ingredients

cardamom foam

50g cardamom pods
30g granulated sugar
500ml semi-skimmed milk

combine the cardamom, sugar and milk in a
small saucepan and stir over heat until the sugar is dissolved. Bring
to the boil, then remove from the heat and leave to infuse for 1 hour.


Strain the milk mixture through a sieve and discard the solids.


To serve, gently re-warm the infused milk and whisk with a hand
blender until it foams. Spoon a little foam onto each mousse cup and
dust with the dried orange powder.

Wherever there is energy, there will be bubbles
wherever there is gravity, bubbles will make foam
Whipped cream, shaving lather, tomato foam, sea scum,… all these materials are complicated composites, so you might think that’s why foam, in practice, is a difficult material to study. But actually, there’s more "simple".
No need even for two different materials, to start studying foam and performing experiments. A mathematical, abstract system of identical particles, in an abstract empty space is allready good anough a model, that can actually be tested on a real existing situation;
No need for fazes, thermodynamics, no need for liquid and gas, or vapor.
Movement energy ( for instance high frequency /high volume  sound) can create bubbles of vacuum in any liquid matter. So a very basic phenomenon to study, is a coarse distribution of particles in space. The particles themselves need not be identified. Suffice the forces that act between them and perhaps one external force field. One rule governing the attractive and repulsive force between any two particles, depending on the distance between them. And a second rule, for a force felt by each particle, depending on its place in space. (think of gravity for instance) These forces will determine the evolution in time of the particle distribution. Then, mathematically the problem is reduced to finding what kind of fields and particle interaction is necessary to produce foam.

Actually: the perfect example is the universe, as studied by astronomers. Mass distribution in the universe, on a very large scale actually has a foam-like structure.
It evolved into this structure, coming from a uniform smooth spread of mass.

So in conclusion: foam may be fragile, but it will always be there.

Waar alles middelpunt geworden is, bestaat geen middelpunt meer.

Verschuiming en virtualisering is een proces waar alles zijn eigen (bewegend?) middelpunt wordt.

De elektrische gelijktijdigheid van de informatiebewegingen resulteert in de vibrerende totaalsfeer van de auditieve ruimte waarvan het middelpunt overal is en de omtrek nergens. (Marshall Mc Luhan)
