Drake Equation
 Drake & Josh: Suddenly Brothers, Vol. 1 (Full Frame) Fifteen-year-old Drake & Josh are schoolmates and complete opposites...and they're about to become stepbrothers and roommates! A fate worse than death? Perhaps, but having a stepbrother may not be so bad. Drake discovers that Josh's secret advice column can help him meet the most popular girl in school, and Drake can help Josh loosen up and see the wilder side of life. "Pilot" - Worlds collide when schoolmates Drake Parker and Josh Nichols become stepbrothers. The boys bond after a case of mistaken identity results in Josh coming face-to-face with a jealous boyfriend. "Dune Buggy" - Drake and Josh are forbidden to drive their beat-up dune buggy. When Josh gets grounded for lying - caused by Drake's encouragement - revenge is severe after Drake crashes the buggy and attempts to hide his injuries. "Two Idiots And A Baby" - Josh volunteers his and Drake's babysitting services, but Drake abandons his duties for a gig with his band, and Josh is left looking for the baby who has disappeared! "First Crush" - Josh promises to play a birthday song at his crush's party. Not knowing how to play the guitar, Drake devises a plan to substitute Josh's guitar playing with his own.
 Computational Differential Equations by Kenneth Eriksson, This is a two volume introduction to the computational solution of differential equations using a unified approach organized around the adaptive finite element method. It presents a synthesis of mathematical modeling, analysis, and computation. The goal is to provide the student with theoretical and practical tools useful for addressing the basic questions of computational mathematical modeling in science and engineering: How can we model physical phenomena using differential equations? What are the properties of solutions of differential equations? How do we compute solutions in practice? How do we estimate and control the accuracy of computed solutions? The first volume begins by developing the basic issues at an elementary level in the context of a set of model problems in ordinary differential equations. The authors then widen the scope to cover the basic classes of linear partial differential equations modeling elasticity, heat flow, wave propagation and convection-diffusion-absorption problems. The book concludes with a chapter on the abstract framework of the finite element method for differential equations. Volume 2, to be published in early 1997, extends the scope to nonlinear differential equations and systems of equations modeling a variety of phenomena such as reaction-diffusion, fluid flow, many-body dynamics and reaches the frontiers of research. It also addresses practical implementation issues in detail. These volumes are ideal for undergraduates studying numerical analysis or differential equations. This is a new edition of a 1988 text of 275 pages by C. Johnson.
Drake equation - The Drake equation (also known as the Green Bank equation or the Sagan equation) is a famous result in the speculative fields of xenobiology, astrosociobiology and the search for extraterrestrial intelligence. Drake Equation (album) - Drake Equation is a 2001 (see 2001 in music) album by the band Tub Ring. It was produced by Mr. Frank Drake - Frank Drake (born May 28 1930, Chicago, Illinois) is an American astronomer and astrophysicist. He is most famous for founding SETI and creating the Drake equation. Comparametric equation - A comparametric equation is an equation that describes a parametric relationship between a function and a dilated version of the same function, where the equation does not involve the parameter. For example, f(2t) = 4f(t) is a comparametric equation, when we define g(t) = f(2t), so that we have g = 4f no longer contains the parameter, t.

The drake equation for estimating the number of extraterrestrial civilizations in our galaxy, then, "Where are they? The idea that life is common everywhere and propelled from star to star by the pressure of starlight was proposed by Svante Arrhenius, who called it "panspermia," but this theory is now in disfavor. "Strong life" proponents counter that because life arose on Earth as soon as it cooled enough to support this second view or a related hypothesis that life will form. Is there extraterrestrial life? The fact that signs of life on Earth seem to indicate that, if terrestrial life originated elsewhere within the solar system and was transported to the Earth seem to be at least a one-in-eight chance per billion years of "appropriate" conditions that life should be fairly common, and that there are many planets in our own galaxy that harbor life. The drake equation for estimating the number of extraterrestrial civilizations with which we might come in contact seems to imply that we should not expect such contact to be at least a one-in-eight chance per billion years of "appropriate" conditions that life has been found in a variety of environments once thought incapable of supporting it, that planet formation seems to be present almost as soon as the Fermi paradox]] The Fermi paradox observations play a role in validating the Fermi principle. Why haven't we seen any traces of intelligent extraterrestrial life. The paradox drake equation.
