Delta is the symbol used to denote change in mathematic and scientific equations. For example, students are taught that velocity = change in position / change in time. That equation is often given as v=(x-x)/(t-t) [with the first x and t having subscript 2 and the second x and t having subscript 1 to denote that they are two discrete location and time coordinates, but I can’t figure out how to get subscript characters in WordPress!] This, of course, is more simply written as v=∆x/∆t. In other words, a delta represents not some nebulous concept of change but a specific, measurable change between two distinct points in time (or space).
This week’s challenge, focus, was almost too easy! I do a lot of macro and/or food photography so focus is very important. I’ve had many a photo come out terribly, with the focus just slightly off or the depth of field just a bit too wide or too narrow. On occasion, though, as the prompt reminds us, sometimes an out of focus photo can be beautiful in it’s own way. Continue reading “Out of Focus: WPC”
I’ve recently handed in two term papers and, as if on cue, the skies darkened and the temperature dropped into the low 60s. So on top of the let down at the end of a hard year, I’ve got a sinus headache that won’t quit. Not that writing the papers, finishing the papers, or having this headache have stopped me from baking, they’ve just stopped me from blogging about it. So stay tuned for some brilliant baked goods (plus at least one crafty project). But in the meantime, here’s my entry for the latest weekly photo challenge: Evanescent. Continue reading “Dandelions: WPC”
I’m in the middle of writing two final papers at the moment, so forgive the brevity.
I’ve always been fascinated by reflections, so I had no lack of photos for this week’s photo challenge. I decided to use some I took a while ago at Lincoln Center. I love the reflections coupled with the high contrast of the dark and light. Continue reading “Reflection: WPC”
I admit I didn’t march in the Women’s March. I had a lot of homework and I’m not particularly fond of crowds or being up at 7 am on a freezing winter weekend. But I couldn’t resist heading to the March for Science. Not only was it being held at a more civilized hour and in my neighborhood, I’m a scientist (alright a political scientist–but my field employs the scientific method and depends on government grants too!)
I’m so glad I went. Continue reading “Earth Day and the March for Science: WPC”
Cee’s Black and White Photography Challenge has been alphabet themed recently. At some point I’ll have to catch up–but here I am, starting at I and J.
I is for icing.
J is for Johnny jump ups.
They’re both dense! *crickets chirping*
I was actually planning on taking this week’s challenge literally, just as I’ve done the last couple weeks (with “green” and “atop“). I like the idea of working through different elements of photographic composition–color and perspective, respectively, and now texture. Fun!
But as I was sitting doing one of my readings this week, I couldn’t help but interpret “dense” as “(of a text) hard to understand because of complexity of ideas.” I’d already selected and edited my “dense” as in “having the constituent parts crowded closely together” photos. So they’re here too!
