Techno Supreme aka The Man Behind the Curtain Is Not a Computer


Big Fossil doesn't want it to be true:
Research shows that auto plants grew their workforces after transitioning to electric vehicle production
Sep 2024, phys.org

Researchers at the University of Michigan have shown that plants in the ramp-up stages of transitioning to full-scale EV production saw assembly jobs increase as much as 10 times. At one plant studied, now with over a decade of EV production, the number of workers needed to make each vehicle has remained three times higher.

"There is a shortage of information out there about how the transition is shaping up. What we're seeing, with the data that's available, is that the loss of employment predicted for EVs is not happening."

McDonald’s touchscreen kiosks were feared as job killers
Sep 2024, CNN Business

“In theory, kiosks should help save on labor, but in reality, restaurants have added complexity due to mobile ordering and delivery, and the labor saved from kiosks is often reallocated for these efforts. Kiosks “have created a restaurant within a restaurant.”

And in some cases, kiosks have even been a flop. Bowling ally chain Bowlero added kiosks in lanes for customers to order food and drinks, but they went unused because staff and customers weren’t fully trained on using them.

A recent study from Temple University researchers found that, when a line forms behind customers using kiosks, they experience more stress when placing their orders and purchase less food. And some customers take longer to order tapping around on kiosks and paying than they do telling a cashier they’d like to order a burger and fries.

Mindless Autonomy


Everybody loves slime molds, nature's gift to urban planning, so let's start there.

Evidently efficient - Self-organization of informal bus lines in the Global South
July 2024, phys.org

The Global North usually have centrally planned public transport systems, and the Global South has it provided by informal services and ad hoc routes. They studied 7,000 formal and informal bus lines across 36 cities and 22 countries using open GPS data.

The routes of informal transport self-organize in a way that reaches or even exceeds the efficiency level of centralized services. The findings call into question the general perception of informal transport as an "inferior alternative" to centrally organized services.

"Informal transport, however, has fewer detours and more uniform routes than centrally planned services, so the routes are efficient - and profitable even without the extensive subsidies that are common in the Global North" 

Ah yes, the transfer of money from public funds to private funds, where the public gets a less efficient, lower quality system, and rich people who own the private entities get a nice, consistent, government-guaranteed source of income for their (dis)service.

Study explores the link between stock market fluctuations and emergency room visits in China
Jul 2024, phys.org

Using daily emergency room visit records from the three largest hospitals in Beijing from 2009 to 2012, we find that a one percentage point decrease in daily market returns is associated with 0.185 increased cases of cardiovascular diseases and 0.020 increased cases of mental disorders on that day. Moreover, a one percentage point increase in daily market returns is associated with 0.035 increase in cases of alcohol abuse on that day. By contrast, diseases that are less related to psychological stress (infections, parasitic diseases, etc) are not significantly affected by market fluctuations.

Women's education influences fertility rates in sub-Saharan Africa, forecasting model finds
Nov 2024, phys.org

So it's not just GDP but also women's education that lowers fertility:

They developed a fertility forecasting model based on education levels of 138 demographic and health surveys conducted in 39 sub-Saharan African countries between 1986 and 2022, and found not only the education of the individual women matters, but also the average education of the environment in which the women live. Higher average educational attainment is significantly correlated with lower ideal family size and lower actual fertility for women in each separate education category. 

"Educated women are leading the shift towards smaller family sizes in high-fertility communities, even influencing the choices of women with less education around them."

Researchers propose a mathematical definition of cell death
Nov 2024, phys.org

"My long-term scientific goal is to understand the inherent difference between life and nonlife, mathematically; why the transition from nonlife to life is so difficult, while the other way around is so easy."

This led them to develop a computational method for quantifying the life-death boundary, which they call "stoichiometric rays." The method was developed by focusing on enzymatic reactions and the second law of thermodynamics, which states that systems naturally move from ordered to disordered states.

"We naively believe that death is irreversible, but it is not so trivial and does not have to be the case. I believe that should death come more under our control, human beings, our understanding of life, and society will change completely. In this sense, to understand death is crucial in terms of science and also in terms of social implications."

Survey shows shift in language around mental health over 79 years
Jun 2024, phys.org

340,000 texts taken from Google Books, and a combination of the Corpus of Historical American English, and the Corpus of Contemporary American English, and spanning 79 years from 1940–2019, using a list of generic terms for mental ill health. It's important to note that the authors here have specifically looked at numerical frequency of word usage in written culture, rather than community word preferences over time.
  • Generic terms for mental ill health appeared more than twice as often in 2019 as in 1940
  • Phrases which included "disease," and "disturbance" grew less common over time
  • Phrases that included words like "mental health," "psychiatric," and "illness" were used more commonly
  • In particular, "mental illness," after a spike in popularity between the 1940s and 1960s, reigned as the most-used term.

