Read with my son at bedtime over the course of a month or so... really fascinating and kind of humbling for me, having somewhat naively expected to be at least aware of most of the 100 unknown things in the book... For children and adults it not only introduces you to new, hidden ideas about history, maths and science, but it also infuses your consciousness with curiosity and ignites your imagination. Think of it as a curiosity booster!

What IS that in Michelangelo's David's hand? If the sphinx isn't actually a sphinx, what on earth is it? What happened to that massive Cambodian civilisation? Just how colossal can the colossal squid get? Wha-? A made up disease saved the lives of Jewish people in 1940's Italy... woah.

Covers a lot of lesser-known facts. A few that stood out: the Sphinx in Egypt originally had its own name and mythology, but colonisation made the Roman-mythology name "Sphinx" the one that stuck; the Spanish burned Maya libraries after Catholicism was introduced; and there are natural phenomena like the Batagaika Crater, which keeps expanding every year, and Poland's "Crooked Forest."

This whole "100 Things" series from Usborne always sends me down a Google rabbit hole afterward, and I genuinely enjoy that. I want to read more from this series.

These have long been my son's favorite books, and I've had so much fun reading them with him over the years. This one included a couple of things that really disappointed/frustrated me, but ignoring that, it was another great installment. So many fun things to learn about (and then look up to learn about more!)

Another good one! Amelia Earhart, prime numbers (so scary, didn’t know so much reliance from banks), syndrome K during world war 2, the Spanish burned all but 4 Mayan books, museums not displaying everything in their collection, and undiscovered all the things!

I mean there weren’t very many answers in here, but the format is great with illustrations on each page. It did set off some rabbit holes for me when I wanted to learn more about a specific fact.
