Nature of Matter
Electrical and electronic engineering essentially originate from exploiting the
motion of electrical charges. These constitute fundamental parts of matter, which
makes it essential to know its basic elements, namely the atoms. In the past, many
theories regarding the structure of an atom has been hypothesized; let’s consider
here the most relevant.
