The nanoHUB was developed by the Network for Computational Nanotechnology and is funded by the National Science Foundation. For a thorough introduction to "What is a Nano?", visitors should go to the "About" section. Here they will find an excellent definition of nanotechnology that not only explains how big a nano is (one billionth of a meter, for those who didn't know already), but it also explains what different types of scientists/professions see nanotechnology accomplishing. For instance, electrical engineers view nanotechnology as the "science of making things small", chemists as the "science of making things big" and material scientists as the "science of finite size". Back on the homepage, visitors will find the four main tools nanoHUB offers to visitors: "Simulate", "Research and Collaborate", "Teach and Learn" and "Share and Publish". Some of the "Resources" include "Buckyballs", which is an animation of a 3-D Molecular Model developed for the Children's Museum Nanotechnology Exhibit. They will also find an animation on "How Semiconductors and Transistors Work". Visitors should also check out the "Hub How To Series", which is located in the lower right hand corner of the homepage for videos on how to use nanoHUB.
