…totally cracks me up. Here is her essay On Being Asian, from which I quote:

Another issue I have is that I forget that I AM ASIAN. Seriously. I forget that I don’t look like you other white people. Maybe that’s why I hate dealing with immigrant Asians because they always ask the same questions: “Are you Chinese? You’re not? Because you look Chinese!” I never know what to say. Is there a blood test that I can take to find out? The other question is always: “Are you married to a white man?” (Yes.) I don’t know why the questions are always the same. Is there some kind of Asian Adoptee survey going on that I don’t know about? Because if there is? I’VE ALREADY TAKEN IT.

Moyers interviews Jon Stewart

This is a great interview with Jon Stewart by Bill Moyers on PBS. Watch it, but here is small tidbit for you.

JON STEWART: But war that hasn’t affected us here, in the way that you would imagine a five-year war would affect a country. I think that’s why they’re so really — here’s the disconnect. It’s sort of this odd and I’ve always had this problem with the rationality of it. That the President says, “We are in the fight for a way of life. This is the greatest battle of our generation, and of the generations to come. “And, so what I’m going to do is you know, Iraq has to be won, or our way of life ends, and our children and our children’s children all suffer. So, what I’m gonna do is send 10,000 more troops to Baghdad.”

So, there’s a disconnect there between — you’re telling me this is fight of our generation, and you’re going to increase troops by 10 percent. And that’s gonna do it. I’m sure what he would like to do is send 400,000 more troops there, but he can’t, because he doesn’t have them. And the way to get that would be to institute a draft. And the minute you do that, suddenly the country’s not so damn busy anymore. And then they really fight back, and then the whole thing falls apart. So, they have a really delicate balance to walk between keeping us relatively fearful, but not so fearful that we stop what we’re doing and really examine how it is that they’ve been waging this.

Congress to Bush: Yeah, we know.

What Congress is (hopefully) saying to Bush:

Yes, Mr. President, we know you disagree with us. We don’t give a shit. Your leadership has been abysmal, your judgment has been poor, your Vice President has been completely fucking wrong on everything he has said for years now. Your credibility is shit. We no longer think you are the man to handle the job. So, you can either cooperate with our agenda, which the American people completely support, or we can up the ante a bit and impeach your incompetent ass. Choose.

Congress to Bush: Yeah, we know.

Astronomy Matters

(It’s Astronomy Day today and on that theme I’m posting a little essay I wrote years ago describing my interest in astronomy.)

To tell you the truth, people are not that surprised that I am interested in astronomy. I think all people find astronomy fascinating. After all, it is the true nature of the universe. All of our world views have to take into account the vastness of the universe, the enormous time scales and distances and the seemingly insignificant and relatively instantaneous event that we call our lives. The universe is more strange and awesome than we can imagine. People use the word “astronomical” in their everyday lexicon to mean, in many cases, unimaginably immense. To me the question is not why are people interested in astronomy, but why aren’t all people?

It is interesting that for many people to contemplate the universe brings them face to face with God. They feel that this is God’s creation. I don’t think they are wrong but, like Carl Sagan, I tend to want to save a step. Rather than leaving the question “who created God” unanswerable, I choose to leave the question “who created the universe” unanswerable. To me, studying the universe does not reveal the mystery of God, it reveals the capabilities of human beings. We have learned so very much about things that we can never touch and can barely see. The science of astronomy is a story of the undaunted brilliance of people with a passion to understand. This is my passion: to understand the universe. I may never contribute one significant thing to the science. I’m sure my name will never appear in a text book or on a comet. But I will understand, and I’ll understand the hard stuff, too. Quantum mechanics and relativity are not by any means beyond our reach. Astrophysics is not beyond our reach. Any person can understand these things if they truly desire to.

My story begins, like many, when I was a young child with a telescope. It was a cheap telescope and gave me more frustration than pleasure, but it was the start of looking up. Later in life I felt my passion returning and a gift from my then girlfriend (now wife) of a 4.5″ Newtonian reflector got me on my way. I started as many do looking at Messier objects and reading every astronomy book I could get my hands on. I learned the constellations, how to recognize the planets and how to find many galaxies, clusters and nebulae with my first telescope.

