Galileo's Pendulum: From the Rhythm of Time to the… por Roger G. Newton
The chapter on the actual physics of the pendulum's motion had a nice diagram but an incomprehensible explanation. I can work out a formula for the acceleration of the pendulum, and don't need help with that. It's the properties of the pendulum's motion, and how they arise from the forces on it that interest me, but the explanation in the book was far too muddled to convey much meaning, much less be convincing. The first chapter, on biological rhythms that are related to external stimuli was fairly interesting. The idea that apparent circannual rhythms may arise from the interaction of circadian and diurnal ones was the description of another emergent phenomenon.… (mais)
Annoiandosi durante la messa, un ragazzo di diciassette anni osserva un lampadario che oscilla sopra di lui. Da queste giovanili sperimentazioni Galileo elaborò la teoria dell'isocronismo del pendolo, dando origine agli studi di fisica dell'oscillatore armonico.
Saying that physics is six millennia old as a discipline seems a bit of a stretch, but this is a creditable and competent little history of it.
Good but not great.
This is a discussion of time-keeping, and when it covers the early material --- biological rhythms, the history of calendars and early clocks --- it does a great job. But when it gets to more modern times and discusses physics, it had nothing useful to say to me. Worth reading for the first half while ignoring the second half.
