D J Griffiths’s scientific contributions

... Using demonstration experiments, electric and magnetic field lines are visualized, for example, by semolina grains (Benimoff, 2006;Küchemann et al., 2021;Lincoln, 2017) or iron filings (Küchemann et al., 2021;Thompson, 1878), respectively. When representing a quantity as a vector field, the fields' properties, its divergence and curl, and further the integral theorems of Gauss and Stokes are of particular importance for physics applications (Griffiths, 2013). Accordingly, a sound understanding of vector calculus is of great importance for undergraduate and graduate physics studies. ...
