1.36(a). When the material changes dimensions as a result of an imposed mechanical force, a permanently polarized material such as quartz (SiO2) or barium titan-ate (BaTiO3) will produce an electric field. This behavior of piezoelectric materials when subject to an imposed force is depicted ...
(often 3years for grants from NASA or NSF to US-based researchers) and the preclusion of rapid reprioritization in the face of discoveries can lead to frustration. For instance, the Huygens landing on Titan and the paradigm shifts that accompanied it occurred at an awkward time in the ...
