Key Discoveries in Engineering and Design (Science Discovery Timelines)
by Christine Zuchora-Walske (Author)
Booktalk: What smaller scientific discoveries led up to major breakthroughs such as the assembly line, computers, or the Internet? Who first proposed ideas to solve problems? And how did the solutions change over time? Trace the history of key discoveries in engineering and design with timelines and find out the facts.
Many thousands of years ago, people tasked with raising stone structures faced a problem. How could they make openings, such as windows and doorways, in their structures without weakening them? How could they create roofs and ceilings that would support their own weight and any weight above them? Openings were important for light, ventilation, movement, and defense. Roofs and ceilings, of course, provided shelter for people and objects housed in the space below. But roofs or windows with open space beneath them ran the risk of caving in.
