Award-winning structural engineer Roma Agrawal visits Google to
discuss her book “Nuts and Bolts: Seven Small Inventions That
Changed the World in a Big Way.” The book takes readers on a deep
dive into the seven most basic building blocks of engineering that
have shaped the modern world.
From the physics behind both Roman nails and modern skyscrapers, to
rudimentary springs that inspired lithium batteries, Agrawal shows
us how even the most sophisticated items are built on the
foundations of these ancient and fundamental breakthroughs in
engineering. She deconstructs our most complex feats of engineering
into seven fundamental inventions: the nail, spring, wheel, lens,
magnet, string and pump. Each of these objects is itself a wonder
of design, the result of many iterations and refinements. Together,
they have enabled humanity to see the invisible, build the
spectacular, communicate across vast distances, and even escape our
planet.
She invites us to marvel at these small but perfectly formed
inventions, sharing the stories of the remarkable, and often
unknown, scientists and engineers who made them possible. The nuts
and bolts that make up our world may be tiny, and are often hidden,
but they've changed our lives in dramatic ways.
