Congratulations to Francis Halzen! He was so clear why
(1) neutrinos are the only way to do astronomy in dense environment with pointing
(2) neutrinos are likely to be generated by high-energy astrophysics as "beam dump" experiments
(3) big chunks of ice or water are the only way to go
and many people got convinced by the crazy idea. And he made it happen! A well-deserved honor. He is such a nice guy, too.
