Helicity vs Chirality koan + Jabberwocky syntax-physics + bilingual symmetry breaking

Trit: 0 (ERGODIC - bridge)

Origin

From Interverse transcript (Dec 12, 2025):

"My cat's name is Alice Through the Looking Glass... The difference between helicity and chirality is one is massless. No, no, that's a question you're supposed to answer. A koan usually has the answer."

The Koan

Q: What is the difference between helicity and chirality?

A: Chirality is Lorentz-invariant (intrinsic handedness). Helicity is frame-dependent (spin projection on momentum). For massless particles, they coincide. For massive particles, helicity can flip under Lorentz boosts, but chirality cannot.

MASSLESS: helicity = chirality (locked)
MASSIVE:  helicity ≠ chirality (can differ by frame)

Enantiomeric Reflection

Alice Through the Looking Glass = reflection on:

• Enantiomers: Mirror-image molecules (same atoms, different handedness)
• Chirality: The property of non-superimposability
• Multiscale phenomenon: From proteins to particle physics

Jabberwocky: Syntax-Physics

"The information you are gleaning is information you are getting from the grammar of the sentence. You don't actually need the words."

'Twas brillig, and the slithy toves
Did gyre and gimble in the wabe

You understand:

• "brillig" = adjective describing time/state
• "slithy" = adjective (slippery + lithe?)
• "toves" = plural noun (creatures)
• "gyre" = verb (to move)

Syntax carries meaning without semantics. This is what DisCoPy and categorical grammar formalize.

Bilingual Symmetry Breaking

Elisa (Spanish) ↔ Alice (English)

The full name: "Alice Through the Looking Glass"
- Handed: two elements of the same work
- Via negativa: infer one from absence of other
- Less is more: "Elisa" implies "Alice" to English speakers

GF(3) Chirality Mapping

function chirality_trit(handedness::Symbol)
    handedness == :left  && return -1  # MINUS
    handedness == :right && return +1  # PLUS
    handedness == :achiral && return 0 # ERGODIC
end

# Conservation: L + R = 0 (mod 3) for enantiomeric pair
# But: L + L + R = 0 (mod 3) also works!

The Play

When introducing the cat:

• To English friends: "Alice"
• To Spanish friends: "Elisa"
• Full name breaks symmetry: "Alice a través del espejo"

Commands

# Test chirality koan
