In order to get more accurate results, our search has the following Google-Type search functionality:
If you use '+' in front of a word, then that word will be present in the search results.
ex: Harry +Potter will return results with the word 'Potter'.
If you use '-' in front of a word, then that word will be absent in the search results.
ex: Harry -Potter will return results without the word 'Potter'.
If you use 'AND' between two words, then both of those words will be present in the search results.
ex: Harry AND Potter will return results with both 'Harry' and 'Potter'.
If you use 'OR' between two words, then bth of those words may or may not be present in the search results.
ex: Harry OR Potter will return results with just 'Harry', results with just 'Potter' and results with both 'Harry' and 'Potter'.
If you use 'NOT' before a word, then that word will be absent in the search results.
ex: Harry NOT Potter will return results without the word 'Potter'.
Placing '""' around words will perform a phrase search. The search results will contain those words in that order.
ex: "Harry Potter" will return any results with 'Harry Potter' in them, but not 'Potter Harry'.
Using '*' in a word will perform a wildcard search. The '*' signifies any number of characters. Searches can not start with a wildcard.
ex: Pot*er will return results with words starting with 'Pot' and ending in 'er'. In this case, 'Potter' will be a match.
Smartphones, skyscrapers, spacecraft. Modern technology seems mind-bogglingly complex. But beneath the surface, it can be beautifully simple.
In Nuts and Bolts, award-winning engineer and broadcaster Roma Agrawal 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.
Tracing the surprising journeys of each invention through the millennia, Roma reveals how handmade Roman nails led to modern skyscrapers, how the potter's wheel enabled space exploration, and how humble lenses helped her conceive a child against the odds.
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.
