A Visual History of Human Knowledge | Manuel Lima | TED Talks

New Section

In this section, the speaker introduces the concept of organizing and visualizing information and discusses the shift from a hierarchical tree structure to a network metaphor.

The Great Chain of Being

• The speaker mentions the belief in a natural ranking order known as the great chain of being or "Scala naturae" in Latin.

• This hierarchical structure starts with God at the top, followed by angels, noblemen, common people, animals, etc.

• It was based on Aristotle's ontology and categorized all things known to man into opposing categories.

The Porphyrian Tree

• The concept of the great chain of being evolved into the Porphyrian tree, which became an important communication tool for mapping various systems of knowledge.

• Trees were used to map morality (tree of virtues and vices), consanguinity (blood ties between people), genealogy (family trees), systems of law, and species classification.

Limitations of Tree Diagrams

• While trees were powerful metaphors for conveying information and representing order and balance, they are insufficient for understanding complex challenges.

• A new metaphor is emerging - that of networks - which provides a new lens to understand interconnected systems.

Shift to Network Metaphor

• The network metaphor is replacing trees in visualizing various systems of knowledge.

• This shift can be observed in fields like neuroscience, where the brain is seen as a complex network rather than a modular organ.

• Human knowledge itself is shown to be intricate and interdependent through maps created from Wikipedia articles.

Changing Paradigms in Social Structures

• Traditional organizational charts are being challenged by decentralized structures facilitated by the internet.

• Online social collaboration among programmers demonstrates how networks replace rigid hierarchies.

• Understanding terrorism is also affected by the decentralized nature of independent cells.

New Section

This section discusses the concept of networks and how they are represented in different fields such as organizations, species classification, and ecosystems.

Networks in Organizations, Species Classification, and Ecosystems

• In organizations, networks can be segmented into different years, with influential individuals being connected year after year. This network structure helps to understand the organization's past and future plans.

• The shift from trees to networks is observed in species classification as well. The traditional "Tree of Life" diagram has been replaced by a dense network of bacteria that connects previously separated species. This new representation is called the "Web of Life."

• Ecosystems are no longer simplified predator-versus-prey diagrams but rather complex networks of interactions between numerous species. A diagram mapping the interactions between 100 species related to codfish off the coast of Newfoundland exemplifies this complexity.

New Section

This section explores how networks have become a visual taxonomy and a growing language syntax.

Networks as Visual Taxonomy

• Networks have adopted various shapes and forms, becoming a visual taxonomy with immense diversity. Fifteen typologies showcasing this visual diversity are presented.

• Radial convergence is one popular visualization model used for diverse topics such as gene networks, IP addresses, and Facebook friends. Despite their differences, these topics share the same metaphorical representation through network visualization.

New Section

Networks extend beyond scientific fields and influence traditional art forms like painting and sculpture.

Influence on Art

• Mapping complex systems using network visualization has influenced traditional art fields like painting and sculpture. Artists incorporate network representations into their work, creating a new art movement called "networkism."

• Examples of networkism in art include computer-generated maps of social networks and traditional paintings influenced by network visualization. Artists like Sharon Molloy and Emma McNally are prominent figures in this movement.

New Section

Networkism is not limited to two-dimensional art forms but also extends to immersive installations.

Immersive Installations

• Networkism expands into three-dimensional installations, such as Tomás Saraceno's elastic rope structures that create shifting networks when interacted with. These installations embody the organic nature of real networks.

• Japanese artist Chiharu Shiota creates dense webs of elastic ropes and black wool in room-filling installations, blurring the boundaries between objects, people, and networks.

New Section

Networks represent decentralization, interconnectedness, and interdependence, offering new ways of thinking.

The Significance of Networks

• Networks embody notions of decentralization, interconnectedness, and interdependence. This new way of thinking is crucial for solving complex problems like decoding the human brain or understanding the vast universe.

New Section The Millennium Simulation and the Comparison of Brain and Universe

In this section, the speaker discusses the Millennium Simulation, which is a large-scale simulation of cosmic structure growth. They also highlight the intriguing comparison between the brain and the universe.

The Millennium Simulation

• The Millennium Simulation is introduced as the largest and most realistic simulation of cosmic structure growth.

• It was able to recreate the history of 20 million galaxies using approximately 25 terabytes of output.

Comparison between Brain and Universe

• The speaker finds it fascinating to compare the smallest scale of knowledge, represented by the brain, with the largest scale of knowledge, represented by the universe itself.

• This comparison is described as striking and thought-provoking.
