"For the telescope build in question, [Unnecessary Automation] needed a concave mirror. Trying to get that sort of shape with glass can be difficult. However, there’s such a thing as a “liquid mirror” where spinning fluid forms into a parabolic-like shape. Thus came the idea to spin liquid resin during curing to try and create a mirror with the right shape."

"In the previous installment we concluded our journey through the Ancient Ages by introducing the first women who contributed to science, technology, engineering and mathematics. This time we move on to the Middle Ages where medicine was the one that benefited the most from the contributions made by women, both geographically and temporally distanced."

"Keng Hsien-Seng (around 975 A.D.)

A Chinese woman, daughter of an eminent scholar named Keng Chhien, she is described by Wu Shu in his writings on science as a woman who from a young age was intelligent and liked to read books. She was also fond of writing, wrote poetry worthy of compliments, but who was also familiar with Taoist techniques and who could control spirits. She became an expert in yellow and white alchemy with many other powerful, mysterious and incomprehensible transformations. Wu Shu says that no one knew how she obtained all this knowledge."

"Elements is an eclectic, evocative, and resoundingly beautiful treasury of imagery exploring depictions of the elemental forces that reveal their profound significance to ancient philosophers, alchemists, and astrologers, and modern artists, photographers, and scientists alike. Expertly curated, themed, and paired by image alchemist Stephen Ellcock, modern and visionary images are juxtaposed with the ancient and arcane, and the creative power of the elements is contrasted with the disastrous. Following physician and occultist Robert Fludd's (1574-1637) order of the elements, Ellcock guides readers through a remarkable selection of images, ascending from earth through water, air, and fire before culminating in the most spiritual of the elements, celestial aether."

"Alchemy has often been placed in the realm of mysticism, bizarre symbolic illustrations, and secretive societies, but its origins reveal a more intricate and multifaceted saga. It emerged at the crossroads of science, mysticism, and philosophy, evolving over centuries in various cultural contexts. From the Egyptian art of transformation, the Greek philosophical traditions, to the meticulous Chinese Taoist practices, alchemy has woven itself into both the practical and metaphorical tapestries of human understanding. Central to its evolution are two overarching paths: the outer physical pursuit often associated with laboratory alchemy, and the internal, transformative journey known as inner or spiritual alchemy. These two trajectories, though distinct, often mirror one another in purpose and symbolism."
