The word "radio" comes from the Latin word "radius," which means "ray" or "beam." It originally referred to the transmission of signals by electromagnetic waves, like rays spreading out from a source. Over time, "radio" became the term for the technology and devices that send and receive these signals.

Giraffes are 30 times more likely to get hit by lightning than people. True, there are only five well-documented fatal lightning strikes on giraffes between 1996 and 2010. But due to the population of the species being just 140,000 during this time, it makes for about 0.003 lightning deaths per thousand giraffes each year. This is 30 times the equivalent fatality rate for humans.

Swallowing Reflex on the Edge

Swallowing is a complex neuromuscular coordination that must work perfectly dozens of times a day. At this moment, the palate closes the nasopharynx, and the larynx rises to meet the epiglottis.

If this timing is disrupted by even a fraction of a second, food goes down the "wrong pipe." Our anatomy literally requires us to have perfect synchronization every few seconds, or we cut off our own oxygen.

This phenomenon, known as infanticide, is aimed at establishing the genetic lineage of the new leader and maintaining his position in the pack. However, not all alpha males are so violent and may even protect and nurture the offspring of the previous leader, especially if they are related to them by blood ties.

Myth: Glass flows over time, making old windows thicker at the bottom.

Fact: Glass is an amorphous solid, meaning its atoms are arranged randomly, not in a pattern like crystals. It stays solid at all normal temperatures and only softens above 600°C (1112°F). Old windows are thicker at the bottom because of how they were made, not because glass moves.
