Space Saturday XXXVI: The Rosette Nebula

February 26th, 2011 No comments

The 36th edition of Space Saturday brings us the Rosette Nebula.

The Rosette Nebula

The Rosette Nebula (Click for larger version.)

This beautiful image of the Rosette Nebula comes to us from Brian Lula (source) and is found in theconstellation Monoceros. Nebula is about 5300 light years away and contains hot, young X-ray emitting stars at its center.

Inside the nebula lies an open cluster of bright young stars designated NGC 2244. These stars formed about four million years ago from the nebular material and their stellar winds are clearing a hole in the nebula’s center, insulated by a layer of dust and hot gas. Ultraviolet light from the hot cluster stars causes the surrounding nebula to glow.

Storm Front: The Dresden Files by Jim Butcher

Storm Front: The Dresden Files by Jim Butcher

Storm Front: The Dresden Files by Jim Butcher

On another recommendation from Dan I picked up the first of The Dresden Files series: Storm Front. It was another enjoyable entrance into the realm of fantasy. Here we meet Harry Blackstone Copperfield Dresden a private detective trying to pay his rent and make it from day to day in our difficult world who also happens to be a Wizard.

What’s a guy to do when the White Council is out to get you, when the cops lose their faith in you, when people are being murdered by magic and some want to blame you? Well, I guess you take matters into your own hands and do your job, even if that means venturing into the dark.

Odds seemed really good that I was going to get killed, whether I tried to face him or not. To hell with it, then. If I was going to go out, it wasn’t going to be while I was lying around moaning and bitching about how useless it all was. If Victor Sells wanted to take out Harry Blackstone Copperfield Dresden, he was going to have to shove his magic right down my throat.

He was having a rough day, but he sure kept on going! And without giving too much away, I had to quote this toward the end of the book:

And so, I walked through a spectral landscape littered with skulls, into the teeth of the coming story, to a house covered in malevolent power, throbbing with savage and feral mystic strength. I walked forward to face a murderous opponent who had all the advantages, and who stood prepared and willing to kill me from where he stood within the heart of his own destructive power, while I was armed with nothing more than my own skill and wit and experience.

Do I have a great job or what?

Doesn’t that just make you want to check this book out? Well, you should!

The Prodigal God by Timothy Keller

The Prodigal God: Recovering the Heart of the Christian Faith by Timothy Keller

The Prodigal God: Recovering the Heart of the Christian Faith by Timothy Keller

I started reading The Prodigal God: Recovering the Heart of the Christian Faith by Timothy Keller right when I got my Kindle, blazed through most of this amazing book, and then promptly got distracted by a few other books… Well, I finally finished! Keller’s thesis is summarized neatly:

Jesus’ great Parable of the Prodigal Son retells the story of the entire Bible and the story of the human race. Within the story, Jesus teaches that the two most common ways to live [the younger son's estrangement from the father and the elder son's self-righteousness before the father] are both spiritual dead ends. He shows how the plotlines of our lives can only find a resolution, a happy ending, in him, in his person and work.

This is a very quotable and profound book, I hope you will read on (Sorry, it’s going to be a long one!)!

Keller does a wonderful job of exegeting the parable from Luke; while there were similarities with Nouwen’s Return of the Prodigal Son, Keller’s take is more theological to Nouwen’s more reflective spiritual journey. That being said, don’t let “more theological” dissuade you from delving into this book; it is a worthy read for a long time Christian (even necessary I would say, we tend to be Elder Brothers), a new Christian trying to find a home in the faith, or someone who is seeking the faith but been put off by the Church. We all, and I do mean all, find ourselves, at different points in our lives, as either the estranged younger brother or the strictly moral older brother, both of which we find unsatisfactory.

Jesus uses the younger and elder brothers to portray the two basic ways people try to find happiness and fulfillment: the way of moral conformity and the way of self-discovery. Each act as a lens coloring how you see all of life, or as a paradigm shaping your understanding of everything. Each is a way of finding personal significance and worth, of addressing the ills of the world, and of determining right from wrong.

