"Just thinking of sizes and distances in space is just mind blowing and impossible to grasp, but also what makes astronomy so very interesting" – Jonas Thoen Faber.

"What fascinates me most about astronomy are the physics and phenomena that are far away from what we experience in our day-to-day lives" – Edvarda Harnes.

Computing and software are crucial parts of the LHC physics experiments. The NorduGrid Advanced Resource Connector (ARC) middleware increases in popularity due its simplistic design and ease of deployment. This makes it the preferred choice of middleware for new and many existing sites particularly in Europe and Asia. ARC and its Control Tower allow seamless access to heterogeneous resources: Grid, High Performance Computers and Clouds. Moreover, ATLAS@home, based on BOINC and ARC, allow to access opportunistic resources made of personal computers.

The requirements imposed on software during the coming LHC runs will be as stringent as those on the computing resources. The data throughput that will have to be achieved exceeds anything that our community has managed to date. Such performance can only be attained by combining a number of techniques - multi-threading and parallel processing of events - as well as novel algorithms and optimization of existing software.

The importance of multi-variate analysis or "Machine Learning” in High Energy Physics continues to increase, for applications as diverse as reconstruction, physics analysis, data quality monitoring and distributed computing.

"That light carries information over extreme distances and explains faraway events! That's what fascinates me about astronomy" – Elias Roland Udnæs.