Study finds politicians use simpler language on hot days
Jun 2024, phys.org

They used seven million parliamentary speeches representing more than 28,000 politicians in eight different countries over several decades combined with global meteorological data.

Hot days reduce language complexity but cold days did not have the same effect.

They looked closer using a subset in Germany: The larger effect size observed in older politicians could be because older individuals are more susceptible to extreme temperatures.

How higher-order interactions can remodel the landscape of complex systems
Oct 2024, phys.org

Higher-order interactions can lead to deeper "basins of attraction," which are collections of starting points that end up at the same state as the system moves forward in time. If the system were a pendulum, the lowest point is an attractor, and every possible starting point is in the basin of attraction because they all eventually converge there. 

If the system were a brain working through a complicated math problem, then the thought processes that lead to a solution—hopefully the correct one—are in the basin of attraction. A deeper basin means that the solutions are more stable—that is, starting points get to the bottom faster or more quickly recover from small perturbations.

But even though the basins get deeper, they become narrower. What starting points do end up in the basin get there faster, but overall, fewer starting points lead to the bottom.

This one is old as hell:
Aging societies more vulnerable to collapse, suggests analysis
Dec 2023, phys.org

This new study shows that pre-modern states faced a steeply increasing risk of collapse within the first two centuries after they formed.

"This approach is commonly used to study the risk of death in aging humans, but nobody had the idea to look at societies this way." 

In humans, the risk of dying doubles approximately every six to seven years after infancy. As that exponential process compounds with great age, few people survive more than 100 years. The authors show that it works differently for states. Their risk of termination rises steeply over the first two centuries but then levels off, allowing a few to persist much longer than usual.

They found a similar pattern all over the world from European pre-modern societies to early civilizations in the Americas to Chinese dynasties. (Gulps in American)

RIKEN calling in:
Chaotic dynamics in the brain may enable probabilistic thinking
Jul 2024, phys.org    

Even when watching a blank screen with no sound, neurons in the cortex fluctuate spontaneously. Some experiments suggest that this spontaneous activity corresponds to the brain ruminating over imagined possible scenarios—perhaps based on sensory inputs the brain has been presented with in the past, and that this activity follows chaotic dynamics.

The pair fed a computational neural network, driven by chaotic dynamics, with sensory inputs about an object's location.

"One neuron would fire for the object being in the north, another for it being in the northeast, and so on." At any one moment, because of the chaos, the firing neuron can change irregularly. But when averaged over time, the frequency of neurons firing mapped to the correct probability for the object's location.

"In our model, the ultimate probabilistic distribution is robust and gives nearly optimal results, despite the chaos."

Exploring the evolution of social norms with a supercomputer
Aug 2024, phys.org

RIKEN meets the Max Planck Institute for Evolutionary Biology; you're in some sh** now:

Thye've created an arena of natural selection (artificial selection) for social norms, so they fight it out and see who wins. This is hard because the norms added to the model, the more complex the interactions. But that's ok, because they used RIKEN's Fugaku, one of the fastest supercomputers worldwide.

They analyzed the reputation dynamics among all 2,080 norms of a natural complexity class, the so-called "third-order norms."

The research shows that cooperative norms are difficult to sustain if the population consists of a single well-mixed community. However, if the population is subdivided into several smaller communities, cooperative norms evolve more easily.

The most successful norm in the simulations is particularly simple. It views cooperation as universally positive and defection as generally negative—except when defection is used as a means to discipline other defectors.

It suggests that the structure of a population significantly influences which social norms prevail and how durable cooperation is.

The Offloading of Executive Function as Precursor to the Singularity


When they said the phone had become your exocortex, they were not kidding - the executive function of a human is being outsourced to computers (algorithms, AI, etc.); we're seeing it happen in real time. Not sure what this means for the future of humans, and not sure what the intorduction of the alphabet did in this regard, or what Socrates would have said about all this, but here we are:

(Don't forget the incentive here - with the offloading of executive control, we also offload liability.)

Internet addiction affects behavior and development of adolescents, study finds
Jun 2024, phys.org

Meta study of small groups but fMRI: 12 articles involving 237 young people aged 10–19 with a formal diagnosis of internet addiction between 2013 and 2023.

