Moon mining
Here's a couple of posts on Moon matters: first a private company plans to start mining the Moon by 2020; and second the Moon apparently has significantly more water than previously thought, which could allow lunar colonies to be self-supporting in that regard.

Life
Update: OK, I've had the idea for a series of posts like this for years, labelled "life," with a gif or video showing futility or panic or failure or pain or something along those lines. I finally kicked it off with the post below of Kermit the Frog frantically flailing his arms around, but immediately realized that most people wouldn't see it as panic or chaotic but as what it actually is: Kermit yelling "Yay!" after introducing the Muppet Show and its guest star. So it looks like I was saying life = celebration, which is the exact opposite of what I wanted. Then I did this one as a video because I think the music makes it. But at about the same time I posted it, I received in the mail The Year's Best Science Fiction, 34th Annual Collection by Gardner Dozois, the most recent addition to the series. I pre-ordered it a month and a half ago when my wife found a Barnes and Noble gift card and let me use it to buy volumes 32 and 34 (thank you Sweetheart). And it made me so happy to hold the book in my hand that I realized this whole idea behind a series of posts equating life with bad things was wrongheaded. So basically God told me to stop being such a pessimist. Yes sir.
Update (August 6): Oh my gosh, I just realized I'd posted this video five years ago.

A Tale of Two Movies . . . and Two Prayers
Last week I finally broke down and watched United 93. It's a real-time portrayal of the fourth plane hijacked on 9/11, the one where the passengers tried to take it back and ultimately stopped the hijackers from crashing the plane into their target (probably either the Capitol building or the White House). It is pretty hard to watch. I was living in Europe when this movie came out, and at the time I knew I wouldn't be able to handle it. I talked with another expat who felt the same way, but we thought maybe if we saw it together we could get through it. However, he lived too far away and we never actually followed up on it. In reading about the film and the events they portray, I learned some interesting things. In one of the phone calls made by a passenger, he said they were going to charge the terrorists, not to try to save their own lives but to stop them from reaching their target. This is awesome and humbling. I'm sure they hoped to somehow take back the plane and land it, but just the fact that stopping the terrorists played a role in their decision to fight back is amazing. I also learned that passengers from some of the other planes also said on phone calls that some of them were thinking of trying to take their planes back too. This was before they even knew they were suicide missions. One thing the movie did was show the terrorists having a fake bomb strapped to one of them that they were threatening to blow up. To fight back under these circumstances, not knowing whether that bomb was real or not shows incredible bravery. They also showed the passengers not realizing for a while that the pilots had been killed and weren't flying the plane. I don't know if that's what really happened -- not knowing whether the terrorists themselves were flying the plane -- but it certainly seems plausible.
But one particular part stood out for me, partially because it reminded me of a vaguely similar scene from another movie dealing with Islamic terrorism: The Siege. (If you haven't seen that movie, there are spoilers ahead.) In United 93, before the passengers charge the terrorists, you see several of them saying the Lord's Prayer, over the phone or just to themselves. They prayed for God to deliver them from evil and for him to forgive them as they forgive those who have sinned against them. Then the film cuts to the terrorists praying Islamic prayers and reciting the Shahada: "there is no God but God, Muhammad is the messenger of God." They recite this while they literally have blood on their hands, and are surrounded by the bodies of the people they murdered. The contrast could not be more stark. I'm amazed that a Hollywood movie was made which so clearly showed this contrast.
The similar scene from The Siege happened towards the end. (Remember: spoilers coming.) In the movie, there were a spate of terrorist incidents throughout New York City (this came out a few years before 9/11). They put all the Muslims into detention camps until they could figure out which ones were the terrorists and which ones weren't. Annette Bening is a CIA agent who has been working in the Islamic world for years, and is now protecting one of her informers. I think she reveals at some point that she is a lapsed Christian. In the end she gets shot by an Islamic terrorist. As she's dying, Denzel Washington starts reciting the Lord's Prayer with her. As Annette Bening finishes the Lord's Prayer, she concludes by saying "Insha'Allah" which means "God willing," and dies.
You might think this is no big deal. Christians often say "God willing" too. But it doesn't mean the same thing in Islam as it does in Christianity. Christian theologies almost always allow for there to be events which God does not will or even want, but which he allows. However, if God allows it, then he has a reason for doing so. Even the most evil events are not brute irredeemable horrors, God uses them to weave together the whole story of creation and salvation. As C.S. Lewis puts it in The Problem of Pain, "A merciful man aims at his neighbour's good and so does 'God's will', consciously co-operating with 'the simple good'. A cruel man oppresses his neighbour, and so does simple evil. But in doing such evil, he is used by God, without his own knowledge or consent, to produce the complex good -- so that the first man serves God as a son, and the second as a tool. For you will certainly carry out God's purpose, however you act, but it makes a difference to you whether you serve like Judas or like John." So even evil events play a role in establishing God's ultimate plan. God creates a universe in which every event plays a role in bringing about this plan. Thus, saying "God willing" in the Christian context means something closer to "If what I'm planning is something that could play a role in achieving God's ultimate plan."
In Islam, however, "God willing" is an affirmation of theological fatalism. It expresses the view that God is the only cause of everything that happens; that nothing happens unless God actively wills that it take place. While there may be some Christian groups who advocate something along these lines, the Hyper-Calvinists perhaps, it is almost universal within Christian theology to distinguish between events that God wills and events he merely allows. The second category can then be further divided up into events that God allows and wants, and events that God allows but doesn't want (and I guess a third class of events that God allows but that he doesn't feel strongly about either way). In contrast, Islam has only one category: events that God wills.
This difference between Christianity and Islam comes to a head when we look at their disparate views on salvation. As Jens Christensen writes in Mission to Islam and Beyond, "The whole content of the Gospel is simply this one thing: to show mankind that God is faithful towards His creation. He has restricted Himself with pacts, covenants and promises; . . . The 'if' in Christianity is always predicated of man: if you will believe, if you will trust, if you will accept, then God is faithful, you can always count on Him." So to ask God to forgive and save us if he wills to do so is just nonsensical. God has already promised that he will forgive us as long as we genuinely repent and have genuine faith. If we ask God to forgive us and then tack on a "God willing" at the end, it's saying if the God who doesn't change his mind doesn't change his mind, if the trustworthy God is trustworthy, then . . . . Putting an "if" in front of those statements makes them incoherent.
But Annette Bening's character does precisely that: she prays the Lord's prayer, asking God to deliver her from evil and forgive her for her sins, and then adds "if God wills it." God may forgive her, but he may not, and there's nothing we can say one way or the other. As Christensen points out, whereas in Christianity the "if" is predicated of us -- if we trust God, if we accept him, etc. -- in Islam the "if" is predicated of God -- if God chooses to save us, if God chooses to send us to heaven or hell. For Bening's character to say "if God wills it" after asking him to forgive her and deliver her from evil is to express the theological fatalism of Islam. It's to say that she doesn't trust God, doesn't believe him to be the kind of God who wants to save her, who loves her so much that he was incarnated as a human being to die to obtain her salvation.
Now this strikes me as a deep point, so maybe I'm giving the filmmakers too much credit to suggest that, like United 93, they were trying to contrast the hopefulness and peace that Christianity offers with the hopelessness and chaos that Islam offers. If they were, though, then again I'm amazed that a Hollywood movie was made that so clearly showed this contrast.

