How could you miss a moose in broad daylight? Easy to miss, if you’re not looking with thought.

Do moose think about coming at you from out of the sun?

If you’re looking for that particular moose, the Seedskadee National Wildlife Refuge is near Green River, Wyoming.

May 23 is World Turtle Day.  In fact, this is the 14th World Turtle Day.

No grand pronouncements from Congress, probably — American Tortoise Rescue picked a day, and that was that.  Their press release for 2014:

American Tortoise Rescue Celebrates World Turtle Day 2014 on May 23rd

Malibu, CA – May 14, 2014 –  American Tortoise Rescue (ATR) (www.tortoise.com), a nonprofit organization established in 1990 for the protection of all species of tortoise and turtle, is sponsoring its 14th annual World Turtle Day on May 23rd.  The day was created as an observance to help people celebrate and protect turtles and tortoises and their disappearing habitats around the world.  Susan Tellem and Marshall Thompson, founders of ATR, advocate humane treatment of all animals, including reptiles.  Since 1990, ATR has placed about 3,000 tortoises and turtles in caring homes.  ATR assists law enforcement when undersized or endangered turtles are confiscated and provides helpful information and referrals to persons with sick, neglected or abandoned turtles.

“We launched World Turtle Day to increase respect and knowledge for the world’s oldest creatures,” said Tellem. “These gentle animals have been around for 200 million years, yet they are rapidly disappearing as a result of smuggling, the exotic food industry, habitat destruction, global warming and the cruel pet trade,” says Tellem. “We are seeing smaller turtles coming into the rescue meaning that older adults are disappearing from the wild thanks to the pet trade, and the breeding stock is drastically reduced.  It is a very sad time for turtles and tortoises of the world.”  (See slide show here.)

Tellem added, “We are thrilled to learn that organizations and individuals throughout the world now are observing World Turtle Day, including those in Pakistan, Borneo, India, Australia, the UK and many other countries.” She recommends that adults and children do a few small things that can help to save turtles and tortoises for future generations:

  • Never buy a turtle or tortoise from a pet shop as it increases demand from the wild.
  • Never remove turtles or tortoises from the wild unless they are sick or injured.
  • If a tortoise is crossing a busy highway, pick it up and send it in the same direction it was going – if you try to make it go back, it will turn right around again.
  • Write letters to legislators asking them to keep sensitive habitat preserved or closed to off road vehicles, and to prevent off shore drilling that can lead to endangered sea turtle deaths.
  • Report cruelty or illegal sales of turtles and tortoises to your local animal control shelter.
  • Report the use of tiny turtles as prizes at carnivals and other events.  It’s illegal.
  • Report the sale of any turtle or tortoise of any kind less than four inches.  This is illegal to buy and sell them throughout the U.S.

“Our ultimate goal is to stop the illegal trade in turtles and tortoises around the world.  Our first priority here in the U.S. is to ask pet stores and reptile shows to stop the sale of hatchling tortoises and turtles without proper information for the buyer,” says Thompson.  “For example, many people buy sulcata tortoises as an impulse buy because they are so adorable when they are tiny.  The breeders and pet stores frequently do not tell the buyers that this tortoise can grow to 100 pounds or more and needs constant heat throughout the year since they do not hibernate.”

He added, “We also need to educate people and schools about the real risk of contracting salmonella from water turtles.  Wash your hands thoroughly every time you touch a turtle or its water, and do not bring turtles into homes where children are under the age of 12.”

Identifying poison ivy

May 22, 2014

This may become a series.

Found a good infographic today, on how to identify poison ivy — the bane of every Boy Scout and Scouter west of the Mississippi, and east of the Mississippi, too.

From TreksInTheWild.com, via Daily Infographic

From TreksInTheWild.com, via Daily Infographic

Poison ivy leaves turn a beautiful scarlet in the fall.  This beauty prompted English ship captains dropping off colonists in New England to take the potted vines back to England.

It is my experience that, while everyone can become allergic and react to poison ivy, no one reacts on first serious exposure. If you’re in the woods, it’s good to know what this stuff is, and avoid it.

If you’re exposed, wash it off.  Wash your clothes with some sort of oxidant (oxygen bleach for colors, or chlorine bleach if you don’t care); I use a 3:1 solution, water to chlorine bleach, to shower with after serious exposure.  The active chemical, urushiol, remains active until it is reacted chemically or by ultraviolet light — and so a young Scout who gets some ivy sap under his fingernails can continue to spread the exposure everywhere he scratches, until his hands are really washed clean.

