A Brief History of the Measurement of Time Part 1

This article explores the history of time measurement, beginning with ancient civilizations like the Sumerians and their development of calendars. It discusses the challenges in harmonizing civil timekeeping with astronomy, including sidereal and solar years, and the division of days into hours. The article also covers the Roman and early Christian calendars, highlighting their inaccuracies and the historical attempts to reform them, such as the Julian and Gregorian calendars and the fixing of Easter.

The Horniman Museum Reflective Ceiling Dial

This article details the design and delineation of a reflective ceiling dial at the Horniman Museum, inspired by a sundial trail lecture. It sets out the mathematical formulation for determining coordinates on the dial, explaining how it relates to an equivalent declining, reclining dial. The authors emphasize that reflective dials are not inherently more complex to delineate than other planar sundials, providing formulas for angle and length calculations, and tables of coordinates for various times and declinations.

Newbury 2000 - A Grand Day Out

This report details the Newbury 2000 event, a British Sundial Society gathering showcasing various sundial exhibits. Highlights include John Moir's rainbow and bifilar dials, a cycloidal dial, and Piers Nicholson's prototype horizontal dial with accurate alignment features. Tony Wood presented "3 Cheap and Dials" and updated on the mass dial register. Peter Ransom displayed sundial-themed items, and David Young showed eclipse phenomena. The event concluded with an award for the Make a Sundial competition.

The Glossary and the Gnomonic Novice

A. F. Baigent's piece reflects on the "BSS SUNDIAL GLOSSARY," having 'tested' the glossary on six guinea pig subjects for their understanding of 20 words from the glossary. He suggests improvements such as additional tables for equation of time and sun declination, plus more diagrams. The author acknowledges John Davis's hard work on the glossary.

Millennium Sundials for Nottinghamshire Schools

Describes a Nottinghamshire County Council competition for schools to mark the Millennium, with sundials as prizes. The author was consulted on the design, choosing an updated ancient hemicyclium: a hemispherical bowl on a plinth, with a rod gnomon. The ceramic dials, crafted by Danel Sherlock, feature hour, equinox, and solstice lines. A booklet guides setup and reading, hoping the dials will serve as useful learning tools for the winning schools.
