As we mentioned last week, our navigator was out of the office teaching a professor how to use his sextant. Having decades of experience in both the observations and the calculations involved, he certainly has a firm grasp of the subject. But that’s not always the quality you need in a teacher.
Our astronomer and our navigator are away from headquarters at the moment, showing a Professor of Physics how to use his sextant. This style of instrument was the mainstay of nineteenth-century astronomy: made of brass and glass, with precise scales engraved on them for careful measurements. The people who used them had to work in a different way from current astronomers and must have had a different approach to life.
In the Five Colors Science & Technology library of photography are a number of old books that we still find interesting. Apart from details of procedures and chemistry that are hard to find elsewhere, they show the different ideas, through the years, of just what was a good photograph.
Our navigator had the pleasure of attending a fencing match this past weekend as a spectator. The range in ages of the participants was unusually large, which highlights some important considerations about newer and older people and things.
