When
you sunbathe, you also take a neutrino shower:
100,000 billion pass through your body every
second. Statistically speaking, your body will
stop only one of the many neutrinos which pass
through it during a lifetime.

What makes the
sun shine?
Light from the sun's hot
surface allows life to flourish on our planet. The
heat is provided by fusion processes in its dense
core. Atomic nuclei of hydrogen fuse together into
helium nuclei. For each helium nucleus produced,
energy is released together with two
neutrinos.
"Through the
vista-windows suns peer in at us,
looking calm of eye, although we know,
their thunderous roars amid the roentgens
blasting,
their flailings in the gorge of
everlasting."
Harry Martinson, Nobel Prize Laureate in
Literature 1974
- Poem 62 from 'Aniara', 1956
(translation by Stephen Klass and Leif Sjöberg,
published by Story Line Press)
