Shift


Evolution before our eyes. It's amazing that though concepts like evolution, relativity, and quantum physics are in all of our mind - established parts of science - but we've been studying them such a short time that big discoveries are still very possible. There may even be more big discoveries in front of us than are behind us, so young are our studies of some subjects.

A case of evolution observed.

We've only been "enlightened" so long, and the world is growing and becoming more fascinating before our eyes. I was driving a few days ago and thought about how we now have paved roads that connect the upper reaches of canada with their antarctic counterpart in Argentina and yet 100 years ago, in 1908, cars were still propped up on wagon wheels. Every facet of our universe is touched by this. We move from a view based on tradition to a view based on discovery and learning, and expanding. Our definitions have changed, anthropologists even have a difficult time defining what exactly sets us apart as "humans." It used to be activity, like tool making, but gorillas were found to do that, even birds and insects have been found to do that. We're so much a part of this world and we are so lucky to be living in a time where we're beginning, at such an accelerated rate, to see what we are, and what this universe is.

Gracious

I haven't posted in a while. These cruel dipthorians mount the raging rays.

Here's a short, 15 min clip of a physicist talking about what's going to be happening in the LHC (the Large Hadron Collider), where we'll hopefully be able to see what was happening billionths of a second after our universe began. Very cool stuff.

Arbitrary Gestures

Today's Adventures:

Hair cut - Same as always, but my dyed, then bleached hair looked very strange as it was getting swept up off the floor. Like the mane of a baby lion.

Change Cell Phone plan - The year was up, I went in, got unlimited texting, and got me a chocolate. It's definitely the coolest phone I've ever had, and the one with the most appetizing name (way better than VX6895, blegh).

Shopping - Needed a few things. Dishwasher detergent, paper towels, cat food. What a difference some Jet Dry in the dishwasher makes, too. Oh and I picked up I Am America and So Can You as a book on CD, so that'll be good to keep the trend after Death in the Afternoon.

Writing - Dear readers, I stumbled in my pursuit. Friday I consciously decided to "take a day off," and then last night I just planned poorly and was too tired when I got home to really get out anything good. Both of these were mistakes. So today I'm doing a 3000 word marathon. I'm about half way thru and I like the results so far.

Discovery - Adventure Alaska or Alaska week or something starts at 9 on the Discovery channel and I love Alaska and want to watch it, so we'll see if I can't get the writing done before then.

Birds - April showers bring floods, and what do floods do? Kill birds. To help combat that, I've refilled the bird feeder I hung outside my window last spring. The Professor is enjoying crackelingly meowing at the patrons.

Tomorrow - Grind grind grind the pieces of my soul away. My first of five flights is on Thursday. I'm anxious to get out of that place.

Cheerio.

Discovery.com

The world is just awesome.

I love how the discovery channel has really come into it's own in the last few years, or maybe I just didn't watch it much before that. It's my default channel whenever the TV turns on in my house.

An Interesting Bit of Biology

Females have 2 X chromosomes and males have an X and a Y, right?

Well, those X and Y chromosomes produce "gene products." All that means is that the gene codes for something, that is, it tells the cell it's in to makes something, usually a protein.

Since females have 2 X chromosomes that are identical, their cells go thru a process called lyonization. All it does it makes one of the X chromosomes in each cell inactive, otherwise it would produce twice as much of the gene products - twice as much as males.

In placental animals (most mammals), the X gene that is inactivated is random, it can either be the one the father or the mother contributed. However, in marsupials, it's always the fraternal X chromosome.

I learned that while procrastinating in writing my paper for Biology.

Man, that guy on Man Vs. Wild is such a freakin MAN! It's like all the crap I did at survival school, just way more badass.

I need to get those DVDs.

Backlash

I wrote a response to Randy's statements, but I won't frighten the rest of you with it here, or it's length. I'm posting it in the comments of this entry, if you'd like to read it.

Bear With Me

Okay this is long and pretty out of place in the "comments" section. But it's still a response to the comments in the post previous this:

I know this discussion feels like beating a dead horse, but there's a true disagreement between us, isn't there? So either I'm just not getting something or you're not getting something, or maybe we're both not getting something. But conversation is the best way to sort this out, where we're both able to give our sides in hopes of establishing our position as true. Because only one of our sides can be true, and learning truth is very important isn't it? So allowme, please, to beat this dead horse a little longer (longer with big red).

