Quite a few months back, perhaps as much as a few years ago, I started thinking about how and when I began to embrace critical thinking. I mentioned before that I used to believe in a whole lot of crap and gradually left it all behind, but was there some particular event that started this process? We like

More Darwin (less cowbell)
Nice day out there, so it’s time to go see if there’s anything to be captured in mid-February, with the added incentive that it’s Charles Darwin’s birthday and I should illustrate natural selection. Hmmmm.
Okay, let’s start with the tiny winter flowers that can be found here in North Carolina, in corners and areas that see little traffic. With some poking around, I managed

Walkabout podcast – Marvel of design
I delayed this one slightly to serve as my Darwin Day post ;-)
I freely admit that there are some really stunning things to be found in nature – in fact, that’s what many of my ‘Too Cool‘ posts are intended to highlight. Predator/prey relationships, highly
Grecian troublemakers
This is a revisit of a subject that I first broached in this post, which I felt needed more examination. So let’s return to that radical concept of Phi.
Phi is a mathematical ratio that, curiously enough, has more than a few close representations in nature. It is an irrational number, one of those decimals that go on forever, but usually shortened to 1.618. If you create a rectangle
But how uncertain do you feel?
I have very mixed feelings about emotions [now, there’s a sentence of remarkable profundity.] As manifestations of internal functions to provoke behavior that benefits our species, they are distinctly important, but too often, they’re not specific enough, or they’re too easy to fool, producing behaviors that don’t really benefit us and are sometimes quite detrimental. I hate
Chasing megapixels
Some time back, I’d started a post on this subject, partially in response to a thread somewhere, but when I took too long to finish it I realized it was, in webby terms, no longer current, and simply let it go. But after another prompting, this time from The Straight Dope, I decided it’s worth pursuing anyway, and may provide a little insight into the whole digital photography thing.
Too cool, part 17: Feynman lectures
I’m really not one for quoting others. It’s easy enough to find anyone who has the same point of view that you do, and hold them up as an example of someone famous or prestigious that ‘proves your point.’ This is perhaps doing a disservice to the other reasons to quote someone, such as appreciating the eloquence of their delivery, or simply recognizing diverse points of view,
An open letter
This post was fostered by an exchange on Panda’s Thumb and simply needs to be said. This is an open letter to everyone who might call themselves devoutly religious, creationist, conspiracy theorist, new age or alt med supporter, paranormal or psychic believer, and so on. Or anyone that has ever used the phrase, in any form, “Science doesn’t know everything.”
It’s simple.
The ethical responsibility of scientists
Sometimes, we humans get a cultural belief or concept stuck in our collective heads, something typically called a meme, and therefore think that this has importance solely because it’s repeated. Some sociologists have expressed the idea that this is exactly what culture is, and there’s an interesting theory that memes actually go through a process of natural selection.
On the plus side
I apologize for being away so long, to all of those who noticed – to the rest of you, yeah, love you too. I’ve been busy with two online courses, a few different projects, and a minor illness. This is partially why I’m glad I’m not on any kind of posting schedule, even a self-imposed one: I’d be obligated to produce something that, more likely than
