Sinopsis
Excerpt from The Popular Science Monthly, Vol. 3: May to October, 1873
If thin plates of glass or metal be clamped in the centre, and fine sand scattered over the surface, they may be set into vibration, and the sand will be tossed away from certain parts of the surface and col lected in other parts, forming regular geometrical figures. The sand collects at the lines of rest, which are called nodal lines. Fig. 3 rep resents this experiment, the vibration being produced by a fiddle-bow, while the application of the fingers at different points determines the lines of rest and the geometrical figures. Fig. 4 represents a number of the beautiful patterns that were obtained by Chladni, who first drew attention to this interesting phenomenon.

Excerpt from The Popular Science Monthly, Vol. 3: May to October, 1873
That niris the medium of sound is proved by the fact that, when vibrations occur in space void of air, the silence is not broken. If a bell suspended by a string in a vacuum be struck, nothing is heard, al though, if it is in contact with the jar, the vibra tions are communicated to the outer air, and sounds produced. That air transmits the kind of motion that it receives is also proved by the fact that it will take up vibrations at one point and communicate them to a distant object that is capable of vibrat ing in the same way.

Paperback. Condición: New. Print on Demand. This book investigates the hypothesis of natural selection to illuminate the factors influencing the evolution of human society. The author examines how the process of natural selection may have shaped the development of human groups into organized, cooperative societies. The author argues that many seemingly disadvantageous behaviors or beliefs may have been advantageous in the early stages of human development. For example, the author posits that war, while appearing destructive, may have been a necessary catalyst for the development of civilization. The author also suggests that the suppression of individual freedom may have been beneficial in the past by promoting group cohesion. The book ultimately explores the profound implications of the theory of natural selection for understanding the development of human societies and the factors that have shaped their progress. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Nº de ref. del artículo: 9781333808839_0
