GoPro as scientific instrument?

Yes, it's probably the most ridiculously narcissistic device ever invented. Without doubt, more information coding and storage has been wasted on self-aggrandizement with this little camera than in the entire previous history of egomania.

But like many scientific sensors and instruments of the past--like the telescope, microscope, oscilloscope, geiger counter, IR and X-ray film, EEG, even the scientific method itself--the inexpensive, yet incredibly capable GoPro camera platform is providing a new sensory organ that allows people to see and interact with both the familiar world and its hidden (to us) aspects in ways no one ever has before.

Seeing outside of the expected and familiar is the first step in the creation of new knowledge whether created by art, or by science. 

Here are a few of the most thought-provoking GoPro videos I've seen. Post others in the comments...

or bronze gears...



or DNA (okay, this is just digital storage)...



so, how about this?...



...or there's water. Kudos to this guy for programming his fluidic logic gate simulation with a crappy video game!

Swimming fish cause ocean currents!

This is a pretty incredible twist on the whole ocean current/climate change story: turns out that the motion of the ocean can't be entirely accounted for by weather. What's the missing energy input? Swimming fish & other sea creatures.

"If swimming generates tide-scale forces, then 'it has an impact on global climate'. This is a rather novel twist to the whole climate story,” said William Dewar, a Florida State University oceanographer.

So, apparently overfishing causes climate change in addition to its other issues.
