Three reasons I love Battlestar Galactica (1978)

Here are my top 3 reasons to love Battlestar Galactica (1978):


The premise was that life didn’t start on Earth and they were actually searching for this “legendary” planet called Earth.


The show has 6 foot tall Cylons with one red eye moving side to side, which was also used for K.I.T.T. in the 1982 TV show Knight Rider! Both shows were written by Glen A. Larson, along with The Fall Guy and Magnum P.I.!


The most futuristic and advanced computer imaginable, the Tandy (Radio Shack) TRS-80, was used onboard the ship!

Why do you love Battlestar Galactica (1978)?  Post your reasons below in the comments!

Thanks for your interest!


Photos from Star Wars exhibit

Back in April, the Star Wars traveling exhibit titled “Star Wars: Where Science Meets Imagination” was at the Orlando Science Center.  It was pretty amazing.  The exhibit is now in Indianapolis and will complete it’s 20 city tour in San Jose California later this year (2013).

They had lots of great props, costumes, and models from various movies.  Plus, they had some nice interactive stations and learning stations for the kids.

Here are a number of photos that I took of the exhibit.  Click below to see the entire collection of photos that I took.  Flash photography was not allowed and I was just using my iPhone, so the quality of these photos is not the greatest.

NASA wants YOUR input on the future of the space program!


NASA Press Release dated: June 5, 2009


WASHINGTON — NASA is inviting the public to make its voice heard as a panel of experts undertakes an independent review of planned U.S. human space flight activities.

NASA has created a Web site for the Review of U.S. Human Space Flight Plans Committee to facilitate a two-way conversation with the public about the future direction of the agency’s space flight programs. In addition to providing documents and information, the site will allow the public to track committee activities, receive regular updates and provide input through Web 2.0 tools such as Twitter, Flickr, user-submitted questions, polls and RSS feeds. Additional features and content may be added as the committee’s activities continue.

“The human space flight program belongs to everyone,” committee chairman Norman Augustine said. “Our committee would hope to benefit from the views of all who would care to contact us.”

Anyone may use the Web site to submit questions, upload documents or comment about topics relevant to the committee’s operations. The committee will conduct public meetings during the course of the review. The first will be held June 17 in Washington, D.C. An agenda for this meeting will be announced soon. Time will be set aside for public questions and comments to the committee members. No registration is required to attend.

Artists and Scientists Unite!

. NASA Art Contest Website at Langley

NASA sent out a press release today about this cool art contest for college students:

Aug. 23, 2007

Langley Research Center, Hampton, Va.

RELEASE: 07-179


HAMPTON, Va. – A new NASA contest encourages university art and design students to partner with science and engineering departments to create art representative of living and working on the moon. The goal is for students in the arts, science and engineering to collaboratively engage in NASA’s mission to return humans to the moon by 2020, and eventually journey on to Mars and other destinations in the solar system.

The Advanced Planning and Partnership Office at NASA’s Langley Research Center in Hampton, Va., is sponsoring the “Life and Work on the Moon” contest. Winners will receive cash prizes up to $1,000. Winning artwork also will be exhibited online and across the country.

Students in architecture, industrial design, computer design, the fine arts and other disciplines are invited to submit entries in one of three categories: two-dimensional art, three-dimensional art or digital art. To ensure artistic concepts reflect the realities of the harsh lunar environment, art students are strongly encouraged to consult with science and engineering students and use NASA’s online resources.

A volunteer panel of judges will represent NASA, other government agencies, universities, industry and the professional art community. Judges will evaluate artistic qualities and whether the entry depicts a valid scenario in the context of the lunar environment.

In sponsoring the contest, NASA hopes to encourage more collaboration among scientists and engineers and the artistic and creative communities. Such collaboration may generate new ideas for living and working in extra-terrestrial environments, resulting in more successful long-duration space missions.

Winners of the contest will be offered the opportunity to exhibit their work in NASA facilities and science museums. An online public gallery will be available through a partnership with NASA’s Classroom of the Future, maintained by the Wheeling Jesuit University Center for Educational Technologies in Wheeling, W. Va., and the Christopher Newport University Institute for Science Education in Newport News, Va. Christopher Newport University will provide cash awards for top prizes.

Entries are due no later than December 1, 2007, and results will be announced in February 2008. A high school version of this contest is planned for the spring of 2008.

