Of the mass of atoms, also he said “The more any indivisible exceeds, the heavier it is. ” But his exact position on weight of atoms is disputed.

He well known from his paradoxes. The most famous are the arguments against motion. The first one is the Achilles which is In a race, the quickest runner can never overtake the slowest, since the pursuer must first reach the point whence the pursued started, so that the slower must always hold a lead.
The second one is the dichotomy paradox which is a runner will never reach the stationary goal line of a racetrack. The reason is that the runner must first reach half the distance to the goal, but when there he must still cross half the remaining distance to the goal, but having done that the runner must cover half of the new remainder, and so on. If the goal is one meter away, the runner must cover a distance of 1/2 meter, then 1/4 meter, then 1/8 meter, and so on.
The third one is the Arrow, which is if everything when it occupies an equal space is t rest, and if that which is in locomotion is always occupying such a space at any moment, the flying arrow is therefore motionless. The forth one is the moving rows, concerning the two rows of bodies, each row being composed of an equal number of bodies of equal size, passing each other on a race- course as they proceed with equal velocity in opposite directions, the one row originally occupying the space between the goal and the middle point of the course and the other that between the middle point and the starting-post.
