xFractal vs DrakeEQ

Explore the infinite beauty of fractals with your fingertips. Pinch to zoom, drag to pan, and dive into the endless detail of the Mandelbrot set and its relatives — rendered in real time on your device's GPU. xFractal, first released in 2008, is back — rebuilt from the ground up for today's iPhone and iPad. FEATURES: • Mandelbrot, Julia, Newton and Multibrot fractals • Deep zoom: magnify the Mandelbrot and Julia sets more than a trillion times • Four classic palettes — Hot, Cold, Gray and Chromatic — with smooth coloring • Julia presets (Dendrite, Spiral, Rabbit, Galaxy, San Marco), Multibrot exponents 2–8, three Newton polynomials • Replay: watch your whole exploration animate back as a short movie • Picks up exactly where you left off • Free and open source Deep zoom uses K. I. Martin's perturbation technique.

Are we alone? We created DrakeEQ to provide a visually elegant answer to the extraterrestrial question, using the intellectually elegant Drake Equation. We coupled this fun calculator with beautiful, 3D galaxies in motion! To help us celebrate 15 years since the first release in 2009, DrakeEQ 7.0.0 now features our Galaxene Galaxy Engine! Use this fun simulator to graphically quantify the number of advanced extraterrestrial civilizations in our Milky Way Galaxy. Travel the Universe and explore infinitely variable galaxies! Just pinch anywhere and tap the targeting indicator. Perform thought experiments with this unique visual tool; it’s both educational and entertaining. Learn about the famous Drake Equation through direct manipulation of its 7 parameters with DrakeEQ. The Drake Equation states that: N = the number of civilizations in our galaxy with which communication might be possible where: R* = the average rate of star formation in our galaxy fp = the fraction of those stars that have planets ne = the average number of planets that can potentially support life per star that has planets fℓ = the fraction of the above that actually go on to develop life at some point fi = the fraction of the above that actually go on to develop intelligent life fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space L = the length of time such civilizations release detectable signals into space.
