Technology and materials engineering

Advances in material science are an important factor in the development of new technology and innovation we see around us every day.  From light weight materials to drive fuel efficiency in cars and aircraft to innovation in the development of micro-electronics.  Often the inventors of new devices or macroscale systems get the limelight from these contributions to science, engineering and its effect on society.  However, there are many scientists that are working hard behind the scenes driving innovation in the form of materials science.  The advancement in materials science directly correlates to the development of new instruments and devices.  These developments help propel us in the areas of photonics & optomechanics, consumer electronics, fuel cells and energy system and a plethora of other areas of technology.

The following open access article discusses this topic with several links to many of these developments throughout history.

Earth-Moon Waystations

Earth-Moon Waystations

Why establish “waystations” at the Earth-Moon L1 point or other locations in space, as some have proposed? John Strickland draws an analogy to terrestrial transportation systems to explain how such facilities could make space exploration and development more affordable.
