First, gratuitous beauty, though perhaps beauty is never gratituitous.
From Larry came two short videos for which I thank him.
The first demonstrates the difference in water circulation north and south of the Equator. I know this first hand, though even after all these years I sometimes have to consider for a moment. In the northern hemisphere water circulates around a drain clockwise. In the southern, counter clockwise. So do the major oceanic winds. Think northeast trades and southeast trades and it is easy to complete the circles. Winds around lows circulate in the opposite direction.
However I have never seen this so clearly demonstrated and am startled by how definite the demarkation is and what happens exactly on the Equator.
The second video displays suburb boat handling and why lighthouses should be automated. Most now are. I am not sure why this one isn’t. A serious commute.
