Sicherman Dice
These dice have the numbers 1-2-2-3-3-4 and 1-3-4-5-6-8, but give the same sums with the same probabilities as two normal 1-to-6 dice. The only difference is the odd of rolling a double which as usually 6/36 are 4/36 for the Sicherman dice.

Seebeck effect
Thermoelectric generation using a Peltier Module to utilize the Seebeck effect to generate voltage. When heat is applied to one of the two semiconductors, heated electrons flow toward the cooler semiconductor. If the pair is connected through an electrical circuit, direct current flows through that circuit.

Shapes of Molecules
The shape of the molecule affects the shape of the crystal. Modelling using dice shows how different shapes can and can't fit together and gives rise to the crystal shapes we observe.
