Apparatus and method for wake shaping
A device is temporarily attached to one side of the stern of a boat in order to modify the wake pattern of the boat by effectively making one side of the boat longer than the other side. The delayed wave on the opposite side of the boat from the wake shaping device allows the wave to crest over the natural wave on the side where the device is installed. In one example, the device has a frame with a side surface angled outwardly 12 degrees from the side of the boat, a mounting surface with a platform index notch configured to be positioned over a portion of a boat platform. A wedge shape utilizes water pressure to distribute the load evenly across the fastening side of the device, thereby allowing for a tight fit to the back of the boat.

Coherent electromagnetic waves aid reconciliation
Reconciliation of past events is beneficial for resolution of conflict but not essential to resolve geographic, political and economic conflicts that can cease violence. Past events are immutable in spacetime and interpretation of past events may be different for different observers. These events that differ among observers may lead to very different outcomes associated with the event because the activity of the brain is chaotic. Although humans have an innate desire to reconcile past events, resolution of conflicts should be initially concerned with the present and future. Reconciliation is a long and arduous process. In this invention electromagnetic waves that are coherent with natural waves generated by the brain of those in conflict are broadcast through air or wire into areas of conflict to aid reconciliation. Peace may be more easily obtainable with this invention, but this invention will not in itself solve the problem of reconciliation.
