...of those being able to occur near one another, it is clear that there is a certain understanding according to rarefaction araiōsin original: "ἀραίωσιν" (araiōsin). This describes the thinning of a substance as its particles move further apart, the opposite of compression.. And it will itself [be compressed], and the particles are interwoven; but a [continuous] void kenon original: "κενὸν" (kenon). Hero argues that while tiny gaps exist between particles, a large, empty space—a "continuous" vacuum—does not occur naturally. he says does not exist.
Therefore, the particles sōmata original: "σώματα" (sōmata), literally "bodies." Hero uses this to mean the fundamental physical units of matter. would have to increase. However, it is not possible that they increase, nor is such a conception consistent with them.
It is clear, then, from what has been said, that within the particles sōmasi of the air, there are certain small voids kena scattered throughout. When a certain force is applied, they undergo collapse? original: "συνίζησιν" (sunizēsin). This refers to a settling or shrinking together, where the particles move into the empty gaps. by yielding into these voids kena.
But the air being forced down into the water as a whole does not undergo much compression pilēsin original: "πίλησιν" (pilēsin), literally "felting." Like wool being pressed into felt, this refers to the packing together of particles..
For the forcing power is not sufficient. This is because water, by its own nature, has neither weight baros within itself, nor a violent outward pressure original: "ἔκθλαψιν" (ekthlapsin). This is the force that squeezes something out or away..
This is exactly what happens. Thus, when people are diving into the depths of the sea, even though they have an infinite measure [of water] there, their breathing is not d The insertion of the letter delta may be a scribal correction or a shorthand marker. forced by the water, even though a very small amount of air is trapped within the nostrils. It is worth investigating what the reason is that, as stated, those diving kolumbōntes into the depths are not crushed, despite having the infinite weight baros of the water pressing down on them. Some indeed say that it is because the water...
