Clunker Dilemma

Back when our "new" car reached the age of 10, we considered buying something more up-to-date. But then the economy tanked and we postponed. I also am holding a rarely used "old" car that is 17 years old. It qualifies under the new Clunker Bill, wherein it is worth $4500 in trade in. I've put about $4,000 into it and driven it nearly 1,000 miles since I bought it for 2 grand in 2005. Not a very good deal. But it is only worth about $2,000 according to Kelly Blue Book. We obviously don't really need a second car, but it does seem like a good time to buy. So, do I save money by selling the old car off for maybe $1,500 and cut my losses? Or should I invest in a new "new" car that qualifies for the trade-in and relabel our "new" car as the spare?

Anniversary of a New Land

Today marks the 40th anniversary of "...one giant leap for mankind." On July 20, 1969 a human first stepped onto the moon. Oddly, there is a significant minority of people who don't believe this. The Moon Landing Deniers (on whom I reported here 3 years ago) now have to increase the complexity of that conspiracy theory because of some recent news. Here are some new pictures taken from lunar orbit in the last few weeks of some of the Apollo landing sites. The point of the Lunar Reconnaissance Orbiter wasn't to prove the doubters wrong, but rather to gather an accurate survey of the moon to aid the Chinese (and maybe ourselves) in future exploration. You may recall that Apollo 11 almost crash landed on a rock pile, and Armstrong had to manually hover the lander over to a smooth area, landing with scant seconds of fuel to spare. They don't want to repeat that experience. Also, the orbiter should map out interesting mineral and erosion features that merit closer investigation. As one who watched the first landing live, I like to think that we'll be back.

Civilian Rocket Helps to Fill the Gap

As you may know, NASA's 1970's technology Space Shuttle is about to retire, and NASA hopes to have a replacement system after a gap of a few years. Good planning, guys! Sure, the U.S. has plans to hire French and Japanese and possibly even Chinese technology until we can catch up in space. Enter SpaceX spacex logo This completely private, completely civilian company has just launched a satellite, and has paying customers queued up for future launches. Including NASA. Kudos to PayPal founder Elon Musk for going from start-up to commercial flights in just 7 years.

Repercussions of Kevin Bacon

I was watching the one hour documentary "How Kevin Bacon Cured Cancer" and thought I'd share a few thoughts. Presumably anyone reading this already knows the principle of "Six Degrees of Separation" and the game involving this actor. My thoughts have nothing to do with the actor, but rather with the field of study that actually emerged from this Urban Myth: Network Theory. One thing that jumped out at me was that network theory appears to neatly show how organization and information growth are necessary results of random connections. In other words, organization Just Happens. This has always been observed. It was historically explained as either the result of very, very sophisticated design, or a "goal" of evolution. But now there is a mathematical model showing that systems become organized because of entropy, not in spite of it. Unfortunately, those who doubt evolution usually never get far enough in math to see this. Another thought I had was in response to the observation that a network becomes efficient given many points (or nodes) with few and local connections, plus a few nodes with many and far-ranging connections. These widely connected nodes are the key to the usual success of the game of six degrees, or the stability of the internet, or the synchrony of crickets, or the efficiency of our nervous system, or any other network. I asked myself, "Given a choice, would I want to be a social node of local, or widespread connections?" I'm not particularly interested in how useful I may be as a connection in a game of Six Degrees, but rather how much fuller is ones life given wider connections. More points of view lead to understanding more ideas. I talk to people in all lines of work, of any political or religious affiliation. I converse to listen. Ideas that conflict with what I "know" are interesting to investigate. (At least until I understand why they conflict, and then they are inflicted repeatedly by those who don't understand the conflict.) Although I am a social stick-in-the-mud, I've met relatives who live on 4 continents, and have visited yet another. I gravitate toward people who also collect people. This blog (for example) has authors from several continents. I have also traveled to a few places, many shown on this "Cities I've Visited" vanity map:

And I am always asking questions, and making connections. I enjoyed the TV series, too.

What’s in a Type?

One of my peeves against anti-evolutionists is those moderates who fully accept gene drift and mutations for short term changes (breeds, "micro-evolution") but not longer term changes (species, types, "macro-evolution"). Try to pin one of those people down on a definition of species and type, and one can always show them an observed example of something that crossed the line, or else multiple species that are obviously different but on the same side of their line. But this post is broader than that. For example, Pluto was a planet. Everyone knew that. Recently it was demoted to dwarf-planet. There are groups still dedicated to its reinstatement as a planet, like the Society for the Preservation of Pluto as a Planet. My presumption is, because that's what they were taught in their youth, therefore it's "As God Intended". Nothing changed in the sky, nor in our understanding of how things work. But a category changed and our world shook. Well, at least the world of those of us who noticed. What of moons? An excellent article is here: Meet our Second Moon! We now have two moons? And in my lifetime, the origin of our main moon changed from an unlikely captured or even less likely co-congealed object to a reasonable and most probably ejected one. I remember being disturbed when the moon count around Jupiter went from 12 (the 19th century standard) to 63 (care of Voyager etc). The count varies depending on how you define "moon". One has to be broadly accepting of both size and ballistic classification to accept 3753 Cruithne as a moon of the Earth, but it is there. Speaking of the moon, here is an incredible new way to see our moon up close (with pan and zoom) taken from ground based cameras. Things change. As I have mentioned many times on this blog, most people are hung up on the misconception that words accurately define things. The thinking that, if you have a name for it, then you understand the thing. You get the collector's fallacy: The confusion of the joy of matching names to things with the understanding of the things themselves. Knowing the names of thousands of birds (or bugs or species or stamps or diseases) and accurately matching them to the subjects is useful. But it is not complete in terms of understanding the similarities and differences. That is what is meant by the quote "Biology without evolution is but stamp collecting". One cannot understand things without also understanding the relationship between things (species, astronomical objects, populations, etc) and knowing the latest (most complete, so far) underlying set of theories (scientific definition, not vernacular). Humans are better than most other creatures at recognizing patterns. We regularly see patterns in random observations: Pareidolia. Any set of words will be an incomplete definition of any object. Defining a class of things is even more nebulous. Do species change over time? Certainly, given either enough time or a precise enough definition. How many moons are in the solar system? Good question. Define "moon", and show me the latest ballistic data on the 100,000 largest object so far discovered inside of the Oort Cloud. By the time I have an answer, something will have changed.
