Dice Become Ordered When Stirred, Not Shaken

A jumble of thousands of cubic dice, agitated by an oscillating rotation, can rapidly become completely ordered, a result that is hard to produce with more conventional shaking. A twist of the dice. Sufficiently vigorous twisting of a cylinder containing 25,000 randomly-oriented dice (left) leads to a nearly perfectly ordered arrangement (right). The more conventional technique of tapping the syst

ざらざらサイコロ流し込んだ円筒を反転させつつ10万回転させるとみっしり詰まる 詰まるかどうかは反転時の加速度に依存してて、閾値下回るといつまでも(10年以上とか)詰まらない。 いろんな統計力学的な物理現象に繋が
