Guess how tall Shaquille O'Neal is in nanometers?

The nanometer is a unit of measure – just like inches, feet, and miles. A nanometer is a one-billionth of a meter, and used to measure
things that are very, very small. Shaquille O'Neal, a very tall basketball player, is 2,160,000,000 nanometers tall!Nov 5, 2013

2.16 billion .. haha .. i forgot what size a nanometer was, so recently read

What are Nanoparticles?

By Dr Ananya Mandal, MD

A nanoparticle is a small object that behaves as a whole unit in terms of its transport and properties.

Size of nanoparticles

In terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles are sized between 1 and 100 nanometers. Nanoparticles may or may not exhibit size-related properties that are seen in fine particles. Despite being the size of the ultrafine particles individual molecules are usually not referred to as nanoparticles.

Nanoclusters have at least one dimension between 1 and 10 nanometers and a narrow size distribution. Nano powders on the other hand are agglomerates of ultrafine particles, nanoparticles, or nanoclusters. Nano particle sized crystals are called nanocrystals.

Nanoparticle research and uses

Nanoparticle research is currently the most studied branch of science with the number of uses of nanoparticles in various fields. The particles have wide variety of potential applications in biomedical, optical and electronic fields.

History of nanoparticle research

The history of nanoparticle research is long and the use of these particles dates back to the 9th century in Mesopotamia when artisans used these to generate a glittering effect on the surface of pots.
.. more on little things which lead to big advancements in many ares .. http://www.news-medical.net/life-sciences/What-are-Nanoparticles.aspx

.. chuckle .. betcha not many, even if they have any idea what a nanoparticle is, would get
if asked, 'How old do you think nanoparticle research is? very close to the 9th century .. lol

F6, that '1 kilobyte of memory where each bit is represented by a single atom' is quite something .. wow .. the mind boggles even more!
