Still more incredible is the fact that one person almost single-handedly created the first maps of two-thirds of the planet yet is unknown to the average citizen of Earth (while Amerigo Vespucci, whose cartographic credentials are suspect, has two continents named for him). The unsung mapmaker Marie Tharp, who earned a master’s degree in geology from the University of Michigan, worked briefly for an oil company, and then in 1948 became a drafter for a new oceanographic project led by Maurice Ewing at Columbia University. For years, Ewing’s all-male team of graduate students collected sonar soundings of the ocean floor while Tharp laboriously transformed the linear strings of depth readings into three-dimensional topography.
I will be doing a Conversations with Tyler with him, no associated public event. Here is his MIT bio:
Ed Boyden is Y. Eva Tan Professor in Neurotechnology at MIT, associate professor of Biological Engineering and Brain and Cognitive Sciences at MIT’s Media Lab and McGovern Institute for Brain Research, and was recently selected to be an Investigator of the Howard Hughes Medical Institute (2018). He leads the Synthetic Neurobiology Group, which develops tools for analyzing and repairing complex biological systems such as the brain, and applies them systematically to reveal ground truth principles of biological function as well as to repair these systems. These technologies include expansion microscopy, which enables complex biological systems to be imaged with nanoscale precision; optogenetic tools, which enable the activation and silencing of neural activity with light; robotic methods for directed evolution that are yielding new synthetic biology reagents for dynamic imaging of physiological signals; novel methods of noninvasive focal brain stimulation; and new methods of nanofabrication using shrinking of patterned materials to create nanostructures with ordinary lab equipment. He co-directs the MIT Center for Neurobiological Engineering, which aims to develop new tools to accelerate neuroscience progress.
Here are other Ed Boyden links. So what should I ask him?
This was a really good one, here is the text and audio. The opening:
TYLER COWEN: I’m here today with the great Larissa MacFarquhar. She is a staff writer for the New Yorker, considered by many to write the very best and most interesting profiles of anyone in the business. She has a very well-known book called Strangers Drowning. The subtitle is Impossible Idealism, Drastic Choices, and the Urge to Help. It’s about extreme altruists. And she’s now working on a book on people’s decisions whether or not to leave their hometown.
Here is one excerpt proper:
COWEN: If you’re an extreme altruist, are you too subject to manipulation by others? If you care so much about so many other people, and those people actually can be harmed pretty easily at low cost, does this mean that you, the extreme altruist, you just go through life being manipulated?
MACFARQUHAR It’s funny you say that because one thing that I have noticed about the extreme altruist . . . You know what? I don’t want to call them extreme altruists. I think they’re people with a very strong sense of duty.
The people I met were very, very different from each other, but one thing they had in common is they really, really barely cared about what other people thought. They had to feel that way because almost everyone they met thought they were at best weirdos, and at worst dangerous megalomaniacs. So they were unconventional in their degree of duty but also in many other ways.
COWEN: They didn’t care at all what people thought about anything they did like how they dressed or . . . ?
MACFARQUHAR: Things like that. I don’t mean they didn’t care about anything about what people thought because obviously —
COWEN: In this context they didn’t care.
MACFARQUHAR: Obviously they cared about making other people’s lives better. But yes, in terms of opinions of themselves, they were much less sensitive to that than most of us.
COWEN: Your view on how much you should be lied to if you have dementia — is that the same as what you would propose for a sibling or a child, someone you loved and knew?
MACFARQUHAR: With dementia?
COWEN: Right. Would you be consistent and apply the same standard to them that you would want for yourself?
MACFARQUHAR: Ohhh, I don’t know.
COWEN: I would say don’t lie to me, but, in fact, for others, I would be more willing to lie to them than I would wish to be lied to myself.
Try this part too:
COWEN: If during a profile, when you describe people’s looks, are you worried that you are reinforcing stereotypes?
MACFARQUHAR: No. But I have —
COWEN: But isn’t there a thing, looksism?
MACFARQUHAR: Well, of course.
COWEN: There’s sexism, there’s racism, and looksism — people who look a certain way, you should make certain inferences. Is there any way we can describe people’s looks that doesn’t run that danger?
