There's a phenomenon described in the science of waves that illustrates what happens when two different waves cross paths and interact. If the troughs of the two waves happen to intersect, the waves will subtract from each other and you'll get a trough twice as deep. If the trough of one wave intersects the crest of the other, the waves will cancel out and you'll get flat water. But if the crests of the two waves intersect, they'll add onto each other, and you'll get a wave that for a moment has a crest twice as high.

Here, the waves are coming in from the northeast and hitting the sea wall at something a little less than a 30° angle, then bouncing back out toward the southeast at the same angle. (Angle of incidence equals angle of reflection.) This means the outgoing reflected wave is meeting the incoming incidental wave, and the crests are stacking onto each other at this point. The arrangement of the various walls directed the incoming waves in such a way that this super crest kept appearing at roughly the same spot. It would have made that a fun place to put a surfboard, though it's likely you'd get tossed into the wall.

CONSTRUCTIVE VIEW OF MODERNITY (2010)

Three used oil barrels (blue, red, grey), steel stand (1.5×1.2×1m).

Although for most of us the physical reality of an oil barrel is not a feature of our day-to-day lives, it has a totemic significance as the standard unit of volume expressing the exploitation and consumption of petroleum, and as an index of macroeconomic supply-and-demand. Constructive View of Modernity uses primary units and geometric abstraction to make a deliberately simplistic equation between the beginning of the widespread exploitation of petroleum and the subsequent fueling of industrialisation, with the rise of modernist art.

GLOBALISING THE INTERNATIONALE (2009–ongoing)

Wooden stage on wheels, (6×3×1m), four loudspeakers, HD video (c. 25 min.).

Oil has been processed in the port of Rotterdam, the Netherlands, since the 1960s and Europe’s highest capacity refinery, owned by Royal Dutch Shell, operates there alongside the facilities of four other companies. The context of this formidable powerhouse, and the fact that Switzerland has a direct link to Rotterdam by importing oil along the Rhine from Basel (close to the artists’ home town of Zürich) led Hemauer | Keller to develop Globalising the Internationale (2009) in the context of a series of public commissions initiated by the Port of Rotterdam Authority. Starting with a counter-movement, the artists arranged for an oil tanker to transport a wooden stage from Basel to Rotterdam and followed its progress along the Rhine. This provided the setting for the project’s culmination on the 7th and 8th November 2009. Two professional choirs gave public performances of the Postpetrolistic Internationale a polyphonic choral anthem written by the artists with Mathias Vetter in 2008. The first choir sang quayside in Rotterdam’s maritime heart near the Havenmuseum (Harbor Museum) and the second on the Maasvlakte (port land constructed in the North Sea) with E.ON’s coal-fired power station as a backdrop. Inspired by rousing socialist songs, the artists’ lyrics question and provoke our willingness to face future energy challenges in the light of resource exhaustion and societal excess. “Happiness is wastefulness” incites the anthem’s caustic refrain, echoing the sentiments of the artists’ Postpetrolism Manifesto.

The Postpetrolistic Internationale was performed by a choir at the opening of the United Alternative Energies and in the exhibition Hemauer | Keller present a video document of the stage’s Rhine journey and the Rotterdam and Aarhus choral events, alongside the stage itself with music scores and the invitation for visitors to perform the aspirational anthem of hope-in-action themselves. The score is also reproduced in this publication in the ‘choral octavo’ centre pages.

"Constructive Destruction"

Waves approach the shore from different angles, and therefore have differing path lengths. This causes waves to interact both constructively and destructively at different points in accordance with the superposition principle. This principle states that two waves traveling through the same medium at the same time pass through each other without being disturbed. The net amplitude of interacting waves is simply the summation of the amplitudes of each individual wave at any given point in their interference. Constructive interference causes an increase in wave height. This type of interference occurs when waves overlap at whole number intervals. Destructive interference causes a decrease in wave height, or a trough. This type of interference occurs when waves overlap at half number intervals. In the picture, one can see alternating crests and troughs caused by the interaction of the waves.
