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.

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
