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.
Love this question! One of the many ways that engineers can turn science into reality is through the processes of trial-and-error and testing. These processes mimic other sciences in that an engineer may, for example, write a piece of code, edit as needed in order for the code to run and then assess whether the results of that code run give the expected results. If it does, great...then the engineer can move on to determining if that result meets the need of the task at hand. In other words, the activity can be successful but if doesn't provide an acceptable fix to problem, then it won't meet the "reality" of what is needed. If it doesn't run, then this is were tenacity and determination in trial and error comes in...and sometimes some healthy partnerships can help as well :).
A completed task can be interpreted as one that is reproducible, sustainable and meets the need of the problem at hand. Having the ability to do this type of work, for various problem streams, is a way that engineers turn science into reality.
Hope you find this answer helpful. Best of luck to you!
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.
