The Traditional Practice of the Japanese Geisha

Japanese geishas, referred to as “geiko” (pronounced “gay-ko”) first appeared 300 years ago during the Edo period, an era when Japan was closed to the rest of the world allowing its indigenous culture to flourish. There were once 80,000 geisha but that number has dropped to just 1000 during the modern day. It takes 5 long years to become a geisha, this time spent with no smartphone, no romantic relationships, and only 2 days off per month. Geishas undergo lessons in music and dance as well as tea making and etiquette. All food and lodging is provided by the geisha training institution so that students become completely and totally immersed within the geisha lifestyle. Geishas wear white masks of makeup as symbolism that what is concealed is more desirable than that which is revealed. Pink is painted onto the earlobes as a way to hide embarrassment from blushing, and bare skin is left in a “W” or “V” shape upon the back of the neck to accentuate the neck which is considered highly beautiful, sexual, and erotic in Japanese culture. Geishas are only supposed to entertain their client with highly cultured activities, and the profession is not supposed to be associated with sexual interaction

The Advent and Original Intent of Intelligence Quotient​ Examinations

Intelligence quotient examinations were invented by the French psychologist Alfred Binet as a way of measuring and identifying skill sets which children had or had not yet developed during their adolescence. The idea was to calculate the mental age divided by the chronological age to determine whether a child was ahead or behind their peer group

The Evolution of Primitive and Sophisticated Neural Networks

The human brain has 100,000,000,000,000 (100 trillion) connections and 86,000,000,000 (86 billion) neurons, which is more connections and neurons than there are stars in the Milky Way Galaxy. Ironically, the majority of the most successful creatures on Earth do not have a brain; organisms like plants, coral, and jellyfish. The sea squirt is a primary example as it has just 200 neurons, allowing it only to perceive and display simple interaction with the environment by sensing light and moving its flagellum. The sea squirt moves around until it finds a rock, then it dumps its tail and uses those once dedicated neurons for different applications, staying anchored to this spot for the rest of its life. Neurons were originally designed to allow for simple motion and movement, but as evolution progressed steadily, neural networks began to build and design intelligent life which is capable of consciousness and a sense of self but also more abstract concepts like art, mathematics, and science
