## If great scientists had logos . . .

August 11, 2014

These are quite creative.  I wonder who invented them?

Other possibilities?

Maybe:

Edison’s logo?

## Family stickers on the van . . . too far

June 6, 2014

It was spotted in Utah, of course (note the mountains in the background).

Yeah, we had that family living next door to us for a while.

Look closely, it appears not to be a claim for a polygamous family . . . oy.  Surely, it is a joke.

Maybe it’s a kindergarten teacher who thinks all students are her kids, or his kids. Maybe the driver just wants to start conversation, or convulsions of laughter.

## Signs of life: Endangered squirrels

May 13, 2014

From jbendery (Jennifer Bendery) — I learned today that there are endangered squirrels, and apparently they have ginormous tails. (h/t @kate_sheppard) pic.twitter.com/Uu4QxiDa5M

A lot of punchlines possible, e.g., ‘if the squirrels weren’t slow, maybe they wouldn’t be endangered.’

Still a rather unique sign, no?

I wonder where it is?  This sign marks habitat in the Blackwater National Wildlife Refuge  in Maryland for the Delmarva fox squirrel.

Update:  Well, maybe not wholly unique; World Wildlife Fund has this one — again, without a note about location.

## Feynman Day comes Sunday; celebrate with your mother, and fly the flag!

May 9, 2014

No, we’re not joking.

May 11 is the anniversary of the birth of Richard Feynman (born 1918, died 1988).

Richard Feynman. Borrowed from Luciano’s Tumblr, LikeaPhysicist

In 2014, his birthday falls on Sunday, Mothers Day.  Mothers Day is one of the designated-by-law days to fly the U.S. flag — so fly your flag!  You can tell your mother it’s for her — but it’s also for Richard Feynman.

Why Feynman Day?  To celebrate invention, physics, interesting characters, and that essential, American quality of je ne sais quoi.

In addition to his winning the Nobel Prize for Quantum Electrodynamics (QED), Feynman popularized the critique of science and other enterprises with what we now call Cargo Cult science, or education, or whatever, where people follow the dance steps, but without the rhythm and music.

