John made it back from San Francisco and Shannon is getting her new laptop setup. This week we took a break to talk about electron backscatter in scanning electron microscopes and think about what can modify the size of animals.

EBSD Measurements

• Electron backscatter diffraction
• Kikuchi Bands
• Bragg’s Law
• LPO Paper
• Optical Interference Figures
