A conversation regarding origins

Reythia says:

Let me ask a question to all you atheists out there: if some sort of God didn’t create the universe (or at least the laws behind it), then what did? How did our universe get here? And, by the way, the answer, “It’s always existed,” isn’t an answer at all. After all, that’s the same as saying, “God’s always existed,” and if a good atheist can’t believe that, then he shouldn’t believe “the universe’s always existed” anymore!

It wasn’t exactly aimed at me, but I love the sound of my own voice/keyboard so much that I couldn’t resist answering. (more…)

American politics as I see them in 2008

Before I begin, I should note that I feel even dumber writing about politics than physics because I find politics to be much more confusing than physics. This is mostly due to how hard it is to get unbiased information (not to mention recognizing my own biases and trying to compensate for them). Also, there isn’t a clear “measure of success” analogous to experimental constraints placed on theoretical predictions that can be used to compare different policies. Finally, separating policy effects from other socio-economic factors is generally difficult if not impossible. As a result, one personality trait that I dislike in leaders is unquestioning certainty in the righteousness of their own actions and political positions. I want leaders to have the introspective critical thinking skills needed to see the flaws in their own ideas, the objectivity to recognize good points raised by their opponents and the humility to admit it.

Arguing about DRM

The following question about Digital Restrictions Management (DRM) was posed on Slashdot by laxcat:

Would someone please explain what exactly is wrong with DRM? If you have a problem with the concept of copyrights in general, then I can understand. But is there anyone out there that is cool with copyrights, but thinks DRM is bad?

I’m not trying to be an apologist for the corporations. I know they don’t care about the art or the artist, only money. That’s a given. But do they not have a right to protect their intellectual property? Are the detractors of DRM against the concept of intellectual property altogether?

The way I see it there is nothing wrong with the concept of DRM, only with the abuse of DRM. Is this a “slippery slope” argument?

I’m serious in my plea here. Someone please fill me in on what I am missing!

I couldn’t resist answering, and the ensuing discussion quickly became… lively. (more…)

Arguing with atheists about Einstein

I once noticed a (presumed) atheist make the following statement during an unrelated discussion about Buckminster Fuller:

Fuller did contribute some interesting stuff but some of his ideas were unworkable. That’s pretty common for most contributors/geniuses. Look at Einstein: some cool research, but he was highly disruptive in other areas (eg. quantum mechanics or putting religious beliefs before science).

Einstein was one of my childhood heroes so I wasn’t about to let that go unchallenged: (more…)

Brontosaurus never existed

When I was a college freshman, a fiery preacher named Tom Short would stand in a courtyard, evangelizing and arguing with any pedestrian who challenged him. More often than I’d care to admit, I found myself in that courtyard listening to him. It was like watching a car accident– horrible but so fascinating that I couldn’t look away. He spent a lot of time talking about Hell. He casually dismissed accusations that his homophobic rhetoric was indirectly responsible for a recent tragedy– the brutal murder of Matthew Shepard— by suggesting that Matthew was actually killed by other homosexuals. Other frequent topics included the pack of atheistic lies called “evolution,” and the argument that the Earth was only a few thousand years old.

Then one day, I heard him say: “Brontosaurus never existed.” Someone immediately responded: “That’s ridiculous! Of course (more…)

I’m never using RAID again

Hard drive failures have taught me to be very careful about backing up my data. Currently, I use a Redundant Array of Independent Disks (RAID) and Super Flexible File Synchronizer (SFFS) to provide two levels of data redundancy. I use RAID 1 (where two hard drives are exact copies of each other) which allows one drive to fail without shutting the system down. I don’t like the native backup utilities in Windows XP, so I bought SFFS to automatically backup my main machine’s data to a secondary computer every morning at 4AM.

This is the second PC I’ve built with a RAID 1 array. It’s also the last. (more…)

Levels of doubt

I don’t believe in anything with absolute certainty; I always allow room for doubt. How much doubt, though, depends on the type of statement:

Level 1 – Least doubtful

In my opinion, Descartes uttered the least doubtful statement ever: “I think, therefore I am.” I’d have no sense of self without making this assumption, so I definitely couldn’t inquire about anything else. (more…)

My theological journey

I grew up in the southern United States, a region famous for religious fundamentalism. My parents are Roman Catholics, and nearly all of my extended family identifies as Christian. I went to a Catholic primary school and later attended a Catholic high school.

Given that history, you might be surprised to learn that I’d always found the concept of God confusing. I was 10 years old the first time I recall thinking about this subject. These thoughts usually took place at the top of an oak tree (more…)

Stereogram puzzles

I’ve found stereograms entrancing ever since I first managed to “see” one. If you can’t see them, try viewing these images on one of those shiny new LCD monitors and focus on your own reflection. Be sure the monitor is perfectly level, and your head is perfectly vertical. Then use your peripheral vision to search the image for a hint of 3D structure but keep your face in focus. With any luck the image should simply pop into view. (Unless your eyes point in slightly different directions… right?).

These images fascinate me because they’re essentially tricking my binocular vision into hallucinating objects when I look “through” a pattern of (almost) random noise. I used to make my own stereograms using (more…)

Why do pigeons bob their heads?

Recently, I’ve started to wonder why pigeons bob their heads in such a violent manner when they walk. This habit seems like it consumes a lot of calories… don’t they need every bit of energy in order to fly? I don’t understand why natural selection hasn’t bred pigeons that walk without bobbing their heads. Wouldn’t they be more efficient and therefore more fit?

Here are some hypotheses I’m toying with to explain this behavior (more…)
