"In 2011, without warning, a skyscraper in South Korea began to shake uncontrollably and was immediately evacuated. Was it an earthquake? A terrorist attack? No one seemed quite sure. The actual cause emerged later: Twenty-three middle-aged Koreans were having a Tae Bo fitness class in the office gym on the twelfth floor. Their beats had inadvertently matched the building's natural frequency, and this coincidence caused the building to shake at an alarming rate for ten minutes. Frequency is all around us,but really isn't understood. What the Ear Hears (and Doesn't) reveals the extraordinary world of frequency-from medicine to religion to the environment to the paranormal-not through abstract theory, but through a selection of small memorable human (and animal) stories laced with dry humor, including: The elephant who anticipated the 2004 Asian tsunami and carried a young girl miles inland, saving her life The reason for those deep spiritual feelings we have in churches The cutting-edge methods that are changing medicine The world's loneliest whale"--,Provided by publisher.

"For listeners of Neil deGrasse Tyson and Bill O’Neill, What the Ear Hears (and Doesn’t) is a fascinating science book for adults that explores the physics principle of frequency and the (sometimes weird) role it plays in our everyday lives. What do the world’s loneliest whale, a black hole, and twenty-three people doing Tae Bo all have in common? In 2011, a skyscraper in South Korea began to shake uncontrollably without warning and was immediately evacuated. Was it an earthquake? An attack? No one seemed quite sure. The actual cause emerged later and is utterly fascinating: Twenty-three middle-aged folks were having a Tae Bo fitness class in the office gym on the twelfth floor. Their beats had inadvertently matched the building’s natural frequency, and this coincidence―harnessing a basic principle of physics―caused the building to shake at an alarming rate for ten minutes. Frequency is all around us, but little understood. Musician, composer, TV presenter, and educator Richard Mainwaring uses the concept of the Infinite Piano to reveal the extraordinary world of frequency in a multitude of arenas―from medicine to religion to the environment to the paranormal―through the universality of music and a range of memorable human (and animal) stories laced with dry humor. Whether you’re science curious, musically inclined, or just want to know what a Szechuan pepper has to do with physics, What the Ear Hears (and Doesn’t) is an immensely enjoyable book filled with “did you know?” trivia you’ll love to share with friends."--,Provided by Amazon.
