Perspectives in Biology and Medicine

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. As he saw it, unlike physiologists, zoologists and morphologists had not applied a mathematical or physical perspective to their science. Put another way, the science of biological growth and form was not understood mathematically.

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. But just to ask the question is interesting, and On Growth and Form is full of interesting questions—together with all manner of curious and interesting answers. But he was also a diligent natural scientist, and he became a serious enthusiast of mathematics and physics.

On Growth And Form. The Complete Revised Edition By D'arcy Wentworth Thompson

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.

He was a classicist ofsufficient distinction to have become President ofthe Classical Associations ofEngland and Wales and ofScotland; a mathematician good enough to have had an entirely mathematical paper accepted for publication by the Royal Society; and a naturalist who held important chairs for sixty-four years, that is, for all but the length oftime into which we must nowadays squeeze the whole ofour lives from birth until professional retirement. He was a famous conversationalist and lecturer the two are often thought to go together, but seldom do , and the author ofa work which, considered as literature, is the equal ofanything ofPater's or Logan Pearsall Smith's in its complete mastery ofthe bel canto style. Add to all this that he was over six feet tall, with the build and carriage ofa Viking and with the pride of bearing that comes from good looks known to be possessed. D'Arcy Thompson he was always called that, or D'Arcy had not merely the makings but the actual accomplishments ofthree scholars. All three were eminent, even if, judged by the standards which he himself would have applied to them, none could strictly be called great.

On Growth and Form, first published in and then republished in by Cambridge University Press, is D'Arcy Thompson's radical departure from standard zoology. Looking outside the scope of comparative morphology and evolution, he sought to study nature from a mathematical perspective. He looked to both ancient as well as modern texts to pull together his observations on the development of form and structure in living things. The resulting text is a poetic treatise dedicated to the wonders of nature. What makes his observations so rich is his careful consideration and blending of philosophy, literature, and mathematical principle.

Никто не ответил, и Беккер толкнул дверь.  - Здесь есть кто-нибудь? - Он вошел. Похоже, никого. Пожав плечами, он подошел к раковине. Раковина была очень грязной, но вода оказалась холодной, и это было приятно. Плеснув водой в глаза, Беккер ощутил, как стягиваются поры.

Ей еще не приходилось слышать, чтобы он так. - Что значит - пробовал. Стратмор развернул монитор так, чтобы Сьюзан было. Экран отливал странным темно-бордовым цветом, и в самом его низу диалоговое окно отображало многочисленные попытки выключить ТРАНСТЕКСТ. После каждой из них следовал один и тот же ответ: ИЗВИНИТЕ. ОТКЛЮЧЕНИЕ НЕВОЗМОЖНО Сьюзан охватил озноб.

Вцепившись в левую створку, он тянул ее на себя, Сьюзан толкала правую створку в противоположном направлении. Через некоторое время им с огромным трудом удалось расширить щель до одного фута. - Не отпускай, - сказал Стратмор, стараясь изо всех сил.  - Еще чуточку. Сьюзан удалось протиснуть в щель плечо.

 - Позволь мне объяснить.  - Голос его, однако, мягче не.  - Во-первых, у нас есть фильтр, именуемый Сквозь строй, - он не пропустит ни один вирус.

    In particular, this is true for those of the chapter on the theory of transformation, which even has an impact on art and humanities.