But, as I’m sure you are fully aware, they both fall short. What we need is the Father. Here is the crux of the situation:

Neither son loved the father for himself. They both were using the father for their own self-centered ends rather than loving, enjoying, and serving him for his own sake. This means that you can rebel against God and be alienated from him either by breaking his rules or by keeping all of them diligently.

Bummer! Fortunately the Father invites both sons back into his home and the feast that awaits.

The gospel is distinct from the other two approaches: In its view, everyone is wrong, everyone is loved, and everyone is called to recognize this and change.

Amen and amen. After being asked what is wrong with the world, G. K. Chesterton replied, “I am.” Keller notes, “That is the attitude of someone who has grasped the message of Jesus.”

We deserve alienation, isolation, and rejection. The point of the parable is that forgiveness always involves a price – someone has to pay. There was no way for the younger brother to return to the family unless the older brother bore the cost himself. Our true elder brother paid our debt, on the cross, in our place.

The elder brother in the parable was self-righteous and angry that his father could allow the younger brother to return, it had a literal cost to the elder brother. Thankfully our true elder brother in Jesus was willing to pay for our return to the Family. John Newton is quoted from one of his hymns:

Our pleasure and our duty,
though opposite before,
since we have seen his beauty
are joined to part no more.

A wonderful summary of the work of Christ I would say. This is the Gospel. We are broken and redeemed freely by grace. We were (are?) the estranged younger brother but that doesn’t mean we have to become the self-righteous elder brother. Our Father is inviting us in to the party, his eternal feast. We should accept.

Hearing the word “prodigal” applied to God seems odd to us because we usually think of the “prodigal son” which usually has the connotation of someone who has screwed up. This is a misunderstanding of the word “prodigal”. Prodigal means to spend money or resources freely and recklessly; to be wastefully extravagant. As Cori puts it in her review, “the reader learns that God is recklessly extravagant with us. He’s spent everything on us. He is truly a prodigal God. I found this concept to be achingly beautiful.” Indeed.

Keller leaves us with this passage out of Isaiah and so will I:

On this mountain the Lord of hosts will make for all peoples
a feast of rich food, a feast of well-aged wine,
of rich food full of marrow, of aged wine well refined.

And he will swallow up on this mountain
the covering that is cast over all peoples,
the veil that is spread over all nations.
He will swallow up death forever;

And the Lord God will wipe away tears from all faces,
and the reproach of his people he will take away from all the earth,
for the Lord has spoken.

The Color of Magic: Discworld by Terry Pratchett

The Color of Magic

The Color of Magic - A Discworld Novel by Terry Pratchett

I have never been much of a fiction reader, but I am always willing to take suggestions from people. Especially when I generally appreciate their taste in literature. Dan likes to read good sci-fi and/or fantasy so when he suggested I read Terry Pratchett’s Discworld I thought I would check it out. The first in the series (why is it I always get myself into a series with more books to buy!?), The Color of Magic, was quite an enjoyable entrance into the Discworld universe.

It was whimsical and fun with endearing characters. While Rincewind and the tourist Twoflower went on their adventures, I quite enjoyed his luggage popping up from time to time to add to the levity and excitement.

If you are looking for a well written fantasy book or series, The Color of Magic: A Discworld Novel would be a good place to start.

Discworld with Great A'Tuin

Discworld with Great A’Tuin

And since Pratchett has written quite a few Discworld novels, someones has even created a very helpful chart: The Discworld Reading Order Guide.

Also, since the geography is somewhat confusing, which is bound to happen when your planet is a flat disc on the back for four elephants which are, in turn, standing on the back of Great A’Tuin, a giant tortoise, there are a number of maps available.

Recommended? Absolutely.

