When a man can say definitely what he means by using a simple and appropriate word, why employ an inappropriate one that requires qualification and ultimately becomes transformed into something quite different? After the theory was banned he utilized it to galilfo in the truth by pretending as here that Copernicus had spoken falsely in attributing a nonexistent motion to the earth.

That is a very true statement, even though Sarsi appears to disbelieve it and acts as if acquainted with neither nature nor poetry. Now these and similar arguments, coming to me on the authority of those gentlemen, almost took away my resolve to write no more; yet my desire to live in tranquility prevailed.

But I do not think on that account that none can have taken place; it may have been too minute to be perceptible any balance whatever.

Guiducci was often present, and one day he told me that he had thought of speaking on comets before the Academy; if I liked, he would include what he had heard from me along with things he had gathered from other authors or had thought himself.

This is not derision; it is simply the statement of our opinion. At first he used his discovery in support of Copernicus. The primary qualities exist regardless of people, but the secondary qualities would disappear without living creatures to experience them—secondary qualities exist only in the experiencing body. falileo

Did it never enter your head to tell us to try looking at stars? When touched upon the soles of the feet, for example, or under the knee or armpit, it feels in addition to the common sensation of touch a sensation on which we have. I did not mean to spend so many words on this trifling, Your Excellency, but since the more has been done, the less remains to do.

In short, it follows that heat is a subjective or secondary quality that only exists because our bodies can interpret the moving fire-particles through touch, as they pass through our bodies.

Sarsi goes on to say that since this experience of Aristotle’s has failed to convince us, many other great men also have written things of the same sort.

Sarsi should not have undue trouble in understanding that even if all the material involved in a comet is equally illuminated, sunlight might be reflected to the eyes of one particular observer only from some particular part of it.

But assuming that this was Aristotle’s meaning, assaer still differs from Guiduccis; for to Aristotle any rubbing of bodies would suffice, even of tenuous ones or of the air itself, whereas Guiducci requires two solid bodies, for he considers that trying to pulverize the air is as great a waste of time as grinding water in the proverbial mortar.

There I wrote that in Venice, where I happened to be at the time, assayed arrived that a Fleming had presented to Count Maurice [of Assayeer a glass by means of which distant objects might be seen as distinctly as if they were nearby.

It is motion that causes wood to burn or metal to melt.

For any body resting freely in a thin and fluid medium will, when transported along the circumference of a large circle, spontaneously acquire a rotation in a direction contrary to the larger movement. I first noticed this when breaking the comers off a piece of glass and rounding it with a key or some other piece of iron. But from which of those sources the two authors mentioned by Sarsi derive the scarcity of their followers I do not know, for I have not studied their works gallieo to judge [7].

Now is this to be a skillful and prudent experimentalist? The purpose of this was to maintain the axis of the earth parallel to itself throughout the year in order to account for the seasons.

The Assayer

Should I not have been showing a wish to remain incognito? It is perfectly true that assayet lengthened telescope is a “different” instrument from what it was before, and this was essential to our point. In that way you will be able to find out just how much force human authority has upon the facts of Nature, which remains deaf and inexorable to our wishes.

It is my opinion that the original proposition may be quite true, taken in the simplest sense of the words it contains, and that perhaps it came from some good philosophical school of antiquity, but that Aristotle failed to fathom [p.

The notion was put forth so temperately by Guiducci that at the end he said, [p. This is quite a common figure of speech, as when one says: Views Read Edit Aszayer history.

Well, I lack the stomach for this and I freely confess this cowardice. The latter, I believe, are nothing more than names when separated from living beings, just as tickling and titillation are nothing but names in the absence of such things as noses and armpits.

At first they tried to persuade me not to be upset by obstinate attacks, saying that in the end those would rebound upon their authors and merely render my own reasoning more lively and attractive, furnishing as they did clear proof asssyer my essays were of an uncommon nature. Guiducci has written, “Many stars completely invisible to the naked eye are made easily visible by the telescope; hence their magnification should be called infinite rather than nonexistent.

In place of the thickness of a comet, merely ten yards will suffice. Consequently the more perfect it is the less attractive it will be, and the fewer its followers.

For they believe that heat is a real phenomenon or property, or quality, which actually resides in the material by which we feel ourselves warmed [19]. But first I must consider what it is that we call heat, as I suspect that people in general have a concept of this which is very remote from the truth.
