Alice Chessboard Code
Alice key to the Chessboard Code.
One time pad
How to hide informations in randomness.
Quantum Cryptography
The BB84 protocol of quantum cryptography.
Quantum Nodes
We discover a surprisingly simple, geometrical interpretation of the spin in four dimensions and an ambiguous interpretation in three dimensions.
Atomic Spectras
We discuss the spectrum of the hydrogen atom.
Chladni Sound Figures
We examine Chladni sound figures on circular glass plates of different sizes.
Periodic Table
We discuss the structure of the periodic table by using the quantum organ.
Vibrating Cup
We discuss symmetries of a cup’s standing waves.
Pauli Exclusion Principle
We visualize the Pauli exclusion principle, explaining the stability of elements.
Spherical Harmonics
We describe the possible fundamental vibrations on a sphere’s surface by counting, mirroring and rotating nodal lines.
Stern-Gerlach Experiment
We examine the first experiment ever that proved the quantum nature of the spin – the Stern-Gerlach experiment. Additionally, we find an interesting analogy to polarized photons.
States, Operations and the Hydrogen Atom
We discuss approaching the quantum dimension by learning about quantum states and operators.
