abstract = {Imagine you leave this lecture hall, some mean looking guys
dressed entirely in black follow, kidnap and take you to the
medieval castle of Nideggen in the close-by Eifel mountains.
There you are being thrown into a pitch dark dungeon. You
cannot see anything, but you hear some noises. Are there
rats? Are there other prisoners? Are there dragons? Luckily
you remember that you have some matches in your pocket. You
light a match, you can see everything around you and
everything becomes clear to you… What I have just
described is essentially like a scattering experiment:
figuratively it sheds light into darkness and helps us
understand the world around us. Let’s analyse what you did
in the dungeon: first when you light the match, you start a
source of radiation. Here the radiation is light. This light
then gets scattered (reflected, transmitted) from the
surrounding objects. In a scientific scattering experiment,
we will call this object a “sample”. Back to the
dungeon: some of this radiation gets scattered into your
eye. Your eye serves as very special radiation detector:
with its lens, it is able to even make an image of the
objects on the retina, which in the language of a physicist
would be called an “area position sensitive pixel
detector”. This image contains lots of information: the
colour of the backscattered light tells you something about
the absorption of certain components of the light and
therefore gives information about the material the light is
scattered from. The position of the signal on the retina
gives you information about the spatial arrangement of the
objects around you. And finally the time dependence of the
signal tells you that the monster is actually crawling
towards you, ready to attack. All this information has to be
treated and interpreted. This is done by our brain, an
extremely powerful computer to analyse this wealth of
data....},
