Welcome to ORBIT ✦
Explore the scale of our universe and the numbers within it.
Explore Scale
Move continuously from microscopic and human scales through Earth, planetary, stellar and cosmic scales.
Big Numbers
Build powers of ten, group zeros, compare named numbers, and continue into recursive notation.
Compare
Place radically different sizes on the same logarithmic ruler and calculate their ratios.
Measure
Move between nano, micro, metric, astronomical, and light-distance units.
Count & Fill
Build intuition for huge quantities with direct, grouped, powers-of-ten, and magnitude-line views.
Learn
Structured mathematics and science courses with deep explanations, worked examples, multiple representations, practice, notes, progress, and instrument tasks.
ORBIT Instruments
Five independent working instruments: continuous scale measurement, N-body gravity, generative geometry, a real sound sequencer, and interactive agent fields.
Favorites
Keep scale anchors, numbers, articles, and exploration checkpoints together.
