Simplifying Radicals Using Rational Exponents
This video explains how to simplify roots that are either greater than four or have a term raised to a large number by rewriting the problem using rational exponents. Remember that every root can be written as a fraction, with the denominator indicating the root's power. When simplifying radicals, since a power to a power multiplies the exponents, the problem is simplified by multiplying all the exponents together. (1:44)

FDR and the Court
In 1937 when Elsie Parrish, a maid for the West Coast Hotels in Washington State, sued for back wages based upon the state minimum wage, her employer argued for “liberty of contract.” With the economic challenges of the Depression as a factor and in a true reversal from previous trends, the Supreme Court abandoned strict ideas regarding “free market” protectionism at the expense of individual workers and ruled on the side of Parrish. This video explores the Court’s

Science Bulletins: Kepler Discovers Dozens of Worlds
Kepler is the first NASA mission able to discover planets the size of Earth—and smaller—that are orbiting other stars. Kepler has discovered 11 solar systems and 26 planets, ranging from the size of Earth to larger than Jupiter. By searching for planets that lie within a star's habitable zone—in which a planet could maintain liquid water—the mission may locate terrestrial planets capable of supporting life.
Science Bulletins is a production of the National Center for Science Literacy, E

Vivons-nous dans un univers ou dans un multivers ?
Conférence donnée à l'IAP le 7 février 2012 par Aurélien BARRAU, astrophysicien au Laboratoire de Physique Subatomique et de Cosmologie de Grenoble.
Dans cette conférence, je proposerai une introduction simple à la cosmologie d'aujourd'hui et aux concepts physiques qui la sous-tendent. De la relativité générale à la théorie des cordes, en passant par les trous noirs et la gravitation quantique, nous en viendrons à interroger le statut de notre univers lui-même. Se pou
