Winter Wonderland Multicopter

Winter Wonderland Multicopter

I hope everyone is enjoying a wonderful holiday season.  I think it’s a perfect time to share this amazing footage shot on a Cinestar Axis 3 Gimbal (with a Sony FS100 camera and 18-55 lens).  The gimbal allowed for the unrestricted 360 capture of the winter wonderland.

The multicopter flies incredibly smooth, even in the snowy conditions, and the slow-motion editing worked perfectly.  This almost makes me wish Texas was cold enough to get snow.

You can purchase the multicopter ready-to-fly for a cool $10,000 if you’ve got the money.  I would most certainly crash this thing the day I bought it.

Cassini’s Saturn

December 19th, 2012 | Space

The Cassini space probe was launched back in 1997 and made it to Saturn in 2004 after an interplanetary voyage which included flybys of Venus and Jupiter.  I recently stumbled across this article on the Huffington Post, and I decided it might be a good time to share my favorite images from the Saturn portion of Cassini’s journey.

Cassini Saturn 1

“A Splendor Seldom Seen

NASA’s Cassini spacecraft has delivered a glorious view of Saturn, taken while the spacecraft was in Saturn’s shadow. The cameras were turned toward Saturn and the sun so that the planet and rings are backlit. (The sun is behind the planet, which is shielding the cameras from direct sunlight.) In addition to the visual splendor, this special, very-high-phase viewing geometry lets scientists study ring and atmosphere phenomena not easily seen at a lower phase.

Cassini Saturn 2

Colorful Colossi and Changing Hues

A giant of a moon appears before a giant of a planet undergoing seasonal changes in this natural color view of Titan and Saturn from NASA’s Cassini spacecraft.

Titan, Saturn’s largest moon, measures 3,200 miles, or 5,150 kilometers, across and is larger than the planet Mercury. Cassini scientists have been watching the moon’s south pole since a vortex appeared in its atmosphere in 2012. See PIA14919 and PIA14920 to learn more about this mass of swirling gas around the pole in the atmosphere of the moon.

Peeping Mimas

Saturn’s moon Mimas peeps out from behind the larger moon Dione in this view from the Cassini spacecraft.

Mimas (246 miles, or 396 kilometers across) is near the bottom center of the image. Saturn’s rings are also visible in the top right.

Cassini Saturn 4

Angling Saturn

The Cassini spacecraft takes an angled view toward Saturn, showing the southern reaches of the planet with the rings on a dramatic diagonal.

The moon Enceladus (313 miles, or 504 kilometers across) appears as a small, bright speck in the lower left of the image.

Cassini Saturn 5

Strong Jet in False Colors

A particularly strong jet stream churns through Saturn’s northern hemisphere in this false-color view from NASA’s Cassini spacecraft.

Cassini Saturn 6

Saturn’s North Pole, Wide View

This image from NASA’s Cassini mission was taken on Nov. 27, 2012, with Cassini’s wide-angle imaging camera. The camera was pointing toward Saturn from approximately 233,742 miles (376,171 kilometers) away.

Storm Tail in False Color

This false-color mosaic from NASA’s Cassini spacecraft shows the tail of Saturn’s huge northern storm.

Cassini Saturn 8

Wispy Dione

This raw image of Saturn’s moon Dione taken by NASA’s Cassini spacecraft shows the fractured region known as “wispy terrain.” The image was obtained on Dec. 20, 2010, from a distance of about 107,000 kilometers (66,000 miles).

The Science of Productivity

December 17th, 2012 | Brain

 

Productivity

Everyone would appreciate a little more productivity in their lives, and the short video above gives you a few tips to make that possible.  I remember reading about the study habits of world class musicians a while back.  Someone did a pretty extensive study comparing the best violinists in a school to the rest of the students, and like the video states, it was found that the best musicians didn’t study any longer but rather more effectively.  The best students attacked the most challenging musical sequences while other students focused on the easier portions of the songs.  I have a feeling that this may be a common trait among all successful people.

In the world of Facebook, Reddit, Twitter, and Instagram it can be a bit difficult to maintain focus and accomplish goals.  To increase your productivity, focus on these main points from the video above:

  • Get Started!
  • Don’t rely on will power, Stick to a plan
  • Break up large projects into smaller, achievable tasks
  • Make deadlines
  • Take planned study breaks
  • Stop Multitasking!

I have begun making nightly lists for the next day’s tasks, and I’ve found this to greatly increase my productivity.  Maybe it can help you too.

The Progression of a Burn

December 13th, 2012 | Brain

The human body has a truly amazing capacity to heal itself.  Below, you will find one such case – the dorsal side of this unlucky left hand was burned in a kitchen fire.

In the quotes below each picture, you’ll find notes from the Redditor who suffered through the experience.

Warning: the hand burn images can be a bit graphic! However, it’s fascinating to witness how the skin heals from day to day.  Enjoy!

Hand Burn

“Burn Day 1 – this is the only day that my hand actually hurt. It started to swell and blister.”

Hand Burn

“Burn Day 2 – I was keeping it wrapped in gauze and using ointment. No pain at all, just this terrifying blister.”

This signifies to me that the burn is pretty deep.  The fact that he feels no pain at all implies nerve damage.

Hand Burn

“Burn Day 3 – this is the day I finally went to a walk in clinic. The doctor looked at it for 45 seconds, told me to put bacitracin on it, and charged me $113. ‘Murica.”

Burn Day 4 – Blister Grows, Incredible

“Burn Day 5 – it finally popped while I was sleeping, but I kept my hand wrapped in gauze, so no mess.”

“Burn Day 7 – I thought it was looking pretty good.”

“Burn Day 8 – the dead layer has sloughed off. Oh god, the shiny new skin. Fun fact: If I held my hand above my head, every time my heart beat, that whole area would flash bright red.”

Burn Day 9 – Continued healing

“This is my hand a year and a half later. There is just a little discoloration on my knuckles and a barely visible oval on the back of my hand between my thumb and index finger.”

To determine the scale of a burn, you must know the depth of injury to the dermis.

A 1st degree burn implies that the burn only involves the outermost layer of skin called the epidermis.  These burns are usually red, dry, painful and heal in about a week.

2nd degree burns extend into the next layer of skin, the dermis.  These involve blistering and are usually painful and may result in some scarring.  Infection starts to become a concern.

3rd degree burns are burns that extend through the FULL thickness of the skin.  These are stiff, white/brown, painless and often lead to scarring and possibly amputation.

4th degree burns are as nasty as it gets.  They extends all the way through skin, subcutaneous tissue and into underlying muscle and bone.  Click here if you have a strong stomach.

I’d say the hand burn above is a pretty bad 2nd degree burn (blistering) with some elements of 3rd degree due to the nerve damage.

Pale Blue Dot Animated Video

December 10th, 2012 | Space

Pale Blue Dot by Carl Sagan

This is a new animated video of Carl Sagan’s “Pale Blue Dot” speech by Joel Somerfield (from the animation studio, Order, in East London).  It’s a moving speech and the style of the video does it justice. I’m not sure it beats out Reid Gower’s video of “The Frontier is Everywhere,” but I still enjoyed it quite a bit. It should be said, however, that a few of us are living in space right now.
