esiegel | October 20, 2009Ever see a picture of a Solar Prominence before? If you have, you'll recognize these loop-like features leaving the Sun's surface and ending up in the Sun's corona:
Well two spacecraft designed to monitor the Sun, Stereo A (which stands for "Ahead" of Earth) and Stereo B (which stands for "Behind") just imaged a 30-hour Solar Prominence during September 26th and 27th. What did they find?
This video, which gives three minutes worth of spectacular views of this eruption on the Sun. Have a look:
Thanks to APOD for providing the snapshot that inspired this!

There's a chance he could be a male Phidippus cardinalis -- a bit of research reveals both P. apacheanus and P. cardinalis are found in this area of Oklahoma.

This macro video of an adult male Phidippus mystaceus Jumping Spider is really interesting. He does have an inordinate fondness for jumping onto the camera lens, though! Jumping spiders are my favorite types, although they do awaken my inner phobia at times.

Richard Dawkins responds to some hate mail sent by those architects of brotherly love, god's own followers, christians.

It's the moment of judgment for one fool who says there is no God. Christians, get ready to laugh as he learns his eternal fate!

Irena Salina's award-winning documentary investigation into what experts label the most important political and environmental issue of the 21st Century: The World Water Crisis.
Next week, starting Monday, I will show you the entire film because this film is not yet in general circulation.
The critics say:
"An astonishingly wide-ranging film. An informed and heartfelt examination of the tug of war between public health and private interests." - New York Times
"Lively and engaging...Smartly Done" - Los…

I've been telling you about the perils of plastics, but some of the worst plastics offenders are molecular and cell biologists. Nearly every experiment that we do uses incredible amounts of plastics. In cell biology or molecular biology labs the emphasis is on working sterile, quickly and reproducibly. So companies have been selling all these incredibly useful products to life science labs: sterile plastic tubes of all shapes and sizes, single wrap multi-well tissue culture plates, sterile plastic dishes, sterile…

This is a message by Captain Charles Moore, an oceanographer who pioneered the study of plastic debris, and was recorded during the Strategic Council on Plastic Pollution convened at the Google Campus in Mountain View, California on June 4, 2009. It was the first meeting for the council on plastic pollution, which was recently formed to raise awareness of this rising threat to the world's oceans. Council member and marine biologist Dr. Wallace J. Nichols, noted that "we are finding plastic in the stomachs of sea turtles,…

That's right. She's not allowed to have candy yet, but she's already gearing up for Halloween...
The pumpkin bucket is actually a bribe-- I bought it for her to play with while we waited for her prescription to be filled yesterday. This is in fine family tradition-- my father used to buy presents for my sister and me when he had to take us shopping for my mother's birthday...
While we're not going to try giving her candy any time soon, SteelyKid is making great progress in the area of eating, as can be seen in the video…

The center of the North Pacific Gyre is a relatively stationary region of the Pacific Ocean (the area it occupies is often referred to as the horse latitudes). The circular rotation around it draws waste material in and has led to the accumulation of flotsam and other debris. While historically this debris has biodegraded, the gyre is now accumulating vast quantities of plastic and marine debris. Rather than biodegrading, plastic photodegrades, disintegrating in the ocean into smaller and smaller pieces. These…

This is a lesson in observation. This is a North American animal. I know what this is (and I knew as soon as I saw the still image on the video) but I am asking you: what is this; hummingbird or insect? And for a bonus, can you tell me the species?
This is a Common Clearwing, also known as the Hummingbird Clearwing Moth, Hemaris thysbe.

The life cycle of a honey bee is presented in this video as an example of complete metamorphosis, the development of an insect from egg to larva, then pupa, then adult. Moths, butterflies and wasps also develop with complete metamorphosis. Some aspects of beekeeping are also discussed in this video.

Barney: Next they're gonna show my movie.
Bart: You made a movie ?
Barney: I made a movie? I wonder why there was a picture of me on the cover of Entertainment Weekly.
Earlier this year, a documentary film challenge was issued internationally. The goal was to make a movie about one of this year's two themes: hope or fear.
A group of Oregon filmmakers, The Cingulate System, called me up at work and asked if they could interview me for their film about Dark Matter. The challenge was to make a documentary, from scratch, in under a week. The film premiered April 8th right here in Portland…
rallain | October 13, 2009The last time I looked at this projectile motion lab, I was confused. My different methods for measuring the launch speed of the ball were not even close to being consistent. So, I am bringing out the big guns - video. I made a video of the ball shot both horizontally off the table and vertically. No point posting the whole video (unless you really need it), but here is a screen shot of what the setup looked like.
These videos were made with my flip video camera, it doesn't have adjustable shutter speed so that there is some blur. Also, notice the carbon paper on the floor. This is so…

A flying hummingbird flaps its wings up to 70 times per second (its heart rate can reach 1,260 beats per minute). This video slows down a flying hummingbird so we can watch how it flies and hovers in front of a hummingbird feeder.
Here's what hummingbirds look like when not slowed down;
This was filmed in British Columbia, Canada. Soundtrack is 'The Orient' by Alex Yiannaras.

This is a really interesting video about soap bubbles -- how they work and what we can do with them. The slow motion footage of a bursting bubble is especially interesting to watch.
rallain | October 12, 2009I put together this short presentation on fake videos for a class. What the heck, I will also put it online so that maybe some other people can use it. So, here it is. I have it in many forms. First, a video of me going through the talk. Then I have the keynote and PowerPoint files with the movies. Feel free to use it as you see fit. You might want to modify some of the files, I have no problem with that.
