Our day is shaped by many spinning events, be it the rotation of the planets around the sun or the shift workers changing between night and day shifts. Some occur every day, while others can be unpredictable and irregular.
Precession is one of the periodic events that happen more frequently. It is the Earth’s gradual wobble on its axis of rotation. This wobble is similar to an off-center rotating toy top. The variation in the rotational direction to fixed stars, or inertial space, has an entire cycle of 25,771.5. This is the reason Ferris wheels and carousels as well as other fun rides have to be equipped with a solid bar that runs from side to side. An axle is a Coriolis effect is a second rotating phenomenon. It is a mystical force that pushes the freely moving body system that influences its revolving movement on a weather scale. This is responsible for a wide variety of weather conditions patterns, which includes the alternating directions of cyclones that occur in the Upper and Southern hemispheres.
Many people are unaware of the fact that the speed at which the earth rotates can alter. Sometimes, days appear longer or shorter than they need to be. The atomic clocks, which maintain an uniform time, need to be tuned regularly. This kind of change is referred to a leap second, and this article will describe how it happens and what it means to our everyday lives.