The effects of internet addiction were seen throughout multiple neural networks in the brains of adolescents. There was a mixture of increased and decreased activity in the parts of the brain that are activated when resting (the default mode network).

Meanwhile, there was an overall decrease in the functional connectivity in the parts of the brain involved in active thinking (the executive control network).

These changes were found to lead to addictive behaviors and tendencies in adolescents, as well as behavior changes associated with intellectual ability, physical coordination, mental health and development.

And now, speaking of executive function, it appears that the executives among us (i.e., managers) are the most at-risk and yet the most unwilling to recognize that they are squarely on the chopping block in the coming revolution:

Economist says hybrid work is a 'win-win-win' for productivity, performance and retention
Jun 2024, phys.org

Sometimes the truth is easy, not often but sometimes:

In a randomly controlled experiment on more than 1,600 workers at one of the world's largest online travel agencies, Trip.com, employees who worked from home for two days a week were just as productive and as likely to be promoted as their fully office-based peers.

On a third key measure, employee turnover, the results were also encouraging. Resignations fell by 33% among workers who shifted from working full-time in the office to a hybrid schedule. Women, non-managers, and employees with long commutes were the least likely to quit their jobs when their treks to the office were cut to three days a week. Trip.com estimates that reduced attrition saved the company millions of dollars.

Also, resignations fell only among non-managers; managers were just as likely to quit whether they were hybrid or not.

And, managers predicted on average that remote working would hurt productivity, only to change their minds by the time the experiment ended.

Opponents say that employee training and mentoring, innovation, and company culture suffer when workers are not on site five days a week, but critics often confuse hybrid for fully remote.

This suggests that problems with fully remote work arise when it's not managed well.

Using AI to train AI: Model collapse could be coming for LLMs
Jul 2024, phys.org

The research shows that within a few generations, original content is replaced by unrelated nonsense, demonstrating the importance of using reliable data to train AI models. This is called model collapse. 

They found that feeding a model AI-generated data causes successive generations to degrade in their ability to learn, eventually leading to model collapse.

Nearly all of the recursively trained language models they tested tended to display repeating phrases. For example, a test was run using text about medieval architecture as the original input and by the ninth generation the output was a list of jackrabbits.

The authors propose that model collapse is an inevitable outcome of AI models that use training datasets created by previous generations.

"The problems arise when this synthetic data training is, inevitably, repeated, forming a kind of a feedback loop--what we call an autophagous or 'self-consuming' loop," said Richard Baraniuk, Rice's C. Sidney Burrus Professor of Electrical and Computer Engineering. "Our group has worked extensively on such feedback loops, and the bad news is that even after a few generations of such training, the new models can become irreparably corrupted. This has been termed 'model collapse' by some--most recently by colleagues in the field in the context of large language models (LLMs). We, however, find the term 'Model Autophagy Disorder' (MAD) more apt, by analogy to mad cow disease."

"It is clear that differences between individuals cannot be eliminated simply by means of training; in the future, user interfaces need to be streamlined for simpler use.

We cannot promote a deeper and more equal use of computers in society unless we solve this basic problem."

"However, the research findings also show that age remains the most important factor in how well an individual can use applications. Older people clearly took more time to complete their tasks, and they also felt that the assignments were more burdensome."

Peak Climate Confusion


There's a lot happening in the climate news, but Network Address is less interested in the facts, and more interested in the meta-facts, like how many superlatives an article uses, or how many new words have to be coined in order to keep track of what the heck is going on, or just cases where the weather centers monitoring disasters are themselves in the disaster zone, or maybe just outer space observatories that were never meant to be weather stations yet provide more accurate data than actual weather stations. It's all in there:

Shipping emissions regulations enacted in 2020 improved air quality but accelerated warming
Aug 2024, phys.org

Regulations put into effect in 2020 by the International Maritime Organization required a roughly 80% reduction in the sulfur content of shipping fuel used globally.

They scanned over a million satellite images and quantified the declining count of ship tracks, estimating a 25 to 50% reduction in visible tracks. Where the cloud count was down, the degree of warming was generally up.

Further work by the authors simulated the effects of the ship aerosols in three climate models and compared the cloud changes to observed cloud and temperature changes since 2020. Roughly half of the potential warming from the shipping emission changes materialized in just four years, according to the new work. In the near future, more warming is likely to follow as the climate response continues unfolding. (Although it is noted that the magnitude of warming in 2023 is too significant to be attributed to the emissions change alone, according to their findings.)

