(physics) A thought experiment linking general relativity and gravitational waves, based on the idea of two beads sliding freely (but with a small amount of friction) on a rigid rod. As the wave passes over the rod, atomic forces hold the length of the rod fixed, but the proper distance between the two beads oscillates. Thus, the beads rub against the rod, dissipating heat.

Japanese Meaning
物理学における思考実験。一般相対性理論と重力波の関連性を示すため、わずかな摩擦を伴う２つのビーズが、硬い棒上を自由に滑る様子を用い、重力波が通過すると棒の長さは原子間力の働きで固定されるが、ビーズ間の実際の距離は振動し、その結果ビーズが棒と摩擦し熱を発散する現象を説明する。
