The symmetry principle is described in this paper. The full details are given in the book: J. Rosen, Symmetry in Science: An Introduction to the General Theory (Springer-Verlag, New York, 1995).

This article demonstrates that science is founded on symmetry and that Nature must have symmetry at its foundation. Full details are given in the book: Rosen, J. Symmetry Rules: How Science and Nature Are Founded on Symmetry; Springer-Verlag: Berlin, Germany, 2008.

Working with digital video technologies, particularly advanced video tools with editing capabilities, offers new prospects for meaningful learning through design. However, it is also possible that the additional complexity of such tools does not advance learning. We compared in an experiment the design processes and learning outcomes of 24 collaborating participant pairs (dyads) using 2 contrasting types of video tools for history learning. The advanced video tool WebDIVER supported segmenting, editing, and annotating capabilities. In the contrasting condition, students used a simple video playback tool with a word processor to perform the same design task. Results indicated that the advanced video editing tool was more effective in relation to (a) fostering student understanding of the topic and acquisition of cognitive skills, (b) the quality of student design products, and (c) the efficiency of dyad interactions. The implication of our experimental findings for constructivist design-based learning is that mediating functions of video tools may be used as cognitive and social supports, for example when students learn by solving design tasks in school.

In order to help make the ideas of classical microirreversibility and chaos more accessible to interested nonspecialists, a narrative style discussion is presented. It is shown, based on an operational understanding of time reversal symmetry, that irreversibility, i.e., time reversal asymmetry, is a property of the microevolution of classical dynamical systems in general. Yet approximate microreversibility may be exhibited for sufficiently short durations. The cause underlying universal microirreversibility is the generally divergent evolution of classical dynamical systems and the consequent sensitivity of the evolution to initial conditions. Divergent evolution is responsible also for the indeterministic, i.e., chaotic, behavior of those systems.

The fallacy of \"the flow of time\" and \"the arrow of time\" is pointed out, and a better notion of time, in terms of becoming, is offered.
