Physical meaning of concepts "electrical charge" and "electric field"
In physics, as in other sciences, scientific results are often presented formally, without appropriate disclosure of their physical meaning. For example, in the discussion about interacting charged bodies the meaning of charge is not discussed. It is shown that the term "electric charge" in science is conditional and has an auxiliary symbolic meaning. In reality there is a "positive" and "negative" substance in nature. There is no any charge isolated apart from the substance. In fact, in nature there are a proton and an electron as a matter.
