  1. Abstraction • Lesson 1 presented by Dr.Natalie Kuldell

  2. Reverse Engineering GermanWehrmachtskanister, 1930s Fuel Cans used by WW I British army • Leaked • Need wrench and funnel to use • “Flimsies” • Snapcap • X-marks for strength, expansion • Plastic lined • Pressed seems • “WWII JerryCans”

  3. Reverse (historical) Engineering "Study the past, if you would divine the future"-Confucius "Learn from your mistakes"-my mom

  4. Forward Engineering 238 teams of engineers 8 mainframe computers 2200 workstations Scientific understanding of materials, physics, atmosphere ~100 year history of manned flight Commercial needs (#passengers, cost, distance) Consumer data

  5. Forward Engineering Scientific understanding of materials, physics, atmosphere

  6. Forward Engineering: 154, 154, 154… Wing stress test video

  7. Abstraction Hierarchy a human invention designed to assist people in engineering complex systems Some system designers Other experts who integrate of subcomponents Some experts in electrical system wiring

  8. Abstraction Hierarchy a human invention designed to assist people in engineering complex systems • Everyone has to do their job right for the final product to work • No single person understands everything about the final product • Interfaces between layers are critically important

  9. Abstraction Hierarchy a human invention designed to assist people in engineering complex systems Assemblies of devices make a system Assemblies of parts make up devices Sequences of DNA encode “parts”

  10. Why is abstraction useful?

  11. Abstraction • Lesson 1 presented by Dr.Natalie Kuldell
