2. Chapter 1: Historical Antecedents in the Course of Science and Technology
A. Ancient Times
People were concerned with transportation and
navigation, communication and record-keeping, mass
production, security protection and also health,
aesthetics, and architecture.
Transportation – during ancient times, the vast world
was not fully discovered hence people venture out in
search for food and better environments.
 Communication – history, mapping, and
documentation of trade was important as well as
establishing a way of communication.
Weapons and armors – used as means of security and
protection and as offense to fight off invaders or
conquer lands.
