Micro Structure
&
Bonding Force
Micro Structure
Color
Usually dye
Seeing reflected light
ex) Flamingo
Structure
Reflect only blue color
ex) Butterfly of blue wing
Aerodynamic Characteristic
Zigzag-edged wing
Reduce the drag force
ex) Dragonfly
Adhesion
Many contact surface
Sum of many Van der Waals
ex) Gecko foot
Atomic Structure
Atomic particle
Proton
1.67 x 10^-27 kg
Anode
Main mass of atom
1 amu = 1/12 mass of C(12)
Isotope
Same atomic number
Different mass number
Many isotope in nature
ex) C, Ce, U
Neutron
1.67 x 10^-27 kg
Nonpolar
Electron
9.11 x 10^-31 kg
Cathode
Form matter
Subatomic particle

Allow same energy in system
ex) Gluon, Photon
Fermion
Have substance
ex) Semiconductor
Not allow same energy in system
Energy level
ex) Up, Down, Electron, Muon, Tau
Scalar
Higgs
Interaction with higgs field
Origin of mass
Antimatter
Opposite charge
Immediately offset with matter
History
Atom model

Bonding force
Attractive force
Inverse proportion to distance
Repulsive force
Inverse proportion to distance^n
Net energy graph
Shape
Usually not symmetric
Expansion by heat
Ideal symmetric
No expansion by heat
Well
Deep well means high melting point
