When we think of the Fascinating World of Engineering, we often imagine complex machines and structures that seem beyond our understanding. But in her book Nuts and Bolts, structural engineer Roma Agrawal takes us on a journey through the fundamental elements that make up the modern world.
Agrawal begins by updating the classic list of simple machines – the lever, wheel and axle, pulley, inclined plane, wedge, and screw – with seven elements that she argues form the basis of engineering today: the nail, wheel, spring, magnet, lens, string, and pump. Through precise yet simple descriptions and hand-drawn diagrams, she breaks down each element’s operating principles and shows how they are used in various technologies.
But this book is more than just a scientific guide. It is a captivating narrative filled with characters driven by hunger, frustration, curiosity, compassion – or even spite. We meet familiar names like Alexander Graham Bell but also learn about forgotten pioneers such as Arab polymath Ibn al-Haytham who established optics principles essential for designing lenses.
Agrawal also highlights the often overlooked contributions of minoritized people in engineering. From Mongolian archers who perfected their bows using different materials to a 19th century American housewife who invented an automatic dishwasher out of frustration with her staff breaking her fancy dishes – these stories showcase the diversity and ingenuity within the field of engineering.
One standout chapter tells the story of Josephine Cochran who received a patent for her automatic dishwasher in 1886. Her invention was based on cogs derived from wheels – a testament to how these fundamental elements continue to shape modern technology.
But Agrawal’s own experiences as an engineer also shine through in the book. From her time at a blacksmith’s forge to undergoing IVF treatment, she brings a personal touch to the stories and makes them relatable to readers of all backgrounds.
Nuts and Bolts is a celebration of engineering and its impact on our world. It reminds us that behind every invention, there are people with unique perspectives and stories. Whether you are a STEM enthusiast, career planner, or simply curious about the world around you, this book is a must-read for anyone interested in the fascinating world of engineering.
