All medical doctors and engineers are scientists

yes and no

yes because there are certain units that research better technology and formulas

no because the majority do not research. they treat public needs with what they already have

Not all doctors and engineers are scientists, as many of them only dedicate themselves to applying existing science but not to carrying out such research. In order for a doctor or an engineer to be considered a scientist, they must apply the scientific method and systematically do research to improve the understanding of nature.
