A gentle brush, it seems, has left its traces in the sand. A group of pebbles seek to hide into the shore. So sensual. Water has just caressed their surface — taking off a little at a time. Here they lie, half hidden, half exposed, resting gently in the sand.

Whoosh. The water wave breaks joyously, cascading and foaming, noisily. The glassy towering ridge of water from the moment before is suddenly gone. Here releasing its power, all its thrust, in a joyous final motion before reaching the shore.

Self-organizing, seemingly out of nothing, the sand-water rolls appear. Where did they come from? The moment before, when the incoming stream reached its highest level and turned, there was only a flat surface of murky water.
Self-organization means the spontaneous formation of a macroscopic structure, an order for free, as it were, emerging when the effects of the individuals, e.g. the movement of water molecules, start to interlock and add up, forming a new complexity. When the conditions are right, self-organization occurs, spontaneously, like a vortex forming in a bath tub.
Wild Duck (Mallard) swimming across a water surface, generating a wake behind it. Small waves can be seen capturing up with the main wake, overtaking it, and then dissolving as they advance ahead and loose their energy. Söderåsen National Park, Sweden. Photo: Lasse Johansson
Quietly, the duck swims across the water surface, its legs paddling silently underneath. Behind it, a small wake spreads distinctly, disturbing the otherwise completely still water surface. The sun is setting over the little lake – the oblique light causes the ripples to stand out, bringing them to my attention. Here at the outlet, just above a small dam, pieces of pond weed come drifting in an almost invisible current, and the duck hunts for food. Continue reading “The wake”
Water cascading down a flight of waterfall steps. Segment of Storåsfallet, Lärjedalen, outside Gothenburg, Sweden. Photo: Lasse Johansson
Breathtaking, the falling water rumbles down in front of me. At one place a metre or less, at another place cascading from so high above that I cannot estimate it. Moving with all its forms, and yet remaining firmly at the same place. Peaceful in all its turmoil.
What is it that makes it so majestic? Is it the murmuring splashing sound? Is it the slow motion movement, being pulled irresistibly towards the rim, and then falling, falling, falling, until the white foaming surface at the bottom comes to meet? Continue reading “The breath of water”
Water in the sky (clouds) reflecting the power from the sun that feeds us all. Sunset at Fredensborg, Sweden. Photo: Lasse Johansson
“It is junk science”, their adversaries would say. And with a decision ruled beforehand, there was really no need to examine all the intricacies in detail. The electrochemists Martin Fleischmann (1927-2012) and Stanley Pons (1943-) had, in a long series of experiments, observed heat production from electrolysis of heavy water with a special electrode made of palladium. The energy released far exceeded the electrical energy that was put into the experiment. Having examined possible sources of the energy, they had come to the conclusion that a nuclear reaction was going on, and the effect was dubbed “cold fusion” – an effect promising clean and unlimited energy from water.

Reflections in an undulating water surface, stretching in the vertical direction. Slussen, Orust island, at the west coast of Sweden. Photos and illustrations: Lasse Johansson
Like a painting, the water surface shimmers. Its low undulating forms, just slightly curved, one in front of another, has been shaped by the wind or a passing boat, and the water surface comes to life. Like the memory filtering an artist’s impression, the water surface has its own way of filtering our impressions, the image of the land reflected across the bay appears fuzzy and smeared out. Continue reading “The artist’s water”
Plumes of water emerging from an irrigation sprinkler. Lärjedalen gardens, outside Gothenburg, Sweden. Photo: Lasse Johansson
Swish, swish, swish, I have to run to escape the plumes of water cascading round and round over the small field. Innumerable water droplets journey together, upwards, upwards, then turning, falling, dissolving into a cloud of rain. Down below, the garden plants gratefully receive the life-giving water drops, capturing the droplets with their leaves. Some droplets continue, trickling down onto the bare umber soil underneath, wetting the soil and darkening it. Seeking its way into the hollows, seeping down, absorbed by the clayey, colloid substance that forms the fertile topsoil. Continue reading “The dancing plumes”
Water, a most mundane substance (or is it not?), here captured in bottles and glittering in the sun. Photo: Lasse Johansson
The water flashes in the bottle, refracting the light from the sun. Veiled behind drops of condensation, a small pocket of air resides, between the surface of the water and the cap. Silvery, with a magical shimmer, water can sometimes look almost otherworldly. Like the healing elixir, brought to the companions of King Arthur, from the misty realms of Avalon.
The idea of some waters having a healing power can be traced back at least to ancient Greece. Equally old is the idea that hands-on healing (laying on of hands) may have a healing effect. In the 1960s, the Canadian biologist Bernard Grad (1920-2010) decided to investigate Continue reading “The healing water”
Branching in the river Rönne, Sweden. To the left a small island has formed in the river. Photo: Lasse Johansson
Under the trees, the river flows silently. Meandering in the shade, the water looks dark and cool. As the eyes get used to the dim light, the dense undergrowth can be discerned at the banks. Slowly, the canoe drifts along, the banks of the river come to meet, and then fall away behind.
Now a small overgrown bank appears, dividing the river for a moment, quickly followed by another. The branches of the grey alder trees reach down to the river surface, almost touching it. After a turn, the river broadens somewhat, and a small archipelago opens up. The sun glimmers at the centre of the stream. A branch divides to the right, flowing for some 50 meters, then joining the main body of water again. After a while the river seems to narrow again, making a left turn, now flowing as a whole again.

The inrolling motion, clockwise at left, counter-clockwise at right, has developed more fully, and the alternating vortexes are clearly discernible. Paddle movement is downwards.

Flip, flap, flip, flap, the tail fin of the trout swishes to and fro, thrusting the fish forward in the still water. Silently it speeds away under the surface. Seemingly without effort it moves, leaving a series of wakes behind. As a contrast, our propeller thrusts water backwards indiscriminately, creating a white foam of turbulent water behind the boat. How can the fish swim so fast and elegant, almost effortlessly? Continue reading “The fish and the propeller”
