About

Double Pendulum Simulation

Explore the chaotic and dynamic behavior of a double pendulum. This app uses the Runge-Kutta method to solve differential equations, allowing you to influence the pendulum's motion by tilting your device.

Highlights
  • Double pendulum simulation
  • Runge-Kutta method solver
  • Chaotic dynamics exploration
  • Device tilt interaction

In mathematics, in the area of dynamical systems, a double pendulum is a pendulum with another pendulum attached to its end, and is a simple physical system that exhibits rich dynamic behavior. The motion of a double pendulum is governed by a set of coupled ordinary differential equations. For certain energies its motion is chaotic. This application solves these differential equations using the Runge-Kutta method for the time stepping. You can influence the movement of the pendulum by holding your device in different positions.

Most failures of understanding are failures of scale. FractalView is a thinking environment designed to help you move fluidly between detail and meaning—without losing context. Human beings evolved for linear thinking. We now live in a logarithmic world. FractalView makes jumping orders of magnitude feel natural. The Core Idea Scale isn’t just visual zoom—it’s resolution. Different levels of scale demand different kinds of thinking. FractalView is built on a fractal model: the same structure repeats at every level. Whether you’re examining a sentence, a system, or a civilization, the underlying patterns often rhyme. You’re not clicking through folders—you’re traveling through the idea itself. Three Modes of Thought FractalView offers three distinct modes, each tuned to a different kind of work. Scholar — What is true? Designed for research, writing, and interpretation. Scholar mode helps you examine ideas across levels of abstraction: evidence, claims, arguments, and significance. It supports careful thinking about sources, patterns, and meaning—without losing sight of why the work matters. Builder — What must not break? Designed for systems, teams, and care. Builder mode focuses on continuity, failure points, and trust. It helps you reason across moments, processes, and structures—so local fixes don’t quietly degrade the larger system you’re responsible for sustaining. Founder — What creates value? Designed for strategy, leverage, and direction. Founder mode helps you connect daily decisions to long-term outcomes. It surfaces how small changes compound, where real leverage lives, and how micro-friction often mirrors macro-failure. What FractalView Enables Semantic Zoom As you move between scales, the content itself changes—facts become patterns, patterns become stakes. Fractal Structure Each idea remains coherent at every level. Micro-problems often share the same shape as macro-problems. Split-Scale Awareness Work in the details while keeping the larger frame visible. Avoid collapsing into noise—or drifting into abstraction. Scalar Thinking Tools Guided prompts help you reason downward (root causes) and upward (implications), training a skill used instinctively by great thinkers across disciplines. Who It’s For FractalView is for people who think for a living: Writers and scholars holding thesis and sentence at once Builders responsible for systems, communities, or teams Founders balancing execution with long-term vision Students stuck between “too big” and “too small” Anyone trying to understand how today’s actions connect to larger meaning The Deeper Claim FractalView isn’t a productivity app. It’s a scale literacy tool. Over time, it trains a cognitive motion: the ability to move up and down levels of abstraction without losing clarity, care, or purpose. Meaning lives at every scale—from the footnote to the thesis, from the moment to the infinite.
