The Tau Manifesto - Mathematical Philosophy
The Tau Manifesto argues for using τ (tau)
= 2π instead of π as the fundamental circle constant:
Core Arguments for Tau:
Geometric Intuition:
- Full circle: τ radians = 1 full rotation (360°)
- Half circle: τ/2 radians = half rotation (180°)
- Quarter circle: τ/4 radians = quarter rotation (90°)
- Eighth circle: τ/8 radians = eighth rotation (45°)
Mathematical Simplification:
Traditional with π:
- Circle area: A = πr²
- Circle circumference: C = 2πr
- Radians in full circle: 2π
With τ = 2π:
- Circle area: A = (τ/2)r²
- Circle circumference: C = τr
- Radians in full circle: τ
Educational Benefits:
- Students naturally think in terms of full rotations
- Trigonometric identities become more intuitive
- Unit circle relationships are clearer

| import math
# Traditional approach
angle_degrees = 90
angle_radians = angle_degrees * math.pi / 180
# Result: π/2
# With tau
TAU = 2 * math.pi
angle_radians = angle_degrees * TAU / 360
# Result: τ/4 (more intuitive)
# Frequency to angular frequency
frequency = 60 # Hz
omega_traditional = 2 * math.pi * frequency
omega_tau = TAU * frequency # Cleaner
|
Practical Implications:
- Programming languages could adopt tau constants
- Engineering calculations become more intuitive
- Educational materials could be simplified
- Scientific notation could be cleaner
TypeLit - Typing Practice with Literature
TypeLit.io provides typing practice using passages from
classic literature:
Features:
