Presentation Transcript

  1. Science & Engineering

  2. What is Science? • Science is the systematic study of the natural world; the explanation and classification of knowledge of the physical world. • “The test of all knowledge is experiment”– Richard Feynman The Data So Far

  3. “The Difference” How could you choose avoiding a little pain over understanding a magic lightning machine? http://xkcd.com/242/

  4. How Is Science Done? • The Scientific Method! • Observation • Review Background Information • State the problem/Ask a Question • Form a Hypothesis • Design & Perform Experiment • Collect & Analyze Data • Draw Conclusions http://xkcd.com/683/

  5. Important Discoveries! • GalilleoGalilei – Heliocentricity, telescopes, falling bodies, motion, Experiments! • Marie Curie – Radioactivity, discovery Ra & Po • Albert Einstein – Relativity, photoassociation, • Isaac Newton – Gravity, Optics, Calculus… • Charles Darwin – Evolution/Natural Selection • Louis Pasteur - Germ Theory of Disease • ….

  6. What is Engineering? • Engineering is the practical application of science “design and build structures, machines, devices, systems, materials and processes that safely realize improvements to the lives of people.” • “Scientists try to understand nature. Engineers try to make things that do not exist in nature” – Y.C. Fung and P. Tong

  7. “Long Light” You can look at practically any part of anything manmade around you and think 'some engineer was frustrated while designing this.' It's a little human connection. http://xkcd.com/277/

  8. How Engineers Work

  9. Awesome Engineering • Pyramids of Giza • Hoover Dam • Panama Canal • Le Millau Viaduct

  10. Engineering – Not Just Structures • Flexible displays • Molecule-sized nanobots • Wrinkle-resistant fabrics • carbon nanotube-infused graphite tennis rackets • Self-cleaning glass • Bio-nanobattery • Bullet Proof goat milk spider silk…?

  11. Where Do They Meet? • Often, scientists act as engineers… and vice versa • Computers pioneered by Alan Turning, a mathematician • Theoretical basis for Laser came from Einstein, and developed by physicist Charles Hard Townes
