Root Locus Plotter
Read full descriptionHide full description
Root Locus Plotter is an educational and engineering tool designed to help you visualize and analyze control systems through the Root Locus method. Whether you’re a student learning control theory or an engineer designing feedback systems, this app makes it easy to understand the dynamic behavior of transfer functions and how poles and zeros affect system stability. - Key Features Root Locus visualization: Instantly plot the root locus of any transfer function. Gain and stability analysis: Inspect how system poles move and identify stable or unstable regions. Step response: Visualize the step response with interactive charts and get the analytic expression for transient and steady-state behavior. Support for complex systems: Works with higher-order transfer functions. Compare before and after compensation: View the root locus and step response for both the original plant and the compensated system side by side. - Educational Use Ideal for students studying control systems, feedback theory, and dynamic response. The app provides a clear and intuitive way to connect mathematical analysis with visual intuition — a great aid for classroom learning, homework, and lab work. - Engineering Use Engineers and researchers can use Root Locus Plotter to quickly test transfer functions, prototype controller gains, and study how poles and zeros interact under varying parameters. - Get Started Simply enter your transfer function in a clean, intuitive interface, and explore how it behaves as system parameters change. Root Locus Plotter helps you make control theory visual, interactive, and understandable.

Resonant Quantum Mechanics is an educational app that introduces quantum states, quaternions, projection, hydrogen, and the periodic table through guided lessons and interactive 3D visuals. The app is designed for learners who want a more geometric and visual way to think about quantum mechanics. Each lesson combines clear written explanations with Unity-powered interactive scenes that help show how quantum states can be understood through rotation, orientation, phase, and higher-dimensional geometry. Topics include: Why geometry matters in quantum mechanics An introduction to quaternions Quaternionic state representation Projection and measurement Hydrogen energy levels Element structure and spectral patterns No login is required. The app is built as a learning experience for students, independent researchers, and anyone curious about quantum geometry.
