There are children's questions that not every adult can answer: why is the sky dark at night? Why don't we fall through the floor? who invented the wheel? Why does the mirror only reverse left and right, not up and down? Karl Sabbagh examines in detail these and many other mysteries (yes, mysteries, and Big Science ones at that!), and not just sorts them out, but easily, intelligibly, and with good humor, talks about the wonders of physics, chemistry, biology, psychology and even cosmology that surround us . Here are some more questions: how does Google work? can neutrinos be seen? What is the fifth taste that no one knows about except the Japanese? Do dogs get angry at us? who was the author of the first cartoon in history? Interesting? It will be even more interesting while reading this book! Because that is precisely the purpose for which it was written: to remind us that the world around us is mysterious and amazing. Karl Sabbagh (b. 1942) is a British writer of Palestinian origin, writer, journalist, and television producer. Author of many popular science books, documentaries and popular science television series.
