+%% TODO: remove
+%% Some ideas to motivate the topic:
+%%  - Physics in a crystal lattice structure
+%%    - Birifrencenge and scattering of light / Xray in Crystals
+%%    - Electron density function in a lattice
+%%    - Heat diffusion with lattice model
+%%    - Ising model for ferromagnetism (?? => H.D. Lang)
+%%
+%%  - Homomorphic encryption (or lattice based cryptography)
+%%    + Q: Is it possible to edit encrypted data without decrypting it first?
+
+%% TODO: translated and move into a file {{{
