Slide Rules and Mathematics | Astrolabe | Design and Parts @sliderulesandmathematics9232 | Uploaded January 2022 | Updated October 2024, 2 hours ago.
Initially designed around 200 BC, the Astrolabe is an analog computer based on a Geocentric Solar System. The iPhone of its day, the design reached its pinnacle around 800AD in the Islamic World. It was well known amongst the educated classes and mariners in the Middle Ages.
In this episode we will discuss the construction and parts of the Astrolabe, using both a precision brass model and a wooden one I built from a kit. We will discuss the Zodiacal Calendar, Modern Calendar, the Equinox and Solstice and how to sight a celestial body, tell the time of day, and calculate the time of dawn. First of a multipart series on Slide Rules and Mathematics.
This was taken from a live stream presentation on 'Common Sense Science' and edited with new material. Note, the focus in this is off a bit- it is automatic and not adjustable (nor can it be fixed so it changes when I put my hands in the field of view). But I did include clear photos so listen to the description I give and there will be a clear photo to review shortly.
