In the Sky: Designs Inspired by Nature

In the Sky: Designs Inspired by Nature
Harriet Evans, illustrated by Gonçalo Viana

Yet again, prepare to be awed by nature. This time at the way scientists and technologists have been inspired by things in the natural world, both animal and plant, as described in this book.

Did you know for example that the Wright brothers were inspired in part by pigeons when they designed and flew their first successful plane; or that the wingtips of the Airbus A350 XWB are curved like a bird to help it fly faster?
As well as such information, readers can learn how forces affect the speed of flying objects, be they birds or aeroplanes.

I was fascinated to read that the Japanese engineer Eiji Nakatsu was an avid bird watcher and when faced with the challenge of lessening the noise of the Shinkansen bullet train, he took inspiration from the Adélie penguin for the bottom half of the pantograph (device connecting the train to the overhead wires), and was able to make it more streamlined.

Architects too, have used nature as designer to influence creations such as the apartment building, Arbre Blanc in France, while Vietnamese architects have covered the roofs of some houses with trees to help lower the temperature of the locality and improve air quality. Other architects have drawn upon the hexagon shapes created by bees’ honeycombs in designs including the British HiveHaus homes, while the Slovenian social housing in Izola comprises hexagonal modules and the Sinasteel skyscraper in Tianjin, China will have hexagonal windows.

I was interested to learn scientists have copied the rough coating of moths’ eyes, using microscopic bumps on the surfaces of phone screens and other electronic devices to reduce glare;

while in the USA designers have created special screens for such devices, which bend light like butterfly wings. Amazing.

All this and other intriguing topics are covered in Harriet Evan’s text. Gonçalo Viana’s dramatic illustrations make it all the more alluring, exciting and imagination stirring. There’s a glossary too and I love the endpapers.

All in all, a super STEM book.
