The mathematical parallels between electrostatics and laminar fluid flow are exploited to develop a set of exercises that allow introductory physics students to discover Gauss's Law.
We report fndings of reciprocal transplant experiments intended to tease apart the roles of differentiation and plasticity in producing phenotypic variation across a geographic border between two plant subspecies. Clarkia xantiana ssp. xantiana and C. xantiana ssp. parvifora are California-endemic annuals that replace each other along a westG??east gradient of declining precipitation.
