Mercury’s backward Sun enters the flight plan
A future split-view simulation will pair the Sun’s strange path across Mercury’s sky with the planet’s elliptical orbit and 3:2 spin–orbit resonance.
Timeline
The newest chapter comes first. Below the flight plan, follow the site back to its first experiments.
UpdatedA future split-view simulation will pair the Sun’s strange path across Mercury’s sky with the planet’s elliptical orbit and 3:2 spin–orbit resonance.
A planar gravity sandbox for placing multiple bodies, setting their mass and velocity, then watching stable systems, near misses, slingshots, and collisions emerge.
A wave laboratory for colliding solitons and measuring how their profiles and phases change through the interaction, with crest tracking as a visual analysis tool.
Explore what periodic changes in an asteroid’s brightness can reveal about its rotation and rough, model-dependent shape, beginning with Atala as the reference case.
Future laboratories will explore particle systems, flow fields, fluid behaviour, and other simulations where large-scale motion emerges from many small interactions.
Genshin Impact
The Genshin archive arrives with saved character builds, weapons, artifacts ranked by crit value, and four-character teams with their latest DPS showdown screenshots.

Science, Tools, Gaming, My games, Timeline and About each get their own home. GeoMorph leads Gaming, Blackboard sits under Tools, and the site’s history and introduction move onto their own pages.
The private D1 ledger gets a public statistics view where filters update placement trends, player comparisons, and legend results together.
A pressure-sensitive teaching surface connects desktop and tablet through a private room, turning an S Pen into live chalk for lessons and diagrams.
An original geography game turns a disk into a country through six smooth reveal stages, with separate north-up and rotated daily challenges.
An ideal elastic-collision workbench counts wall and block impacts to show how Galperin billiards can reveal digits of pi.
A hard-disc collision model tracks a probe while its mass, size, and surroundings change.
A rotating orbital sandbox maps effective-potential contours and local Lagrange-point stability while hundreds of test particles respond to two massive bodies.
Life becomes a multi-faction experiment with custom rules, population histories, territorial placement, and mutual diplomacy spanning allegiance, neutrality, and war.
A drawable grid brings the classic cellular automaton to the site, with controls for its speed, density, and starting pattern.
The flocking workbench exposes separation, alignment, cohesion, and obstacle avoidance so their effect on the group can be watched directly.
The homepage fractal grows into a dedicated explorer with touch gestures, progressive rendering, experimental fixed-point precision, and a short article.
The first commit establishes a personal hub, themed content sections, and an interactive science lab.
