Microscope enhances a scientist’s senses.

Explanation:

Our body has six senses. They are

eyes provide the sense of vision, ears provide the sense of hearing, mouth provides the sense of taste, nose provides the smelling sense skin provides the touching or feeling sense, brain provides the intellectual sense.

Among these senses, the tool which can enhance any one sense is microscope. Microscope is used to enlarge the microorganism or nano scale samples such that they can be visible clearly by human sight.

So it enhances the vision of eyesight of scientist helping them in understanding the shape of nano particles or cells of microorganisms etc., which are not visible in naked eye sight.
