Solutions can also be implemented using computer software. Students should test any solution against the needs and criteria it was designed to meet. At this stage, new criteria not originally considered may be reviewed. Many scientific investigations require the contributions of individuals from different disciplines, including engineering. New disciplines of science, such as geophysics and biochemistry often emerge at the interface of two older disciplines.
Science often advances with the introduction of new technologies.
Solving technological problems often results in new scientific knowledge. New technologies often extend the current levels of scientific understanding and introduce new areas of research. Scientific knowledge is made public through presentations at professional meetings and publications in scientific journals. First and foremost, they must be consistent with experimental and observational evidence about nature, and must make accurate predictions, when appropriate, about systems being studied. They should also be logical, respect the rules of evidence, be open to criticism, report methods and procedures, and make knowledge public.
