Magenta isn't a thing...
Isaac Newton wasn't the first person who noticed that when light passed through a prism, it transformed into a rainbow of colors, but he was the first to figure out (roughly) why. Before him, people had supposed that the prism somehow corrupted the color of the light. Newton took that rainbow, passed it through another prism, and "re-assembled" it into its original state (white light), and deduced correctly that white light is actually made up of many different colors. He even charted it out, making a linear bar of all the colors, from red on the left to violet on the right.
But then he noticed that a popular visible color -- magenta -- was not in the spectrum. Magenta was really a combination of red and violet. So Newton took the his linear color spectrum and made it a circle,
One Does Not Simply Walk into Gehenna...Our current perceptions of Hell derive primarily from two sources: John Milton's Paradise Lost and Dante's Inferno. However, hundreds of years prior to these great works, there was Gehenna, a truly loathsome place of never-ending fire and noxious fumes that became a living metaphor for Hell on Earth.One Does Not Simply Walk into Gehenna...3 months ago in Literature

The name Gehenna is a derivation of the Valley of Hinnom, a ravine outside of old Jerusalem. Starting somewhere around 800 BC, some of the inhabitants of Judah used the valley as a place to worship Moloch, an ancient Ammonite deity. The details of the worship are pretty gruesome, so if you are squeamish, stop reading.
Followers of Moloch erected a bronze statue, depicting the god as having a bull's head and outstretched arms. The statue was hollow or had some sort of fire pit in it. Worshippers would place children to be sacrificed in Moloch's arms, where the flames would gradually consume them until they fell into the pit. There are descriptions of th

Everything you know is wrong.
That's the title of an old Firesign Theater album, and I think of it often as I watch my kids progress through high school. Maybe it should read, "Many of the things you are taught have been dumbed down because teachers didn't think you could handle them." Whether it's glossing over quantum physics when teaching the nature of the atom, or stating that Socrates killed himself, because getting into the whole trial thing is too complicated, examples abound.
Anyway...most people, when asked to name the primary colors, would respond "red, yellow, and blue", and, when asked to define what a primary color is, would respond with something like, "they are the colors which can be used to make all other colors". That's what many of us were taught in school at a young age, but it's only partially true. People involved in printing know that the truest pri
