Clifford algebras unify rotations, reflections & geometry in one elegant framework. Complex numbers (i²=-1), quaternions, and spacetime physics are ALL special cases!

Clifford algebras are a mathematical superpower: they generalize complex numbers, quaternions, and handle rotations in ANY dimension using "rotors."

Key insight: The geometric product uv = u·v + u∧v combines dot and wedge products naturally.

Built a full Python implementation from scratch.

Ever wondered what connects complex numbers, quaternions, and Einstein's spacetime?

Clifford algebras! They're a unified framework where:
- Complex numbers are Cl(0,1) with i²=-1
- Quaternions are Cl(0,2) with i²=j²=k²=-1
- Spacetime physics uses Cl(1,3)

The magic: rotations become R·v·R† using "rotors" - works in ANY dimension!

I implemented the full algebra in Python and visualized 3D rotations. Math is beautiful when you see the connections.

Implemented Clifford algebra Cl(p,q) in Python from scratch.

The geometric product is elegant:
uv = u·v + u∧v

Key properties verified:
- Basis vectors: eᵢ² = ±1 (signature dependent)
- Anticommutation: eᵢeⱼ = -eⱼeᵢ for i≠j
- Bivectors e₁₂² = -1 act like imaginary units

Rotors R = cos(θ/2) - B·sin(θ/2) double-cover SO(n).

Complex numbers = Cl(0,1), Quaternions = Cl(0,2), Spacetime = Cl(1,3).

Title: I implemented Clifford Algebras from scratch in Python - here's why they're fascinating

Body:

Clifford algebras (also called geometric algebras) are one of those mathematical structures that seem abstract until you realize they unify almost everything you know about rotations, complex numbers, and physics.

**What I built:**
A complete Python implementation of Cl(p,q) algebras supporting:
- Arbitrary signatures (Euclidean, Minkowski, etc.)
- Full geometric product with grade extraction
- Rotors for n-dimensional rotations
- Reflections through hyperplanes

**The key insight:**

The geometric product combines the dot and wedge products:

uv = u·v + u∧v

For orthonormal basis vectors, you get the fundamental relation eᵢeⱼ + eⱼeᵢ = 2ηᵢⱼ, meaning distinct basis vectors anticommute (eᵢeⱼ = -eⱼeᵢ).

**Why this matters:**

1. Complex numbers are just Cl(0,1) where one basis vector squares to -1
2. Quaternions are Cl(0,2) - Hamilton's i,j,k fall out naturally
3. 3D rotations use "rotors" R = exp(-Bθ/2) instead of matrices
4. Spacetime physics uses Cl(1,3) for special relativity

**The beautiful part:**

Rotations become: v' = R·v·R†

This formula works in ANY dimension, handles gimbal lock gracefully, and the rotor R = cos(θ/2) - B·sin(θ/2) directly encodes the rotation plane as a bivector B.

I verified quaternion identities (i²=j²=k²=ijk=-1) emerge automatically from the Clifford product rules.

The visualization shows rotation trajectories in 3D and the multiplication table of Cl(3,0).

Has anyone else explored geometric algebra? I'm curious about applications in physics simulations or computer graphics.

Ever heard of Clifford algebras? They're a hidden gem in mathematics that unifies:

- Complex numbers (where i²=-1)
- Quaternions (used in 3D graphics)
- Even Einstein's spacetime!

I built a Python implementation from scratch and discovered how "rotors" elegantly handle rotations in any dimension.

The formula v' = R·v·R† works whether you're rotating in 2D, 3D, or 4D spacetime!

Exploring Mathematical Foundations: Clifford Algebras in Python

I recently completed a computational exploration of Clifford algebras - the mathematical framework that unifies complex numbers, quaternions, and geometric transformations.

Key technical accomplishments:

- Implemented Cl(p,q) algebras for arbitrary metric signatures
- Built geometric product, grade extraction, and rotor operations
- Verified isomorphisms: Cl(0,1) = Complex numbers, Cl(0,2) = Quaternions
- Demonstrated spacetime algebra Cl(1,3) properties

The elegant insight: rotations in any dimension reduce to v' = R·v·R† using rotors R = cos(θ/2) - B·sin(θ/2), where B is the bivector defining the rotation plane.

Applications span computer graphics (rotation interpolation), robotics (kinematics), physics (electromagnetism, relativity), and emerging geometric deep learning approaches.

This project demonstrates proficiency in: Python OOP design, numerical computation, mathematical abstraction, and technical visualization.

Clifford Algebras: Where Math Gets Geometric

This visualization shows vectors being rotated using "rotors" - the Clifford algebra way.

Instead of messy rotation matrices, you get one elegant formula:
v' = R·v·R†

The plots show:
- Rotation trajectories in different planes
- How vectors trace perfect circles
- The multiplication table of an 8D algebra

Mind-blowing fact: Complex numbers, quaternions, and spacetime physics are ALL special cases of Clifford algebras.

Math is art when you can see it.
