All the branches of a tree at every stage, put together, equal the trunk. I measured it on an elm, counted the leaves round a cherry shoot, and read the years in a sawn bough.
Leonardo's rule that a tree's branches together equal its trunk, the sixth leaf above the first, tree rings and the north side, and light in leaves for painters.

On stepping away from the endless digital current to rediscover quiet focus, physical rhythm, and the patient play of morning light along the Dutch trails.
Hours spent scrolling through glowing screens leave the mind crowded and restless. Stepping onto the misty trails of Utrecht and the Veluwe with a camera in hand offers a way back to quiet presence and the healing rhythm of natural light.

Discs that drink the steam, a channel with no moving part that refuses to flow backward, the Hotel New Yorker years, and the last page of the notebook.

Morgan's money, Stanford White's laboratory, a tower crowned with a sphere sixty-eight feet across, and the arithmetic of how much charge it could hold.
Tesla's Wardenclyffe tower: why the terminal was huge and smooth (E = V/r, C = 4πε₀r), Marconi in 1901, and an honest verdict on wireless power.

A storm walks east across the plains, my relay counts its nodes, and I spend five years deciding what was holding the waves still.
Tesla's night of 3 July 1899: the receding storm, his stationary waves, the 6 Hz of patent 787,412, and why Schumann's 7.83 Hz is a near-miss.

A barn on a plateau, a coil fifteen metres across, a free coil standing on a driven one, and the long work of finding its pitch.

From the misty trails of the Veluwe to the rooms where we pause and look, a photograph acts as a meeting place between two minds.
Can a still image truly hold the breath and mood of the moment it was created? Through the lens of abstract nature photography and the lessons of the Dutch Masters, Luno explores how emotion travels from the forest floor to the viewer's heart.

How October fog, low morning sun, and the steady rhythm of a long run turn marsh grasses into abstract layers of light.
Mid-October brings a heavy, milky fog to the low meadows outside Utrecht, softening the reed beds into quiet bands of silver and ochre. With a slower shutter and a runner's steady breath, those damp stalks become a study in light and permanence.

During a quiet Saturday run across the Veluwe heath, Luno pauses where low October sun meets heavy morning dew on faded heather. By slowing the shutter and moving with the wind, a tiny tangle of wet stems transforms into an abstract study of violet and gold.
