Profile


Photo Synthesis is a rotating showcase of the best science photography on the web.


tedkinsman.jpgTed 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 www.sciencephotography.com Kinsman also teaches advanced placement physics at Brighton High School in Rochester, NY, he also teaches advanced macro-photography at Rochester Institute of Technology.


BNSullivan150x200.jpg 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.

Bobbie lives in Hawaii with her husband. Together they produce TheRightBlue.com, where you can see more of Bobbie's photos and writing.


bjeffersonbolenderOpt.jpg 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.

See more of her work in her photo stream on Flickr and the website atarizona.com.


jurvetson.jpg 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 here.

Steve is a Managing Director of Draper Fisher Jurvetson (DFJ.com), a leading venture capital firm with affiliate offices around the world.

He was the founding VC investor in Hotmail, Interwoven, and Kana. Previously, he was an R&D Engineer at HP, and his prior technical experience also includes programming, materials science research, and computer design. He has a B.S. in Electrical Engineering, an MSEE and and MBA, all from Stanford University.


alex.jpg 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.

Alex's galleries are viewable at www.alexanderwild.com, and he normally blogs at Myrmecos Blog.

Rocket Drag Races

Posted on: June 21, 2009 10:18 PM, by Steve Jurvetson

Drag races add a bit to all of the excitement, not only for their competitive elements, but also because the action fills the skies, sometimes with mishap.

This Great Gizmo drag race was sponsored by Wildman Rocketry at LDRS27 in Argonia, Kansas, with each flying the same kit:

Great Gizmo Race

It's a rare treat to see them all roar off the pad at the same time, and then spiral around like Keystone Cops. The sparky one at the bottom went into a death spiral and crashed into the farm dirt near me. (Since these are all the same rocket kit, I suspect the difference in flight dynamics derive from differences in nose cone weight.) This is one bank of rockets; there was a second bank off to the left launched at the same time.

Then the big birds came out, with each flying the same sparky M-size motor from Animal Motor Works:

Three Sparky Horsemen
Three rocketeers, scattered across the globe, coordinated designs over the Internet to converge for a surprisingly fair drag race (I suspect Thermite igniters). The rocket on the right came from Australia to rural Kansas for this launch.

Here is a remarkably similar start, but rapid separation (0.5 seconds later) of M motor contestants at DairyAire this summer:
Glow Sticks Big Drag Race

These were a special collections of very close races. Much more typical, especially for me it seems, is to have my rocket still chuffing on the pad while the other rocket screams supersonically out of sight. Here's an example video of a drag race of my Milk Rocket versus Erik's (which leaves the frame before mine gets going). It's mostly interesting for the smack-talking audio, typical of these events.

Not to be outdone by Team Numb's Beer Keg launch, I improvised with what I had in the desert, and sent my son's milk bottle up in his Nike Smoke rocket on a K550... and got it 100 ft. higher than the beer (6,258 ft. per the onboard HCX flight computer).

I was racing Erik's GLR Vertical Assault flying on one of my favorite motors, a CTI L730 which burns a thermoplastic propellant from a Canadian aerospace company. He just rips off the pad and out of the frame, and disappeared into the sky.

I cut a few minutes of mystery from the middle of the video as we were looking up in the sky for our rockets. We both packed orange chutes and only one orange chute was visible in the sky... Who's rocket was it, and where did the other one go?

Both rockets were recovered in perfect shape. My chute was in sight overhead, and Erik's was discovered several hours later by others). I shared the "rocket milk" with Team Numb as they were having cookies on Sunday morning. The motor warmed the milk to body temperature... just like mama used to make...
