Cats’ Paws and Catapults by Steven Vogel
Cats’ Paws and Catapults: Mechanical Worlds of Nature and People - Kathryn K. Davis,Steven Vogel

TITLE: Cats’ Paws and Catapults: Mechanical Worlds of Nature and People

 

AUTHOR: Steven Vogel

 

DATE PUBLISHED: 2000

 

FORMAT: Paperback

 

ISBN-13:  9780393319903

__________________________

DESCRIPTION:

"Nature and humans build their devices with the same earthly materials and use them in the same air and water, pulled by the same gravity. Why, then, do their designs diverge so sharply? Humans, for instance, love right angles, while nature's angles are rarely right and usually rounded. Our technology goes around on wheels—and on rotating pulleys, gears, shafts, and cams—yet in nature only the tiny propellers of bacteria spin as true wheels. Our hinges turn because hard parts slide around each other, whereas nature's hinges (a rabbit's ear, for example) more often swing by bending flexible materials. In this marvelously surprising, witty book, Steven Vogel compares these two mechanical worlds, introduces the reader to his field of biomechanics, and explains how the nexus of physical law, size, and convenience of construction determine the designs of both people and nature. "

__________________________

REVIEW:

 

This is an interesting and informative, scholarly, comparative overview of the difference between the way nature and humans engineer and manufacture things, the differences in the substances each uses to make those things, and the possibilities of why man and nature make things differently. Vogel has a clear, easy to understand writing style and provides many examples and diagrams to illustrate a point.

The Clock and the Camshaft by John W. Farrell
The Clock and the Camshaft: And Other Medieval Inventions We Still Can't Live Without - John W. Farrell

TITLE:  The Clock and the Camshaft: And Other Medieval Inventions We Still Can't Live Without

 

AUTHOR:  John W. Farrell

 

DATE PUBLISHED:  2019

 

FORMAT:  Hardcover

 

ISBN-13:  9781633885721

__________________________

DESCRIPTION:

"This history of medieval inventions, focusing on the eleventh to the fourteenth centuries, vividly portrays a thriving era of human ingenuity—and the results are still being felt to this day. From the mechanical clock to the first eyeglasses, both of which revolutionized society, many of the commonplace devices we now take for granted had their origin in the Middle Ages. Divided into ten thematic chapters, the accessible text allows the reader to sample areas of interest or read the book from beginning to end for a complete historical overview.

A chapter on the paper revolution shows that innovations in mill power enabled the mass production of cheap paper, which was instrumental in the later success of the printing press as a means of disseminating affordable books to more people. Another chapter examines the importance of Islamic civilization in preserving ancient Greek texts and the role of translation teams in Sicily and Spain in making those texts available in Latin for a European readership. A chapter on instruments of discovery describes the impact of the astrolabe, which was imported from Islamic lands, and the compass, originally invented in China; these tools plus innovations in shipbuilding spurred on the expansion of European trade and the later age of discovery at the time of Columbus.

Complete with original drawings to illustrate how these early inventions worked, this guided tour through a distant era reveals how medieval farmers, craftsmen, women artisans, and clerical scholars laid the foundations of the modern world.

Maps of the Ancient Sea Kings by Charles Hapgood
Maps of the Ancient Sea Kings: Evidence of Advanced Civilization in the Ice Age - Charles H. Hapgood

TITLE:   Maps of the Ancient Sea Kings: Evidence of Advanced Civilization in the Ice Age

 

AUTHOR:  Charles H. Hapgood

 

DATE PUBLISHED:  2014 (originally 1965)

 

FORMAT:  Paperback

 

ISBN-13:  9780932813428

________________________

DESCRIPTION:

 

Charles Hapgood s classic 1966 book on ancient maps is back in print after 20 years. Hapgood produces concrete evidence of an advanced worldwide civilization existing many thousands of years before ancient Egypt. He has found the evidence in many beautiful maps long known to scholars, the Piri Reis Map that shows Antarctica, the Hadji Ahmed map, the Oronteus Finaeus and other amazing maps. Hapgood concluded that these maps were made from more ancient maps from the various ancient archives around the world, now lost. Hapgood also concluded that the ancient mapmakers were in some ways much more advanced scientifically than Europe in the 16th century, or than the ancient civilizations of Greece, Egypt, and Babylonian. Not only were these unknown people more advanced in mapmaking than any people prior to the 18th century, it appears they mapped all the continents. The Americas were mapped thousands of years before Columbus. Antarctica was mapped when its coasts were free of ice. There is evidence that these people must have lived when the ice age had not yet ended in the Northern Hemisphere and when Alaska was still connected with Siberia by the Pleistocene, ice age land bridge.

A fascinating analysis of several old maps and what the results ultimately mean.
