Did You Know {103} ~ How Far Can A Dog Hear?

Sounds have waves. The frequency of sound is how close together the sound waves are. The closer together the waves, the higher the frequency or pitch. You can think of this like the beach during a storm, when waves hit the beach more often.

Dogs and people hear about the same at low frequencies of sound (around 20Hz). This changes at high frequencies of sound, where dogs hear up to 70-100kHz, much better than people at only 20kHz. Dogs hear sound frequencies at least three times as high compared to people.

You may have wondered how those special silent dog whistles work? They make high-frequency sounds that dogs can hear but we can’t. Because dogs can hear higher frequencies than us, there are a lot more sounds for dogs to hear.

They can also hear sounds that are softer or farther away, as far as a kilometre. That means dogs can be more sensitive to loud sounds. This is why some dogs are scared of fireworks or thunderstorms. It is also why a dog might bark at a sound you cannot hear.

Did You Know {90} ~ When One Rule Seems Too Strict, We Want To Break More

Psychologists have studied a phenomenon called reactance: When people perceive certain freedoms being taken away, they not only break that rule, but they break even more than they otherwise would have in an effort to regain their freedom. This could be one of the best psychology facts to explain why a teenager who can’t use his phone in class will chew gum while stealthily sending a text.

Symbols {1} ~ Ouroboros

The name Ouroboros is Greek in origin. Oura means tail while Boros is translated as eating. Taken together, it means ‘tail devourer’ or ‘one who eats the tail’. As a symbol, it depicts a serpent consuming its own tail.

The Ouroboros is one of the world’s most ancient mystical symbols, having appeared in Egypt as early as 1600 BC. It was adopted by the Phoenicians and later the Greeks, who gave it its name. Over the centuries it has been subject to several interpretations by different cultures. One is that it represents the Universe’s eternally cyclic nature, which creates life out of destruction. In alchemy, it symbolizes the continuous renewal of birth and death that alchemists struggle to break free from. Gnosticism and Hermeticism also hail the Ouroboros as representative of cyclical natural life and the unity of opposites. Gnostics, in particular, regard it as a sign of the transcendence of duality and a connection to Abraxas, the solar god.
