How to hide informations in randomness.
The BB84 protocol of quantum cryptography.
We discover a surprisingly simple, geometrical interpretation of the spin in four dimensions and an ambiguous interpretation in three dimensions.
We discuss the spectrum of the hydrogen atom.
We examine Chladni sound figures on circular glass plates of different sizes.
We discuss the structure of the periodic table by using the quantum organ.
We discuss symmetries of a cup’s standing waves.
We visualize the Pauli exclusion principle, explaining the stability of elements.
We describe the possible fundamental vibrations on a sphere’s surface by counting, mirroring and rotating nodal lines.
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.
We discuss approaching the quantum dimension by learning about quantum states and operators.