I’m a lab rat in a motion sickness study

I recently volunteered to be a test subject in a NASA/KSC study on motion sickness. I call it the “spinning chair of death” study for fun, but it’s really not too bad. Today was my turn in the chair and it was actually a breeze and I never even felt queezy. I guess I’m not very prone to motion sickness because I can count on one hand the total number of times I’ve ever felt motion sick.

Here are some details of the study:

The chair is actually a racing seat mounted on a wooden box. The wooden box holds all kinds of electronic gear (biological sensors) and a laptop PC powered by a car battery and an inverter. The wooden box is connected to a gearbox and a motor that spins it at 15 RPM’s or about 4 seconds per revolution. It’s not real fast. The whole contraption is also tilted from vertical 15 degrees. It’s this tilt combined with the rotation that gives your inner ear a real workout and causes most people to get motion sick.

After my test is complete.
Photo of me in the chair after my test was
complete and all the sensors were removed.

After filling out about 5 pages of medical history paperwork, the doc weighed me and then put 2 sets of EKG pads on my chest and side. One set was for local recording on the laptop PC that spun around along with the chair, and the other set was for wirelessly transmitting across the room so that the doctor could track my health during the test and stop the test if things went south. Then they sat me in the racing chair and strapped me in fairly snugly. It’s a pretty comfortable chair.

Then they hooked a constant blood pressure cuff on my left middle finger. This little cuff measures your blood pressure every single time your heart beats. It’s pretty cool. It inflates just like the standard cuffs do, but it pressure pulsates with your heartbeat and somehow the thing uses an infared beam or something to look at your blood flowing in your finger. I really don’t know how the thing works, but it’s a cool little device.

The last thing they hooked up to me was even cooler than the constant blood pressure cuff. It was a doppler blood flow sensor that was mounted against my right temple on my forehead. It’s just like the sonogram device a doctor uses to find the heartbeat of a fetus in the womb. And it sounds exactly like that, because they turned the sound up when they were installing the thing. They put this little helmet thing on my forehead and tightened it down snugly. Then they played around with the position of the doppler sensor on my temple until they found just the right artery and just the right position on that artery. The doctors and technicians were all crowded around the laptop watching the realtime plot waves while the sensor was being positioned. This sensor was difficult for them to get just right, but when they got it, it was rock solid … even when I moved my head around.

Then the doc gave me final instructions on the hand signals that I would be using during the test. Every minute during the test, the doc would ask me to rate my motion sickness symptoms on a scale from 1 to 5. With 1 being no symptoms, to 5 being “I think I’m gonna be sick so stop the test right now!”. Then they started the test with a 5 minute waiting baseline. I breathed deeply and tried to relax for the baseline measurements. 5 minutes is a long time when you’re waiting for it to pass in silence. They wanted all subjects to perform the rotating part with their eyes closed, so I closed mine for the baseline also.

Then the rotation started. It was to last 15 minutes or until I felt sick. Every minute the doc asked me to hold up fingers for my symptoms. For the first couple of minutes I felt like I was moving exactly as I knew I was moving. During the rotation, my body and head were being forced by gravity forward, to one side, backward, and then to the other side.

But then my brain kind of switched things around and it didn’t feel like I was spinning anymore. My head and body were still being pushed forward, to one side, backward, and then to the other side, but my brain made me feel like this motion was because I was being translated around on an air table and always facing the same direction. Imagine your hand on a hockey puck on an air table or on an ice rink. Now move (translate) the puck around in a large circle without rotating the actual puck. This is what I felt like I was doing now and it didn’t feel bad at all. As a matter of fact, I probably could have fallen asleep doing this if given another 15 minutes or so. After a while it was actually soothing. If my brain hadn’t switched me from feeling like I was rotating to feeling like I was just translating, I don’t know if I’d have made it.

After the 15 minutes were up, I had given them 15 motion sickness symptom scores of 1 with my hand signals and had no symptoms at all anywhere. No dizziness or anything going on in my stomach. During the last cycle, the chair slowed down and then finally stopped in the same position it started in. When it finally stopped completely, I felt my brain for just a couple of seconds continue to want to rotate and I’ll bet my head even twitched a couple of times towards the direction of rotation. But that passed after just a couple seconds and then I felt perfectly normal. They had another 5 minute period of waiting and then the test was complete.

The test was fun and I would do it again if given the opportunity. If I wasn’t having so much fun in my current organization, this department would actually be a pretty cool place to work. My buddy Dave works in this department and actually built the “rotating chair of death” and put together all the electronics that go with it.