For me, though, I was not getting enough photons. Objects do not look in telescopes like they look in photographs. Most are dim, fuzzy blobs that are barely visible. My next step was taking pictures of astronomical objects with a common camera. You can take some great pictures of some great objects with a common camera. This method of photography is called “piggy back” because you attach your camera to a telescope and use the telescope to keep the camera pointed at the object as the earth turns, a process called guiding. The camera uses its own lens and is not coupled to the optical system of the telescope.

The next step was using a camera attached to the telescope optically, which is called “prime-focus”. Here the telescope acts as the lens of your camera. This gives you much more light due to the larger nature of the telescope aperture, which in turn gives you better resolution of fine details. Prime-focus photography is much more difficult that piggy-back photography, but the results are stunning.

As I started to take more and better pictures of this freaky universe, I felt myself reaching a bit of a wall. The process of taking these pictures is enjoyable and exacting, but is not astronomy in the actual definition of the word. I wasn’t really studying or researching anything, I was just taking pretty pictures. I still love imaging and I consider it a great thing, because it brings the universe home to us in a way we can share with people. But my understanding of astronomy was not progressing. I felt it was time to start getting ready to study astronomy in the true sense of the word, and this means learning the language of astronomy, which is mathematics. To that end, I started taking classes at the University of Minnesota. I have a degree in music and needless to say, we did not study a lot of heavy math and physics in music school. I have started to take Calculus and Physics courses. More on that here.

I knew, though, that it would take me years and years to get to the point where I could study astronomy in the “professional” sense of the world. What could I do in the meantime? It didn’t take much looking to find the answer: study variable stars. It turns out that amateurs like me can make important contributions to science, and learn a lot along the way, by taking measurements of variable stars with a CCD camera. A CCD camera is a special kind of digital camera that is used for astronomy. (CCD means “charge coupled device” and you find them in common digital cameras, camcorders and scanners). There are so many stars in the sky and comparatively little time on “professional” telescopes that professional astronomers can’t really cover all the objects all the time. While some professional astronomers look down their noses at us silly little amateurs with our silly little telescopes, most do not. They appreciate the vast coverage that amateurs are capable of and use our data to correlate observations they make with rare large telescope time. On my research page I have some of the light curves and data that I have gathered. I intend to continue working with the AAVSO, the CBA and other loose-knit collaborations to gather, analyze and publish data on variable stars.

So now you know. Astronomy is the study of the true nature of the universe. It is the most important thing in the world. It is as frivolous as music and as serious as religion. Astronomy matters.

Not quite comfortable with moderation

Teresa over at Making Light has a long post and now a certificate (notably posted over at PZ’s site just now) about how we should all feel free to moderate whoever the hell we want whenever the hell we want.

Now she certainly sounds like a reasonable person and the analogy of a host at a party maintaining some sort of enjoyable environment for the guests and the responsibility of the guests to defer, somewhat, to the host is a good one. I get it.

But something in me still is uncomfortable with it. It is a big, fat license for people to “moderate out” those things that make them uncomfortable. The all-powerful blogger can pick and choose who has a voice and who does not.

You see, I don’t trust people to handle severe criticism well. We all tend to take things personally. We are all convinced of our own good intentions but suspicious of the intentions of our adversaries. This is human nature.

We are all capable of ignoring the assholes. I skip far more blog comments than I read. I’m not convinced I need help choosing which comments to read. While there are obviously trolls and assholes out there, there are also a lot of thin-skinned people, both bloggers and commenters, who get way too emotionally connected to these debates.

I’d personally rather wade through comment noise than miss perhaps provocative posts that made someone uncomfortable. We’re grownups.

I’m not saying that moderation is always bad, but I think our guiding principles should be first about commenting respectfully and secondarily, if at all, encouraging bloggers to delete comments.
