Science is reality! I believe you mean concepts to reality ... We do that though science :P
Science give us the governing relationships in materials, structures, fluids ... and upon them we build systems to satisfy a certain goal.
Engineers take ideas or concepts and make them realities. They use science, reasoning, and ingenuity to either create or improve something. Ideas are great, but they benefit no one until they are developed into a practical solution that people can use. Understanding the problem, soliciting solutions from as many people as practice, using scientific principles and developing a solution is what engineering is all about. Good luck.
