spec: We are reciprocally productive when others ’ theories motivate new observations and questions in our own realms and , conversely , when others ’ observations become incentives for us to develop new theories . Additional research is required to determine precisely the ideal intensity . You need to trust the public officials that they are doing the job , without publicizing to the whole world where our exact , specific deficiencies are . The drawbacks and penalties attendant upon our profession are taken into full account , as we well know , by literary men , and their friends . The invention of better , more precise instruments allowed us to develop new theories about our Earth and its inhabitants . This raises the potential for multi-level governance . With wireless technologies improving , more and more remote sampling and monitoring applications are increasing . We are developing new theories to predict the properties of such systems , including the subtle competition between gelation , crystallization and phase separation , structural reorganization in sticky particle suspensions , and the role of polymer rigidity , polymer-particle adhesive interactions and other chemically specific effects .
