Differential Equations: The Exponential Map Perspective - Lecture 1
The first in a series of lectures which will examine differential equations from the perspective of the exponential map. The first lecture starts by considering real exponents, where several key exponent properties are assumed to be true for ALL REAL NUMBERS (this was not made clear in the lecture). From there, we derive several basic exponent properties that we know from basic algebra. We begin to study Taylor series, and will eventually define complex exponents using the exponential function. This will serve as a spring-board towards demonstrating the importance of the exponential function in mathematics, and the ideas will be used later on when we talk about the exponential of a matrix. Differential equations, matrix theory, dynamical systems, exponential map, exponents, complex numbers, Taylor series, taylor polynomials, sequences, series, vector field, equilibrium, linearization, stable manifold, unstable manifold.

PROGRAM: RECENT TRENDS IN ERGODIC THEORY AND DYNAMICAL SYSTEMS DATES: Tuesday 18 Dec, 2012 - Saturday 29 Dec, 2012 VENUE: Department of Mathematics,Faculty of Science, The Maharaja Sayajirao University of Baroda, Vadodara PROGRAM LINK: http://www.icts.res.in/program/ETDS2012 DESCRIPTION: "Dynamical Systems" is an exciting and very active field in mathematics that involves tools and techniques from many areas. A dynamical system can be obtained by iterating a function or letting evolve in time the solution of an equation. Even if the rule of evolution is deterministic, the long term behavior of the system is often chaotic. Different branches of "Dynamical Systems", in particular "Ergodic Theory", provide tools to quantify this chaotic behavior of the system and to predict it in an average. This program has been planned in two parts: 7 day Workshop (Dec 18-24, 2012) followed by 4 day Discussion Meeting (Dec 26-29, 2012). The aim is to bring together on one platform experts from around the world who are actively working in various sub-disciplines of Dynamical Systems. An important aspect of the program will be an emphasis on making it accessible to younger participants. The workshop will begin with lectures on basic Ergodic Theory followed by lectures on Topological Dynamics, Differentiable Dynamics and Symbolic Dynamics, including Cellular Automata. It will have a `problem and discussion' session every day. Many researchers from across the globe will be discussing their celebrated works in Ergodic Theory, Dynamical Systems and related areas during the four days of the Discussion Meeting. We will encourage young participants to present a short communication on their work in the presence of the eminent experts during the program.- published: 08 Oct 2013

Interactive Exploration of a Dynamical System
A user interface for exploring systems of differential equations. Every variable is shown as a plot; every parameter has a knob that can be adjusted in realtime. This ubiquitous visualization and in-context-manipulation helps the user develop a sense for how the parameters of the system influence its behavior.

Attractor Fun in Houdini
A continuous dynamical system can be described by a set of differential equations. The state of the system can then be represented as a set of points in the phase space. As we solve the system from an initial position we see more and more points (states) appear and we can observe how it evolves through time. Some of these systems have almost perfect periodic behavior but keep varying chaotically around certain areas. These are strange attractors.
We solve for the solutions of these equations with an ODE solver that was implemented in Python. It solves a set of 100K 3-ode in a second or so (depends on the equations of course).
A discrete dynamical system works in a similar way but has discrete states and can be computed much more easily by iterating a function a sufficient amount of times. I used VEX for this method as well as the nonlinear transformation (which is just for aesthetic fun, it has no special meaning in this context of attractors).
I found that the main difficulty with these attractors is to get a good sampling of the range you work on because often solutions converge or become denser at some points so that if you calculate a million steps most of these will appear in tiny areas bunched up together. You can somewhat get around this by creating a line and resampling that with equally spaced divisions. Other times I tried to get a shaped random distribution of the domain (more guess than anything else).

cmiVFX Releases New NAIAD Simulating Liquids Volume 1 Training Video
Wellington, NZ (November 30nd, 2011) – cmiVFX releases the "first ever" Naiad training video, continuing the long streak of "first ever" inventions, processes and techniques the company is well known for. This is the first volume of a series and focuses on entry level to middle level concepts and theory behind this powerful, yet nearly undiscovered software package. This training will teach the viewer the basic principles behind a F.L.I.P. Solver and level sets theory utilizing practical examples.
This training covers all the basic concepts of the Naiad graph system and analyzes in depth the process of generating a hero boat wake.
This volume 1 video introduces the viewer to Navier-Stokes equations and level set methodology of working, as they are useful concepts and they describe the physics of many things of academic and economic interest. The viewer will learn the common behaviors of digital liquids and how to setup graphs with forces and dynamic properties such as “viscosity”, “surface tension”, “friction” and how they interact with the pressure solver. As a bonus this volume comes with a library of all the example scenes and Naiad package is directly downloadable in learning edition from the Exotic Matter website.
Here at cmiVFX we maintain a current training library for the latest versions of popular software titles. When it comes to high end CG and VFX training, there is only once choice... cmiVFX!
Don’t forget about the cmiSubscription plan! Get one today. cmiVFX launched the most affordable subscription plan in Visual FX Training History for only $299 USD, and if you were a subscriber, this New Training Release would already be in your account. This video is also available a-la-cart in our brand new HTML5 player system.

"Solar Equation" (2010) by Rafael Lozano-Hemmer
"Solar Equation," 2010
Aerostat, 5 HD projectors, 7 computers, custom software
14m / 48' balloon
"Solar Equation" is a large-scale public art installation that consists of a faithful simulation of the Sun, 100 million times smaller than the real thing. Commissioned by the Light in Winter Festival in Melbourne, the piece features the world's largest spherical balloon, custom-manufactured for the project, which is tethered over Federation Square and animated using five projectors. The solar animation on the balloon is generated by live mathematical equations that simulate the turbulence, flares and sunspots that can be seen on the surface of the Sun. This produces a constantly changing display that never repeats itself, giving viewers a glimpse of the majestic phenomena that are observable at the solar surface and that only relatively recent advances in astronomy have discovered. The project uses the latest SOHO and SDO solar observatory imaging available from NASA, overlaid with live animations derived from Navier-Stokes, reaction diffusion, perlin, particle systems and fractal flame equations.
Using an iPhone, iPod touch or iPad, people may disturb the animations in real-time and select different fluid dynamic visualizations. You can download the free app from here: http://itunes.apple.com/app/solar-equation/id375165357?mt=8
While pertinent environmental questions of global warming, drought, or UV radiation might arise from the contemplation of this piece, "Solar Equation" intends to likewise evoke romantic environments of ephemerality, mystery and paradox, such as those from Blake or Goethe. Every culture has a unique set of solar mythologies and this project seeks to be a platform for both the expression of traditional symbolism and the emergence of new stories. Just like the installation depends on the world's brightest projectors to exist, conceptually the piece is open for the public to make their own symbolic projection and interpretation. Some might experience the work as a traditional son-et-lumiere spectacle, other as a didactic visualization of natural forces, while others as a call to action to harness the sustainability of solar power. Coincidentally, the sun's generates its own energy by nuclear fusion of hydrogen nuclei into helium, the inert gas that is used to fly the maquette.
