Generally speaking , the history of science comprises a field of history whose main aim is to examine humanity's understanding of natural sciences and ability to manipulate it over the centuries. This offers the students involved in science with the remarkable advantage of becoming aware of the changes in technology and scientific paradigms over the evolution of the related fields over time.
I believe History of Science must be read to know the underlying myths, theories and fundamentals of science. It helps students to understand issues better
Sorry, maybe I am a little bit late with my answer. - Explaining for example the technical functioning of certain apparatus, particularly in chemical engineering and mineral processing, it should go along with the names of the inventors and the circumstances why it was built in exactly that way. In my lectures I like to show the photos of the inventors and that makes it for the students both vivid and tangible. When I have updated the chapter "flotation" in the Ullmann’s Encyclopedia of Industrial Chemistry, I also added a section about the historical development of cell types and for the first time, I could convince the publisher of the Ullmann’s, to show even portraits of the fathers of flotation.
Yes I like history of science. It is always important for the students because unless they read it they will never be able to understand and appreciate the technology evolution and its basis.
History of science is very important and especially for youngsters to realize how ingenious scientists from a century or more ago were when they came up with theories and verified them with long hand calculations. Sir Isaac Newton invented a new branch of mathematics called calculus in order to come up his equations of motion and his laws. Inventions these days are novel but it behooves us to read the history of science, the incremental progress made over decades and centuries and the methodologies those scientists used.
