Is there a global theory for the shapes of fishes? Probably the most famous pages of his book are the ones about fish shapes:. Stretch one kind of fish, and it looks like another.

On growth and form

The book is long — pages in the first edition of , pages in the second edition of The book covers many topics including the effects of scale on the shape of animals and plants, large ones necessarily being relatively thick in shape; the effects of surface tension in shaping soap films and similar structures such as cells; the logarithmic spiral as seen in mollusc shells and ruminant horns; the arrangement of leaves and other plant parts phyllotaxis ; and Thompson's own method of transformations, showing the changes in shape of animal skulls and other structures on a Cartesian grid. The work is widely admired by biologists, anthropologists and architects among others, but less often read than cited. Philip Ball and Michael Ruse , on the other hand, suspect that while Thompson argued for physical mechanisms, his rejection of natural selection bordered on vitalism. D'Arcy Wentworth Thompson 's most famous work, On Growth and Form was written in Dundee, mostly in , but publication was put off until because of the delays of wartime and Thompson's many late alterations to the text. At a time when vitalism was still being considered as a biological theory, he advocated structuralism as an alternative to natural selection in governing the form of species, with the smallest hint of vitalism as the unseen driving force. Thompson had previously criticized Darwinism in his paper Some Difficulties of Darwinism.

On Growth and Form (1917), by Sir D'Arcy Thompson

Qty :. Scottish zoologist D'Arcy Wentworth Thompson's visionary ideas in On Growth and Form continue to evolve a century after its publication, aligning it with current developments in art and science. Practitioners, theorists, and historians from art, science, and design reflect on his ongoing influence. Overall, the anthology links evolutionary theory to form generation in both scientific and cultural domains.

Skip navigation. This substantial book is still in print today, and merited an editorial review and introductory essays by two important twentieth century biologists, John Tyler Bonner and Stephen Jay Gould. Growth and Form was immediately well-received for both its literary style and its scientific significance, as discussed by the biologist Sir Peter Medawar. Despite being almost continuously in print since its first publication, the exact influence of Growth and Form on the biological sciences, although widely acknowledged, is yet difficult to characterize. In this work Thompson aimed to unite physics and biology through an analysis of the physical limitations to the growth and structure of organisms.

In this elegantly written book, he advanced his main thesis: that biological form can reflect physical and mathematical principles. For instance, the spicules of sponges adopt a number of characteristic shapes. Thus, the initial conditions might well reflect some aspect of natural selection, but the resulting morphology of the spicules did not. One clear demonstration of his notions of the dynamic influence of starting conditions lies in the morphology of shells and horns. For instance, geometrical rules of packing determine cell arrangements.

 Мне неприятно тебе это говорить, - сказал Стратмор, - но лифт без электричества - это не лифт. - Вздор! - крикнул Хейл.  - Лифт подключен к энергоснабжению главного здания. Я видел схему. - Да мы уже пробовали, - задыхаясь, сказала Сьюзан, пытаясь хоть чем-то помочь шефу.  - Он обесточен.

Остановка поисков ключа Цифровой крепости высвободила бы достаточно энергии для срабатывания дверных замков. - Успокойся, Сьюзан, - сказал Стратмор, положив руку ей на плечо. Это умиротворяющее прикосновение вывело Сьюзан из оцепенения. Внезапно она вспомнила, зачем искала Стратмора, и повернулась к. - Коммандер. Северная Дакота - это Грег Хейл.
