働きに敬意を表して Respect for buoyancy
Buoyancy is a force that acts against gravity on objects in a fluid. Buoyancy creates updrafts, resulting in atmospheric circulation and weather, supports the lives of underwater creatures by making them float, and shows plants the direction of gravity through the direction of buoyancy acting on density differences, and it seems to be the force that holds mountains and the earth together with its crust. In tribute to buoyancy.