Regarding the issue of "falling in love." I agree with you that "falling in love" with another person may be a perfectly understandable, legitimate act. Science is still in the process of understanding the mind, but maybe there really is, say, a pattern of chemicals in our own brain that somehow matches with the other persons or something like that, something that's very real and can catalogue this emotional act we call, "falling in love." When you extend this to the spiritual realm, there's a couple problems though. The first I see is this: when was the last time you heard a chemist say, "You need to respect my beliefs about chemistry. They were revealed to me through something like falling in love." Or a doctor say, "Please respect my beliefs about how I practice medicine. They aren't verified by experiment, but if you'd gone thru what I've gone thru, you'd see what I mean." We don't respect conclusions people come to just by sitting in their own mind, we evaluate reasons.

The second problem I see springboards off this: These "spiritual," if I may lump them into that category, experiences may be useful in describing the human experience - how we observe the world - but they are not useful in explaining the true nature of the world, if not coupled with empirical evidence. Our sensory perception is fallible, and our emotional perception is exponentially more fallible. Take a look at this for a demonstration on the fallibility of just our eyes. People have imaginary friends that they think are to more or less a degree real, depending on their particular mental state - but make no mistake, many people's mental and emotional experience is just as authentic as your "falling in love," yet it's toward Allah or Sathya Sai Baba. Let me here quote Sam Harris again (in speaking about spiritual experiences): "What atheists don’t tend to do is make unjustified (and unjustifiable) claims about the nature of reality on the basis of such experiences. There is no question that some Christians have transformed their lives for the better by reading the Bible and praying to Jesus. What does this prove? It proves that certain disciplines of attention and codes of conduct can have a profound effect upon the human mind. Do the positive experiences of Christians suggest that Jesus is the sole savior of humanity? Not even remotely — because Hindus, Buddhists, Muslims and even atheists regularly have similar experiences.

There is, in fact, not a Christian on this Earth who can be certain that Jesus even wore a beard, much less that he was born of a virgin or rose from the dead. These are just not the sort of claims that spiritual experience can authenticate."

So just to reiterate what he's saying: yes those "falling in love" experiences are useful in telling us things about our own mind - but are not useful in telling us things about the world. So however great your reasons for falling in love are, and however big your emotions are - they are slightly more than useless in telling us whether a statement like "God exists" or "Jesus ascended bodily into heaven" are true.

And Julie, I apologize if I was unclear. My question wasn't "why would someone choose to seek out God." I think I understand that to some degree, as I did it myself for about 20 years. My question, instead was HOW is it possible to determine which God or "religion" is true, if you've forsaken reason in your "leap of faith." As long as we're defining leap of faith in the Kierkegaardian way as a deciding to believe something without empircal evidence that it's true. My question, really, is this: In looking at all these religions, as you did, when it comes down to it, you're looking at a set of propositions which, basically, are not convincing in their own right. All of these are religions that REQUIRE you to stop thinking about logic and reason, and just DECIDE that one of them is true, right? That's what I understand when someone says "faith comes first." Obviously they're not convincing from a logical point of view, or you wouldn't NEED faith to come first - it would be just as convincing as 2+2=4 or believing there's really a chair underneath you. So, if there is a road of logic that leads to a chasm. On the other side of the chasm you see Christianity, Buddhism, Islam, Jehovahs witnesses, and leading away from all of those is their own road of "logic (the logic of the Bible that God reveals to you AFTER your leap of faith)," how do you decide which one to jump to?, if you "logic" map likewise has a blank spot there?

