Bruno also was not much of a Copernican, or by most accounts much of an astronomer at all. His interests were theological, not physical, and his astronomical writings are considered amateurish and confused. He performed great feats of memory using an early form of mnemonics , he was accomplished in mathematics but also in magic, and he was a true theological and philosophical innovator in his vision of endless inhabited worlds. He was advancing his own, heretical theology, which goes a long way to understanding the real reason that he was burned at the stake.
The Roman Inquisition listed eight charges against Bruno. His belief in the plurality of worlds was just one.

The others involved denying the divinity of Jesus, denying the virgin birth, denying transubstantiation, practicing magic, and believing that animals and objects including the Earth possessed souls. You could fairly call Bruno a martyr to the cause of religious freedom, but his cosmic worldview was neither a deduction nor a guess.
It was a philosophical corollary of his heterodox belief that God and souls filled all of the universe. Despite his heresies, Bruno was neither impoverished nor alone.

In reality, he had a series of powerful patrons. In , he was appointed a professor of philosophy in Tolouse, France. In he visited England, lived with the ambassador to France, and met regularly with the Court…and so on.

The gaunt, lonely fellow you see on screen in Cosmos is not the real Bruno. Nor was Bruno the simple, humble figure shown on TV. A major reason he moved around so much is that he was argumentative, sarcastic, and drawn to controversy. He engaged in bitter academic disputes, many of which had nothing to do with his cosmic framework. One example He fled France because of a violent dispute about the proper use of a compass seriously. None of this means that Bruno in any way deserved his fate. But neither does he deserve to be reduced to a cartoon about intellectual freedom. He was a brilliant, complicated, difficult man.
Neither Johannes Kepler nor Galileo thought much of him. Digges was one of the leading astronomers in 16th century England—a place where Catholic doctrine obviously did not hold the kind of sway that it did in Italy. You might call him the Carl Sagan of his day.
Along with his translations, Digges added commentary and new ideas, making it clear that the Copernican model was more than philosophy, it was a physically real model of the solar system. Even more significant, it was Digges—not Bruno—who first broached the idea that a sun-centered universe could well be infinite in extent. If all revolved around the Earth, then the stars needed to be confined to a shell that could likewise circle around us once a day.
But if the Earth is in motion, then there is no reason why space could not be open and unbounded. Digges made this point explicit and even created a drawing showing, for the first time in history, how the stars might be scattered through endless space outside our solar system.

All of this seems very much in the spirit of Sagan: taking an audacious idea, explaining it to a broad audience, and citing philosophical precedent from classical Greek literature to show that the idea was not so heretical after all. Born and raised in New York City, Tyson became interested in astronomy at the age of nine after a visit to the Hayden Planetarium.
In , he joined the Hayden Planetarium as a staff scientist and the Princeton faculty as a visiting research scientist and lecturer. The U. Arguing that "the most powerful agency on the dreams of a nation is currently underfunded to do what it needs to be doing". Tyson has suggested that the general public has a tendency to overestimate how much revenue is allocated to the space agency. It's a half a penny on the dollar. Did you know that?

From kindergarten throughout high school, Tyson attended public schools in the Bronx: P. He recalled that "so strong was that imprint [of the night sky] that I'm certain that I had no choice in the matter, that in fact, the universe called me. He credited Dr. Mark Chartrand III, director of the planetarium at the time, as his "first intellectual role model" and his enthusiastic teaching style mixed with humour inspired Tyson to communicate the universe to others the way he did. Tyson obsessively studied astronomy in his teens, and eventually even gained some fame in the astronomy community by giving lectures on the subject at the age of fifteen.
