Nanometer: The Tiniest Thing


CAROLYN’S DAILY POSTS: 2011

NANOMETER: THE TINIEST THING

  Nanometer: one billionth of a meter

(The prefix “nano” means “one billionth”)

     Consider this: a sheet of paper is about 100,000 nanometers thick. A typical human hair is about 50,000-100,000 nanometers wide. A typical germ is about 1,000 nanometers.  The human eye can see in the range of 400-700 nanometers.

     Inside the computer I am typing this post on are tiny switches that measure only 100 nanometers wide. About 1,000 of these switches can fit across the width of a single hair. Modern computers have about 100,000,000 switches packed inside, stacked one on top of another. We use nanotechnology to make these tiny switches.

     Nanotechnology is the understanding and control of matter at dimensions between approximately 1 and 100 nanometers,   and is generally applied to the imaging, measurement and manipulation of things at dimensions between 1 and 100 nanometers.

     The field traces its start to a classic 1959 lecture by Nobel Prize-winning physicist Richard P. Geyman: There’s Plenty of Room at the Bottom in which he said The principles of physics…do not speak against the possibility of maneuvering things atom by atom.

           One inch includes  25,400,000.nanometers. Using this, calculate how tall you are in nanometers. Shaquille O’Neal is a very tall 2,160,000,000 nanometers.

     It is commonly understood that each of us considers our being to be the center of the universe. And compared to a nanometer, we are massive beings. However, in terms of the universe and beyond, we measure much smaller than a nanometer. We are insignificant beings, a mere blip on the screens of time and space.

     ‘Tis the conflict of each human being to come to terms with being a center being and being insignificant blip. While contemplating this contrast, our task is to be in relationship with each other, to make a positive difference in the each life we meet on our journey here on earth.
