Study of natural world involves designed, man-made world

14. MATH is important in engineering (read p. 118, third pgh) (do #8 & 10)
Advances in science can lead to new or improved technology through engineering
MATH is important in engineering (read p. 118, third pgh) (do #8 & 10)
In solving real-world problems, engineers think about… (pg. 119, all)
CONSTRAINTS – limitations
Ex. Only so much budget, laws of physics, etc.
TRADE-OFFS – giving up one advantage to keep another
Ex. Cost vs. strength of bridge

15. What skills make a good engineer?
