  • 1. An Introduction to the World at the Nanometer Scale
  • 2. What is NANO?
  • 3. What is the smallest thing you can think of?
  • 4. How big ( small ) is a nanometer? Nano means “dwarf” and denotes a billion th 1, 000, 000, 000 . = 1 billion 0 . 000000001 = 1 billionth or… 1 x 10 -9 = 1 billionth Nano meter , nano second , nano liter
