for
operators
better interaction
and tour planning for teachersNowadays we have great tools to build computer games: we have powerful 3D graphic cards and great software – even open source!
Use gamification as
visualization tool!
Visualization is the fundamental
of all knowledge.(freely
adapted
from
Johann Heinrich
Pestalozzi,
1746
– 1827)
The
game is the way that children get to know the world in which they live
(and
which they are called upon to
change).

Slide16Physics and measurement principleNeutrino Physics
observation of neutrino oszillations → neutrinos have mass
Slide17Physics and measurement principleMeasurement principle: Tritium decay
released energy E0=18600 eV, shared between kinetic energy of electron and neutrino and the rest mass of the neutrino m(νe)the neutrino vanishes → measure energy E of electrons to get information about the neutrino mass m(
νe
)
the maximum possible electron energy E is E0- m(
νe)

Physics Education:excursions important for sensual and visual experience beyond theoretical and
scientific lessons
→ supports sustainable comprehension
Public Relations:
great public interest in large-scale research facilities
→ provide information and access to experiment sitesProblem:accessibility of the experimenttraveling time and costsProposed Solution: virtual reality (VR) visitsVR application prototype has been constructed:the KATRIN educational gameMotivation
