The Science of Spin

Just finished reading "The Science Of Spin - How Rotational Forces Affect Everything from Your Body to Jet Engines to the Weather" by Roland Ennos, released by Scribner.
Without spin the universe and life would not exist as we know it. In "The Science Of Spin," Ennos explores the effects of spin in three areas – the planet, technology, and the human body – with a writing style that forgoes equations in favor of approachable diagrams and explanations.
The planet section covers solar system formation, planetary orbits, weather patterns, tides, and magnetic fields. At first, I wondered what spin has to do with magnetic fields, but it turns out that their interaction keeps us from dying from solar radiation. The Earth’s spin creates deep molten currents of magnetic material, producing an enveloping field that shields us from the sun’s bombardment and also creates beautiful auroras.
The technology section tracks how spinning equipment evolved and expanded into society over time, from drop spindles to airplanes. A big focus is the use of rotating wheels to power machines, first by water, then steam, and finally electricity. Ennos shows how improvements in incorporating spin in machinery advanced the industrial revolution.
How humans stand, walk, run, throw, hit, and twist with rotation and spin is explored in the third section of Ennos' book. Our joints allow such flexibility of motion that we can balance and propel objects with surprising efficiency, never mind the astounding accomplishments of athletes.
Oddly, Ennos believes that an over reliance on math has prevented most scientists from fully exploring and appreciating the importance of spin and how the universe revolves and exists because of it.
