On a molecular level, the entropy of mixing is of interest because it is a macroscopic variable that provides information about constitutive molecular properties.
The experiments require macroscopic quantum state preparation and quantum erasure by a hypothetical quantum computer which is currently outside experimental possibility.
Random number generators can also be built from random macroscopic processes, using devices such as coin flipping, dice, roulette wheels and lottery machines.
The term mechatronics is typically used to refer to macroscopic systems, but futurists have predicted the emergence of very small electromechanical devices.
Since the binasuan inverts the arm through rotation, it is sometimes given as a macroscopic, physical demonstration of the rotation properties of a spin- spinor.