Those two things alone would make him a remarkable man.  But, like a product offered for $19.95 as a good buy in a 2:00 a.m. infomercial, with Feynman, there’s more. With Feynman, there is always more. I got alerted to Feynman in the first days of the old Quality Paperback Book Club, when they featured his new memoir, Surely You’re Joking, Mr. Feynman! QPBC was hot on the book, and with a title like that, how could I resist? When I got the book a week or so later, I read it within two days, while attending law school and working full time. I remember Feynman. Norton published the book — and their description, alone, should make you want to read it: A New York Times bestseller—the outrageous exploits of one of this century’s greatest scientific minds and a legendary American original. In this phenomenal national bestseller, the Nobel Prize­-winning physicist Richard P. Feynman recounts in his inimitable voice his adventures trading ideas on atomic physics with Einstein and Bohr and ideas on gambling with Nick the Greek, painting a naked female toreador, accompanying a ballet on his bongo drums and much else of an eyebrow-raising and hilarious nature. All true, and that’s not even the half of the outrageousness, all done with great good humor, about a life lived in great good humor through what should have been a memorable age, but often was just terrifying. I think sometimes that Feynman’s calm, alone, borne of that great good humor and insatiable curiosity, may have gotten us through the birth of the atomic age and the Cold War. Feynman was a giant, and we don’t revere him enough. Consider: • Feynman’s high school sweetheart, Arlene, came down with tuberculosis. He married her, and took her with him to New Mexico to make the atom bombs. The stories of her confinement to a hospital, and the laborious trekking he had to make between Los Alamos and her bedside in Santa Fe, are touching, and heartbreaking. It is one of the great love stories of the 20th century, certainly, and perhaps for all time. It also provided the title for his second memoir, What Do You Care What Other People Think? • Every single, college-age man should read Feynman’s stories of how to date, and how to seduce women. His approach was unique, and endeared him to women — in legend, to many women. Feynman’s dating must have been part of the inspiration for the comedy series, “Big Bang Theory.” Feynman’s stories are better. (Heck, it’s even the subject of a popular, classic XKCD comic — probably only Feynman and Einstein among Nobel-winning physicists have made so much money for so many cartoonists.) US postage stamp featuring Richard Feynman • Yeah, he’s already been featured on a postage stamp, see at right. That’s not good enough for Feynman, though — the U.S. Postal Service created a special cancellation stamp for Feynman, featuring a version of his Feynman Diagrams. A special postal cancel was authorized by the USPS (United States Postal Service) to honor the 80th birthday of Richard Feynman. This cancel was used in Lake Worth, Florida. For this special day the post office was renamed “Feynman Station.” The Feynman Diagram used for the postal cancel on this envelope depicts what is known as a “bubble process.” It shows a high energy particle, for example, a cosmic ray (a) from a distant supernova, which emits a high energy photon, for example, a gamma ray (b). The photon, in turn, creates a particle (c) and an anti-particle (d) that exists for a brief moment and then recombines. As Feynman liked to point out, an anti-particle is the same thing as a particle with negative energy traveling backward in time (which is why the arrow at (d) points backwards, i.e. to the left). So you could say the photon created only one particle that, at first, traveled forward in time (the bottom semi-circle) and then reversed and went back in time (the top semi-circle) and annihilated itself! By inventing diagrams like this, Richard Feynman made it much easier to understand what is going on in the interactions between sub-atomic particles without getting lost in tremendous amounts of tedious math • Working at Los Alamos on the Manhattan Project, Feynman developed a keen appreciation for bureaucracy and all its follies. His vexations for the security managers are also legendary. Here’s a quick version of one story — he asked friends and family to write to him in code, but to not include a key to the code, so he’d have to crack the code to read the letter. Feynman could do it, but the security people couldn’t. Hilarity ensued. • Feynman developed a love for the still-relatively unknown, landlocked Asian nation of Tannu Tuva. It’s just the sort of place to appeal to a character like Feynman — so obscure most atlases didn’t, and don’t, show it at all — seemingly consumed by the Soviet Union, but held in a special status. Home of throat singing — and almost impossible to get to. During the Cold War, Feynman struck up correspondence with people in Tuva, to the concern of Soviet and American intelligence agencies, who seemed not to understand someone might do such thing out of curiosity. Feynman hoped to travel there to visit new friends, but his final bouts of cancer took him before it was possible. Tuva, famous among philatelists only, perhaps, honored Feynman with postage stamps and postcards. • Just try to find a photo of Feynman not smiling. The man was a joy to be around, for most people, most of the time. • Quantum electro dynamics? No, I can’t explain it, either — but his work had a lot to do with how particles wobble. I remember that because, according to Feynman, he got the inspiration for the work for which he won the Nobel while spinning plates, like a Chinese