Our time is shaped by numerous rotating events, whether it's the rotation of the sun's planets or shift workers shifting between night and day shifts. Some of them occur daily and some are unpredictable and irregular.

One of these more frequent rotational events is precessionthe Earth's progressive wobble on its axis of rotation, similar as a slightly off-center rotating toy top. This variation in rotation in relation to fixed stars, also known as inertial space, has an interval of 25,771.5. It also explains why amusement park rides like ferris wheels and carousels need to be built with a solid side-toside bar referred to as an axle. A Coriolis effect is a different rotational event. It is a mysterious force that sways a moving body system, which affects its revolving motion on a climatic scale. This is review the reason for a wide range of weather conditions, including the alternating rotational directions of cyclones in the Upper and Southern hemispheres.

Although most people are aware that the earth rotates on its axis throughout the day but many are unaware that the speed of this rotation fluctuates. Days can appear to be longer or shorter than they need to be. The atomic clocks, that maintain a standardized time, must be tuned periodically. This type of change is referred to a leap second, and this article will discuss how it happens and why it matters to our daily lives.
