Arthur Ashton’s Serendipitous Invention of Optical Tweezers

(p. B11) Arthur Ashkin, a physicist who was awarded a 2018 Nobel Prize for figuring out how to harness the power of light to trap microscopic objects for closer study, calling his invention optical tweezers, died on Sept. 21 [2020] at his home in Rumson, N.J.

. . .

Dr. Ashkin’s discovery was serendipitous.

In 1966, he was head of the laser research department at Bell Labs, the storied New Jersey laboratory founded by the Bell Telephone Company in 1925, when he went to a scientific conference in Phoenix. There, in a lecture, he heard two researchers discuss something odd that they had found while studying lasers, which had been invented six years earlier: They had noticed that dust particles within the laser beams careened back and forth. They theorized that light pressure might be the cause.

Dr. Ashkin did some calculations and concluded that this was not the cause — it was most likely thermal radiation. But his work reignited a childhood interest in the subject of light pressure.

Light pushes against everything, including people, because it comprises tiny particles called photons. Most of the time the pressure is utterly insignificant; people, for one, feel nothing. But Dr. Ashkin thought that if objects were small enough, a laser might be used to push them around.

. . .

Then, in 1986, he and several colleagues, notably Steven Chu, achieved the first practical application of optical tweezers when they sent a laser through a lens to manipulate microscopic objects. Their results were published in another paper in Physical Review Letters. Dr. Chu began using the tweezers to cool and trap atoms, a breakthrough for which he was awarded a one-third share of the Nobel Prize in Physics in 1997.

Dr. Ashkin, it was clear, was irked that the Nobel committee had not recognized his foundational work in awarding the prize. But he had already begun to use the tweezers for a different purpose: trapping live organisms and biological material.

Other scientists thought this application would not work, as he explained in an interview with the Nobel Institute after he was awarded the prize in 2018.

“They used light to heal wounds, and it was considered to be deadly,” he said. “When I described catching living things with light, people said, ‘Don’t exaggerate, Ashkin.’”

. . .

Dr. Ashkin was awarded one-half the 2018 physics prize, . . . . In so doing he became, at 96, the oldest recipient of a Nobel Prize at the time.

. . .

Dr. Ashkin’s retirement from Bell Labs did not stop him from continuing his research. When he received word of his Nobel Prize, he was working on a project in his basement to improve solar energy collection. Asked if he was going to celebrate, he said: “I am writing a paper right now. I am not about celebrating old stuff.”

Founder Re-Acquires StubHub

In my book Openness to Creative Destruction: Sustaining Innovative Dynamism, I praise project entrepreneurs for having as their main goal, not wealth or fame, but making a ding in the universe (to use Steve Jobs’s phrase). I also suggest that they are more likely to succeed, in part because they are more likely to stick with the venture they founded. But there may be exceptions to my narrative. Eric Baker sounds like a project entrepreneur who left his start-up because of conflicts with his co-founder, and who now is back in charge.

(p. B4) Eric Baker long envisioned bringing together the two ticketing companies he started.

This week eBay Inc. agreed to sell its StubHub unit, a business Mr. Baker launched nearly two decades ago, to Geneva-based Viagogo Entertainment Inc., the ticketing firm with a large European presence he has been running since 2006.

The $4.05 billion all-cash deal would create a global ticketing juggernaut in the booming business of live events. It would also put StubHub back in the hands of the person who early on saw the opportunity in the legitimate resale of tickets.

. . .

“You had to pay through the nose or find people on the street corner to purchase from,” says Mr. Baker. He felt there had to be a better, more efficient way to find tickets and imagined that could happen online.

He headed to Stanford Graduate School of Business that fall and, together with classmate Jeff Fluhr, started StubHub—then called Liquid Seats—in 2000.

. . .

Mr. Baker and Mr. Fluhr—who was chief executive and had majority ownership of the company—had their differences, and in 2004 Mr. Baker left at the board’s direction, said people familiar with the decision.

. . .

