Book XXXIV · Signal / Josephson
Josephson / phoneme–phonon
Track A · BDC/AC equations. Washboard. Shapiro. Voice is not a superconductor.
Physics
Josephson relation I = Ic sin φ. AC/DC effects, washboard potential, Shapiro steps. SQUID / MEG sense phase. YBCO flux pinning is a lattice analogue.
Fence
The I-see-sin pun is wordplay. Voice is not a superconductor. No claim that speech creates a Josephson junction in tissue.
