T-symmetry or time reversal symmetry is the theoretical symmetry of physical laws under the transformation of time reversal, Since the second law of thermodynamics states that entropy increases as time flows toward the future, in general, the macroscopic universe does not show symmetry under time reversal. In other words, time is said to be non-symmetric, or asymmetric, except for special equilibrium states when the second law of thermodynamics predicts the time symmetry to hold. However, quantum noninvasive measurements are predicted to violate time symmetry even in equilibrium, contrary to their classical counterparts, although this has not yet been experimentally confirmed. Time asymmetries generally are caused by one of three categories: 1. * intrinsic to the dynamic physical law (e.g., for the weak force) 2. * due to the initial conditions of the universe (e.g., for the second law of thermodynamics) 3. * due to measurements (e.g., for the noninvasive measurements) (Wikipedia).

http://www.teachastronomy.com/ A lot of fundamental concepts in physics are based on the idea of symmetry. Symmetry is familiar to us in an aesthetic sense. It often means things that have pleasing proportion, or look the same from every direction, or have a harmonious nature about them.

The Predictive Power Of Symmetry
From a bee’s hexagonal honeycomb to the elliptical paths of planets, symmetry has long been recognized as a vital quality of nature. Einstein saw symmetry hidden in the fabric of space and time. The brilliant Emmy Noether proved that symmetry is the mathematical flower of deeply rooted phy

Pre-Calculus - The symmetry of functions
This video covers the symmetry that might be present in the graph of a function. A visual approach is taken so that you can see if the symmetry is over an axis, or if its with respect to the origin. Watch for the special names that we give to certain symmetries like "even" and "odd." Fo
