Our daily schedule is shaped by many spinning events, whether it’s the cyclic motion of the sun’s planets or shift workers switching between evening and day shifts. Some occur daily, while others are more irregular and less predictable.

Precession is among these rotational events that occur more regularly. It is the Earth’s gradual wobble on its rotational axis. The wobble is similar to the slightly off-center rotation of a toy top. This varying rotational angle in relation to fixed stars, or inertial space, has an entire cycle of 25,771.5. This is why Ferris wheel, carousels and other fun rides in parks must be equipped with a solid bar that runs from side to side. Another typical rotational event is the Coriolis effect, a mysterious push over a freely moving body system which influences its revolving movement on an astronomical scale. This is the reason for a wide range of weather conditions patterns, including the alternating directions of rotation of cyclones that occur https://northcentralrotary.org/2019/10/13/an-international-organization/ in the Upper and Southern hemispheres.

A lot of people are unaware that the speed at which the earth rotates can alter. The days can sometimes appear longer or shorter than they should be. This is why the atomic clocks which maintain standardized time have to be periodically adjusted. This type of change is known as a leap second, and this article will explain how it happens and the importance it has to our everyday lives.
