Ted Kinsman is a scientific photographer that specializes in creating images for books, magazines, and television. His particular areas of interest are in x-ray radiography, high-speed photography, Scanning electron microscopy, and time-lapse cinematography. His work has appeared in numerous books and magazines ranging from Discover Magazine to Forbes. Recently his work has appeared on Gray's Anatomy and CSI New York. In addition to running 
B.N. (Bobbie) Sullivan has a strong affinity for the sea and everything in it. She first learned to dive in 1970 and has since logged thousands of dives. A wish to document the marine life she encountered prompted her to learn underwater photography more than 20 years ago. More recently, she began to write about the marine life she has photographed. A research psychologist by profession, she approaches her subject matter with the mindset of a scientist, but targets her writing to a general readership in whom she hopes to foster an appreciation for the ocean and its inhabitants.
B Jefferson Bolender is Training Coordinator of the State of Arizona's
program for disability awareness and assistive technology. Through
her travels she always has a camera at hand to photograph everything
from people to technology and nature. As a teacher of elementary
education, special education and art, her interests include a wide
array of subject matter with an emphasis on documentation with an
artist's eye.
Steve Jurvetson enjoys rocketry and photography and especially the pursuit of both in the Black Rock Desert. Some action photos and video links can be found 
Alex Wild is a postdoctoral researcher at the University of Illinois at Urbana-Champaign where he works on the molecular phylogenetics of various groups of insects. He is also a part-time photographer whose images appear in such venues as Ranger Rick, Smithsonian, BBC Wildlife, and even ScienceBlogs.
I have photographed jugglers several times in the past for physics text books. I have been impressed with the level of skill some jugglers can obtain. It is difficult enough to juggle three balls, four is more difficult, and fire is a another story. When objects move in a circle they can undergo some fairly complicated motions. What would be the best way to show this motion in a still image?
In this case the camera is panned by the juggler at a constant rate on a computer controlled pan head. When the juggler is about the center of the frame a flash is set off. The image shows both the flip the club does at the top of the throw and the uneven motion of the clubs as the juggler makes corrections to his throw as the motion is kept under control. This juggler is has been practicing for three years and is currently only 14 years old!

the hard part of juggling torches is that the end you can see is not the end you're supposed to catch...

Not that I'm a particularly good juggler, but I've always been told that juggling things on fire is the same as juggling them not on fire, except crowds are more impressed with fire :P
I hope I'm not giving away a magic secret here. I do love photos of fire juggling, poi, staff etc.

Actually, the fire adds drag to the torch, but just to one end of the prop, so the rotation isn't quite the same as, say, clubs or knives - torches fly much differently when they're lit, and the difference is very hard to describe in words.
BTW, they also give off a lot of heat, which wakes up a lot of ancient internal fear-type responses; dealing with this is also a necessary part of learning fire juggling.
