Macroscopic is commonly used to describe physical objects that are measurable and observable by the naked eye. When applied to phenomena and abstract objects, it describes existence in the world as we perceive it. Lengths scales generally considered macroscopic roughly fall in the range 1 mm - 1 km.
The term macroscopic may also refer to a "larger view", namely a view only available from a large perspective. A macroscopic position could be considered the "big picture".
- A macroscopic view of a ball is just that: a ball. A microscopic view could reveal a thick round skin seemingly composed entirely of puckered cracks and fissures (as viewed through a microscope) or, further down in scale, a collection of molecules in the rough shape of a sphere.
Macroscopy in physics
In physics, macroscopy is can be a physical trait applied relative to what one is observing. If one looks at a galaxy, a star is a microscopic entity, even if it is many, many orders of magnitude larger than us.
