The theory of any subject takes a long time to retain in the memory; on the other hand, the practical subjects are retained in the memory for a longer time. When it comes to science then experimentation becomes an inevitable part of actualizing theories. Physics is a practical subject that is easily understood by experiments rather than theoretical knowledge.
