Five Historic Female Mathematicians You Should Know No one can know who was the first female mathematician, but Hypatia was certainly one of the earliest. She was the daughter of Theon, the last known member of the famed library of Alexandria, and followed his footsteps in the study of math and astronomy. She collaborated with her father on commentaries of classical mathematical works, translating them and incorporating explanatory notes, as well as creating commentaries of her own and teaching a succession of students from her home. Hypatia was also a philosopher, a follower of Neoplatonism, a belief system in which everything emanates from the One, and crowds listened to her public lectures about Plato and Aristotle.
Pages — Beyond Weather & The Water Cycle Why there is no such thing as empty space MacGregor Campbell, contributor Could the universe have appeared out of nothing? In a previous video, we argued that typical notions of 'something' and 'nothing' don't really make sense according to modern physics. In our latest animated explainer, we pick up where we left off and look at whether true nothingness is possible according to physics. You can find out more about the void in our full-length feature: Nothingness: The turbulent life of empty space. For more mind-bending physics, check out this explainer on how to build a time machine, or visit our archive of One-Minute Physics videos.
Giant Pandas Sign up to get panda news from the Zoo. Giant pandas are black and white bears that live in temperate-zone bamboo forests in central China. Among the best recognized—but rarest—animals in the world, they have come to symbolize endangered species and conservation efforts. Giant pandas Mei Xiang and Tian Tian are at the National Zoo under a Giant Panda Cooperative Research and Breeding Agreement, signed in January 2011, between the Zoo and the China Wildlife Conservation Association. Seeing Pandas at the Zoo Giant panda cub Bao Bao is now on exhibit! The panda house at the David M. Visitors will be allowed into the panda house on a first-come-first-served basis. Due to the expected number of visitors to see Bao Bao, Asia Trail will be open to one-way traffic only. Visitors will enter the panda house from the west entrance, by the red panda exhibit, and exit the east entrance. It was an exciting day at the David M.

Culture Vaults : Resonant Frequencies and the Human Brain One of the great revelations of 20th century science is that all existence can be broken down into simple wave functions. Every photon, energy emission, and elementary particle rings with its own unique wave signature. When we see a color, we are actually seeing a distinct frequency of visible light. By studying the way that waves interact with other waves, researchers have found that even low-powered oscillations can have enormous effects on standing waves, physical structures, and even the human brain. Tesla first realized the massive potential of resonant waves in 1898 when he performed a simple experiment with an electromechanical oscillator the size of an alarm clock. In a later experiment using the same principle, Tesla clamped an oscillator to one of the exposed ground floor beams of a half built ten-story steel building. "The principle cannot fail," Tesla would say. Monroe's Big Discovery The Neural Radio Entrain Your Brain Well boys and girls, there you have it.
