An extensive collection of studies and material on Castel del Monte.
A key study is the geometric design of the castle plant. The study defines a new model for this geometric design process, a subject that many scholars have grappled with.
The study identifies the design rationale by medieval architects, one that reproduces the design forms in all minute details. Much like an algorithm, this design process is used to predicate the actual measurements with uncanny accuracy, evidence that this must be the process followed by the medieval architects.
The study starts from the religious precepts that guided the designers in the Middle Ages, and retraces the thinking process by the architects of Castel del Monte as they proceeded step-by-step with the geometric design, defining along the way the forms and calculating their dimensions.
Many scholars have tackled this difficult quest, to decipher the geometric design of Castel del Monte. It is a natural response as the visitor to Castel del Monte is struck by the recurring geometric forms and the perfection of the edifice. Heinz Götze called Castel del Monte the geometric marvel of the Middle Ages.
This new study provides the answers. It shows that the plant design was more than an origami-like procedure; it was a rational engineering endeavor within the context of the culture and scientific knowledge of the Middle Ages.
The proof is in the results: the geometric forms of the plant design are replicated in all details; the form dimensions are predicated to a precision of less than 0.5%.
Castel del Monte is a window in the science at the height of the Middle Ages, the period of Gothic architecture.
Stray voltage deals with small voltages found on the grounding wires of electric power systems and all interconnected appurtenances, such as metallic water pipes. They are very low and innocuous to humans, except in rare circumstances.
The study of stray voltages was directed at dairy cows, which are more sensitive than humans because of their living environment on the farm. The research reached its highest interest in the 1990s, at the same time that the related concern for potential health problems from ground currents on power line grounded conducors became a subject of intense studies, an issue more broadly known as EMF (Electro-Magnetic Fields).
Much of the EMF health research has abated since; some research has continued, such as cell phone EMF.
The stray voltage presentation was prepared around 2001 to unravel the misconception about dairy cow stray voltages, providing a layman explanation.