The original Brexit
Since I noted Canada's 150th anniversary a few days ago, I can't fail to wish everyone a happy Independence Day. 241 years. It's a little disturbing because I have some childhood memories of our bicentennial. There's people still alive who should remember our sesquicentennial.

How to become an astronaut
Lots of kids want to be astronauts when they grow up. My generation got screwed in that regard. We went from Kitty Hawk to Mare Tranquillitatis in 66 years. Then, after a few more trips, we stopped going to the Moon and just went into low earth orbit over and over again. (This made no sense: as Heinlein, I think, said, once you reach low earth orbit, you're halfway to anywhere in the solar system in terms of energy expenditure.)
Well, things might be changing: the President just revived the National Space Council and the House Armed Service Committee just voted to split the Air Force in half, with one half becoming the U.S. Space Corps. This reminded me of a conversation I had with my son several weeks ago when he asked me how to become an astronaut. I told him I have no idea what actual private or government organizations that are pursuing space exploration will look for, but I know what I'd look for in a potential astronaut. Specifically, I told him two things I'd look for. They're not completely separate; in many cases if you get one you'd also get the other.
First, I'd want someone with experience in living and working long-term in a small, remote community. This could be an isolated military base or just an isolated science station or village. By "isolated" I don't mean that the person spent time alone. What I'd look for is someone who spent an extended period of time in a small community which did not have any other people nearby. Part of the goal here is to show that you could live with a small number of other people (thus being by yourself in an isolated area wouldn't help) without any nearby support for an extended period of time. Obviously, if we set up a station on the Moon or Mars or an asteroid or wherever, any people there would be cut off from the rest of human civilization in significant ways, and the closest case to that now is people living in small remote communities.
Second, I'd want someone with experience living long-term in confined quarters. A submariner would be perfect. Submarines are designed to minimize the open space inside, which means that claustrophobes need not apply. Spaceships transporting people to wherever would similarly require a minimal amount of open space inside. And if we establish manned stations somewhere, they probably would have to be designed along similar lines. It would be nice to have an extensive station with plenty of open space, but it might not be feasible. And note that someone with experience living in confined quarters with others will very probably also have experience living in an isolated community. The crew of a submarine has experience with both automatically. Someone living in a village or station with an extreme climate (like Antarctic research stations, or villages in Qaasuitsup Greenland) would also spend a great deal of time indoors, which would be moderately similar.
Again, this is what I'd look for in a potential astronaut, not what the actual people actually recruiting actual astronauts will be looking for. It makes sense though.