MACFARQUHAR: Probably not. But I’ll say two things about this.
First is, I think there is far too much emphasis on describing people’s looks. Because the thing about humans is that their faces are unique, so you can describe somebody, but you’re never going to be able to call up an exact picture in a reader’s mind about what the person looks like. So what you’re doing is not really describing what they look like — what you’re doing is evoking something which, I guess, the malign form of that is looksism.
But I’ve started avoiding describing what people look like, not because it results in looksism — though I’m sure that’s true — but because, unconsciously or not, it puts the reader in a position of being outside the person, looking at them.
And also, from me:
COWEN: Could the same person be both, say, a Rwandan killer in the 1990s and an extreme altruist? Or is that a contradiction?
The dotted line at the top is the Jones-implied ratio of productivity of <= 40 year olds to >= 50 year-olds, as drawn from Figure 1 in this source.
For the construction of this data source I am indebted to PseudoMontaigne. Does it not imply that NIH funding is vastly over-allocated according to the criterion of seniority? Or might this be the rise of the lab system, where the older people are the PIs, and they in turn dole this money out to younger researchers? More middlemen, so to speak. Opinions?
The organisers of a major Indian science conference distanced themselves Sunday from speakers who used the prestigious event to dismiss Einstein’s discoveries and claim ancient Hindus invented stem cell research.
The Indian Scientific Congress Association expressed “serious concern” as the unorthodox remarks aired by prominent academics at its annual conference attracted condemnation and ridicule.
The distinguished gathering of Indian researchers and scientists hosts Nobel laureates, but in recent years has seen Hindu mythology and faith-based theories edging onto the agenda.
At this year’s congress, the head of a southern Indian university cited an ancient Hindu text as proof that stem cell research was discovered on the subcontinent thousands of years ago.
“We had 100 Kauravas from one mother because of stem cell and test tube technology,” said G. Nageshwar Rao, Vice Chancellor at Andhra University, referring to a story from the Hindu epic Mahabharata.
Rao, who was addressing school children and scientists at the event, also said a demon king from another centuries-old Hindu epic had two dozen aircraft and a network of landing strips in modern-day Sri Lanka.
“Hindu Lord Vishnu used guided missiles known as ‘Vishnu Chakra’ and chased moving targets,” added the professor of inorganic chemistry.
Event organisers tried to hose down the remarks, saying it was “unfortunate” the prestigious event had been derailed by controversy.
Here is the full account, via Anecdotal. My point here is not to make fun of India, which I am a big admirer of. Rather, successful science requires many, many cultural dimensions, not just a few, and those dimensions must be applied consistently. India has an active and mostly successful space program, is a world leader in cheap and effective heart surgery, and in general the country is teeming with innovation, including in the culinary realm I might add.
So many of you take the cultural prerequisites of science for granted, and yes Max Weber still is underrated.
Using the economic theory of contests, Gross and Bergstrom modeled a controversial alternative: awarding grants instead by partial lottery. Under a partial lottery system, funds are awarded by random draw among a pool of high-ranking grants — the top 40 percent, for example. Since applicants would be aiming to clear a lower bar for a smaller prize — a shot at the lottery instead of a guaranteed payout for winning proposals — the contest theory model predicts that applicants would spend less time trying to perfect their applications, Bergstrom said.
The vast majority of life on Earth depends, either directly or indirectly, on photosynthesis for its energy. And photosynthesis depends on an enzyme called RuBisCO, which uses carbon dioxide from the atmosphere to build sugars. So, by extension, RuBisCO may be the most important catalyst on the planet.
Unfortunately, RuBisCO is, well, terrible at its job. It might not be obvious based on the plant growth around us, but the enzyme is not especially efficient at catalyzing the carbon dioxide reaction. And, worse still, it often uses oxygen instead. This produces a useless byproduct that, if allowed to build up, will eventually shut down photosynthesis entirely. It’s estimated that crops such as wheat and rice lose anywhere from 20 to 50 percent of their growth potential due to this byproduct.
