Science & Engineering
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
“The Difference”

How could you choose avoiding a little pain over understanding a magic lightning machine?
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
Important Discoveries!
• Galilleo Galilei – 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• ….
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
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.

How Engineers Work
Awesome Engineering
• Pyramids of Giza• Hoover Dam• Panama Canal• Le Millau Viaduct
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…?
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
