How did people learn to fly, glow in the dark, and land on the Moon? By going back to the beginning.
Axi is back — and this time the big questions are about building, creating, and solving problems no one had ever solved before. In three time-travel adventures, curious kids meet three of history's boldest thinkers and discover the method behind every great invention — First Principles Thinking: instead of copying what others did, you go back to the beginning and figure out what MUST be true.

Marie Curie works in a tiny, leaky shed and refuses to accept what other scientists assumed — measuring everything herself until a mysterious glow changes science forever.
The Wright Brothers ignore everyone else's failed flying machines, study the birds instead, and test 200 wing shapes to lift humans into the sky.
Margaret Hamilton and the Apollo team break an "impossible" problem into small, solvable pieces — and put people on the Moon.

Along the way, young readers learn The Builder's Three Rules: follow the mystery, try-fail-learn-repeat, and break big problems down and work together.
Perfect for curious kids ages 8-10 who love science, invention, and asking "but WHY?" — and for parents and teachers who want to raise confident problem-solvers.
The Little Philosophers series teaches kids HOW to think, not what to think — using First Principles Thinking, one big idea at a time:

Book 1: How to Ask Big Questions — the art of curiosity and philosophy
Book 2: How Machines Think — computers, code, and smart machines
Book 3: How People Build Amazing Things — discovery, flight, and reaching the Moon

Each book stands alone, but together they build a complete thinking toolkit for young minds.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
