Clustering

In the hunter gatherer society people were living in closely knit social groups. In network theory we speak of highly clustered groups. When different clusters exist within a large network, …

Network distribution and hubs

In this video Wander Jager discusses the concept of hubs. It is being explained what role hubs play in a network, and why we like to connect with the “popular …

Nodes and links

In this video, Wander Jager shows how nodes and links together construct social networks. He explains that there are many things being transmitted through networks, from viruses to information. A …

Everything is connected

In this video, Wander Jager explains that networks are everywhere, connecting trees, neurons in our brain, or galaxies in space. Networks are all about exchanging materials, or ideas. In this …

Network distributions and hubs

In this video Wander Jager explains that with the rise of agricultural society, cities emerged and the total size of the networks became larger than the original small tribes humans …

Information and the internet

In this video Wander Jager reflects on how information spreads in modern networks where in particular the internet plays a large role, and how this sometimes gives rise to clusters …

Social dynamics

In this video Wander Jager discusses how normative and informative influences both play an important role in the diffusion of new ideas, practices and the spread of new products. It …

Exchange of information

In this video Wander Jager explains that information is spreading differently through social networks than a virus. Moreover, hubs may be followed by many people, but they don’t follow back, …

Clustering and tribes

In this video we explain that despite the abundance of social media, humans still have a tendency to cluster in small groups. You will also be introduced to the small …

Reflection

In this concluding video, Wander explains the value of social computation in understanding network dynamics. Processes such as opinion dynamics, polarisation and innovation diffusion can be better understood by experimenting …

An early social-computational model

James Conway’s The Game of Life was an important step for computational social science. It showed that amazing patterns could grow out of simple rules of interaction between cells. In …

Agriculture, writing, hubs and trade

With the development of agriculture, it became possible to produce food in a more efficient way. As a result, tribes could grow, and specialisation became possible. Over time, larger societies …

The hunter gatherer network

By far, the largest part of human history is prehistoric: there was no written language, and the only information we have is based on archeological findings and the old stories …

Networks connecting humans

Humans are a very social species, and they interact a lot. These interactions may address the exchange of information, the sharing of norms, and the transmission of viruses, to name …

The Internet and Technology

Leading up to the industrial revolution, technology slowly evolved and, in particular, evolution in sailing contributed to the development of a vast network between people all over the globe. The …
