The planets’ rotation around the sun or shift workers switching between night and day our time is shaped by a variety of spinning events. Some of them occur daily and some are unpredictable and irregular.
Precession is one of these rotational events that occur more frequently. It is the Earth’s slow wobble on its rotational axis. This wobble is comparable to an off-center rotating toy top. This angular shift in relation to fixed stars (inertial space) is a period of 25,771.5 years. It also explains why fun park voyages such as Ferris wheels and carousels must be constructed using a sturdy side-toside bar referred to as an axle. Another typical rotational event is a Coriolis effect, a mystical push over a freely going body system that influences its revolving movements on an atmospheric scale. This is the reason for a wide variety of weather conditions, including the alternating directions of rotation of cyclones within the Upper and Southern hemispheres.
Many people are unaware that the speed at which the earth rotates can change. The days can sometimes appear longer or shorter than they need to be. The atomic clocks, that maintain the same time for all, must be fine-tuned periodically. This kind of change is known as a leap second. This article will discuss what it is and why it is important to our lives.
