(a) Quantum FirstPassage Time (QFPT): Extending the original work of Schroedinger for the Classical FirstPassage Time (CFPT). Also, extending Schroedinger.s work to the quantum 1D lattice; (b) Revisiting Bohrvan Leeuwen theorem: On the absence of classical orbital diamagnetism in thermal equilibrium to the case of a random steady state (cyclic equilibrium). Predicting a possible orbital para/ferromagnetism; (c) The discrete, the continuous, and the .concrete. 1D systems, and the elastic energy transport in a spider dragline silk fibre; (d) Accelerating expanding universe: Expanding in what is the question!
