∆x∆p ≥ h/4π

... All the [ Uncertainty ] Principle actually says, in its entirety, is:

∆x∆p ≥ h/4π

That’s it.

The next great crash will be ecological...

The next great crash will be ecological - and nature doesn't do bailouts

Posted by Johann Hari 

2 days ago

Why are the world's governments bothering? Why are they jetting to Cancun next week to discuss what to do now about global warming? The vogue has passed. The fad has faded. Global warming is yesterday's apocalypse. Didn't somebody leak an email that showed it was all made up? Doesn't it sometimes snow in the winter? Didn't Al Gore get fat, or molest a masseur, or something?

Alas, the biosphere doesn't read Vogue. Nobody thought to tell it that global warming is so 2007. All it knows is three facts. 2010 is globally the hottest year since records began. 2010 is the year humanity's emissions of planet-warming gases reached its highest level ever. And exactly as the climate scientists predicted, we are seeing a rapid increase in catastrophic weather events, from the choking of Moscow by gigantic unprecedented forest fires to the drowning of one quarter of Pakistan.

Praying Mantis - Pseudocreobotra wahlbergii

all Creatures [great and small]

jacquesofalltrades:

Praying Mantis - Pseudocreobotra wahlbergii. This beautiful whalbergii evolved through two of its nymph-stages on the Barberton Daisy at left, surviving because of its bright color which blended so well with the flower. Towards the end of its growth into an adult, it became a little more adventurous (but not much more) as pictured here. Once it had shed the layer in this picture, it became a fully-fledged adult, and departed after about two weeks. Total stay in this tiny ecosystem was approximately six weeks.

Duke of Wellington statue, original oil painting

This is an oil on board painting, approximately 6x6 in (15x15 cm) large, completed in 2010 (drying time - 7 days from the day of this post), shipped without a frame in a foam lined manilla envelope. Remember that colours may look slightly different in person, but usually for the better!

a baby La Plata river dolphin

Richard Tesore, head of the NGO Rescate Fauna Marina, feeds a baby La Plata river dolphin in Piriapolis, 62 miles east of Montevideo, Uruguay. The dolphin, which was found on the beach in the city four days ago, is recovering at the reserve from injuries believed to have been caused by a fishing net.

Got Dew?

Food! Any food in there?

Cadbury and Mocca, a couple of cheeky wombats at a wildlife centre in Melbourne, spot a camera and make a beeline for it before clambering all over it and sticking their noses in every nook and cranny…

Jaba the Frog

thesophie:mabelmoments:

A mouse looks out from the jaws of a huge voracious African bullfrog. These carnivorous amphibians have an aggressive temper and can jump 3.5 metres. The huge predatory frogs sit and wait for animals to pass by. They are stimulated by movement and will lunge at pretty much anything that comes within range, including this unlucky mouse.

The same octopus...

The best way to spot an octopus on the reef is by looking out, rather than looking down.  Octopuses like to survey their territory, and when they’re resting they sit on the tops of ledges, outcroppings, etc. in order to see everything around them.  An octopus can see you coming from a long way away, so if you’re swimming along and just looking down into holes in the reef, the octopus’ll be long gone by the time you get there. The best way to find one is to swim slowly and look out at the highest points around you.  When an octopus sees you it’ll usually change color and drop down quickly, immediately giving away its position.  It’s kind of like hide-and-seek, except the octopuses don’t usually want to be found, and rather than laughing or losing gracefully, they just shoot water at you with their siphon. I found this guy in about 5 feet of water at Hanauma Bay yesterday trying to look like a rock.

The same octopus 30 seconds later...

This is the same octopus about 30 seconds later. One of the coolest things about the octopus is its ability to change color.  All Cephalopods can do this, but octopuses are by far the best at it.  They have 4 different tools which they use to change color and brightness, these are Chromatophores, Iridophores, Leucophores, and Bioluminescence, which can be activated as a chemical reaction within the octopus’ skin cells. In basic terms, the octopus possesses all the colors in its skin already.  To change, it reveals certain colors by unfolding microscopic sacks in its skin and keeping others tightly shut.  It’s a very complicated, detailed process that happens in several thousandths of a second. If you want the nitty gritty on it, some great info can be found in this PDF on The Cephalopod Page.

Some politicians don't want you to vote!

Voting, misunderstood

 

This year, fewer than 40% of voting age Americans will actually vote.

A serious glitch in self-marketing, I think.

If you don't vote because you're trying to teach politicians a lesson, you're tragically misguided in your strategy. The very politicians you're trying to send a message to don't want you to vote. Since 1960, voting turnouts in mid-term elections are down significantly, and there's one reason: because of TV advertising.

Political TV advertising is designed to do only one thing: suppress the turnout of the opponent's supporters. If the TV ads can turn you off enough not to vote ("they're all bums") then their strategy has succeeded.