Study the poster, learn to identify the stuff.  There’s a lot more to say.


Milky Way in Navajoland: YIKÁÍSDÁHÁ

Phil Plait’s column/blog at Slate, Bad Astronomy, put me on to this one.  Wow.

You can see it at Vimeo, and read a lot more about the making of the film.

YIKÁÍSDÁHÁ (Navajo for Milky Way or “That Which Awaits the Dawn”)

Phil wrote:

And that they do. The Milky Way is the star of the show; the galactic bulge, disk, and dark fingers of vast dust lanes as clear as if this were taken from space. Well, sort of; I was impressed by the mix of clouds and sky, to be honest. The contrast was interesting, and it’s rather amazing the Milky Way could stand out so clearly above the cloud line.

One thing I want to point out specifically: At 2:10 in, a meteor flashes and leaves behind a curling wisp of what looks like smoke. This is called a persistent train, the vaporized remains of the meteoroid itself, and can glow for several minutes. The upper level winds from 60–100 km above Earth’s surface are what blow it into those curlicues.

We are poorer because Farley Mowat is dead

May 9, 2014

Farley Mowat died May 7.  He was 92.

The man was such a champion of the environment that he was, at one time in the 1980s, prevented from traveling to the U.S., because he was listed with Immigration as a potential terrorist.  He may be the only person so listed, simply for urging that we stop killing animals.

Mowat was unsurpassed as a pure curmudgeon in favor of the wild, wild animals, wilderness, and environmental protection.  He was a story teller above all, understanding completely the powerful role that stories play in moving government policies — which his books frequently did.  His first works, on indigenous peoples in Canada’s far north, wrought significant changes in Canada’s policies towards those now known as First Nations.  When his signature book, Never Cry Wolf, was translated into Russian, Russia prohibited hunting wolves.

From the Washington Post obit notice:

“I keep my optimism alive and revitalized by accepting the fact that we are a bad species, and probably haven’t got much time here,” he told The Washington Post in 1994, “and it’s not going to break my heart when Homo sap wanders offstage.”

Then he added, “Wanna get some more coffee?”

Barry Goldwater might say that extremism in pursuit of noble conservation is no vice.  Mowat wouldn’t care what Goldwater thought.

So long, Farley Mowat.

Cross seas: Nature, or design?

April 16, 2014

Here’s just exactly the sort of thing that happens in nature that drives creationists nuts.  How could this happen without God personally working to confuse and/or delight the photographer?  Not to mention the physicist and mathematician.

Where? Somewhere in France, one might gather from the flag on the structure (lighthouse?).

Turns out to be a Wikipedia photo, with this intriguing caption:

Crossing swells, consisting of near-cnoidal wave trains. Photo taken from Phares des Baleines (Whale Lighthouse) at the western point of Île de Ré (Isle of Rhé), France, in the Atlantic Ocean. The interaction of such near-solitons in shallow water may be modeled through the Kadomtsev–Petviashvili equation.

Oh, you remember that one, don’t you?  The Kadomtsev–Petviashvili equation?

At least we confirmed it was taken in France.

They do everything differently in France, don’t they?

Update:Got an e-mail suggestion that I include the equation itself.  You may certainly click to Wikipedia to find it; here’s what it says over there:

In mathematics and physics, the Kadomtsev–Petviashvili equation – or KP equation, named after Boris Borisovich Kadomtsev and Vladimir Iosifovich Petviashvili – is a partial differential equation to describe nonlinearwave motion. The KP equation is usually written as:

\displaystyle \partial_x(\partial_t u+u \partial_x u+\epsilon^2\partial_{xxx}u)+\lambda\partial_{yy}u=0

where \lambda=\pm 1. The above form shows that the KP equation is a generalization to two spatial dimensions, x and y, of the one-dimensional Korteweg–de Vries (KdV) equation. To be physically meaningful, the wave propagation direction has to be not-too-far from the x direction, i.e. with only slow variations of solutions in the y direction.

Like the KdV equation, the KP equation is completely integrable. It can also be solved using the inverse scattering transform much like the nonlinear Schrödinger equation.

Certainly the longest equation ever published at Millard Fillmore’s Bathtub.
