Earth does not rotate at exactly the same speed every day. Although we commonly think of a day as a fixed 24-hour period, the planet’s rotation varies by tiny amounts because Earth is a dynamic system made of a solid crust and mantle, a moving liquid outer core, oceans, atmosphere, ice, groundwater, and other components.That is why scientists sometimes record days that are slightly shorter than 86,400 SI seconds. On June 29, 2022, for example, Earth completed a rotation about 1.59 milliseconds faster than a standard 24-hour day. It was the shortest day recorded in the modern atomic-clock era, according…

The Habsburg chin is a popular term for the distinctive lower-face appearance associated with members of the Habsburg dynasty, one of Europe’s most influential royal families. It is often discussed alongside the better-known expression “Habsburg jaw,” a historical term associated with a prominent lower facial profile. Although portraits of Habsburg rulers clearly show recurring facial characteristics, modern research gives the subject more nuance than the popular story suggests. The appearance cannot simply be reduced to a single “Habsburg gene,” nor can every prominent chin be attributed to the dynasty. Researchers have examined historical portraits to distinguish mandibular prognathism, or forward…
If you have ever wondered what is wet shaving, the answer is simpler than it may sound.

Wet shaving can mean using a standard cartridge razor with shaving gel, but the term is also commonly associated with traditional shaving equipment such as safety razors, straight razors, shaving brushes, and shaving soaps. These are related approaches,…
