'From ice to diamonds, all crystals in the universe exhibit 14 types of symmetries — ways their atomic lattices can be rotated, translated or reflected into indistinguishable positions.

Stephen Hawking - This is the most dangerous time for our planet
'Climate change, food production, overpopulation, the decimation of other species, epidemic disease, acidification of the oceans.