When eBay bought StubHub in 2007, Mr. Baker says he opposed the deal. “It’s rare you have the opportunity to have a business like that,” he says. “To me, you try to hold on to something that’s working.”

“Greatness in Science Often Comes From the Well-Prepared Mind Turning a Chance Observation Into a Major Discovery”

(p. 27) Takuo Aoyagi, a Japanese engineer whose pioneering work in the 1970s led to the modern pulse oximeter, a lifesaving device that clips on a finger and shows the level of oxygen in the blood and that has become a critical tool in the fight against the novel coronavirus, died on April 18 [2020] in Tokyo.

. . .

Mr. Aoyagi’s contribution to medical science was built on decades of innovation and invention. In an essay about Mr. Aoyagi, John W. Severinghaus, a professor emeritus of anesthesia at the University of California, San Francisco, wrote in 2007 that Mr. Aoyagi’s “dream” had been to detect oxygen saturation levels without having to draw blood.

. . .

But he soon ran into a problem. Blood does not flow smoothly like an open tap, but pulses through the body irregularly, thus preventing an accurate recording of dye levels. The problem, however, turned out to be an opportunity. By devising a mathematical formula to correct for this “pulsatile noise,” he created a device that measured oxygen levels with greater accuracy than before.

“Greatness in science, often, as here, comes from the well-prepared mind turning a chance observation into a major discovery,” Dr. Severinghaus wrote.

“Robinson Insisted That Creativity Can Be Taught”

(p. B12) Ken Robinson, a dynamic, influential proponent of stimulating the creativity of students that has too often been squelched by schools in the service of conformity, died on Aug. 21 [2020] at his home in London.

. . .

Mr. Robinson consulted with governments and schools around the world, conducted workshops and wrote books, including “Out of Our Minds: Learning to Be Creative” (2001) and “You, Your Child and School: Navigate Your Way to the Best Education” (2018), with Lou Aronica.

He preached that schools needed not only to broaden their curriculums but also to support teachers as creative professionals and to personalize learning by breaking large classrooms — artificial environments that invite boredom, he said — into small groups.

“Kids will take a chance,” he said in the TED Talk. “If they don’t know, they’ll have a go. Am I right? They’re not frightened of being wrong.” But, he added, “By the time they get to be adults, most kids have lost that capacity.”

Mr. Robinson insisted that creativity can be taught — not through direct instruction, but by giving students opportunities, inspiration, encouragement and mentoring.

The educator Salman Khan said that his popular online website Khan Academy draws on Mr. Robinson’s teachings in part by personalizing curriculums to meet individual students’ needs.

“He opened our eyes to an educational system that isn’t fair to a lot of kids and holds back their potential,” Mr. Khan said in a phone interview. “He helped a lot of educators, including myself, say, ‘Hey, look, this is a time to change.’ ”

Oligopolists Compete Intensely

(p. B3) The race is on between the world’s largest videogame console makers, this time during a period of heightened demand for at-home entertainment through the coronavirus pandemic.

Sony Corp. SNE 1.45% on Wednesday said two versions of the PlayStation 5 would go on sale in November, one for roughly $400 and another for $500. Both consoles will be sold in a small number of countries including the U.S. and Japan starting Nov. 12 and the rest of the world a week later.

Last week, Microsoft Corp. said it would release two new consoles as well, the Xbox Series X for $499 and the Series S for $299, on Nov. 10.

“The F.D.A. and the Drug Houses Were in Bed Together”

(p. A22) Dr. John S. Najarian, a groundbreaking transplant surgeon who made headlines for taking on difficult cases, and who weathered a different type of headline when he was accused, and then exonerated, of improprieties related to a drug he had developed, died on Aug. 31 in Stillwater, Minn., east of Minneapolis.

. . .

In November 1982, Dr. Najarian performed what may have been his highest-profile surgery. The patient was Jamie Fiske, who became the youngest successful liver transplant recipient when Dr. Najarian performed the operation a few weeks before her first birthday. Her parents had made a widely publicized appeal for a donor.

