In nature, groups of individuals organize globally using only local information.
For instance, in a school of fish, there are no external forces to coordinate the group, no leader to guide them.
Several mathematical models have been proposed to describe self-organization.
In this talk, we will consider two of the most famous models; the Keller-Segel model
for bacterial chemotaxis and the Cucker-Smale model for flocking.
The emphasis will be on recent mathematical results and remaining open questions.
Starting from the microscopic description on particle level,
we will discuss the derivation of mesoscopic and macroscopic models
at the continuum level. Since the motivation for deriving
continuum models is largely numerical, we will also
discuss distinct numerical challenges with the resulting models.

The gas pipeline from the Ormen Lange Field to the terminal at Aukra faced several challenges. First, the terrain was very rugged as the route goes through the Storegga slide area where unprecedented long free spans were to be expected. Secondly, the area was believed to have complicated and strong ocean currents. An oceanographic campaign was started in 1999 and lasted to 2007. The presentation will give some background for the measurements, describe the programme and show some results.
