Followup: The artful dodger

In the previous post, I took Philosopher of Science Elliott Sober to task for a relatively simple question that he’s been flogging at the expense of huge amounts of oxygen and electrons – and at the same time, ripped philosophy in general. I’ll be honest and say that I would really like someone to [...]

Final answers aren’t

Over at EvolutionBlog and Why Evolution Is True, Drs. Rosenhouse and Coyne have taken down the same philosophical question posed by Dr. Elliot Sober, to wit: Can science establish that genetic mutations are not caused by god?

It is questions like this that have guided my abiding dislike of philosophy, since a tremendous amount [...]

A year goes by fast

Last year about this time, I published a post about my little friends the fishing spiders, whom I call ‘friends’ not because we hang out and hammer down Pepsi together, but because my first photo sale featured one as a subject. Lately, a few have been making themselves obvious, clearly begging to be featured again, so who am I to crush their little spirits? And I say with all honesty, it’s not that I’m avoiding bunny rabbits and ducklings, it’s that I simply have not seen anything cute at all. But still, I know some people don’t want to be greeted with spiders all the time, so I’m including the detailed pics below the break.

A little over a week ago, while staging the photo for the previous post, I espied something that can occasionally be found at the edges of ponds and streams that have plenty of reeds, seen to the left: the molted exoskeleton of a fishing spider. Spiders, and most insects, shed their ‘skins’ as they grow larger, splitting the chitin and squeezing out backwards, and then usually hiding for a while since their new exoskeleton is soft, leaving them much more vulnerable to predators. The translucent molt is left attached to whatever surface was handy, usually mistaken for a dead insect, but it’s instead a clue to be watching for the former owner nearby. When I sat down to take this image, I soon spotted the culprit hiding in the tall grasses. With a stick, I carefully flushed him out, whereupon he panicked and scampered for cover practically underneath me, but then froze and held perfectly still for some really tight closeups.

The road’s longer than it looks

Okay, let’s do a variation of an exercise I perform with my students sometimes. I’ll preface this by saying, this isn’t a trick question, nor is there a ‘right’ answer. It’s simple: look at this image and tell me what you can glean from it.

Well, it’s a stream or pond, with a rock [...]

… and part two

There are actually two themes I’m continuing here. The first is the limits of our knowledge, which is a “half-empty” perspective; there’s a better way of expressing it, which we’ll get to in a moment. The second theme being continued here is special efforts made by scientists to communicate their work to the general [...]

There isn’t always a complete answer, part one…

For those of you who have been hanging on the edge of your seat, checking thrice daily to see if I’ve offered an update, I apologize for keeping you in suspense. Actually, no I don’t – suspense is good for you, and anxiety strengthens the heart. Well known fact.

Anyway, I mentioned trying to [...]

That’s 154 to you and me

Source: Hubblesite.org

On this date 22 years ago, the Hubble Space Telescope was borne into space on Shuttle Discovery, the one that recently did its last flyby over DC (well, okay, it had help) before delivery to the Udvar-Hazy center. The Hubble will be retired soon, and while this is viewed with some [...]

Back atcha

Last year, I did a post on macro photography that featured some detail pics of a Giant Water Bug, also called an Electric Light Bug but better known by the scientific name Belostoma flumineum. This post totally rocked the internet, and by that I mean, was just another post on just another blog, probably [...]

How’s that sound?

This is a follow-up to the earlier book review of Brain Bugs, by Dean Buonomano. The author raised an interesting bit of speculation within that I wanted to examine – first noting that the likelihood to establish any such speculations as accurate or even worthwhile is pretty slim. This is more of a thought [...]

Book Review: Brain Bugs

A friend of mine (yes, I have some, hush) handed this book over to me, because we’d had numerous discussions related to the content while he was reading it – and I was the one who initiated them without even knowing about the book. Anyone familiar with the content of this blog may be [...]
