What is called "sponge stone" or "Pompeian pumice" appears to have been reduced by burning from another kind of stone to the condition of the kind which we see. The kind of sponge-stone taken from this region is not produced everywhere else, but only about Aetna and among the hills of Mysia which the Greeks call the "Burnt District," and in other places of the same peculiar nature. ...it seems to be certain that moisture has been extracted from the tufa and earth, by the force of fire, just as it is from limestone in kilns.

Peter, in showing that the Church is one and that only those who are in the Church can be saved, said: "In the Ark of Noah certain persons, numbering only eight, were saved by water, which Baptism effects in like manner for you" (1 Peter 3:20). He proves and demonstrates that the solitary Ark of Noah was the figure of the One Church. If, at the time of this Baptism of the world anyone could have been saved without having been in the Ark of Noah, then he who is outside the Church could now be brought to life by Baptism.
Cyprian
If someone offends you, don't tell anyone about it except your elder, and you will be peaceful. Bow to everyone, paying no attention whether they respond to your bow or not. You must humble yourself before everyone and consider yourself the worst of all. If we have not committed the sins that others have, perhaps this is because we did not have the opportunity - the situation and circumstances were different. In each person there is something good and something bad; we usually see only the vices in people and we see nothing that is good.
Ambrose
We must, with God's help, eradicate the deadly poison of the demon of anger from the depths of our souls. So long as he dwells in our hearts and blinds the eyes of the heart with his somber disorders, we can neither discriminate what is for our good, nor achieve spiritual knowledge, nor fulfill our good intentions, nor participate in true life; and our intellect will remain impervious to the contemplation of the true, divine light; for it is written, 'Man's anger does not bring about the righteousness of God' (Jms. 1:20).

In the groundes bordering uppon tile woods of Arden, which are verie colde, they use lime instead of dung, and thereby they make ye earth most fruitful which was barren before, Now if lime (which is nothing else but a baked or burnt stone within those fierie furnaces, and whose moisture is altogether exhaled, so as there remaineth therin nothing else, but the terrestriall parts replenished with a fierie vertue) be found so rich a soile, I know not why the heat of marle may not nmch better be endured.

When two identical He atoms collide... the interference is destructive. Particles that behave like He atoms are called fermions, short for "particles obeying Fermi–Dirac statistics." ...while bosons imitate one another... the "identity force" between fermions acts like a repulsion, and the probability of finding a fermion at some point in space is reduced if some of its identical siblings are nearby. ...It is the repulsive identity forces between electrons that support white dwarf stars... against their own gravity.
