of the infrastructure of the cities would be the first thing that one would work upon. If I could get the nations/societies to follow these, diseases could be wiped out before they ever become a threat to the populace, and if I choose to go to Europe during the dark age, I could prevent the black plague from killing 2/3rds the populace. While doing that I would work on various steels, (iron + carbon alloys) to increase not only the weapons and infrastructure but the over all technology of the nations/societies I was in.

Also, what do you think we would have today because of the possible early scientific advancement?

I leave out chemical, electrical, and the other sciences from this question as they need a lot of prepared materials in order to do their jobs. These materials would be extremely hard to find with out significant help, relative to the iron (and its various steel alloys), wood, and stone materials that any Mechanical/Aerospace/Civil Engineer is familiar with.
