excellence in science
More than 145,000 customers in more than
95 countries – mainly universities, colleges,
schools, private institutes, museums, and sci-
ence centers – have chosen PHYWE solutions.
... Göttingen is the town with the most Nobel
Prize winners in Germany.
There is no other place in Germany where one can
refer to their knowledge and scientific culture like
in this town. Otto Hahn, Lise Meitner, Max Planck,
Werner Heisenberg, and many more all worked
and lived in Göttingen and established the city’s
reputation as a university and cultural town. The
Georg-August University, Göttingen has a top-
reputation - worldwide. It is regularly in the top
50 ranking of elite universities and lures inter-
national experts in science to Göttingen to teach
and do research here.
Göttingen is where PHYWE is based. Our good
name along with the synonym for quality “made
in Germany” enabled us to become a global
market leader in education, teaching, and re-
search in natural sciences. With a long tradition
of nearly 100 years, PHYWE develops, produces,
supplies, and installs experiments, solution sys-
tems, scientific equipment, but also e-learning
systems, software, and services such as training,
installation, pre- and after-sales support, and
technical consulting.

Fundamental Discoveries of Nobel Prize Winners -
What they discovered and how they affect our lives
the importance of the discoveries of Nobel
laureates for the sciences and our lives.
The new topic “Nobel Prize Experiments” can
attract many visitor groups to these courses.
The incentive of the visit is to learn about and
understand the experiments and the scientific
theory behind them as well as to gain a deeper
insight into their scientific background.
Nobel Prize winners have revolutionized science

Principle
Osmosis is the movement of water molecules
through a selectively-permeable membra-
ne against a concentration gradient. It is a
colligative effect – its property depends only
on the concentration of the solute not on its
identity. In an osmosis chamber this effect
can be demonstrated. When water molecu-
les migrate through the membrane towards
the hypertonic solution – down the water
potential gradient – an osmotic pressure is
generated which can be followed observing
the rising water line in the capillary. Osmosis
is highly relevant for biologic systems as many
biological membranes are semipermeable
and the osmotic pressure inside cells ensures
their stability.
What you can learn about
■ Colligative effect
■ Osmotic pressure
■ Membrane

Related Experiments by PHYWE
Principle
The “Zeeman effect” is the splitting up of the
spectral lines of atoms within a magnetic field.
The simplest is the splitting up of one spectral
line into three components called the “normal
Zeeman effect”. In this experiment the normal
Zeeman effect as well as the anomalous Zee-
man effect are studied using a cadmium spectral
lamp as a specimen. The cadmium lamp is sub-
mitted to different magnetic flux densities and
the splitting up of the cadmium lines (normal
Zeeman effect 643.8 nm, red light; anomalous
Zeeman effect 508,6nm, green light) is investi-
gated using a Fabry-Perot interferometer. The
evaluation of the results leads to a fairly precise
value for Bohr’s magneton.

Principle
The relationship between the angle of scatte-
ring and the rate of scattering of alpha-par-
ticles by gold foil is examined with a semicon-
ductor detector. This detector has a detection
probability of 1 for alpha-particles and virtually
no zero effect, so that the number of pulses
agrees exactly with the number of alpha-par-
ticles striking the detector. In order to obtain
maximum possible counting rates, a measu-
rement geometry is used which dates back to
Chadwick. It is also possible in this case to shift
the foil and source in an axial direction (thus
deviating from Chadwick’s original apparatus),
so that the angle of scattering can be varied
over a wide range. In addition to the annular
diaphragm with gold foil, a second diaphragm
with aluminium foil is provided in order to
study the influence of the scattering material
on the scattering rate.

The synthesis of ammonia from elemen-
tal nitrogen and hydrogen based on the
industrial Haber-Bosch process is shown
in this experimental set-up in a simplified
way. This reaction was invented by Fritz
Haber and Carl Bosch using iron as catalyst.
It was the first method to convert chemically
inert dinitrogen into reactive ammonia on
large scale. Without catalyst, this reaction
is kinetically disfavored and takes place in
only very bad yields. Ammonia is for ex-
ample used as a ground chemical for the
production of fertilizer underlying the high

Haber-Bosch process.

years now. The fact that this radiation cannot

Principle
A beam of potassium atoms generated in a
hot furnace travels along a specific path in
a magnetic two-wire field. Because of the
magnetic moment of the potassium atoms, the
nonhomogeneity of the field applies a force at
right angles to the direction of their motion.
The potassium atoms are thereby deflected
from their path. By measuring the density of
the beam of particles in a plane of detection
lying behind the magnetic field, it is possi-
ble to draw conclusions as to the magnitude
and direction of the magnetic moment of the
potassium atoms.

not only the amplitude but also the phase of

beam (laser light) is split into an object and
a reference beam by being passed through a
beam splitter. These beams interfere in the

the fibre is recorded. The transit time of light
through the fibre is measured and the velocity

the measurement of the relative output power
