I missed a chance yesterday to note an anniversary. Giordano Bruno was something of a crank, not normally the sort of person I'd be commemorating. But in his time, it didn't take very much to be considered either of those, or worse, and we have to make allowances.
He was headstrong. We can see now that he was sometimes eerily right, other times totally wrong. Either way, many of these strongly held positions were sure sources of trouble for anyone who advocated them. All living things were made up of matter, and that matter was the same across the universe - that one was not going to go over well in the late 16th century.
There was more. The stars, he said, were nothing more than other suns, and our sun was nothing more than a nearby star. He saw no reason why these other suns should not have planets around them, and no reason why those planets should not have life: "Innumerable suns exist; innumerable earths revolve around these suns in a manner similar to the way the seven planets revolve around our sun. Living beings inhabit these worlds."
He went on at length. And as I said, much of it was, by scientific standards, mystical rot. His personality was no help whatsoever in getting his points across. He appears to have eventually gotten on the nerves of everyone he dealt with. But no one deserves to pay what he did for it all.
Bruno was excommunicated and hauled off in chains. He spent the next several years in prison, and was given chances to recant up until the very end. He refused. On February 19th, 1600, he was led into the Campo dei Fiori plaza in Rome, tied to a post, and burned to death in front of a crowd.
Mystic, fool, pain in the neck. I went out tonight to see Saturn disappear behind the dark edge of the moon, putting the telescope out on the driveway and calling my wife out to see. Then I came inside, sat down at my computer, wrote exactly what I thought, and put it out for anyone who wanted to read it around the world. While I did all that, I remembered that things haven't always been this way, haven't been this way for long at all, actually. And resolved to remember to enjoy it all as much as I can, and to remember those who never got to see it.