While plants have evolved ways of dealing with this byproduct, they’re not especially efficient. So a group of researchers at the University of Illinois, Urbana decided to step in and engineer a better way. The result? In field tests, the engineered plants grew up to 40 percent more mass than ones that relied on the normal pathways.
That’s John Timmer at Ars Technica summarizing a paper by South et al. in Science. The experiment was done in tobacco plants but the same pathways are used in the C3 group of plants including rice, wheat, barley, soybean, cotton and sugar beets so the applications are large.
He [Cowen] said that he agreed with the idea that influence of economics comes from a relatively small number of institutions, and he thinks the number is shrinking. “What used to be something like a ‘top six’ has over time become the ‘top two,’ namely Harvard and MIT.”
Cowen said that he doesn’t “find that entirely ideal, by any means.” But he also said that those departments deserve praise for their work. “Harvard and MIT are in fact remarkably good at finding, evaluating and attracting top talent. It is stunning how good they are at this, and we should not begrudge them that,” he said. (Cowen is an example, having earned his Ph.D. at Harvard. His undergraduate alma mater is George Mason, where he teaches.)
The centralization of top departments, he said, worries him less than do “pressures for conformity.”
Cowen added that he is sympathetic to Vigdor’s criticism, but that the centralization may be “an opportunity” for departments outside the elites to shine. “The centralized centers of influence are going to miss important ideas in their early stages,” Cowen said. “Both public choice and experimental economics came out of non-top schools,” including to some extent George Mason, he said. “So did blogging. If something is unfair, well, in part that is your big chance.”
That is from Scott Jaschik at Inside HigherEd, mostly about Jacob Vigdor and his critique of the economics profession.
Here are a few:
Contrary to the beliefs of roughly 33% of Americans, Kansas is not the flattest state. In fact, it’s the 9th flattest state, and it’s one of only two Great Plains states to make the top ten (the other is North Dakota). The flattest state is actually Florida, the second flattest state is Illinois, and the least flattest is West Virginia. (Disruptive Geo)
…The average high school GPA of a representative sample of 700 millionaires in the United States is 2.9. (Eric Barker, Barking Up the Wrong Tree: The Surprising Science Behind Why Everything You Know About Success Is (Mostly) Wrong)
…Dinosaurs roamed the earth for a long time. Tyrannosaurus Rex is closer in time to humans than to Stegosaurus. (Peter Brannen, The Ends of the World: Volcanic Apocalypses, Lethal Oceans, and Our Quest to Understand Earth’s Past Mass Extinctions)
…Pepperoni pizza is subject to more government regulation than plain cheese pizza. That’s because cheese pizzas are regulated by the Food and Drug Administration, while pepperoni pizzas—which have meat—are regulated by the Department of Agriculture. (Baruch Fischhoff and John Kadvany, Risk: A Very Short Introduction)
Here is the full list, interesting throughout.
Here is the transcript and audio, a rollicking time was had by all. We covered what you would expect us to have covered. Here is one bit:
COWEN: And that people want to maximize their overall sense of how their life has gone — do you think that is ultimately Darwinian roots? Why is that the equilibrium? Happiness feels good, right?
KAHNEMAN: Yeah, happiness feels good in the moment. But it’s in the moment. What you’re left with are your memories. And that’s a very striking thing — that memories stay with you, and the reality of life is gone in an instant. So memory has a disproportionate weight because it’s with us. It stays with us. It’s the only thing we get to keep.
COWEN: If you think of your own life, have you maximized happiness or the overall sense of how your life has gone?
COWEN: Neither. Citations?
And on his new project:
KAHNEMAN: I’ll tell you where the experiment from which my current fascination with noise arose. I was working with an insurance company, and we did a very standard experiment. They constructed cases, very routine, standard cases. Expensive cases — we’re not talking of insuring cars. We’re talking of insuring financial firms for risk of fraud.
So you have people who are specialists in this. This is what they do. Cases were constructed completely realistically, the kind of thing that people encounter every day. You have 50 people reading a case and putting a dollar value on it.
I could ask you, and I asked the executives in the firm, and it’s a number that just about everybody agrees. Suppose you take two people at random, two underwriters at random. You average the premium they set, you take the difference between them, and you divide the difference by the average.
