- Atoms:
Perrin's
experiments:
- Sedimentation - a model: a suspension of
microcristaline quarz (determination of Avogadro's number)
- Diffusion of oleic acid drop on water surface
(determination of atom diameter) [ringraziamento
a Dott. Romano Cainelli]
- Brown's movements (a drop of ink from jet
printer in water)
- Electrons:
- A piece of amber (electrostatics)
- Positrons - similar to electrons
but
different

- Quantum Mechanics:
- Planck's box (temperature of the "radiation
field")
- Wave Mechanics:

- Laser:
- He-Ne laser tube
- Ligh interference sun glasses - interference mirror
- Singing tube, excited by gas flame [Educational Innovations inc.]
- Symmetry CPT:
- Celtic stone
- Venetian gondola
- Franck-Hertz's experiment:
- Student experimental set-up from Gdansk University
[courtesy dr. Alicka]
- Gas discharge at intermediate pressure (a
few Torr) - light strands
- Bose-Einstein's condensation - three steps:
- Mexico top-spin on a flat dish (atom with
non-zero spin trapped in a shallow magnetic trap)
- Laser cooling. A rubin sphere surrounded
by polistyren spheres (Rb atom in optical "mollases")
- Evaporative cooling (forced coolling of
hot water cup - in B-E condensate this cooling is forced by
a RF absorption, leading to anti-bonded Zeeman states)
- Magnetic trap from Trento University
[courtesy dr L. Ricci]
- General relativity theory:
- A baloon on a wire circle, with a mass in
the center - bending of space-time near the "gravitational"
mass
- Gravitational funnel
(1/r2 field)
- Non-Newton funnels (fields
other than 1/r2)
- Simulation of 1/rn gravitational
fields

- Particular relativity theory:
- Shooting of rubber balls againts a wall -
in quiet and in movement (relativistic retard of moving clocks)
- "Smart car" - model (relativistic reduction
of longitudinal dimensions) [courtesy Paweł Karwasz]

- Lepto - Greek coin of 1 cent, weigth 2,29
g
[thanks to Bank of Greece, Nafplio Branch]
- Copper disk, weigth 0,47 kg (lepton mu;
