Whether it’s the planets rotating around the sun, or shift workers that switch between day and night alterations our time is shaped by a myriad of events. Some of them happen daily, while others are more irregular and unpredictable.
Precession is one of these periodic events that happen more regularly. It is the Earth’s slow wobble around its axis. This wobble is comparable to the slightly off-center rotation of a toy top. This angular shift in relation to fixed stars (inertial space) has a time lapse https://northcentralrotary.org/2019/11/16/rotating-events-in-our-time/ of 25,771.5 years. This is also the reason why amusement parks like ferris wheels and carousels need to be constructed with a solid side-to-side bar called an axle. Another common rotating event is the Coriolis effect that is a mystical push across a freely moving body system that alters its revolving movements on an astronomical scale. This is responsible for many weather patterns, including the alternating directions of cyclones on the upper and southern hemispheres.
Although most people are aware that the Earth rotates around its axis 24 hours a day However, many don’t know that the speed of this rotation can vary. Days can appear to be longer or shorter than they ought to be. This is why the atomic clocks which maintain standard time have to be tuned periodically. This kind of change is referred to as a leap second. This article will explain what it is and the significance of it to our lives.
