Must See This

Proverbs 7

I have always wondered if they were on top of it ?

Poles

I don’t know who the Poles are.  I’m assuming that they’re people that live around the North Pole and South Pole.

Anthropologists were right. 😜

Fluids Round-Up

New year, new (or renewed) experiments. This is the fluids round-up, where I collect cool fluids-related links, articles, etc. that deserve a look. Without further ado:

Above is a new music video from the Julia Set Collection, featuring all non-CGI, fluids-based visuals. I spy soap films, vibrating liquids, and lots of cool effects with reflection and refraction. We featured some of their previous work, too. 

The Atlantic has a great piece about jellyfish and how they might just change our understanding of efficient swimming.

Check out the wild shape-shifting of these drops of oil during freezing and learn about the plastic crystal phase some matter experiences.

Nature has an interesting article on active matter, an intersection of physics and biology exploring how matter self-organizes, whether at the level of cells or the flocking of birds. (submitted by 1307phaezr)

Ever wonder what the human face looks like in 457 mph winds? Wonder no more.

Gizmodo has a beautiful set of macro photos of snowflakes. Interested in how snowflakes form and why there are so many different shapes? We’ve got you covered.

Wired takes a look at the surf forecaster who predicts the waves for the Mavericks big-wave competition.

Robert Krulwich (and friends) took a closer look at our fish in microgravity. Here’s what they learned!

When I was a child , my mother taught me the Lord's prayer's. That was all I needed to know.

photos of the april 2010 volcanic eruptions in eyjafjallajokull, iceland, which produced a dirty thunderstorm. the phenomenon is yet to be explained by science, as the source of the lightning (or the specific mechanism by which particles of differing charges are separated in the ash cloud) continues to be debated.

@crazywhenisleep is referencing this gif that alternates between these two images, one in visible light and one in infrared, asking which is the one in infrared:

It’s the second one. 

FUN SIDE NOTE

“infrared” is a wavelength of light just below what humans can see. Red is the color we perceive when we see the longest wavelength we can, and ‘infra’ means ‘below.’ Hence, “infrared”–“below red”

FUN SIDE NOTE 2:

In movies (or maybe in real life?) you’ve probably seen strip clubs depicted as having red lights. This isn’t an accident, and they often use red light; as the wavelength of light gets longer, it is harder and harder for humans to see detail. Further, we can’t see as well in red light since we didn’t evolve to see in such conditions. Thus, red light effectively “covers up” small defects and marks on your skin. 

Strip clubs, and other such places, use that color light because of this.
