<human>:  Where does the centrifugation come from in the technique called ‘Centrifugation’?
<bot>: Centrifugation is a technique used in chemistry and biology to separate mixtures. It is based on the principle that a particle will move towards a region of higher gravitational potential. In a centrifuge, a mixture of particles is placed in a rotating container and the container is spun at a high speed. This causes the heavier particles to move towards the center of the container, while the lighter particles move towards the outside of the container.
