In order to avoid equivocation Sarsi needed to give his classification at least three parts, and say: Sarsi has seen it proved in my Starry Messenger that the earth itself shines more brightly than the moon.

I believe that in the weaving of this cloth, Sarsi is going to get himself so entangled-far more than he supposes now, while he is laying the warp-that in the end he will voluntarily admit himself defeated.

You say there [p. If the ruffling goes on to form greater and greater waves, the multitude of mirrors from which the image of the sun will be reflected will extend over wider and wider spaces. When these small corpuscles cease to move, then there is no more heat. Did it never enter your head to tell us to try looking at stars? Well, if we cannot have the presence of your poets who, as I say, would yield to experiencewe do have at hand archers and catapultists, and you may see for yourself whether citing your authorities to them can strengthen their arms to such an extent that the arrows they shoot and the lead balls they hurl Win take fire and melt in the air.

Guiducci, in his discussion of the telescope, is said either to have included an effect which does not exist or to have left out one that should be given. During the entire time the comet was visible I was confined by illness to my bed.

He seems not to know that fables and fictions are in a way essential to poetry, which could not balileo without them, while any sort of falsehood is so abhorrent to nature that it is as absent there as darkness is in light. Here are the steps of the argument.

Assayeg believe that it aassayer be one of the latter who is hidden behind the mask of “Lothario Sarsi,” for if he were one of the former it would indeed be poor taste for him to impose upon the public in this manner. On a lute, one galoleo will do what many strings on a harp will do; for in fingering the lute the sound is drawn now from one part of the string and now from another, which is the same as lengthening and shortening it, and making of it different strings so far as relates to the production of sound.

Sounds are made and heard by us when the airwithout any special property of “sonority” or “transonority” -is ruffled by a rapid tremor into very minute waves and moves certain cartilages of a tympanum in our ear.

The Assayer

It is written in the language of mathematics, and its characters are triangles, circles, and other geometrical figures, without which it is humanly impossible to understand a single word of it; without these, one is wandering around in a dark labyrinth.

For my own part, never having read the pedigrees and patents of yalileo of shapes, I do not know which of them are more and which are less noble, nor do I know their rank in perfection. But it was in vain that I had reached this frame of mind, and by remaining silent I could not evade the stubborn fate of having to concern myself continually with men who write against me and quarrel with me. But let us see how conclusive they are. Waves are propagated very rapidly in this way, and high tones are produced by frequent waves and low tones by sparse galielo.

The method win be to make the tube in sasayer pieces, one inserted in the other. But I hold it to be silly to accept that proposition in the ordinary way, as if a stone or piece of iron or a stick must heat up when moved.

Philosophy is written in this grand book, the universe, which stands continually open to our [p. But even on that assumption, I do not see why he selects Tycho.

This will happen when the specific gravity of that which is consumed is less than that of the medium assyaer which it is being weighed.

Why has he considered me the author of this Discourse without showing any respect for that fine man who was? Of bodies that are rubbed together, some are certainly not consumed, others are quite perceptibly consumed, and still others are indeed consumed, but insensibly.

Meanwhile I say, in order not to discourage him, that if what he is attempting turns out to be correct, then this reasoning which his teacher and his astronomer friends use to determine the location of the comet is not only the most ingenious argument of all, but such an employment of the telescope far transcends all others in the importance of its consequences.

Irregular lines are those which have no determinacy whatever, but are indefinite and casual and hence undefinable; no property of such lines can be demonstrated, and in a word nothing can be known about them. Hence I say it may happen that the parts left will weigh more in water than the entire piece of wood did.

For my part I do not merely excuse him, I praise him; for to me it appears he has accomplished the impossible. It is perfectly true that the lengthened telescope is a “different” instrument from what it was before, and this was essential to our point. Will he say that this comes about because they are made of different materials?

Guiducci and I may concede the whole thing to him without prejudice, as we have never said anything about the location of the comet, nor have we denied that it might have been beyond the moon. Assuming that what Sarsi sees in his mirror is not a true and real man at all, but just an image like those which the rest of us see there, I should like to know the visual differences by which he so readily distinguishes the real from the spurious.
