Saggi di naturali esperienze
Video   Text

 

The publication of the Saggi di naturali esperienze [Examples of natural experiments] in 1667 marked the end of the work of the Accademia del Cimento. The elegant and lavishly illustrated volume was introduced and edited by the Secretary, Lorenzo Magalotti. The Saggi contained a selection of the Academy's experiments "to determine the changes in the air due to heat and cold", on the "natural pressure of air", on vacuum, on "artificial freezing", on the incompressibility of fluids, on magnets, on the electrical properties of amber, on the propagation of sound and light, and on a host of other natural phenomena. The Saggi recounted only a tiny portion of the research conducted by the Cimento, by comparison with the hundreds of experiments recorded in the Academy's manuscript Diaries. For fear of provoking reactions from the Church authorities, the volume omitted the analysis of the true configuration of Saturn — a sensitive topic, given its major Copernican implications.
