It is often said that scientific instruments are an extension of our senses. Could it be otherwise? What sense organs does the ammeter continue – a device for measuring current strength or an experimental mouse with a grafted cancer tumor?

The sensitivity of devices is usually higher than the sensitivity of the senses, they do not get tired, their work does not depend on different conditions (light, heat, humidity, time of day, which are necessary for the functioning of the human sense organs, devices are not an extension of our senses, but rather copies of our senses, an ammeter can presumably simulate the amount of static electricity on the surface of the skin as a sensory organ.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
