How to celebrate the 100th anniversary of the birth of Richard Feynman?

Here’s what others say and do.

 

Paul Halpern wrote a recent book on Feynma

There are those who look critically at Feynman’s life, and recognize his flaws — as Feynman did, too. This is an interesting thread.

 


May 11 is Feynman Day! How to celebrate? (It’s his centenary!)

May 8, 2018

May 11, 2018, is the 100th anniversary of the birth of Richard Feynman (born 1918, died 1988).

Most Feynman fans are celebrating through the entire year — appropriately, for a man so much larger than life and unable to be constrained after death.

We should mark the actual day, I think. It would be a good thing to celebrate science on May 11 in his honor, I think. And, there are lots of other good ways to commemorate a great guy.

Richard Feynman

Feynman’s birthday falls on Statehood Day for Minnesota.  You can fly your flag for both causes, if you wish, Minnesota’s statehood AND Feynman’s birthday.  No proclamation will issue from the White House, but you can fly your flag any day.

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 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. Women should read it, too, to know what’s happening. Consent is necessary. 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.)

  • 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.

    USPS authorized a special postal cancel (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.”
    Feynman Commemorative Cancel Feynman Diagram

    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 electrodynamics?  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 in an Apple ad

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. Image from the Feynman Group.

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.

Feynman's second Apple ad

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 thought 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?

Historic Deltoid: Indur Goklany on DDT, corrections from Tim Lambert

April 10, 2018

I’ll have to beg forgiveness from Tim Lambert, but in the interest of accuracy and good history, I have captured below the post Tim Lambert had on the old Deltoid blog (at the Seed Science Blogs site), dealing with Indur Goklany’s errors on DDT.

A bit of other history: Anthony Watts despises my posts (me, too, probably) and I am banned from his site for various sins including calling him out for suggesting Rachel Carson and President John F. Kennedy had more than an occasional handshake personal relationship (a bizarre charge Christopher Monckton repeats and exaggerates on in slightly different ways). Watts and I disagree on what we should regard as facts; I take the old collegiate debate and Scout Law positions, he sides with the Heartland Institute parody/comedy/hoax troupe.

Watts was having none of my corrections. Tim Lambert, who has researched this particular area of pro-DDT hoaxing more than anyone else, was kind enough to respond.

This is borrowed from the Internet Archive’s Wayback Machine, until, and then maybe a supplement to, the reappearance of Deltoid’s archives at the new site. As of April 10, 2018, I have not checked the links. If links don’t work, please tell me in comments, and I’ll work to get a new link to the old information where possible.

You should also know that Sri Lanka today is certified to be malaria-free, without DDT.

Below, Tim Lambert’s post on Indur Goklany’s errors about DDT history:

 

Indur Goklany, DDT and Malaria

More »

Ed Darrell points to a WUWT post by Indur Goklany which promotes the use of DDT to fight malaria instead of more effective measures. As with most of the DDT promoters, Goklany carefully avoids mentioning the way mosquitoes evolve resistance to insecticides. For example, here’s what he has on Sri Lanka:

For instance, malaria incidences in Sri Lanka (Ceylon) dropped from 2.8 million in the 1940s to less than 20 in 1963 (WHO 1999a, Whelan 1992). DDT spraying was stopped in 1964, and by 1969 the number of cases had grown to 2.5 million.

Now compare this with what really happened in Sri Lanka:

With widespread resistance of A. culicifacies to DDT, malathion spraying was introduced in 1975 in areas of P.falciparum transmission affording protection to nearly one million people. Towards the end of 1976 DDT spraying was completely discontinued and during 1977 exclusively malathion was used as an adulticide.

i-888470655207729222fb0f61fe5fa18a-oth_mal_cases_srl60-08.png

Note that the scale for malaria cases is logarithmic, so there was a factor of ten reduction in the number of cases in a few years after DDT spraying was discontinued.

The misinformation about DDT and malaria that Goklany spreads is harmful and could kill people. DDT still has a place in the fight against malaria (because of insecticide resistance we need as many different insecticides as possible), but there are more effective means available, and by trying to undercut the use of the best methods for fighting malaria, Goklany will be responsible for people dying from malaria.

Now, is it possible that the comments will copy as well as the blog post? There are some good ones in there.

Here’s a try at copying the comments, below the fold.

Mount Rushmore, as a tribute to a profession

April 9, 2018

It’s sort of a game: Which four people should be ensconced in much larger-than-life stone sculptures on the side of a mountain (preferably an ugly mountain that is not sacred to any First Nation, but I digress)?

Found a puzzle slanted toward a Rushmore of science, featuring Einstein, Curie, Newton and Darwin.

Puzzle created by Discover, honoring four greats of science.

You can purchase the puzzle at MyScienceShop.com.

We’ve featured the Rushmore of Chicago blues here before, Mount Bluesmore, featured in Buddy Guy’s Legends bar and music venue. I understand the painting moved when Legends moved.

Mount Bluesmore, in the old Legends venue: Muddy Waters, Sonny Boy Williamson, Little Walter, and Howlin' Wolf.

Heck, this could be a great game: Name four people in any profession, art, field of endeavor, who should be featured on a Mount Rushmore-style monument. Above we’ve got science and Chicago blues. On the real Mount Rushmore, we’ve got the Rushmore of U.S. Presidents.

The real Rushmore, in South Dakota. It features Presidents Washington, Jefferson, Teddy Roosevelt and Lincoln, left to right. National Park Service image.

What other monuments could we have? Painting? Picasso and Rembrandt . . . but there are so many.