The National Climatic Data Center maintains the world's largest climate data archive and provides historical perspective to put present-day weather conditions and natural disasters into context in a warming world due to climate change.

Unfortunately, the National Climatic Data Center is based in Asheville, North Carolina. As I write this, the center's website remains offline. That's because Asheville, a city in North Carolina's Blue Ridge Mountains, is the epicenter of catastrophic flooding from Hurricane Helene that has played out over the last week. The climate data facility is inoperable because water and electricity services in the region have entirely broken down due to flooding.

Observatory finds local 1.1 ºC increase in 20 years, twice as much as predicted by climate models
Oct 2024, phys.org

Surprise - At the observatory, the weather station has sent data on temperature, relative humidity, atmospheric pressure and wind speed and direction every two seconds for the past twenty years. "The station was built with the intention to have some guidance for telescope operations, not to characterize local weather professionally, let alone the effects of climate change on the measured parameters. But the fact that they were relatively low-cost devices has been an advantage, since they had to be changed and recalibrated every two years or so, which has favored the reliability of the data and greatly limited the effects of long-term sensor drifts, which are difficult to detect."

But alas - The experimental data obtained show an increase of 1.1ºC over the past 20 years, i.e., 0.55ºC per decade. This is more than double the increase predicted by climate models for the same area, and even more than expected for the next 20 years.

One example - creating a giant submarine curtain that would at least partially prevent warm tidal currents from reaching the glacier ice.

Unexplained heat-wave 'hotspots' are popping up across the globe
Nov 2024, phys.org

Just here for the ad copy:

Distinct regions are seeing repeated heat waves that are so extreme, they fall far beyond what any model of global warming can predict or explain.

For instance, a nine-day wave that hammered the U.S. Pacific Northwest and southwestern Canada in June 2021 broke daily records in some locales by 30°C, or 54°F. This included the highest ever temperature recorded in Canada, 121.3°F, in Lytton, British Columbia. The town burned to the ground the next day ... .

You know we're having a problem making sense of what's happening with the climate when we're willing to take into consideration the quantum effects of water:

Quantum mechanism identified as a key to accelerating ocean temperatures
Nov 2024, phys.org

Professor Smith said the apparent role of non-thermal energy in accelerating ocean temperatures now needs to be factored into climate models:

"When ocean water is heated by radiation from the sun and the sky it stores energy not only as heat, but as hybrid pairs of photons coupled to oscillating water molecules.

"These pairs are a natural form of quantum information, different to the information researchers are pursuing in the development of quantum computing. This extra store of energy has always been present and aided ocean thermal stability prior to 1960.

"But now the average heat dissipated overnight from each day's heating is no longer stable as extra heat input from Earth's atmosphere raises both forms of stored energy [including the quantum energy described above]."

On the heels of recent concern over the use of the word "tipping point" as having become kind of useless, and the scientific community is asking to stop using the word because it's confusing and counterproductive:

Rapid surge in global warming mainly due to reduced planetary albedo, researchers suggest
Dec 2024, phys.org

Far worse than expected - not only is it yes to the shipping sulfur aerosols, but also the warming itself is doing this, which means we've passed the tipping point (decades early).

"The 0.2-degree-Celsius 'explanation gap' for 2023 is currently one of the most intensely discussed questions in climate research."

One trend appears to have significantly affected the reduced planetary albedo: the decline in low-altitude clouds in the northern mid-latitudes and the tropics. In this regard, the Atlantic particularly stands out, i.e., exactly the same region where the most unusual temperature records were observed in 2023. [Albedo being the reflection of sunlight back off the earth, so that it never accumulates as heat.]

"It's conspicuous that the eastern North Atlantic, which is one of the main drivers of the latest jump in global mean temperature, was characterized by a substantial decline in low-altitude clouds not just in 2023, but also—like almost all of the Atlantic—in the past 10 years." 

It appears global warming itself is reducing the number of low clouds.

"If a large part of the decline in albedo is indeed due to feedbacks between global warming and low clouds, as some climate models indicate, we should expect rather intense warming in the future. We could see global long-term climate warming exceeding 1.5 degrees Celsius sooner than expected to date."

Give Me Some Skin


Nope nope nope.

Faces made of living skin make robots smile
Jun 2024, BBC News

Tokyo University makes Face on a Chip (see the above image) - The trick the team employed was to use a special collagen gel for adhesion, which is naturally viscous so difficult to feed into the minuscule perforations. But using a common technique for plastic adhesion called plasma treatment, they managed to coax the collagen into the fine structures of the perforations while also holding the skin close to the surface in question.

