Things that are true

"Axial tilt is the reason for the season." (Picture a globe with the northern hemisphere tilted away from the sun...) I believe this is meant to be an anti-theist slogan, although I would point out that I believe there is a reason for the axial tilt.

This is a runner up to my favorite true science picture, the "Gravity Forecast." I linked to this when I was a graduate student, but the site is long since down. Picture a weather forecast graphic, but instead of clouds and temperatures, the 5-day forecast predicts 9.8 m/s^2 down. Even the idea still makes me laugh, perhaps I will reproduce it someday.

Luke cut his 4th tooth today (Finally!). So far they haven't caused us too much trouble. We'll see what happens when he gets his canines.

I don't think it's meant to be an "anti-theist slogan" -- I think it's a joke. Apparently Fox News thinks there's a "War on Christmas" or something and the atheist blogs are making light of this dreadfully serious concern. ;^)

So what's the reason for the axial tilt? I'll admit I don't know much astronomy/astrophysics.

By coincidence, just the other day a friend of ours was telling us about how much fun it is to look at the NASA website because apparently they update their space photos regularly. We were wondering about what causes some planets to have rings and others not. Emmanuel said it had to do with what materials were present when the planet was forming, but it's still kind of amazing that it would form a plane like that. And so with rotating on a tilted axis -- I'm not sure why that happens. Of course it probably has a straight-forward explanation -- I could always read a book on it or something. ;^)

Hi Chanson!

I'm glad it's just a joke. It is making fun of Christians (not theists, as I posted...) but we can handle it =). I guess I saw it only on atheist websites, so I assumed something that wasn't true. I personally think it's hilarious.

I was referring to divine providence as the ultimate reason =) but there is probably a scientific reason as well, since the tilts of different planets are different. I have heard that without axial tilt (or with a greater tilt), life on earth would be much more difficult, but I am starting to think that the people who told me that had other motives.

I do not believe there is a "war on Christmas", however at my daughter's school they are talking about Diwali, Hannukah, the Winter Solstice, and Ramadan. No one is talking about Christmas, or even St. Nicholas's Day. My feelings on this probably require a post of their own. Suffice it to say that on the one hand I feel ok about this omission because it's great for Eleanor to be exposed to other beliefs and we do a better job with religious education than the school would. On the other hand, it's a bit strange, since the story of the first Christmas isn't covered in the media any more than the story of Hannukah or Ramadan is, and 5 year olds should know it.

...I was referring to divine providence as the ultimate reason =) but there is probably a scientific reason as well...

1: As a christian theist trained in science, I have come to the conclusion that this is not a useful distinction. Consider this oversimplied sequence.

Given, that 'god' == whatever formed the cosmos (including the possibility that the cosmos formed itself).

Given, that the cosmos exists.

Then, 'god' exists. (Stay with me here...)

And, all 'natural' processes are therefore also 'providential'.

And therefore it does not matter, for the purposes of explanation, whether 'god' had an intent (providence) that was/is conceptually distinct from the outcome (nature).

2: Corollary - Whether or not 'god' is distinct from the cosmos, we therefore don't have the option of deciding whether 'god' exists, we only have the option of trying to discern whether 'god' is in some sense an individual, whether (as theistic religions claim) humans are morally accountable to 'god', and whether (as christians claim) 'god' was personified in the man Yeshuah of Natzaret, who allegedly satisfied the moral claims of 'god' against 'man' by being crucified and raised again.

(This also may be viewed as 'providential' or 'natural' depending on how complexly one wishes to understand 'nature'. I would argue that everything perceptible, including moral sensibility and spirituality, since they exist, are part of 'nature' and thus the distinction between 'spiritual' and 'natural' is an artificial one, used chiefly to create a dualism that may or may not be realistic.)

end of musings. I am thankful for moderation, as I don't want this to sound like a rant, and I'm confident that Kim will let this through only if it seems actually interesting and not troublesome.

Hi Dan!

I agree that if you believe in God, separating out nature from divine providence is not useful. However, if you want to know (for example) why there are rings around Saturn, saying "divine providence" is not really very interesting for anyone.

