Russian popular-science writer Yakov Perelman makes physics fun in his classic book, offering real-world applications, demonstrations, and fascinating phenomena that remain relevant-and educational-to modern readers. This book explains many of the most entertaining aspects of the physical world and its principles, including optical illusions, light tricks and mirages, watermelon force, gravity and flight, travel to the moon, brain teasers, heat, boomerangs, "perpetual motion machines," echoes, and feats of strength.

Presented by Quid Pro Books as a Digitally Remastered Book, (TM) this edition is unlike vintage republications that repeat printer errors or copying artifacts from the original. Instead, the process markedly reduces underlines, blotches, stray marks, and broken words. The effect retains and preserves the original presentation and its accuracy (unlike all-new renderings which introduce scan/OCR error), while offering a more complete and pleasant reading experience . . . to a new generation of students and curious readers.
