Dur earlier quantity 14 used to be dedicated to an exposition of the themes of sensitivity research and uncertainty thought with its improvement and alertness in nuclear reactor physics on the middle of the dialogue. during this quantity, we go back to our accepted structure as a range of themes of present curiosity, authored through these operating within the box. those subject matters diversity from the theoretical underpinnings of the (linear) Boltzmann delivery equation to a resume of our ex pectations in what nonetheless could be considered twenty-first century expertise, the world's fusion reactor application. within the first article of this quantity, we have now Protopop escu's research of the constitution of the Boltzmann equation and its suggestions for strength and space-dependent difficulties of an eigenvalue nature. There lengthy has been a curious "folk historical past" influence during this sector~ Wigner and Weinberg may possibly de scribe it as "what was once usually identified was once more often than not untrue". This account of the Boltzmann equation without doubt will express rigorous foundation for our expectancies of convinced suggestions may be well-founded on research. Ely Gelbard's evaluate of the equipment of picking out diffusion-type parameters in advanced geometries the place basic diffusion concept will be welcome has required simply as a lot rigor to figure out how such modeling may be made actual, even if to a extra instant and functional objective. the 2 articles may be visible as fascinating contrasts, elements of a similar underlying challenge exhibiting it appears diversified points of a similar relevant core.
