Inside Japan's Big Physics | Part one: Super Kamiokande

Ғылым және технология

In the first of a new three part series, we go behind the scenes of Super Kamiokande, the world’s largest neutrino detector.
For more than half a century, Japan has been at the forefront of 'big physics', asking fundamental questions about the laws which govern the workings of the universe. Questions of this magnitude require cutting edge technology on a truly massive scale. Over three episodes, Nature reporter Davide Castelvecchi travels across to Japan to get a rare look inside three of its flagship experiments.
Part two: KAGRA - • Inside Japan's big phy...
Part three: Belle II - • Inside Japan's big phy...

    Antimatter is just matter with same properties except charge, for example positron, is just an electron but positive. In the case of neutrinos, it's kinda difficult, because they don't have charge, so some say, antineutrinos are the same as neutrinos, i don't know how the difference them tho.
