Whether it’s the planets rotating around the sun, or shift workers switching between night and day the way we live our lives is shaped by a myriad of events. Some of them happen daily, while others are more irregular and unpredictable.
Among these more regular rotating events is precession -the Earth’s progressive wobble on its axis of rotation, just like a slightly off-center spinning toy top. This varying rotational angle in relation to fixed stars, also known as inertial space, is an extended period of 25,771.5. This explains why fun park voyages such as Ferris wheels and carousels have to be built with a solid side-to-side bar called an axle. Another typical rotational event is the Coriolis effect, a mysterious push across a freely moving body system which influences its revolving movement on an astronomical scale. This is responsible for a myriad of weather conditions, including the alternating directions of rotation of cyclones within the Upper and Southern hemispheres.
While the majority of people are aware that the planet rotates on its axis throughout the day, many aren’t aware that the speed of this rotation can vary. The days can sometimes appear longer or shorter than they actually be. That’s why the atomic clocks that maintain a standard time have to be fine-tuned occasionally. This kind of adjustment is known as a leap second. This article will discuss the meaning behind it and the significance of it to our lives.
