On this page, you will find links to some of my science videos. I’ve created and published several peer-reviewed videos through the science agency, the U.S. Geological Survey. These videos mainly focused on my research and were designed for a broad audience. In a few cases, I spotlighted the work of colleagues. In general, I tried to show how scientific research contributes to better conservation and management of our natural resources and how such information relates to the interests of the general public.  Also included on this page are videos showing other types of activities that scientists and students are involved in (for example, mentoring and conference attendance).

My other objective in making these videos was to show what it’s like to do scientific research and what real scientists look and sound like. I feel strongly that the average scientist needs to become more visible and familiar to the public. The average person is acquainted with doctors, lawyers, police officers, and other professionals, but most people have never met a scientist. Science videos are a great way to promote the value of scientific research while at the same time familiarize the public with the people behind the science.

Out of necessity, I did all of the story development, camerawork, narration, and editing and many of the animations for these videos. It was (and still is) a learning process. camcorder_klmckeeAfter an initial reluctance to spend time acquiring these skills, I found that I quickly and easily learned the techniques, which did not require expensive equipment/software or specialized training. What surprised me most, however, was how the process of making a short video about a topic forced me to reexamine what I knew about it (or thought I knew). New insights often occurred to me, for example, during interviews, researching background information, or putting the story together. Most of all, it was fun, and I rediscovered the passion for science and discovery that had become buried during years of competing for funds, for space in journals, and for recognition of technical accomplishments.

Note that all of these videos are free for anyone to use; all you have to do is grab the embed code (click on “share”, then “embed”, and copy the code) and insert the video into your website. All of the USGS videos went through an extensive peer and administrative review before they were approved for public release.

Bow Shock

The film opens with a time-lapse of an astronomical observatory framed against a backdrop of stars rotating slowly overhead in the night sky. We hear foreboding music that suggests the inevitable passage of time. Then we see astronomers at work inside the observatory gathering data from various sensors and arrays aimed at nearby asteroids, distant stars, and far-away galaxies. Throughout the night, the scientists and staff deal with routine problems such as a faulty temperature sensor. Meanwhile, the telescope camera is methodically snapping images of celestial objects.

 The next morning, a young researcher notices an unusual visual pattern in the night’s data—a curved distortion in space that resembles a bow wave generated by a ship moving through the ocean. Such interstellar phenomena are called bow shocks. But this one seems to be different. She takes her discovery to the director of the astronomical institute, who is taping a public service video about their new telescope and state-of-the-art camera, which captures the telescope’s entire field of view and creates a tridimensional cartographic image of the sky. After she finishes recording the voice-over for the video, the director tells the young scientist to put her images from last night’s work on screen. They watch as the computer stitches the images into a time-lapse view of the bow wave moving diagonally across the starscape. The young researcher estimates that it is traveling at about one third the speed of light. More calculations reveal that the bow wave is passing through the Oort Cloud in the outer reaches of our solar system. Whatever it is, it’s right on our doorstep.

Then, the director points out something really astonishing…the bow wave appears to be slowing down.

Although the scenes depicted above are fiction, they were filmed at a very real observatory, newly built for the purpose of wide-field optical surveys of the universe—the Observatorio de Astrofísico de Javalambre located at Sierra de Javalambre in Teruel, Spain. The film, entitled “Bow Shock” is a collaboration between filmmaker Javier Diez and scientists from the Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS). It was screened at the 2016 Imagine Science film festival and later archived at Labocine—a platform for new-wave science films. Watch it here: Bow Shock.

We are all familiar with science fiction films, which often take us to the edges of human imagination: The Day the Earth Stood Still, 2001: A Space Odyssey, Blade Runner. Alien. But Bow Shock belongs to a new genre called “scientific fiction”, which is a cross-fertilization of science fact and cinema. Emphasis is on getting the technical details right (something Hollywood often fails at) while telling a compelling story (something Hollywood excels at). In this particular film, the observatory and its research goals are real, but the story being told (about the bow wave discovery) is fictional. The idea is to provide an accurate account of the science while telling an intriguing story of how scientists of the future might use this new observatory to spot evidence of extraterrestrial life or other celestial phenomena. It’s an interesting approach that, in my opinion, has a lot of promise.

Bow Shock is a good example of scientific fiction—in this instance with actors playing the parts of scientists and observatory staff. The film is technically sound, well made with eye-popping visuals of astronomical techniques, and tells an intriguing story. Information about the observatory’s unique telescope and camera system is cleverly conveyed in the fictional story by having one of the characters record a public service video summarizing key features of the system. This approach is much more palatable than having a scientist give a dry, awkward speech on camera to introduce the observatory and its equipment. The fictional story about the bow wave does more than capture and hold the viewer’s attention while the more technical aspects are presented. It illustrates how astronomers look for unusual patterns in data collected with telescopes. By featuring the bow wave phenomenon, the film not only shows how astronomical research is conducted, but also how the observatory might make important discoveries in the future.

Of course, the biggest discovery would be to find signs of extraterrestrial intelligence. The film hints at this possibility, and the scientist actors speculate about how First Contact might occur and what response we might expect. This focus on First Contact takes advantage of people’s fascination with the question of whether life exists outside the Earth. There’s also a bit of historical irony in the film when the Spain-based astronomers recall what happened when Spanish conquistadors encountered the people of the New World. The analogy between early (Spanish) explorers sailing the oceans in search of new trade routes and spacefaring aliens sailing across the galaxy suggests to the viewer some potential outcomes based on known historical encounters. In other words, the film gives the viewer a lot to think about, but without resorting to exaggeration of the science.

Using scientific fiction to convey information about science is an interesting idea. Scientists often struggle to talk about their research in a way that is both understandable and appealing to the average person. Scientific fiction might be helpful in this regard, especially to show how a line of research might lead to breakthroughs in the future. By taking this approach, science filmmakers can spark people’s imagination about what discoveries a line of research may reveal. Humans are hard-wired to get their information in the form of a story. And, making such a film could be a lot of fun. Bow Shock was made by professional filmmakers and actors, but such a film could be made by a group of scientists or science students collaborating with film school faculty and students, for example. The scientists would ensure that the technical details were conveyed accurately, and the filmmakers would provide the cinematic expertise and acting talent. Coming up with a fictional story that is scientifically accurate would be challenging, but could be enlightening for the scientists involved. For more examples of scientific fiction films, check out the Labocine series.

Of course, you don’t have to make up a story to create a compelling film about science or scientists. In my next post, I’ll talk about taking a documentary approach to making films about science that resonate with viewers who otherwise have little interest in science.