I think it's also important to point out is the false dilemma I think people push themselves into during these encounters. As you said, "I became knowledgable on J.W., Mormons, evolution, Christianity and New Age." As though, if you found all but New Age to not make sense, you would default to New Age...or none of them make sense except evolution, so you default to evolution. We have to give ourselves the license to say "I don't know." There is so much confusion, I think, in people thinking that poking holes in evolution makes the doctrine of creationism and christianity on iota more likely. It doesn't. If evolution is false (which the evidence points heavily to it not being false, but that's not this argument), it is a perfectly respectable position for an atheist to simply be an atheist - not knowing how the life around us came to be. We need not believe ANYTHING on insufficient evidence. We would, in most cases do well to side with the position that is most likely - has the most evidence on its side - but if I, for some strange reason, had to say I'd die rather than say that the big bang theory may be overturned in the future, I'd plead ignorance rather than arrogance.

And just one more thing, Julie, regarding yours. I don't understand why you would, at the same time both attempt to undermine the foundation of science, in saying that it requires faith, while using science to try and legitimize the Bible. You've admonished me twice now on how much the bible and science have in common. In fact, right now, with the uncertainty principle in quantum theory as well as more "recent" discoveries like "action at a distance," if science bolsters any one faith system it's new age or eastern philosophy, hands down. You can point to some things in the Bible like the the water cycle in Job or the circulation of the atmosphere in Ecclesiasties, but when we come to parts like Leviticus 11:6 "And the hare, because he cheweth the cud, but divideth not the hoof; he is unclean unto you." (hares don't chew the cud) Or Job 9:6, "Which shaketh the earth out of her place, and the pillars thereof tremble." (the earth does not stand on pillars, though many ancient cultures said similar things) Or 1 Kings 7:23 - "He made the Sea of cast metal, circular in shape, measuring ten cubits from rim to rim and five cubits high. It took a line of thirty cubits to measure around it." (Notice anything wrong? In this verse, pi=3), people will say that many of these verses in the bible are "figurative" or "the bible isn't a science book" or that there was somehow a miracle that made the animals bred in front of the striped sticks turn out all stripey. This makes the argument very convenient - either it's science, or a miracle, and therefore everything, both benign and strange, in the Bible, is easily accounted for. I'd just like to point out that Harry Potter is a true story as well, as long as everything in it is science, a miracle, figurative language, or just "rounding off." You can choose a few a FEW verses in the bible that support science. This website catalogues some. Many of them literally made me laugh out loud in how far they're stretching. "Jeremiah 33:22 “As the host of heaven cannot be numbered, nor the sand of the sea measured, so will I multiply the descendants of David My servant and the Levites who minister to Me.” Yes, the bible says there are a lot of stars. I don't think it's surprising that a culture that hadn't discovered Zero yet couldn't count them all. Is this really a convincing argument that it was inspired by God?

The question comes down to, what is more likely? Is it more likely that this book is the literal truth which the only true God revealed to people 2-6 thousand years ago in which he developed a system where he would forever after reveal himself to people only in a falling in love type experience and those peoples acceptance of that experience, and the acceptance of several empirical truth statements (jesus was born of a virgin, enoch went into heaven in a fiery chariot) that are joined to it, would determine the salvation or damnation of these people for eternity? - or, is it more likely that this book is the mythology of a group or "race" of people, similar to the mythologies of the people around them, joined with turn of the millenium writings on doctrine, similar to philosophy written by others around that time, about a cult with a central figure that performed miracles and made claims, similar to claims and miracles made before that time, during that time, and all throughout history? Is it more likely that Christianity is unique in its non-empirically supported claims, or like every other group that has developed non-empirically supported religious claims? Should we accept any of these claims because of ancient mythology and mountain top experience? I think you know my answer.

Da Bears

I've been watching the Travel Channel all day. I think I'm quite a conservationalist. I get really excited when they talk about how back in '95 they introduced 30 wolves back into Yellowstone, after they had been hunted to the point of extinction, and now their numbers are over 300. Maybe I should go study forestry or something else useful only to become a park ranger (and make no money the rest of my life).

I'm never gonna decide what I want to do when I grow up.

Galaxies

I love this stuff. This picture had 50,000 galaxies in it, you can zoom in and see the shape of some of the closer ones - spirals and stuff. 80 years ago, we didn't even know that other galaxies existed outside our own. We have only observed a few other planetary systems in our own galaxy so far - there are billions more to be observed in the Milky Way alone - plus billions of other galaxies that have billions of stars thatmay have systems, if we ever progress that far technologically.
