All experiments
The complete list of experiments on this site, what subject each one covers, and how it works under the hood. Every row links to the live page.
Six experiments are online and all six are finished. Three subjects are represented, two each, and each demo was built to answer one question you can actually poke at rather than read about. Chemistry gets two: the periodic table as a map of trends, and radioactive decay as a probability game. Biology gets two: the parts of a cell, and natural selection running in front of you. Physics gets two: the delta-v budget that decides whether a rocket reaches orbit, and what relativity does to the clocks on an interstellar trip. The table below is the fastest way to see the whole lineup at once, including the mechanic behind each demo, so you can pick the one that matches what you feel like doing right now.
| # | Experiment | What you do | How it works |
|---|---|---|---|
| Chemistry | |||
| 01 | Periodic Trends | Color all 118 elements by radius, electronegativity, or ionization energy. | Buttons swap which measured value drives the color scale. |
| 04 | Nuclide Decay | Pick any of 30 nuclides and watch 400 atoms decay toward stability. | Pick any of 30 nuclides on the chart, then every atom walks its own decay chain. |
| Biology | |||
| 02 | Cell Explorer | Compare animal, plant, and bacterial cells. | Tabs switch the diagram, and clicking an organelle shows its one job. |
| 05 | Peppered Moths | Hunt moths and shift a population over twelve generations. | The survivors' color mix seeds the next generation, and a bar chart tracks the dark-moth share. |
| Physics | |||
| 03 | Rocket Lab: Δv | Build a rocket and check whether it reaches orbit. | Engine buttons and mass sliders feed the Tsiolkovsky equation, and the trajectory redraws from ballistic arc to escape path. |
| 06 | Starship Clock | Pick a star, design a ship, and compare the two clocks. | The Lorentz factor handles constant velocity, and the relativistic rocket handles constant acceleration. |
Each experiment is a single HTML page with its own script. The stage header on every demo names its main script, so the source is easy to find and each demo stays small enough to read in one sitting.
How to read this table
Each group heading tells you which accent color those pages wear. Chemistry pages are teal, biology pages are green, and physics pages are violet, and that color runs through the demo stage border and the controls on that page. The last column is the honest part: it says what the code actually does, including where a simulation is simplified. None of these demos is a research tool. They are built to make one idea visible and to say plainly where the model stops.