Hunger Games by Suzanne Collins

Hunger Games by Suzanne Collins

Hunger Games by Suzanne Collins

Last time I decided to read what all my students were reading I ended up going through the Twilight saga. While I feel they weren’t entirely bad (don’t judge me!), they weren’t quite the substantive read I would hope my students would choose (although reading something is better than nothing I suppose). I noticed recently that there were quite a number reading Hunger Games by Suzanne Collins (as well as the sequels) so figured I would see why there was all the interest. The synopsis seemed engaging enough and Cori even recommended it, so why not delve back into another series that my students are obsessed with.

I was very pleasantly surprised by both the plot and the characters. The story was quite intense (that’s what happens when kids are battling to the death…) and dealt with a number of difficult issues: strength, loneliness, independence, friendship, oppression, violence, murder, sacrifice, and politics (among others). The first person narrative gives insight into the mind of a 16 year old girl, Katniss Everdeen, who is trying to survive (in a number of ways) in a death match. Her thought process is well written (contrary to the almost inane inner workings of Bella) and insightful.

As Cori mentions, it would be nice to see more discussion or development of the issues of children killing other children and the torment that must go along with that. They are being forced into these violent situations and that must change them at the core. I imagine that the sequels will have to deal with this in some way; they couldn’t stay the same after their ordeal.

The scene that impacted me the most (spoiler ahead) was not the death of Katniss’ new found ally, Rue, but shortly thereafter. It was only so meaningful to me because of how the relationship between Katniss and Rue was developed. I quote it here (yes, it made me cry, but out of context, it probably won’t be as meaningful to you…):

I’ve no idea where to go. The brief sense of home I had that one night with Rue has vanished. My feet wander this way and that until sunset. I’m not afraid, not even watchful. Which makes me an easy target. Except I’d kill anyone I met on sight. My hatred of the Capitol has not lessened my hatred of my competitors in the least. Especially the Careers. They, at least, can be made to pay for Rue’s death. [...]

I’m about to haul my packs into a tree to make camp when a silver parachute floats down and lands in front of me. A gift from a sponsor. But why now? I’ve been in fairly good shape with supplies. Maybe Haymitch’s noticed my despondency and is trying to cheer me up a bit. Or could it be something to help my ear?

I open the parachute and find a small loaf of bread. It’s not the fine white Capital stuff. It’s made of dark ration grain and shaped in a crescent. Sprinkled with seeds. I flashback to Peeta’s lesson on the various district breads in the Training Center. This bread came from District 11. I cautiously lift the still warm loaf. What must it have cost the people of DIstrict 11 who can’t even feed themselves? How many would’ve had to do without to scrape up a coin to put in the collection for this one loaf? It had been meant for Rue, surely. But instead of pulling the gift when she died, they’d authorized Haymitch to give it to me. As a thank-you? Or because, like me, they don’t like to let debts go unpaid? For whatever reason, this is a first. A district gift to a tribute who’s not your own.

I lift my face and step into the last falling rays of sunlight. “My thanks to the people of District Eleven,” I say. I want them to know I know where it came from. That the full value of their gift has been recognized.

I know that was lengthly, but I feel speaks volumes.

The book is a fairly easy read, it is, after all, “Young Adult,” but is also quite enjoyable with a variety of relatively deep themes. It’s worth checking out. Now, on to book two: Catching Fire!

Stephen Krashen and Comprehensible Input

February 4th, 2011 No comments

We must give people messages they understand. We acquire knowledge when we understand what people tell us not how it is said. Watch this video clip (from the 80s??):

In the clip Krashen clearly demonstrates that in order for someone to understand what they hear – the comprehensible input – the message needs to be clear. And by clear I don’t mean enunciated well, I mean relatable and meaningful to the learner.

Language acquisition, really, knowledge acquisition in general, is difficult. Clearly the model has been that of Krashen’s first lesson in the clip. We (educators) spout knowledge. We assume that knowledge is just assimilated by the students doing the learning. But unless we shift to a lesson two mentality, the chances that all the students are acquiring the knowledge we intend is very small.
