Wang et al. introduce a machine learning-driven system that autonomously optimizes polymer film processing, navigating 933,120 conditions to achieve high conductivity. They show AI can streamline manufacturing of electronic polymers from lab to roll-to-roll scale. www.nature.com/articles/s41...

Quantum physics. Consider a physical system and for some reason only one of its components, say an electron, changes its spin state. Under which circumstances this single change could trigger a phase transition in the whole system? Is that possible? Consider entanglement plays a role.

HISTORY OF PHYSICS The Story of the S-Matrix Shortly after the development of quantum mechanics, Dirac, Heisenberg, Pauli, as well as Jordan, Klein and Wigner had shown that relativistic, non-interacting wave fields could be consistently quantized. 1/
