Mass hysteria sounds like a phrase that doesn’t actually mean anything. Today, we normally use it in the hyperbolic sense. “Everyone is freaking out over these Tickle me Elmos! It’s mass hysteria!” But, this phrase that we just kind of casually throw around is actually has some substance behind it. As it turns out, there are a bunch of actual cases of mass hysteria; cases where large groups of people suddenly, and whole heartedly, believed something to be true; to be real. Sometimes it’s silly, sometimes it’s a bit on the serious side, but when mass hysteria strikes, it’s always guaranteed be an absolute mystery.

Fog is caused by a supersaturation of the air so that it can no longer hold water vapor. This is a meteorological phenomenon where water vapor precipitates out into small droplets of fog or condensation. The process of fog formation is similar to that of cloud formation. Fog forms close to the ground rather than higher up in the atmosphere and can muffle or distort sounds as well as severely limiting visibility. These conditions are what often lead to traffic accidents during foggy weather.

When air reaches a point of extremely high humidity, fog will form. Usually a rapid cooling of the air will cause condensation to form. There are actually a variety of different types of fog that get their names from the conditions that they develop under. A light shone directly at fog will read more...

What Is The Origins Of The Black Cats Superstition?
4 months ago - 3 answers
There are a number of superstitions based on black cats and, depending where you are from, they can be good or evil omens.
The fear of a black cat crossing your path is relatively recent and in direct contradiction with the ancient Egyptian’s reverence for the animals they domesticated around 3000 BC. All cats were protected by law from injury or death in Egyptian society. These cats were occasionally mummified and entire cemeteries dedicated to cats have been unearthed by archaeologists.
In England and Europe a dread of cats – particularly black ones – developed in the Middle Ages when cities were over-run with them. Alley cats became common and old ladies often felt compassion and fed them. During the era of witch hysteria the theory evolved that these women were witches and read more...

Yes bulls are colour blind. Since the seventeenth century fighting bulls have been bred on bull ranches. The animals go through several selection processes during their first three years, in which only those with the best stamina, courage, physical appearance, and coloration are selected for eventual combat.

Bulls never receive realistic training in preparation for combat. This is because they must, for symbolic reasons, be virginal regarding actual fighting experience. Also, because of their excellent memory, experienced bulls would be apt to develop tricky tactics rather than react just on the basis of raw courage and instinct as is expected.
Like all other cattle, fighting bulls are colour blind. The myth that a bull can see the colour red, is just that, a myth. Despite most bull-fighters read more...
