How we know the Earth is a globe—and how big it is
This concise volume presents the key ideas and classic experiments that establish the Earth as a round body. It ties together historical observations with careful measurements, showing how scientists proved roundness, measured gravity, and estimated the planet’s density.
The book walks you through early debates about flat Earth ideas, then follows the reasoning and data that led to the modern view. It describes practical methods for weighing the Earth and determining its mass, using torsion balances, common balances, and long baseline measurements. Through clear explanations and historic experiments, you’ll see how theory and measurement work hand in hand.
- How celestial observations support a spherical Earth, including how the pole star and horizon behave with travel northward
- Key experiments that measured gravitational pull and density, such as Cavendish-type work and later balance-based tests
- Methods used to compare different measurement approaches and verify results
Ideal for readers curious about the science of the Earth and the methods scientists use to test big ideas.

Store description
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 visit 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.…
