# Brownian Motion 1.0 APK

1.0 / April 19, 2014
(3.9/5) (21)

## Description

Simulate Brownian motion with particles that interact only byelastic collision. Change the simulation parameters in thepreference settings. Use the gravity sensor for an additionalforce. Select between 5 different predefined parameter settingswhere the yellow particle has X times the mass of the otherparticles.

VecFieldLIC 1.0 APK
VecFieldLIC visualizes 2D autonomous dynamical systems by means ofthe Line Integral Convolution (LIC) technique introduced by Cabraland Leedom in 1993.A 2D autonomous dynamical system is defined bytwo coupled first-order differential equations dx/dt = P(x,y) anddy/dt = Q(x,y) with P and Q being two arbitrary C^1-differentiablefunctions of x and y.These two functions can consist of allmathematical functions available from the OpenGL ES ShadingLanguage.Note that you have to insert numbers as floats, e.g. "2"should read "2.0".

DoublePendulum 1.1 APK
Simulate a mathematical double pendulum on your Android device.Change all the simulation parameters in the preference settings.Use the gravity sensor for realistic simulation depending on howyou hold your device in your hand. Switch between Cartesian andpolar grid background for better orientation. Take a snapshot ofyour most curious pendulum simulation.
Black Hole (light) 1.1 APK
A black hole is the most weird object in the universe. An objectthat passes behind it appears strongly distorted because of theblack hole's influence on light propagation. Turn your smart phoneor tablet into a general relativistic simulator and move the blackhole around.The visualization is based on Einstein's general theoryof relativity for a Schwarzschild black hole. The object isrepresented by an image that is put on a canvas behind the blackhole. The distance between the canvas and the black hole, as wellas the distance between the black hole and the observer, can bemodified. Of course, the black hole mass can also be changed. Forthe screenshots, NASA's "Blue Marble" photograph of Apollo 17 andthe Milky Way panorama by ESO/S.Brunier were taken.Your smart phoneor tablet has to support 32 bit floating point operations on thegraphics card, otherwise, there will be artifacts or nothing willbe shown.Please note that you can use only images that fit into theGPU texture memory of your device.
AccretionDisk 1.0 APK
Simulate a thin accretion disk around a black hole on your Androiddevice. The visualizations are based on Einstein's general theoryof relativity for a Schwarzschild black hole. The apparentdistortion of the disk is due to light rays that follow the curvedspacetime. Because of the heavy use of the GPU the visualizationmight be slow or even show nothing on older devices. That might bedue to the insufficient precision of the graphics chip.In contrastto the 'Gargantua' black hole from the movie 'Interstellar', theblack hole has no proper spin, but it takes the lensing effect andthe Doppler shift into account which let the left part of the diskappear much brighter than the rest.
SRT-ImageDistortion 1.0 APK
Have you ever wondered about how the world around you would looklike if you could travel with nearly the speed of light? Turn yoursmart phone or tablet into a special relativistic simulator andwatch buildings around you apparently deform the faster you move.The physics behind this visualization is the special relativisticaberration effect. The only thing you need is an image that coversthe full sphere (4pi sterad) in equirectangular projection. Theinitial image shows a 4x4x4 grid. You as the observer will alwaysbe at the center of the image but you can have differentvelocities. To watch only the aberration effect, load a blank whiteimage and modify the 'Grid strength'.
