ভূমিকা
From the point of view of the scientific school of today, man is quite sure that not a single atom of the world of existence is outside the governance of general attraction, and none can escape it. From the largest of the world's bodies and masses to the smallest of its atoms, all possess this enigmatic force called the force of attraction, and all are, in some way, influenced by it.
Ancient man did not discover the universal general law of attraction, but he did discover attraction in some bodies, and recognized some things as symbolic of this force, such as the magnet and amber. Even so, he did not know of the relationship of attraction between these things and all other things, as he was only acquainted with a particular relationship: that of the magnet to iron, or amber to straw.
Each one of the atoms on atoms which exist between this earth and the heaven is, for its own kind, like straw and amber. [^1] Apart from this, there was no talk of the force of attraction with other inanimate bodies; only about the earth was it asked why it was fixed in the middle of the havens.
It was believed that the earth was suspended in the middle of space and was attracted on every side, and that since this pull was from all sides, it naturally stayed in the middle and did not incline to any one side.
