How to talk about nuclear
In your career as a professional in the nuclear community, chances are you will, at some point, be asked (or volunteer) to talk to at least one layperson about the technology you know and love. You might even be asked to present to a whole group of nonnuclear folks, perhaps as a pitch to some company tangential to your company’s business. So, without further ado, let me give you some pointers on the best way to approach this important and surprisingly complicated task.

The time-dependent transport equation in plane geometry has been solved numerically using the double spherical harmonics angular approximation and first-order finite differences. The monoenergetic case has been shown to meet both necessary and sufficient conditions for stability for reasonable values of the time step. The convergence and wave front propagation characteristics of the difference scheme have also been checked in special cases and found to be satisfactory. A computer program has been written to solve the difference equations of the multienergy, multiregion problem. Monoenergetic and multigroup calculations have been made which compare qualitatively with experimental results.
