  1. Molecular Nanotechnology in Aerospace: 1999 • Dream: • 1018 MIPS computers [Drexler 1992a] • 1015 bytes/cm2 write once memory [Bauschlicher 1997] • Three ton 4 person SSTO [Drexler 1992b] Al Globus Veridian-MRJ Technology Solutions, Inc. at NASA Ames Research Center http://www.nas.nasa.gov/Pubs/TechReports/NASreports/NAS-00-001/

  2. Three Pillars of Molecular Nanotechnology • Atomically precise control of matter • Molecular machines • Programmable matter Our favorite molecules: carbon Nanotubes http://www.nas.nasa.gov/Pubs/TechReports/NASreports/NAS-00-001/

  3. Atomically Precise Control of Matter http://www.almaden.ibm.com:80~/vis/stm/atomo.html [Dekker 1999] http://www.nas.nasa.gov/Pubs/TechReports/NASreports/NAS-00-001/