By what percentage do people differ? Well, would you expect people to differ? And there is a common answer that you find, when I just talk to people and ask them, or the executives had the same answer. It’s somewhere around 10 percent. That’s what people expect to see in a well-run firm.
Now, what we found was 50 percent, 5–0, which, by the way, means that those underwriters were absolutely wasting their time, in the sense of assessing risk. So that’s noise, and you find variability across individuals, which is not supposed to exist.
I enjoyed this particular exchange:
COWEN: Do you think of low intelligence as yet a third independent source of error? Or is that somehow subsumed in bias and noise?
KAHNEMAN: You mean plain stupidity?
COWEN: In some cases.
COWEN: A society such as Argentina that relies so heavily on psychoanalysis — as a psychologist, do you see that as bias? Is it a placebo? Is there a placebo effect in psychoanalysis?
KAHNEMAN: You seem to attribute . . . You seem to think that I think of bias all the time.
COWEN: I can’t imagine why. That’s my bias.
KAHNEMAN: It’s like thinking of sex all the time. I really don’t think of bias that much.
COWEN: Some questions about psychologists outside of what you’ve worked on, but maybe related — Freud. What do you think of Freud’s body of work? And has it influenced you at all?
Definitely recommended, and you will find cameo appearances by Michael Nielsen and Daniel Gross.
Ms Dell and her Harvard colleagues Isaiah Andrews, Nathaniel Hendren and Stefanie Stantcheva; Parag Pathak and Heidi Williams of the Massachusetts Institute of Technology…Emi Nakamura of the University of California, Berkeley and Amir Sufi of the University of Chicago Booth School of Business…
Mr Pathak and his co-authors have compared pupils who only just made it into elite public schools with others who only just missed out, rather as Ms Dell compared villages on either side of the Pentagon’s bombing thresholds. The study showed that the top schools achieve top-tier results by the simple contrivance of admitting the best students, not necessarily by providing the best education. Ms Dell and her co-author showed that bombing stiffened villages’ resistance rather than breaking their resolve.
Ms Williams has exploited a number of institutional kinks in the American patent system to study medical innovation. Some patent examiners, for example, are known to be harder to impress than others. That allowed her to compare genes that were patented by lenient examiners with largely similar genes denied patents by their stricter colleagues. She and her co-author found that patents did not, as some claimed, inhibit follow-on research by other firms. This suggested that patent-holders were happy to let others use their intellectual property (for a fee).
Here is the article, it is an interesting piece.
Over the past 60 years, the energy efficiency of ever-less expensive logic engines has improved by over one billion fold. No other machine of any kind has come remotely close to matching that throughout history.
Consider the implications even from 1980, the Apple II era. A single iPhone at 1980 energy-efficiency would require as much power as a Manhattan office building. Similarly, a single data center at circa 1980 efficiency would require as much power as the entire U.S. grid. But because of efficiency gains, the world today has billions of smartphones and thousands of datacenters.

A specter is haunting the modern world, the specter of crypto anarchy.
Computer technology is on the verge of providing the ability for individuals and groups to communicate and interact with each other in a totally anonymous manner. Two persons may exchange messages, conduct business, and negotiate electronic contracts without ever knowing the True Name, or legal identity, of the other. Interactions over networks will be untraceable, via extensive re- routing of encrypted packets and tamper-proof boxes which implement cryptographic protocols with nearly perfect assurance against any tampering. Reputations will be of central importance, far more important in dealings than even the credit ratings of today. These developments will alter completely the nature of government regulation, the ability to tax and control economic interactions, the ability to keep information secret, and will even alter the nature of trust and reputation.
The technology for this revolution–and it surely will be both a social and economic revolution–has existed in theory for the past decade. The methods are based upon public-key encryption, zero-knowledge interactive proof systems, and various software protocols for interaction, authentication, and verification. The focus has until now been on academic conferences in Europe and the U.S., conferences monitored closely by the National Security Agency. But only recently have computer networks and personal computers attained sufficient speed to make the ideas practically realizable. And the next ten years will bring enough additional speed to make the ideas economically feasible and essentially unstoppable. High-speed networks, ISDN, tamper-proof boxes, smart cards, satellites, Ku-band transmitters, multi-MIPS personal computers, and encryption chips now under development will be some of the enabling technologies.
