Abstraction: Random matrix universality pattern appears across unrelated complex systems

Key points:

• "Universality" — the same eigenvalue spacing pattern (chaotic yet repulsive-neighbor) appears in uranium nucleus energy levels, Riemann zeta zeros, Cuernavaca bus departure times, sea ice, and Internet models
• Discovered in 1972 by Hugh Montgomery in zeta zeros; confirmed in buses by Krbálek and Šeba (2000)
• Wigner's hypothesis: all sufficiently complex, correlated systems exhibit universality
• Terence Tao and Van Vu proved universality for a broad class of random matrices in recent work (circa 2013)
• Universality in sea ice spectral measurements predicts fluid flow and heat conductivity; absence indicates insulation — used by Ken Golden to model Arctic melt ponds
• The underlying reason for the pattern — and its link to the Riemann zeta function — remains unknown; a deeper mathematical structure may underlie both
