【實用教育app】DrakeEQ HD|最夯免費app-綠色工廠好玩App

Tired of that “alone in the Universe” feeling? Based on the famous equation by Dr. Frank Drake, DrakeEQ HD for the iPad provides an elegant 3-D simulation of the Milky Way Galaxy and the number of computed intelligent civilizations that it may contain. Learn about the Drake Equation and easily perform beautiful thought experiments with this one-of-a-kind visual tool. DrakeEQ is both educational and entertaining. This tool, like the equation itself, is designed to stimulate your curiosity in the answer to the questions: Are we alone? Where is everybody?Are we alone?: DrakeEQ HD computes/displays civilization count and draws them to the display.Where is everybody?:DrakeEQ HD approaches the Fermi Paradox by positioning the civilizations in 3D space and computing the average distances between them.50% off pricing for enrollees of the Volume Purchase Program for Education. Perfect for Astronomy students!DrakeEQ HD features:• Version 5.0 has been optimized for iOS 7! Works great on iOS 6 too!• Enter parameter values with keyboard or use pop ups to fine-tune results• Run a configurable passage of time simulation and watch colonies expand and contract• Activate a quasar from the Milky Way's black hole, Sagittarius-A*• Highlight the solar system• Display average distance between civilizations • Change star system colors• Tweet results! • Ideal thought experiment tool! The Drake equation states that:N = the number of civilizations in our galaxy with which communication might be possiblewhere:R* = the average rate of star formation in our galaxyfp = the fraction of those stars that have planetsne = the average number of planets that can potentially support life per star that has planetsfℓ = the fraction of the above that actually go on to develop life at some pointfi = the fraction of the above that actually go on to develop intelligent lifefc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into spaceL = the length of time such civilizations release detectable signals into space.Drake equation.