The State will of course try to slow or halt the spread of this technology, citing national security concerns, use of the technology by drug dealers and tax evaders, and fears of societal disintegration. Many of these concerns will be valid; crypto anarchy will allow national secrets to be trade freely and will allow illicit and stolen materials to be traded. An anonymous computerized market will even make possible abhorrent markets for assassinations and extortion. Various criminal and foreign elements will be active users of CryptoNet. But this will not halt the spread of crypto anarchy.
Just as the technology of printing altered and reduced the power of medieval guilds and the social power structure, so too will cryptologic methods fundamentally alter the nature of corporations and of government interference in economic transactions. Combined with emerging information markets, crypto anarchy will create a liquid market for any and all material which can be put into words and pictures. And just as a seemingly minor invention like barbed wire made possible the fencing-off of vast ranches and farms, thus altering forever the concepts of land and property rights in the frontier West, so too will the seemingly minor discovery out of an arcane branch of mathematics come to be the wire clippers which dismantle the barbed wire around intellectual property.
Arise, you have nothing to lose but your barbed wire fences!
Addendum: Inspiring! But see my post The Demise of Crypto Anarchy from 15 years ago.
Researchers in China who commit scientific misconduct could soon be prevented from getting a bank loan, running a company or applying for a public-service job. The government has announced an extensive punishment system that could have significant consequences for offenders — far beyond their academic careers.
Under the new policy, dozens of government agencies will have the power to hand out penalties to those caught committing major scientific misconduct, a role previously performed by the science ministry or universities. Errant researchers could also face punishments that have nothing to do with research, such as restrictions on jobs outside academia, as well as existing misconduct penalties, such as losing grants and awards.
“Almost all aspects of daily life for the guilty scientists could be affected,” says Chen Bikun, who studies scientific evaluation systems at Nanjing University of Science and Technology.
The policy, announced last month, is an extension of the country’s controversial ‘social credit system’, where failure to comply with the rules of one government agency can mean facing restrictions or penalties from other agencies.
The punishment overhaul is the government’s latest measure to crack down on misconduct. But the nature and extent of the policy has surprised many researchers. “I have never seen such a comprehensive list of penalties for research misconduct elsewhere in the world,” says Chien Chou, a scientific integrity education researcher at Chiao Tung University in Taiwan.
Here is the list of the second set of winners, in the order the grants were made, noting that the descriptions are mine not theirs:
Kelly Smith has a for-profit project to further extend a parent-run charter school system in Arizona, using Uber-like coordinating apps and “minimalist” OER methods.
Andrew L. Roberts, Northwestern University, a small grant to further his work on how sports relates to politics.
Stefan de Villiers, high school student, to create podcasts on the decisions of other high school students and how/why they become successful.
Brian Burns is working (with Samo Burja) on the history of mathematics and career networks, with special attention to the blossoming of innovation in 18th century Göttingen: “The secret to producing flourishing mathematical and scientific traditions may lie in a careful study of institutions. I will undertake this investigation and in the process uncover lost mathematical knowledge.” Gauss, Riemann, and Hilbert!
Can Olcer is one of the two entrepreneurs behind Kosmos School, a K-12 school that exists only in virtual reality, a for-profit enterprise with an emphasis on science education.
Anonymous, working on a board game for ten years, aimed at teaching basic economics, including supply and demand and the core ideas of Ronald Coase. The grant is for marketing the game.
Sophie Sandor is a 23-year-old Scottish film-maker making films with “noticeable themes [of] rational optimism, ambition and a rejection of the victimhood notion that millennials are prone to.” She is also interested in making documentaries in the education space.
Nicholas Dunk has a for-profit to bring voice recognition/machine transcription to the daily tasks of doctors. The goal is to solve paperwork problems, free up doctor time, encourage better record-keeping, and improve accuracy, all toward the end of higher quality and less expensive health care.
