This book addresses ten common "whys" in everyday life and provides scientific answers. For example, raw eggs shouldn't be eaten, cups buzzing in the ears, and reading in cars shouldn't be allowed. Each "why" is followed by corresponding scientific explanations, including common sense on egg consumption, the principles of sound, car safety, and the importance of handwashing.