acrobat on the Ed Sullivan Show, to the delight of students in the Cornell University cafeteria, and the shock and horror of the food service people. Who else has yet confessed to such an inspiration for a Nobel? There’s more — a lot more. Feynman outlined our current generation of computer memory devices — in 1959. No, he didn’t patent the idea. He did patent an idea for a nuclear-powered spacecraft. Another delightful story. Feynman was featured in print and broadcast ads for Apple — not one, but two (did anyone else get that honor from Apple?). “Think Different.” This is one of Apple Computer’s most successful advertising campaigns. The theme of the campaign is one that celebrates figures in history who changed the world by thinking differently. Richard Feynman was among the chosen figures. Feynman served on the board that approved science books for the California school system — his stories of that work will shock some, but it will make others shake their heads as they recognize the current crop of cargo-cultists and political bullies who dominate textbook approval processes, knowing nothing at all about what they are doing, or why. No, I didn’t forget his brilliant work on the commission that studied the Challenger disaster, for NASA. There’s so much stuff to glorify! In history, Feynman should be remembered much as we remember Thomas Jefferson, as a renaissance man in his time, a man who put great intellect to great work for his nation and all humanity. The second Apple ad featuring Richard Feynman. An excerpt from Apple Computer’s campaign commercial: “Here’s to the crazy ones, the misfits, the rebels, the troublemakers, the round pegs in the square holes, the ones who see things differently. They’re not fond of rules and they have no respect for the status quo. You can quote them, disagree with them, glorify or vilify them… about the only thing you can’t do is ignore them, because they change things, they push the human race forward; and while some may see them as the crazy ones, we see genius, because the people who are crazy enough to think they can change the world are the ones who do.” The sages say we shouldn’t have regrets, but I do have one. When the Challenger Commission was meeting in Washington, D.C., I was working on another commission up the street. I knew Feynman was ill, but our work was important, and we’d heard his disease was in remission. I didn’t goof off a day and go to any of the hearings to see him, to get an autograph, to meet the man. I though I’d have other opportunities to do that. Now I regret not having met him in person. In print, and in film, I know him well. In our family, reading Feynman is something everybody does. Feynman’s memoir was one of the last books I read to our son, Kenny, as he was growing up, and growing into reading on his own. Even reading about Feynman, together, was an adventure. Our son, James, took us into the real physics of Feynman, and though I struggle with it more than James, we still read Feynman, for humor, and physics. What would be appropriate ways to mark Feynman’s birth? At some future date, I hope we’ll have public readings of his books, showings of the documentaries about him, recreations of his lectures, perhaps. And then everyone can get in a circle, beating drums and singing about getting some orange juice, before sending postcards to our friends in Tuva. Richard Feynman, we still need you, and miss you dearly. Tuva’s capital is the delightfully-named Kyzyl. From this map, can you figure out where Tuva is, or how to get there — without Google, or Bing? Tuva postcard, in honor of Richard Feynman — who loved to drum. There will always be “More” about Richard Feynman, if we’re lucky: ## Have a great Feynman Day! Much of this is an encore post. ## Insta-Millard: “Not available on the App Store” — real child’s play May 9, 2014 Found on Twitter: Deep thoughts on Twitter, about children, childhood, recess and play. https://twitter.com/IntThings/status/464766923201576960 ## Insta-Millard: The vultures in Detroit’s bankruptcy May 9, 2014 Maybe there’s a John Waters movie in the story. Jerry Vile strikes again. The artist (and volunteers) stuck about 100 plastic lawn flamingos painted to look like vultures — one can imagine Vile lovingly glueing on the feathers — on the front lawn of the Detroit Institute of Arts. A banner was also erected, reading “Happy Bankruptcy: You’re Getting Flocked! Vultures by the Scads, LLC.” It’s Vile’s latest prank that targets Detroit’s bankruptcy and the threat of selling the DIA’s artwork to appease “creditor vultures.” Within the past year the artist has put out an ad for Detroit’s liquidation in Metro Times, rolled out an oversized can of Crisco in front of the Joe Louis fist, and placed price tags on public art throughout the city. The only statement the artist has made so far about the vultures is a post on his Facebook page that says, “Sssssshhhhhhhh. Can’t wait to get a look at Beal’s face when he pulls up to work tomorrow.” Negotiations are ongoing in regard to an$816 million so-called “grand bargain” — funded by numerous foundations, the state, and the DIA itself — that would spin the DIA into a new nonprofit and prevent the sale of any city-owned art. Meanwhile, Lansing is setting up a board that could oversee Detroit’s pensions and finances for 20 years, and also potentially appropriate \$194.8 million from the state’s rainy day fund toward Detroit’s bankruptcy.

## 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.

Photo from the Twitter feed of Science Porn: “Go home waves you’re drunk. This is called cross sea btw pic.twitter.com/5Cv1UUo8QX”

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.