Renaissance painting. Abstract painting. Landscapes, portrait painters. Architects. Rock musicians. Classical musicians. Baseball. Football. American football. Fiction authors. Engineers. Women scientists. Tuskegee airmen (that would be tough; every one of them deserve it).

Who do you nominate, for what field?  Put nominations in comments. Include pictures if you find one.

‘DDT has become harmless to mosquitoes today’

March 29, 2018

From India today, not news to anyone who follows the fight against malaria, and the fight to save a part of the planet to preserve human life.

DDT resistance prompted India to agree to stop production of DDT by 2020 — the last DDT factory remaining. India’s disease fighters tell of frustration trying to control malaria, because abuse of DDT has bred DDT resistant and immune mosquitoes. This is not news.

But India Today has a news hole to fill, and the continuing crises of vector-borne diseases force public health agencies to turn to “fourth generation” pesticides, as insects are now resistant to DDT and malathion.

The story out of New Delhi on March 13 almost adds some poetry to the issue. I repeat the story from India Today in full, partly because I love the lilt of Indian English, and because it tells the story of continuing attempts to get ahead of pesticide resistance in pests, attempts that just don’t seem to be doing the job.

Delhi’s civic agencies asked to use fourth generation pesticides to kill chemical-resistant insects

Pesticides such as DDT and malathion, which were once super weapons in the fight against mosquitoes, now seem to have become harmless perfume-like sprays for the blood-sucking parasites.

Scientists at the National Vector Borne Disease Control Programme (NVBDCP), Delhi which is the central nodal agency for prevention of diseases like malaria, dengue, filariasis, kala-azar, Japanese encephalitis and chikungunya, etc, in India has now recommended municipalities in the Capital and other parts of the country to shift to the 4th generation of pesticides that is also the last in the row.

These constitute certain bio-larvicides and insect growth regulators that stop the synthesis of critical hormones in mosquito larvae to prevent them from becoming adult. Only after attaining maturity, do the female Anopheles and Aedes Aegypti mosquitoes suck blood to get protein nutrition to lay eggs.

Scientists explain that the first generation of pesticides was DDT, used since World War II on soldiers in 1940s up till now, as its a powerful poison against mosquitoes. Later, its environmental effects, specifically on birds like vultures, reduced its usage globally.

Then came malathion, which had to be applied in huge quantities, paving the way for 3rdgeneration pesticides like synthetic pyrethroids and temephos. But with reports of mosquitoes developing tolerance towards all of these gradually, scientists are now recommending mixed and increased usage of the fourth generation of pesticides that is also the last line of defence in this class.

Experiments are still going on with genetically modified mosquitoes and introducing batches of mosquitoes injected with wolbachia bacteria in the wild to produce sterile eggs. A senior scientist with the NVBDCP, Civil Lines, said, Just like humans develop resistance towards antibiotics, mosquitoes have also evolved over the past 20-30 years to grow natural defence against DDT, malathion, etc. We are still using these two in virgin areas like forests of northeast India, Odisha, etc. successfully. But we have begun getting reports that even temephos and synthetic pyrethroids have stopped receiving the desired results against mosquitoes.

A pesticide is said to be successful when it kills over 90 per cent of the targeted insect or pest population. Over 3,500 species of mosquitoes, which play host to a number of disease-causing vectors such as zika, yellow fever, west Nile virus, etc. are said to be the deadliest animal family in the world. They kill 700 million people annually world over.
In Delhi itself, at least 10 people died of dengue last year and 9,271 people were affected.

The numbers of malaria and chikungunya cases recorded in 2017 stood at 1,142 and 940. In 2016, at least 21 dengue deaths were reported from various city hospitals. And this year, an early onset of the deadly trio dengue, malaria and chikungunya is expected with summer-like weather conditions already.

High temperature and presence of clear water in desert coolers, flower pots, coconut shells, etc, act as excellent breeding sites for the menacing insects.

We have asked municipalities to even use the fourth generation of pesticides pirimiphos-methyl and diflubenzuron in a mix with the previous generation pesticides to delay mosquitoes developing tolerance towards this in the future, the scientist explained. He said, over the years, the pesticides must be rotated in use so that their effectiveness on hardy mosquitoes does not go down.

Dr Himmat Singh, senior scientist at the National Institute of Malaria Research (NIMR), Dwarka, said, The benefit with these two latest pesticides is that they are only hormone-inhibitors, not poisons, and specific to mosquitoes. So they wouldnt have any effect on other insects, birds, mammals, fishes, etc. They are categorised as non-hazardous by WHO. However, their cost has been prohibitive so far, he said.

Delhi municipalities have begun their use after a meeting of scientists and bureaucrats of NVBDCP, NIMR, ministry of health and family welfare and the Central Insecticide Board (CIB) authorised their application in January, sources said.

Dr NR Das, head of the department of Public Health in east MCD said, We have already procured diflubenzuron on NVBDCP directions and been using it for one month satisfactorily. However, we will be able to ascertain its degree of effectiveness only after two to three months.

For at least a decade, India has been the world’s largest producer of DDT, and the largest user, spraying more DDT than the rest of the world together. China and North Korea were the only two other nations making DDT at the end of the 20th century, but both cut off production. Counter to popular conceptions, India has struggled to control malaria, often being the only nation in the world to account increases in the disease from year to year, since 2001. Malaria increased despite increasing DDT application.

To fight malaria effectively DDT spraying should be limited to Indoor Residual Spraying (IRS), which leaves a fine coat of DDT on the walls of sleeping rooms, where malaria-carrying mosquitoes bite humans, then pause on the walls to squeeze water out of the blood they’ve fed on, to reduce weight to fly. Broadscale spraying of DDT only speeds development of resistance in all mosquito species, and many other pests.

India is catching up with the rest of the world on DDT.
