“So mathematical truth prefers simple words since the language of truth is itself simple.”

There had never before been any star in that place in the sky.

it seems that the complete explanation of the whole matter is not given unless we are also informed within narrower limits in what part of the widest Aether, and next to which orbs of the Planets [the comet] traces its path, and by what course it accomplishes this.

Because the region of the Celestial World is of so great and such incredible magnitude as aforesaid, and since in what has gone before it was at least generally demonstrated that this comet continued within the limits of the space of the Aether.

It was not just the Church that resisted the heliocentrism of Copernicus.

With a firm and steadfast mind one should hold under all conditions, that everywhere the earth is below and the sky above and to the energetic man, every region is his fatherland.

Lastly, the star became like Saturn, and there will finally come a time of want, death, imprisonment and all sorts of sad things.

The mouse is wise, but the cat is wiser.

So that such ideas are opposed both to physical principles and to the authority of the Holy Writ which many time: confirms the stability of the Earth (as we shall discuss more fully elsewhere).

When I had satisfied myself that no star of that kind had ever shone before, I was led into such perplexity by the unbelievability of the thing that I began to doubt the faith of my own eyes.

From his observations, he concluded that it [Tycho’s supernova] was not some kind of comet or a fiery meteor, whether these be generated beneath the Moon or above the Moon, but that it is a star shining in the firmament itself.

Now it is quite clear to me that there are no solid spheres in the heavens, and those that have been devised by the authors to save the appearances, exist only in the imagination.

That the machine of Heaven is not a hard and impervious body full of various real spheres, as up to now has been believed by most people.

Those who study the stars have God for a teacher.

An astronomer must be cosmopolitan, because ignorant statesmen cannot be expected to value their services

One that has never previously been seen before our time, in any age since the beginning of the world.

The star [Tycho’s supernova] was at first like Venus and Jupiter, giving pleasing effects; but as it then became like Mars, there will next come a period of wars, seditions, captivity and death of princes, and destruction of cities, together with dryness and fiery meteors in the air, pestilence, and venomous snakes.
