Long Division Simulation – Remainder
A comprehensive simulation that teaches long division with remainders step by step. Ideal for learners needing clear, guided practice. Also available: a version for float (decimal) quotients.
Long Division Simulation – Float
This simulation teaches long division with decimal (float) quotients through a clear, step-by-step interface. Great for learners who need guided practice. A version for remainder-based division is also available.
Simulation Manual: Virtual Oscilloscope
A complete manual for the phase difference between sound waves simulation, including a short introduction and a user guide.

A complete manual for the phase difference between sound waves simulation, including a short introduction and a user guide.
Phase Difference Between Sound Waves Simulation
Use this interactive simulation to visualize the phase difference between two sound waves on an oscilloscope. Measure the microphone spacing and frequency to calculate the speed of sound in air.
Simulation Manual: Refraction of Light
A complete manual for the refraction of light simulation, including a short introduction and a user guide.
Refraction of Light Simulation
Experiment with the refraction of light as it passes from air into a transparent semi-disk. Choose different materials and apply Snell’s law to determine the index of refraction based on your measurements.
Virtual Oscilloscope is Now Mobile-Friendly!
This time I have updated Virtual Oscilloscope so it is now mobile-friendly. Long-press any button, knob, or slider and it will scale up to become comfortable enough for your touch so you can control it comfortably using your mobile device.
I also optimized the code to perform smoothly on mobile devices.Updates to Free Fall Simulation
I updated the graphical user interface for easier interaction and better fitting in the browser. Also, I made a minor bug fix to the code.
Updates to Virtual Oscilloscope
I updated the graphical user interface for easier interaction and better filling in the browser, and most importantly, I made several bug fixes to the code.
