Wissenaire
Wissenaire is the annual techno-management festival of Indian Institute of Technology
Bhubaneswar held in the Arugul campus of the prestigious IIT Bhubaneswar. It is one
of the most awaited technical festival of East India. It is a three day long event usually
held during first week of January. The word Wissenaire is derived from the German
word ‘Wissen’ meaning knowledge and ‘air’ meaning free. Thus it is justified by its
tagline Knowledge Runs Free. Wissenaire encompasses various sectors of technology,
science and management. These including quizzing, coding, designing, robotics, planning
and testing the creativity and innovative spirit of young technical minds. With this
motive Wissenaire’17 is conducting Qwissenaire’17, the Talent Test to ignite minds of
8th, 9th and 10th class students.
