Its difficult to say how many mountains in the world have never been climbed - probably thousands. Breaking new ground is always exciting, whether in mountaineering or mathematics. We'll talk about our experiences making several first ascents of unclimbed peaks in the Indian Himalaya and the Kyrgyz Tien Shan, and some of the surprising similarities to our other lives in research and development. We'll cover some of the specifics of pulling off a climbing trip further afield than the Alps, and also talk generally about big projects in unknown territory.
