This quote from a fantasy book describes being a chaplain so well.

Folk who've been following me for a long time will remember that last autumn I was posting pictures of doing the joinery for a new workshop. And then I went mad, and got ill, and for most of this year there's been no progress.
But my friend Lucy has been here for a week, and between the two of us the frame is now erected. Now I need to sort the timber stack (which hasn't been improving while I've been ill), erect a roof, and build some walls. But the bit I couldn't …

Abstract: The cosmic web is one of the most complex systems in nature, consisting of galaxies and clusters of galaxies connected by filaments and walls, and separated by large empty regions known as cosmic voids. The most common method for describing the web is the correlation function and its derivative, the structure function and fractal dimension function. In this paper I review the fractal properties of the cosmic web within the concordance {\Lambda}CDM framework. I describe how the fractal function is derived from the angular and spatial distributions of galaxies and discuss the relations between these approaches.

Abstract: Adhesion between NaI(Tl) single crystals and the walls of quartz ampoules remains a major limitation for Bridgman growth under sealed conditions, particularly for applications requiring ultra-radiopure scintillators for dark matter searches, where sealed handling is essential. In this study, ammonium iodide (NH4I) was used as an additive to generate HI in situ, thereby suppressing the NaOH-SiO2 reaction that forms adhesive sodium silicate phases. Small-diameter crystals (8 mm) were first grown to determine the NH4I concentration required to eliminate adhesion. The optimized condition was then applied to the growth of a large NaI(Tl) crystal. A crack-free and bubble-free NaI(Tl) crystal with dimensions of 3 inches in diameter by 3 inches in length was successfully grown. The crystal exhibited a light output of 59,000 photons/MeV, which is higher than that of the commercial NaI(Tl) crystals used as references in this study.
