    He receives the prize for conceiving the IceCube neutrino detector, a cubic-kilometer-sized detecter in the Antarctics.

    Mechanism is via conversion of neutrinos into charged particles which are then detected via Cherenkov radiation which is produced when a charged particle moves with speeds larger then the speed of light in the medium. (That is only possible because it is less than the speed of light in vacuum which cannot be exceeded.)

    This was also discussed recently if you are interested: https://news.ycombinator.com/item?id=49655286

    As we celebrate the IceCube neutrino detector for wining this year Nobel Prize in Physics, people in my country India should feel lost for missing the opportunity to setup INO (https://en.wikipedia.org/wiki/India-based_Neutrino_Observato...)

    I'm in love with the cute little figure that came with the press release: https://www.nobelprize.org/uploads/2026/10/fig_fy_26_3x2.jpg

    I appreciate the boldness of this project, it has an element of sci-fi to it. Building a base at the south pole to bury sensors in ice to measure elusive particles. The stuff of dreams!

      To be fair, the base was already there and logistically essential. The IceCube topside building is just a part of the Amundsen-Scott South Pole Station, about a km or so from the Elevated Station.

      A trillion of these silly small guys pass through us every second. Funny to imagine them like that.

    The first time in as long as I can think that a single physicist was chosen.

      I wonder - was there really no other people they could have given it to? The detection of gravitational waves was split between a theorist, experimentalist and a person who had a big hand in shepherding the project along. Could not the same have been done here?

    We think of receiving a Nobel Prize as something super rare and exceptional and it is. What still always astounds me though, is this:

    There are nearly 300 living laureates. Enough to hold a yearly meetup for them in Lindau, where usually about 40 gather. This year, for the event's 75th anniversary, there were even about 70. Imagine that.

    Here's the APOD for IceCube back from 2011

    Last years favorite finally wins it this time. https://www.rtbf.be/article/avec-icecube-le-physicien-belge-... (2025)

    Oh, it's amazing that the AI didn't prize.

    Just happy it's not another AI related prize.

    Just woke up this morning to this news. Thank God. Today is a good day.
