First of all i want to tell u that science involves both natural science and and social science
we all know that we are making many changes in the technology and developing it in our day to day life enormously
and we don't have any idea that when it might not work or stop working.hence it is really important to know how these things were developed

here the development of the technology or science over the years is called history of science

hence we need to know how they were made and we can easily solve the problems related to them in future

nice answer...
thank u\
welcome from where did you get it..!???

It is important to know the history of science because only if we know the history of science we can predict the future of science ^_^
