What is Systems Architecture?
• Systems Architecture is the architecture of complexity, inspired by the science of systems biology, which is the scientific study of complex biological systems
What is Complexity Science?
• Complexity Science is a model of the world that is based on exploring the connections between systems in order to characterise them
What is Different about Complexity Science?
• It replaces the Cartesian view of the biological world that assumes systems are made up of components, which are connected to each other as a secondary phenomenon
What are the Characteristics of Complex Systems?
• Characterized by Albert Laszlo Barabasi who demonstrated that complex systems shared common features
Characteristics of Complex Systems
• Independent of embodying medium
• Connect to and organize around ‘hubs’ of activity
• Scalable
• Robust
• Exhibit ‘redundancy’
• Can interconnect through shared ‘hubs’
How does Complexity Science inform Systems Architecture?
• Systems Architecture embraces interlinking material systems and networks that are organised around hubs of activity
• Systems architecture is robust, independent of scale and the embodying medium
What is the Methodology of Systems Architecture?
• As a methodology systems architecture is cross disciplinary and takes the form of an experiment based in complexity science whose outcomes inhabit the realm of the inspirational and surreal rather than following the goal orientated pursuits of science
Systems Architecture in Practice
• Systems Architecture directly connects the organism to nature and the environment, through its multiple, varied connections beyond the immediate realm, dispensing with traditional dichotomies and
hierarchies such as
landscape and city,
or body and architecture
Systems Architecture in Practice
• Systems Architectures are capable of decision making and can evolve
• Need to understand the principles of self organizing matter to engage in the design of materials capable of complex interactions
Self-Organizing Matter
• Characteristic of living systems
Primitive Streak, Karl Grimes
Universe as information
“Life is a fundamental property of the universe”Christian De Deuve
“Chemistry has this computational nature embeddedIn it, which it inherited from the underlying computationThat’s going on in quantum mechanics in general.”Seth Lloyd
"... the Anthropic Principle says that the seemingly arbitrary and unrelated constants in physics have one strange thing in common, these are precisely the values you need if you want to have a universe capable of producing life.” Patrick Glynn
Biogenesis and Systems Architecture
• Biogenesis is the term given to the transition between inert and vital matter
Artificial Life and Systems Architecture
• The discipline of Artificial Life investigates how this ‘transition’ occurs, if there is indeed a transition, between inanimate and vital matter
Artificial Life and Systems Architecture
• The insights from Artificial Life Sciences are crucial for Systems Architecture as we strive to make a transition from a built environment that is composed of inert materials, to one that is capable of life-like behaviour
What is Life?
• No satisfactory definition of life
Does Life Exist?
• Scientist Andrew Ellington argues that definitions of life do not tell us how to make life from an experimental perspective and that trying to define what life ‘is’ does not actually help research objectives
Life As Energy
• “Living matter evades the decay to equilibrium” Erwin Schrödinger, 1944
Life As Information
• “…the essence of life is information, but information is not synonymous with life. To be alive, a system must not only hold information but process and use it. It is the active use of information, and not the passive storage, that constitutes life.”
Freeman Dyson
Life is a Scalar Concept
• Mark Bedau argues that life is a scalar concept
Embodiment
• Process by which information is manifest
• Complex• Not fully understood
or characterized
In Vivo … In Vitro, Daniel Lee
Origin, Daniel Lee
Creating Living Systems
• "Creating a cell from scratch is probably at least 10 years away, but it is going to happen. We're in for some very interesting, very profound new ways of thinking about what life is, and about where you draw the boundary between life and non-life.“ Mark Bedau
Approaches to Designing Artificial Life
• Top down approach bases design principles on existing systems e.g. biomimetics
• Bottom up synthesises new structures from fundamental components
Working Definition of Life
• A working material definition is needed so that the energy and information implicit in living systems is embodied and also so that scientists know when they have something interesting
• Gives rise to entities recognised as fundamental living technologies
Fundamental Living Technology
• Nanotechnological systems capable of traducing information and coupling energy from the environment to convert resources into building blocks, grow and divide
• Characterized by robustness, autonomy, local intelligence, self-repair, adaptation, and self-replication
Gizmo
• “A small self-contained unit of high performance in relation to its size and cost, whose function is to transform some undifferentiated set of circumstances to a condition nearer to human desires.” Reyner Banham
Biology
• “Biology is the Nanotechnology that works” Tom Knight MIT
Definition of Biology
• The spontaneously occurring terrestrial system of nanotechnology capable of self organization and replication that arose out of fundamental living technologies generated
during the Hadean period• Probably happened
many times
How did Biogenesis Occur?
