50 Women Who Changed the World A list of famous influential women, including women’s rights activists, poets, musicians, politicians, humanitarians and scientists. Sappho (circa 570 BCE) One of the first known female writers. Much of her poetry has been lost but her immense reputation has remained. Plato referred to Sappho as one of the great 10 poets. Cleopatra (69 BCE–30 BCE) The last Ptolemaic ruler of Egypt. Mary Magdalene (4 BCE–40BCE) Accounts from the Gospels and other sources suggest Mary Magdalene was one of Jesus’ most devoted followers. Boudicca (1st Century CE) Boudicca was an inspirational leader of the Britons. Hildegard of Bingen (1098–1179) Mystic, author and composer. Eleanor of Aquitaine (1122–1204) The first Queen of France. Joan of Arc (1412–1431) The patron saint of France, Joan of Arc inspired a French revolt against the occupation of the English. Mirabai (1498–1565) Indian mystic and poet.

Mamihlapinatapai The word Mamihlapinatapai (sometimes spelled mamihlapinatapei) is derived from the Yaghan language of Tierra del Fuego, listed in The Guinness Book of World Records as the "most succinct word", and is considered[by whom?] one of the hardest words to translate. It allegedly refers to "a look shared by two people, each wishing that the other will offer something that they both desire but are unwilling to suggest or offer themselves."[1] A slightly different interpretation of the meaning also exists: "It is that look across the table when two people are sharing an unspoken but private moment. It is also referenced in Defining the World in a discussion of the difficulties facing Samuel Johnson in trying to arrive at succinct, yet accurate, definitions of words.[5] In popular culture[edit] The word and its definition was the title of a groundbreaking exhibition by Max Pinckers and Michiel Burger in Amsterdam's Flemish Cultural Centre De Brakke Grond in 2012.

15 Awesome Chemistry GIFs You don’t need to watch Breaking Bad to know that chemistry is pretty awesome. Below, we explore our favorite 15 chemistry GIFs and the science behind them (when we could figure it out): Melting Metal With Magnets The Science: The copper wire has a significant amount of AC electricity running through it, causing it to act like a really strong electromagnet. In the metal slug, eddy currents form due to the magnetic field the copper wire is causing while the copper wire has high frequency AC flowing through it. Orange LED Light In Liquid Nitrogen The Science: When an LED is immersed in liquid nitrogen, the electrons lose a lot of thermal energy, even when the light isn’t turned on. Awesome Chemistry GIFs: Heating Mercury Thiocyanate Hydrogen Peroxide Catalyzed By Potassium Iodide
6 Mind-Blowing Substances That Laugh in the Face of Physics We can laugh at our ancestors who thought gunpowder was sorcery, or rappers who don't understand what magnets are. But we're telling you right now, there are materials created by science that absolutely look like fucking witchcraft. These materials are often hard to get and/or incredibly dangerous, but they're worth it for the cool factor alone. #6. Gajitz Sure, everybody knows there's such a thing as liquid metal (mercury, duh) and that all metal will melt if you get it hot enough. Gallium melts at just past room temperature, so it isn't very useful for building anything, unless that thing is intended to be both short-lived and hilarious. Disappearing SpoonsThere is no spoon. Wait, it gets weirder. Just dab a little drop on the top of a can ... Nurd Rage ... and it will make the entire area around it brittle. Nurd Rage"Now you can open beer cans with the same ease of gouging out the eyes of those who would defy you!" Nurd Rage"A little more work, and this can could be a Fleshlight." #5. #4.

And this is what happens when you zoom out farther… And farther… Keep going… Just a little bit farther… Almost there… And here it is.
The Piasa In 1673, French missionary Jacques Marquette was exploring the Mississippi valley when he came upon a strange mural painted on a limestone bluff near what is now Alton, Ill.: While Skirting some rocks, which by Their height and length inspired awe, We saw upon one of them two painted monsters which at first made Us afraid, and upon Which the boldest savages dare not Long rest their eyes. They are as large As a calf; they have Horns on their heads Like those of a deer, a horrible look, red eyes, a beard Like a tiger’s, a face somewhat like a man’s, a body Covered with scales, and so Long A tail that it winds all around the Body, passing above the head and going back between the legs, ending in a Fish’s tail. Green, red, and black are the three Colors composing the Picture. In 1836 local settler John Russell told of a flying monster that lived in the cliffs and attacked nearby Indian villages, and the notion of wings is carried through in the reproduction above.
