The current fad in advertising one's Department to potential engineering students is to claim to be at the forefront of nano-engineering, nano-technology or nano-materials. This talk will review some of the aspects of nano-materials in the teaching of Materials Science and/or Metallurgy. Since the symposium is in honor of my long time colleague and friend Professor Massalski, who will receive the 2006 Czochralski Prize, I will focus on nano-materials and phase equilibria. How we included nano in our 20th century curricula will be reviewed and how we now include it in the 21st century curricula will be presented and discussed. Some thoughts about nano and the future also will be presented. I will close with some thoughts on the danger of designing a curriculum around fads.