• Two main theories of Origins of Life exist which are both supported by experimental observation
Experimentation that indulges in the messinessAnd ambiguity of everyday life …Archigram
RNA World
• Information First• RNA World is the theory that chemical
information in a particular molecule like RNA which was able to speed up its own production created the driving force behind organised protein synthesis and metabolism
• Walter Gilbert 1986, Thomas Cech and Sidney Altman won Nobel Prize for RNA experiments
Protocells
• Metabolism First• Protocells offer a matrix and
compartment for more primitive technologies to assimilate and concentrate. RNA may have been taken up into the matrix later
• First described by Oparin 1924
Symbiogenesis
• Many different kinds of fundamental living technologies existed simultaneously and gave rise to biological forms through cooperative strategies and alliances
• Konstantin Mereschkowsky 1926
• Freeman Dyson 1980s
Minimal Life
• These are working definitions of what scientists are trying to achieve in the laboratory to prove their hypothesis about how biotic materials become organized in such a way they exhibit characteristics associated with living systems
Minimal Genome
• Top down approach
• ‘minimal genome’
• Pioneering work by J Craig Venter
• First synthetic genome
• Mycoplasma Laborotorium
• ‘Golem’ sequence created ‘in vivo’ and awaits animation in a host
Minimal Cell
• Bottom up approach
• Definition involves three compartments defined by Rasmussen et al.
• Container
• Metabolism
• Information
• Results anticipated in the next 10 years
Complex Systems Dogma
• Alludes to the presupposition that simple lower-level elements can give rise to higher-level dynamical structures
• Steen Rasmussen highlights the shortcomings of such a dogma, claiming that higher-level dynamical structures can only be obtained through forming more complex lower-level structures
Artificial Life Form, Karl Sims
Systems Architecture vs. Smart Technologies
• Smart materials fall into Steen Rasmussen’s definition of simple lower-level elements as they are reflexive
• Systems Architecture employs complex biological systems and fundamental living technologies that constitute Rasmussen’s notion of complex lower-level structures
Origins of Life and Systems Architecture
• Essentially the Origins of Life Sciences are revealing that seemingly primitive chemical systems are capable of great complexity and synthesis
• In other words. Terrestrial materials are rather special and interesting as many of them are not inert
Origins of Life and Systems Architecture
• The scientific field of Origins of Life and what constitutes it, is hugely significant for architecture.
• Traditionally architecture has been made of out inert matter
Systems Architecture: Spectrum of Fundamental
Living Technologies
• Architecture is considered as being separate to, or outside of the organism and an adornment of the environment, not as part of it
• Architecture has occupied the realm of artifice
Systems Architecture: Spectrum of Fundamental
Living Technologies• With the advent of biotechnologies the
inside and outside of an organism has collapsed
• Systems Architecture can be thought of as part of a continuum of evolving, self organizing systems providing it is made of the ‘right’ kind of materials
Model systems• Systems Biology
(complexity)• Synthetic Biology,
the modification of bio nanotechnology to generate novel biological functions and systems
• Fundamental Living Technologies

Systems Architecture and the Extreme Environment
• Beyond our physiological limits the environment has an extreme impact on biology
Sarah Jane Pell, Hydromedusa
Systems Architecture and the Extreme Environment
• Systems Architecture becomes prosthetic in extreme environments
Systems Architecture and the Extreme Environment
• Complexity has its limits
• Complexity collapses when there is only one hub that out competes all the others, when it becomes ‘simple’
Systems Architecture and the Extreme Environment
• “Even though biological organisms span many orders of magnitude in size, their metabolic rates all lie within a single factor of ten. So there does seem to be some kind of broadly optimal rate of energy consumption in our biosphere. Curious. I wonder if it's related to the rate of arrival of solar energy, and planets around different suns, or in different orbits, would have different optimal metabolic rates.” Larry Yaeger
Systems Architecture Perspectives
• With each new philosophical shift in the way that we perceive our world, comes a fresh opportunity to use the science and associated technologies
in innovative ways
Systems Architecture Perspectives
• In Systems Architecture biology connects with the psyche, communications networks, landscape, environment, population dynamics and information systems in an integrated gestalt of flow, like a giant
super-organism
Systems Architecture Perspectives
• Systems Architecture anticipates the evolution of autonomous and autopoietic* architectures
Autopoiesis*
• The process by which an organization produces itself. An autopoietic organization is an autonomous and self-maintaining unity which contains component-producing processes.
• The components, through their interaction, recursively generate the same network of processes which produced them.
• An autopoietic system is operationally closed and structurally state determined with no apparent inputs and outputs.
• A cell, an organism, and perhaps a corporation are examples of autopoietic systems.
Interdisciplinary Methodology
• Systems Architecture requires inter disciplinary collaboration between biological complexity scientists, fundamental living technologists and architects to explore this new territory
Interdisciplinary Methodology
• Systems Architecture is based in complexity science and takes an experimental approach to architectural practice, resulting in design outcomes
“Cell biology is the new cyberspace and nanotechnology. Once we fully understand the exact nature of how our world makes us and, indeed, how it sometimes kills us, we will be able to make true architectures of ecological connectability.”
