The Most Incredible Volcano Video of ALL Time

Published on Sep 17, 2012 by geoffmackley

The Most Incredible Volcano Video ever shot ! Geoff Mackley, Bradley Ambrose, Nathan Berg, after an epic struggle with the weather for 35 days, we became the first people ever to get this close to Marum Volcano's famed lava lake on Ambrym Island, Vanuatu. Coming within 30 metres of the lava lake down a watercourse, it was possible to stand the heat for only 6 seconds. With Fire Brigade breathing apparatus and heat proof proximity suit it was possible to stand on the very edge and view the incredible show for over 40 minutes.

For those of you "upset" with the use of a watermark on this video it may pay to consider for a moment that my expeditions are funded by the sale of such footage.

This expedition took nearly 2 months and cost many tens of thousands of dollars, not to mention the dangers involved.
As has been seen time and time again, there are many media organizations out there who think nothing of downloading peoples footage, re uploading to their own websites with adverts etc while others pay for the legitimate use of it. Its straight out theft.

Thanks to the viewers who understand why I have to deface such a good video with a watermark.

NASA | Magnificent Eruption in Full HD

Published on Sep 5, 2012 by NASAexplorer

On August 31, 2012 a long filament of solar material that had been hovering in the sun's atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled away from the sun at over 900 miles per second. This movie shows the ejection from a variety of viewpoints as captured by NASA's Solar Dynamics Observatory (SDO), NASA's Solar Terrestrial Relations Observatory (STEREO), and the joint ESA/NASA Solar Heliospheric Observatory (SOHO).

Human Powered Helicopter Altitude Record of 8 Feet

Published on Aug 28, 2012 by TeamGameraHPH

Team Gamera is back and flight testing their modified version of Gamera II Human Powered Helicopter at the PG Sports and Learning Complex in Landover, MD.

With new pilot and incoming UMD Freshman Henry Enerson in the cockpit, a maximum altitude test flight was attempted. Needless to say we were not quite expecting what happened next. Henry smoothly pedaled Gamera up to just over 8 feet (2.5 meters) altitude and had a controlled descent for a flight time of about 25 seconds. This is not an "official" record but is certainly the highest a human powered helicopter has ever reached.

Our goals are to continue flight testing to achieve a 3 meter (10 ft) altitude as part of the AHS Igor I. Sikorsky Human Powered Helicopter Competition ('The Sikorsky Prize'). Stay tuned to this youtube channel as more historic flights are achieved and posted!

Bill Nye: Creationism Is Not Appropriate For Children

Published on Aug 23, 2012 by bigthink

Evolution is the fundamental idea in all of life science, in all of biology. According to Bill Nye, aka "The Science Guy," if grownups want to "deny evolution and live in your world that's completely inconsistent with everything we observe in the universe, that's fine, but don't make your kids do it because we need them."

Transcript--
Denial of evolution is unique to the United States. I mean, we're the world's most advanced technological—I mean, you could say Japan—but generally, the United States is where most of the innovations still happens. People still move to the United States. And that's largely because of the intellectual capital we have, the general understanding of science. When you have a portion of the population that doesn't believe in that, it holds everybody back, really.

Evolution is the fundamental idea in all of life science, in all of biology. It's like, it's very much analogous to trying to do geology without believing in tectonic plates. You're just not going to get the right answer. Your whole world is just going to be a mystery instead of an exciting place.

As my old professor, Carl Sagan, said, "When you're in love you want to tell the world." So, once in a while I get people that really—or that claim—they don't believe in evolution. And my response generally is "Well, why not? Really, why not?" Your world just becomes fantastically complicated when you don't believe in evolution. I mean, here are these ancient dinosaur bones or fossils, here is radioactivity, here are distant stars that are just like our star but they're at a different point in their lifecycle. The idea of deep time, of this billions of years, explains so much of the world around us. If you try to ignore that, your world view just becomes crazy, just untenable, itself inconsistent.

And I say to the grownups, if you want to deny evolution and live in your world, in your world that's completely inconsistent with everything we observe in the universe, that's fine, but don't make your kids do it because we need them. We need scientifically literate voters and taxpayers for the future. We need people that can—we need engineers that can build stuff, solve problems.

It's just really hard a thing, it's really a hard thing. You know, in another couple of centuries that world view, I'm sure, will be, it just won't exist. There's no evidence for it.