“They were told that she wouldn’t survive that kind of an operation,” Dr. Najarian said in an oral history recorded in 2011 for the University of Minnesota’s Academic Health Center. “I’m not the kind of guy that takes that lightly. So I told them, ‘If a liver becomes available, we’ll transplant it, and it will work’ — a pretty brash statement, but it did.”

Dr. Najarian’s success with transplants was aided by a drug he developed in 1970, a type of antilymphocyte globulin known as Minnesota ALG, which addressed the biggest problem with early transplants: the rejection of the new organ. He said the drug, which he began using around 1970, gave the Minnesota transplant teams notably better results than other surgical centers were getting with a product offered by a pharmaceutical company.

“Everybody thought we were lying,” Dr. Najarian said, “because we could take patients and we could transplant them, and 65 to 70 percent of them did extremely well, whereas they were lucky to have 50 percent with the commercially available product from Upjohn.”

Other transplant centers began asking for the product, and it turned into a multimillion-dollar business for the university. But in 1992, the Food and Drug Administration, which had approved ALG as an investigational drug but not for interstate sale, stopped the program, and the federal authorities began an investigation. The university turned on Dr. Najarian, pressuring him to resign, and in 1995 he was charged with violating drug safety laws and other crimes.

Dr. Najarian maintained that the case was an attempt by the pharmaceutical industry and its friends in the F.D.A. to squash a successful treatment that was costing drug companies money by besting their products.

“The F.D.A. and the drug houses were in bed together,” he said bluntly in the oral history.

His trial in federal court in St. Paul, Minn., in 1996 provided vindication. Judge Richard Kyle threw out six of the charges, and a jury acquitted him of the other 15. The judge then took the extraordinary step of blasting the F.D.A. and the prosecutors.

“I have some questions as to why we were here at all,” Judge Kyle said.

The F.D.A., he added, “was certainly aware of what was going on, and yet they came in here as a witness to testify that somehow they were hoodwinked by this defendant and his colleagues and other people at the university.”

“We had a program here in Minnesota,” the judge added, “which, for all its problems and shortcomings, was a good program, literally saved thousands of lives.”

Science Is a Process, Not a Fixed Body of Truths

(p. 14) Both writers exemplify the humanity of science: Seager and Johnson laugh, grieve, hope, fail, try, fail and try again. “We started from almost nothing,” Johnson writes about Mars, though she could be talking about pretty much every human endeavor. “We’ve gone careening down blind alleys and taken countless wrong turns, yet somehow, miraculously, the passion, ingenuity and persistence we have brought to the enterprise have moved us toward a truer understanding of another world.”

Why keep searching for life elsewhere when we sometimes seem to have a hard time appreciating it in our own backyard? What does it say about us?

“It says we’re curious,” Seager writes. “It says we’re hopeful. It says we’re capable of wonder and wonderful things.”

Amazon’s Culture “Asks a Lot of Questions”

(p. B2) John Mackey helped popularize organic food when he co-founded Whole Foods Market four decades ago. Over the past several months, his chain of more than 500 stores has scrambled to adapt to another major shift in how Americans buy groceries.

. . .

The pandemic has accelerated an online-grocery movement that Whole Foods was already seeking to capitalize on as part of Amazon.com Inc. Mr. Mackey sold Whole Foods to the online-retail juggernaut for $13.4 billion in 2017, one of the decisions he recounts in his new book out this month, “Conscious Leadership: Elevating Humanity Through Business.”

. . .

WSJ: What merger challenges have you’ve learned from?

Mr. Mackey: Amazon has a culture that asks a lot of questions. We took a little longer to get used to that, but that’s no big deal. That’s how you learn things. They’re trying to understand our business. They want to know everything. And I think that’s healthy.

WSJ: What’s the biggest leadership lesson you’ve adopted from Jeff Bezos?

