Used to discuss objects or processes on an incredibly tiny scale, usually invisible to the naked eye. Under a microscope, you can see the nano structure of this material.
Pro Tip 2/3
Precision Required
When precision is crucial, especially in science or engineering, 'nano' is often used. Constructing microchips requires nano-level precision.
Pro Tip 3/3
Not for Time
While 'nano' means one billionth, it is not typically used for time except in 'nanoseconds'. The nano coating on these glasses makes them water-resistant.
