5. Introductions
• 1) A little bit about yourself – major, interests
• 2) Why this course – is it a prereq, what do you hope to gain
• 3) Fun fact that you want to share
6. What makes up a material?
Properties of diamond such as it’s brightness and hardness are determined from the nuclear and atomic scale
Nucleus (10-15 m) Atom (Carbon) (10-11 m) Atomic lattice (10-10 m) Many lattices=Diamond
8. Class Goals
• Learn science (physics, chemistry, biology) in context of everyday
materials
• Active problem solving: How to reduce a seemingly complex problem
into most basic components
• Integrating concepts learnt to a physical worldview
10. Length scales and ratios

Activity: Given that the ratio of the
length of a football field to the diameter
of the
Earth is roughly the same as the diameter
of the nucleus as compared to the atom,
What is the diameter of the nucleus?

Editor's Notes
Over the last decade of research at Emory, GT
I realized there is a lot of interesting science to be learnt from everyday experiences, and this cuts across my research interests