Mr. Mackey: Amazon wants you to write up a document explaining your ideas, defending them, and then you can have discussions. That’s a practice Whole Foods has adopted. Amazon’s also very data-driven. As opposed to acting from the gut, Amazon says, “Show us the data.” That’s been a good discipline for us. We do it ourselves, even when we’re not talking to Amazon.

Apple Is First U.S. Firm to Reach Two Trillion in Market Value

(p. B1) Apple Inc. on Wednesday [Aug. 19, 2020] became the first U.S. public company to eclipse $2 trillion in market value, a dizzying achievement that highlights the iPhone maker’s commanding role in the world economy.

Shares of Apple rose as much as 1.4% to $468.65, eclipsing the $467.77 mark needed to reach the milestone. They ended the day up 0.1% at $462.83, putting the company’s market value just below $2 trillion.

Manship’s Heroic Prometheus Sculpture Celebrates “the Promise of the Future”

I wanted to use a photo of Manship’s Prometheus sculpture on the cover of my book Openness to Creative Destruction: Sustaining Innovative Dynamism. My editor vetoed my choice on the grounds that Prometheus was a male and the cover design needed to be gender-neutral.

(p. C14) Think a minute, then name an outdoor sculpture in Manhattan. Chances are, you chose the gilded image of Prometheus at the heart of Rockefeller Center, . . .

. . .

In conceiving his urban commercial complex, John D. Rockefeller Jr. wanted to celebrate civilization, human achievement and the promise of the future.

. . .

It’s a very serious, and very handsome, Prometheus that Manship fashioned. He chose to depict the moment after the titan has stolen the fire and is descending to Earth, signified in the sculpture by the summit behind him, and by the sea as portrayed by the pool beneath him. Prometheus, eyes wide open, looks down toward his destination. His youthful, strong-featured face betrays not worry exactly, but acknowledgment that he will face consequences from an angry Zeus, who did not want mankind to rival the gods in any way. But Prometheus is determined to give humanity the flame in his right hand, held above his head, almost triumphantly. With his outstretched left arm, he balances himself—and Manship balances his heroic sculpture.

. . .

Manship also added an element to the whole: He suggested the quote from Aeschylus that is carved in bold capital letters on the wall behind his work, strengthening its seamless link to its setting: “Prometheus, teacher in every art, brought the fire that hath proved to mortals a means to mighty ends.”

Manship thus delivered a powerful piece of statement art.

. . .

. . . —Prometheus stands out. He is a marvel within a larger urban marvel.

Open Offices Reduce Productivity and Spread Diseases

(p. B4) When historians of the early 21st century look back on the pre-Covid era, one of the absurdities they might highlight is the vogue for gigantic, open-plan offices. The apotheosis of this trend of breaking down barriers between co-workers must surely be Facebook Inc.’s 433,555-square-foot Frank Gehry-designed open-plan office at its headquarters in Menlo Park, Calif. Opened in 2015, it’s now a ghost town, a monument to offices vacated by the pandemic.

Cramming cavernous spaces with as many desks as they could hold might have increased serendipitous interactions, but it almost certainly reduced productivity and helped spread communicable diseases, including coronavirus.

. . .

Cue the “dynamic workplace,” a pivot away from the open plan, built on the idea that with fewer employees coming to work on any given day, offices can offer them more flexibility of layout and management.

While open offices and dynamic workplaces share similar components—privacy booths and huddle rooms to escape the hubbub, cafe-like networking spaces, etc.—they’re philosophically distinct. One is intended to be a place where people come (at least) five days a week, and get most of their work done on site. The other is planned for people rotating in and out of the office, on flexible schedules they have more control over than ever.

. . .

Research on hot-desking in office spaces, for example—where employees give up a dedicated space in favor of first-come-first-serve seating—finds that it decreases socialization and trust. This happens because employees figure they might never again see the person they sit next to on a given day, says Dr. Sander. In other studies, employees complain they can’t find their colleagues, that it’s a hassle to find a new spot to work every day, and that such arrangements ignore humans’ innate territoriality and desire to make a space their own.
