Science Holiday Book Recommendations
Love history, science, and the history of science or know someone who does? Here are some book recommendations I would have loved to have gotten years ago
The History and Practice of Ancient Astronomy by James Evans
This book is a bible for anyone interested in astronomical reconstruction projects. A rich and almost indulgent book that covers how to engage in the practice of ancient astronomy like sundials and astrolabes and more.
He goes through the history and step-by-step details for reconstruction. It has been an invaluable tool for my research and a delight to read
I canāt recommend it enough, here is a link for a new copy but you can find cheaper used copies around as well
Sundials: Their Theory and Construction by Albert E. Waugh.
A small but wonderfully detailed book (link to a new copy, but I find the occasional copy in used bookstores pretty reliably)
Heavenly Mathematics: The Forgotten Art of Spherical Trigonometry by Glen Van Brummelen
āIn his words, he is the ābest trigonometry historian, and the worst trigonometry historianā (as he is the only one).ā A niche but beautiful topic in the history of Mathematics
This book describes a form of trigonometry that is related to circles. This topic is an older form of mathematics that isnāt studied as much since the 1970ās. I have been using it to solve problems for the astrolabe to mathematically transform 3D spheres into 2D circles
He splits up the details about the math from the history, so you can go into the depth you feel comfortable with

The Periodic Table by Primo Levi
The Royal Institution voted this to be the best science book ever written. If you like chemistry or even just science history in general, you canāt go wrong here (link to a copy). He is a masterful writer and had more books about his time in the Auschwitz concentration camp during WWII (If This Is a Man, published as Survival in Auschwitz in the US)
I haveā¦a lot more recommendations but this is a great place to start! Iāll post more, but if you are looking for some specific, send me an ask

First bit of serious forging after a year or so of wild medical rides. This is the first of two simple sundials that will be donated to a local rep theater fund raiser
Working on the math to understand the spherical projection for the Earthās sky based on different latitudes (0-90 degrees) to understand the ancient astronomical instrument--the astrolabe--and its internal plates that vary based on an observerās latitude
These projections are based on this brilliantĀ Astrolabe generatorĀ and give a good idea about how the zenith (the point in the sky directly above an observer) shifts and changes over different latitudes.