I am starting to come to the conclusion that I need another blog to talk about issues, as opposed to family stories. (I do admit that I brought it up in this case =) Unfortunately I have barely time to write and edit this blog. Maybe after Christmas I'll have some more free time (Ha!) and will start my new blog, "Yelling at the radio." Then we can talk about the existence of God, politics and religion and education, my comparison of dental work and catholic confession and so on.

I don't think that's true. Just tonight I put on The Year Without a Santa Claus for my kids, and when it was done, they chose to put on Nestor the Donkey, which tells the nativity story and was on the same disc. That one is not as popular as some of the Rankin-Bass specials (since it's not as well done), but for an example of a very popular story, there's The Best Christmas Pageant Ever, which is quite charming and made into a fairly popular movie/special (which tells the nativity story as a story within a story). That story was a tradition at my house growing up, and I wouldn't object to my kids watching it. For more modern stuff, I imagine Veggie Tales covers it, and that's just what strikes me off the top of my head -- there are probably more. But the story of Ramadan, Hanukkah, or Solstice in a pop-culture children's program? I've never seen a single example.

Sigh. You are probably right about the nativity story in popular culture, although I'm not quite ready to cede the point. Nestor the Donkey is being shown at 10:30 at night, and even the Charlie Brown Christmas show has been relegated to the back burner, whether because it is boring to modern audiences or specifically because of its religious content, I don't know.

However, almost all of the secularized traditions that they are talking about in class definitely are related to the religious festival, although they were mostly co-opted from other festivals before that. And the traditions, rather than the theology, were most of what was covered with the other festivals.

In conclusion, I should just not complain. Perhaps we should just all celebrate Saturnaila together, instead of a mostly secular holiday which happens to be called Christmas. =)

(I did start another blog, and my first post was going to be about this issue, but it crashed my computer. Perhaps this is a sign. =)

Hi Dan---

I was mostly suggesting Saturnalia because our high school Latin classes made a big deal of it, and they seemed to promote the idea that it was a good time. That was an interesting ritual you pointed to, I don't think the Latin class got into that =).

My hero, Helen Parr

Otherwise known as Elastigirl , a.k.a Mrs. Incredible. She is a stay at home mom ( SAHM ), she clearly feels that what she is doing is important and is willing to give up a lot to do it (remember her comment in the intro: "I'm at the top of my game! Leave saving the world to the guys? I don't think so.") But she is finding fulfillment in leading her family from day to day, in doing a hard job well. She also knows that she is very talented, and that knowledge helps her see beyond the repetitive drudgery of staying home. My favorite scene is from the deleted introduction, where she talks with a "career woman" who is of the opinion that staying home is fine for people who can't do anything else. She responds that taking care of her kid is at least as hard as saving the world, and is valuable contribution to society. The point for me is that someone has to do the job that I'm doing, and it's not something that you could pay someone to do. I see...

Kindergarten Fashions

I was informed the other day that Eleanor wants to get a new thermos. She lost the o-ring from her purple Tinkerbell thermos, and I have so far resisted buying another one for her, on the theory that you shouldn't just replace things that are broken since it doesn't encourage being careful with one's things. I have been sending her with the sippee cups that she has been using since she was a year old, which she has resisted giving up to the point of becoming partly dehydrated when I don't let her use them at home. Here's how the conversation went. Eleanor: Anna and Jane said today at lunch, " Kindergartners don't drink from sippee cups!" Me: That's very interesting. Eleanor: They are supposed to drink from thermoses. Me: Eleanor, would you like a new thermos? Eleanor: Yes! Get the purple one, please. If there is a crayon one, that's the one I want.... Who knew that peer pressure started in kindergarten? The sippee cups are perfectly f...

Girl toys

A friend just had a post about her son's desire to have a pink bejewled play phone (she and the people who comment have great things to say: here it is so you can read it). Thinking about her post made me very glad that for girls 5 and under (which is all I have experienced lately) there is no toy that is off limits as far as I can tell. Amanda's favorite toys are trains (although she doesn't play with them the way some of her boy friends do. I think Chanson's kids would play well with her version of trains). Her favorite movie is Cars. Her favorite TV show is Bob the Builder. No one in her life (relatives, friends, teachers) tells her that she can't enjoy all of these things. On the other hand, she likes to play with all these things while she is dressed as a princess... In Eleanor's class, everyone's favorite thing to do is woodworking, both girls and boys. The only mathematicians she knows are women, so she expects to do well in math as well...
