She engages in the administrative, cultural, political dimension of personal and collective identities. By triggering intersubjective alliances she confronts the 'self & other' to the commons, co-authorship and the redistribution into the public domain.

DEEP TRASH FROM OUTER SPACE - Goldsmith, October 2016

Today we will inhabit and enable diverse/other morphologies, bodies, physiologies and experiment with how technology can hack into our pyscholgical, neurological, ...experience how it, he, she, we,  can immerse us, temporarly into different positionalities, in a very queer desire to break with the dominant, normative and often violent narratives and technologies, of representation and experiences, that we exist within, that pre-exist us and that are always already producing our subjectivity, permeating our lives up to the most personal and subtle levels.

This desire is not just escapism: when we immerse ourselves in realties in which we are not disempowered, and where experiences are centered. Espcially when we do it seriously and collectively. If we can take ourselves out these heavy oppressive and often violent environments where we always are already other, based on cultural, scientific and theorical narratives which preexist us. 

Momentum created between lived and fantasy positionalities is where we can begin to decolonize our imagination, reimagine and represent our own subjectivity constituted within, a constant becoming , non observed states, into the dynamic of particle and wave.

<picture of lightning>
* K Barad 

The path that lightning takes is not only 
not predictable, it does not make its way in
some continuous fashion between sky and
ground. There is, as it were, some kind of
nonlocal communication effected between
the two. By some mechanism scientists
have yet to fully explain, a storm cloud be-
comes extremely electrically polarized –
electrons are stripped from the atoms they
were once attached to and gather at the
lower part of the cloud closest to the earth.
In response, the earth’s surface becomes
polarized with these earth-bound electrons
burrowing into the earth. A strong electric
field between earth and cloud results, and
all that remains to be accomplished now is
a conductive path joining the two. The first
inklings of a path have a modest beginning
offering no indication of its explosive end.
“It begins as a small spark inside the cloud
five miles up. A spurt of electrons rushes
outwards, travels a hundred meters then
stops and pools for a few millionths of a
second. Then the stream lurches off in a
different direction, pools again, and again.
Often the stream branches and splits. This
is not a lightning bolt yet” (Discovery
Channel 2007). 37 These barely luminous
first gestures are called “step leaders”. But
the buildup of negative charges (electrons)
in the lower portion of the cloud does not
resolve itself by a direct channel of elec-
trons making their way to the earth in this
fashion. Instead, the ground responds next
with an upwards signal of its own. “When
that step leader is within ten or a hundred
meters of the ground, the ground is now
aware of there being a big surplus” of
charge, and “certain objects on the earth
respond by launching little streamers up to-
ward the step leader, weakly luminous plas-
ma filaments, which are trying to connect
with what’s coming down”. It is as though
objects on the ground are being hailed by
the cloud’s interpellative address. When
one of the upward responses is met by the
downward address, the electrical circuit is
closed and a powerful discharge is effected
in the form of a lightning strike. But even
after the path has been carved, as it were,
the discharge does not proceed in a conti-
nuous fashion: “The part of the channel
nearest the ground will drain first, then suc-
cessively higher parts, and finally the charge
from the cloud itself. So the visible light-
ning bolt moves up from ground to cloud
as the massive electric currents flow down”

An Newtonian orbit  is possible here in museum Abteiberg:
2009 music-videoclip :https://www.youtube.com/watch?v=A0TQ97TCTKY

<picture: earth orbits us>
We orbit, we are on earth, in 365 days we orbit around the sun.

There is gravity and a magnetic field.
But to guide us, I go a little bit confused with orbit on a macro scale and on a nano scale 
and language / sprache / taal - etymologically / orbite - eye :
late 14c., "the eye socket," from Old French orbite or directly from Medieval Latin orbita, transferred use of Latin orbita "wheel track, beaten path, rut, course, orbit" 

An object's momentum and the force of gravity have to be balanced for an orbit to happen. If the forward momentum of one object is too great, it  will speed past the other one and not enter into orbit. If momentum is  too small, the object will be pulled into the other one and crash. Orbital velocity is the speed needed to stay in orbit. At an altitude of  242 kilometers (150 miles), this is about 17,000 miles per hour.  This  is just a little less than full escape velocity. Low-Earth Orbit (LEO) 90 minutes. (photgraphic) Geosynchronous Earth Orbit (GEO), Molnya orbit still / lightening).

The time it takes a satellite to make one full orbit is called its period. When a meteorite enters our atmosphere and becomes a "shooting star," it is no longer in an orbit.

A physical body as a whole is assumed to have such quantitative properties as mass, momentum, electric charge
In mysticism, such as theosophy, the physical body is understood as the last of several progressively denser "vehicles of consciousness"
 body is contrasted with the self, mind, spirit, soul, or astral projection.

An antenna converts AC power to an electromagnetic field consisting of radio waves, and vice versa. When transmitting, the antenna leaves the alternating current as an electromagnetic field. This field is referred to as the radio signal. the transmit power of the antenna is important
An antenna emits electromagnetic waves with a certain power: the transmission power. This power is expressed in watts (W). To send the installation takes power of the grid, and this provides power to the antenna. > ERP (Effective Radiated Power); effective radiated power.

propagation: longitudal or transverse 
Transverse wave is one of the two basic forms of waves. To understand a  transverse wave, an essential understanding of wave mechanics is  required. A wave is a method of transferring energy. As the wave  propagates through the space, energy it carries is also propagated. This  energy causes the particles on the way, to oscillate. In other words,  the energy is propagated through the oscillation of particles.  
In transverse propagation the particle displacement is perpendicular to the direction of wave propagation. In longitudal propagation, particle displacement is parallel to the direction of wave propagation and oscillate about a fixed equilibrium point in space.  Since the oscillations are parallel to the movement, a pressure  difference is caused.  (e.g soud > in the ear)

Bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities.
Magnetoreception  is a sense which allows an organism to detect a magnetic field to  perceive direction, altitude or location. This sensory modality is used  by a range of animals for orientation and navigation,[1]  and as a  method for animals to develop regional maps. For the purpose  of  navigation, magnetoreception deals with the detection of the Earth's  magnetic field. Humans are not thought to have a magnetic sense, but  there is a protein (a cryptochrome) in the eye which could serve this  function.

Professor R.Wever from the Max Planck Institute for Behavioural  Physiology in Erling-Andechs, built an underground bunker which completely screened out magnetic fields. Student volunteers lived there for four weeks in this hermetically sealed environment. Professor Wever noted that the student's circadian rhythms diverged and that they suffered emotional distress and migraine headaches. As they were young  and healthy, no serious health conditions arose, which would not have  been the case with older people or people with a compromised immune  system. After only a brief exposure to 7.8 Hz (the very frequency which  had been screened out), the volunteers health stabilized again.
