1Veritasium pulls it off in this little video, asking “how far apart are the moon and the earth?”. Along the way he sends a message about some pretty complicated subjects–the concept of scale, the size of the universe, and why it is difficult to use images alone to capture the reality of distance.
The recipe starts with “man on the street” interviews. These set up the misconception and in the process send the viewer the empathic message, “hey, you’re not the only one.” This is followed by a simple demonstration, using the long focus of the camera as an ally. Then simple graphics expand the idea and its implications. Finally, a 10 s summary: “The universe is truly bigger than we can imagine, and certainly bigger than we can draw to scale”.
Imagine a similar suite of videos on any difficult subject: enzymes, global warming, evolution. Imagine producing a suite of five or so on a science topic that interests you, posting them on your own Youtube channel. With your smiling face introducing each one. That’s one way to get noticed and to do a real service. As a debunker of myths. As teacher of science.
Any great, short, science videos out there you want to bring to a wider audience?

Ernst Haeckel was a seminal biologist and one of the first theoreticians in evolutionary biology. He was also a crazy good artist, and his 100 plates highlighting invertebrate diversity are available for download. The files are big enough to turn into small posters. Three of my favorites below the fold. Read the rest of this entry »

BrittanyB, a tuba-playing entomologist extraordinaire, has been tasked with developing methods to catalogue the diversity of our oribatid mites–little fungal grazers in the brown food web. Brown food webs convert the dead into minerals and carbon dioxide; they are nature’s cleanup crews, and a subject of endless fascination for us here in the AntLab. Our latest big project will explore how these food webs work at six sites, from the rainforests of Oregon to the alpine forests in Colorado, from the diverse forests of the Smokey mountains to even “diversier” forests in Panama.
So, after years of splashing around in the kiddy-pool of ant diversity–our first love, but relatively well known–we in the AntLab are moving into the calm, dark waters of the soil’s meso- and micro-fauna, starting with collembola (springtails) and oribatids (box mites). This requires a dive into the baroque literature of each group’s taxonomists–the high priestesses of biodiversity–and to learn the the secret language of the guild, the road marks and way signs embedded in form. We also must o photograph the little darlings, using cameras attached to microscopes. This involves fidgeting with lights, angles, magnification, and embedding media (some in the lab were relieved to know that the K-Y Jelly experiment was a flop, sparing them the embarrassment of a tube at every microscope station). Then these images must be stitched together and further manipulated with software. Lotsa variables, lotsa play, lotsa art.
For me, this is magical. For years, having simply counted petri dishes of “collembola” and “oribatids”, pushing them around into little grey piles before plopping them into centrifuge tubes, it is unimaginably exciting to finally get a good look at what I’ve been squinting at.
So here are a few of Brittany’s first attempts. This is gonna be fun.

Imagine a course where your read articles and watch videos at home, then come to class to work on problem sets. We’ll have more to say about this in the future, but I suspect if you want to work on your teaching chops, focus on how you interact with small groups, say, leading an exam review.
I mean, can you imagine a more succinct introduction to the alkali metals (love me some Na and K)?

We in the AntLab are learning through trial and error to photograph tiny things under the microscope. The goal is to produce web- based catalogues of critters from the brown food web, the microbes that decompose dead stuff like leaves, and the invertebrates that depend on them for food and shelter. The catalogue, which will go online sometime next year, is for our use as we quantify patterns of diversity, abundance, and body size across the New World forests. Hopefully it will help others interested in the same questions.
Here are a couple of photographs from Jelena Bujan, early efforts toward capturing the elusive beauty of Collembola, or springtails.

Alex Wild, of Myrmecos, and Alex Wild Photography, has fashioned his post-Ph. D. life into a career in insect photography. He is now an evangelist for taking better photos.
Check out a video of his recent presentation at UC. Davis. Or use this link to access his slide show.
Takehome: its about lenses, lighting, and composition.

Most scientists I know are map-geeks. What’s not to love about a 2-dimensional abstraction that captures gobs of information in an economical way? For those of us who love biogeography–the study of the distribution of life across the planet–how one renders the globe is vital to understanding where and why the diversity is. And the Mercator projection, the view of the world one sees from most North American classrooms, leaves, let us say, a little bit to be desired in that department. In the Mercator, the area of the continents around the equator–where most of the diversity of life can be found, is shrunk relative to poles. The story goes that Mercator, a German, devised a map that made Germany look as big as possible (but, in a karmic backfire, made Russia look even bigger, and let’s not even get started about Greenland).
So enter the The Peirce Quincunial, where the equator is a square. Sheer beauty.
Big tip of the hat to Victoria Johnson at The Awl.

Had a bad day? It could be worse.
Make sure to stick around to the end for the fun fact of the day.
I always suspected Pink Floyd would provide the soundtrack to The End (to mix popular music metaphors) but I was expecting, oh, I don’t know, Comfortably Numb, not Great Gig in the Sky.
Carpe diem, brothers and sisters.

What a perfect use of You-tube: a different short video for each chemical element. Kudos to the science geeks at Nottingham University and their Periodic Table of Videos channel.
Now imagine all the ways that you and your colleagues, with a $100 Flip video camera, can begin to change the world.
