Sisu is an all-purpose philosophy of life and as such it underpins all aspects of the NREN community.
The Finnish word sisu is untranslatable, but overall it can be explained as a concept encompassing inner strength, tenacity, determination, and courage, particularly in the face of adversity.
In a changing world, the TNC26 theme seems very fitting: our community needs to embrace the idea of sisu to ensure our future as a community. With this action-orientated mindset, we need the courage to make difficult decisions about our response to world events, to ensure a sustainable future for our activities and to maintain the strong ecosystem we have built.
CSC – IT Center for Science builds digital solutions for data management, scientific computing, and education that help researchers, learners, and companies understand the world. CSC supports society’s digitalization and, on its part, promotes the green transition with our customers, owners, and partners.
CSC manages and operates Funet, a high-speed, cost effective academic and research network for Finnish higher education institutions, research organizations and other Funet members. Over 440 000 Funet community users use daily Funet services such as solutions for campus and wireless networking, cybersecurity and video technology. One of the world’s oldest NRENs, Funet (founded 1983) connects to other European NRENs and worldwide research networks through NORDUnet and GÉANT.
Located on the shore of the Gulf of Finland, Helsinki is a charming seaside city with a unique twist – a place where urban culture meets coastal nature. The easy-going Nordic lifestyle and friendly locals make it easy to fall in love with this northern city – the capital of the happiest country in the world!
TNC26 will be hosted at the Helsinki Music Hall (Helsingin Musiikkitalo in Finnish), a concert hall and a music center. The building is home to Sibelius Music Academy and two symphony orchestras, the Finnish Radio Symphony Orchestra and the Helsinki Philharmonic Orchestra.
