- I understand why the fourth chapter is called "Accidents Waiting To Happen"; due to the previous accidents of bridges collapsing there is bound to be more.
- Now I know how many people were injured and killed because of the collapse of the Kansas City Hyatt Rengency Hotel skywalks; 114 were killed and 200 were injured.
- After the skywalks accident; many engineers reviewed and discussed the problem that caused the collapse; that's a good thing to learn from your mistakes.
- I understand why the fifth chapter is called "Safety In Numbers"; engineers do lots of calculating in order to be precise.
- I don't understand why the factor of safety is often referred to as the factor of ignorance.
- Who is David Billington?
- Who is Robert Stephenson?
- What did they deem to be the problem that caused the Kansas City Hyatt Rengency Hotel skywalks to collapse?
- What types of math do engineer use to construct/build structures?
- Prescience: knowledge of things before they exist or happen; foreknowledge; foresight
- Precipitately: to hasten the occurrence of; bring about prematurely, hastily, or suddenly
- Quantifiable: to determine, indicate, or express the quantity of
- Indirect Characterization: "Although the design engineer does learn from experience, each truly new designer necessarily involves an element of uncertainty." (page 100). New designers don't learn from experience because they have very little of it.
- Metaphor: "... but the structural success of another traditional design is no more news than a man who does not rob a bank or does not bite a dog." (page 106)
- Describes the safety of using math properly for engineering and an engineer who learns from your his/her mistakes is a good one.