Something like a face-on-a-chip could be useful in research into skin aging, cosmetics, surgical procedures, plastic surgery and more. (Follow the link and watch it move.)

Scientists create 'living bioelectronics' that can sense and heal skin
May 2024, phys.org

They made a new kind of bioelectronics that uses not just the electronics and a soft layer to make them less irritating to the body, but now a layer of living cells made of a gel from tapioca starch and gelatin, with S. epidermidis microbes tucked in. S. epidermidis microbes secrete compounds that reduce inflammation.

Rewritable, recyclable 'smart skin' monitors biological signals on demand
May 2024, phys.org

The researchers made an adhesive composite with molecules called polyimide powders that add strength and heat resistance and amine-based ethoxylated polyethylenimine - a type of polymer that can modify conductive materials - dispersed in a silicone elastomer (rubber) to monitor the pH value, glucose and lactate concentrations in sweat as well as detecting via finger prick blood draws. It can also be reprogrammed to monitor heart rate, nerve performance and sweat glucose concentrations in real time.

AI headphones let wearer listen to a single person in a crowd by looking at them just once
May 2024, phys.org

"Target Speech Hearing" - wear the headphones and look at a person speaking for three to five seconds to "enroll" them. The system then cancels all other sounds in the environment and plays just the enrolled speaker's voice in real time. The sound waves from the speaker's voice reach the microphones on both sides of the headset simultaneously, and that's how works.

Samuel Johnson, Biography




These are notes taken from  Samuel Johnson's biography, but the one by John Wain 1974, so this is not the official Boswell biography.

Image credits: Samuel Johnson by Joshua Reynolds, the first picture in 1775 and the second in 1772. The third picture had to wait until about 2010, but comfortably inhabits the internet hall of fame as a meme, seen here in the original macro image series formula, and usually placed after a screenshot of some crazy comment or question already posted online (filed as "dafuq" as in "wtf did I just read").

  • On the Episode of Dr. Swinfin and the Latin Document (AKA 1700's HIPAA) - Johnson calls on a Dr. Swinfin to help with his depression, but because of his enviable command of language, he wrote out his symptoms in Latin, to which Swinfin was so impressed, he showed all his friends. p59
  • On Living Cheaply - he only made social calls on 'clean shirt days' p80
  • On Psalmanazar the Faker - this was a friend of his, and this guy is so crazy, I need to write it out: He (Psalm.) got taken into another man's plot, to be 'converted' to Christianity by baptism, but pretending ot be Formosan it made the other guy look good as a clergyman. It worked, and the clergyman got his chaplaincy, and Psalmanazar stayed in London, as a Formosan, while he completely fabricated a book about his birthplace (published 1704). But wait - in the process he created a fake Formosan language, and made up all the letters, and was send to Oxford to teach it to young men who would go as missionaries. He would burn a candle all night in his window so people thought he was studying non-stop. p121 (no update given on what happened to those poor missionaries)
  • Samuel Johnson started his Dictionary at a time when England was not yet as powerful as an empire. They didn't have all the academies and learned men and public money and private patronage. They had an agreement between seven different booksellers and the genius of S.J. The biography's author calls this an example of the 'enlightened behavior' the free market is sometimes capable of. p130
  • The most polite letter ever - actually he was a very polite person in general, but this I'd like to copy, for the edification of any reader; this was written to a gentleman who asked how he could get a copy of the Dictionary when it came out, and despite his being a total stranger, Johnson wrote this response: Sire, If you imagine that by delaying my answer I intended to show any neglect of the notice with which you have favored me, you will neither think justly of yourself nor of me. Your civilities were offered with too much elegance not to engage attention, and I have too much pleasure in pleasing men like you, not to feel very sensibly the distinction which you have bestowed upon me. ... p200-201
  • On what I will call the Evolution of Authority; he's working with a professor at Oxford to help him write lectures, this one is about kingship, called "The King and his Coronation Oath" - In that age of prejudice and ignorance, when the civil institutions were yet few, and the securities of legal obligation very weak, both because offenses against the law were often unpunished, and because the law itself could be but little known, it was necessary to invest the king with some thing of a sacred character that might secure obedience by reverence, and more effectually preserve his person from danger and violation. For this reason it was necessary to interpose the clerical authority that the crown being imposed by a holy hand might communicate some sanctity to him that wore it. And, accordingly, the inauguration of a king is by our ancient historians termed consecration; and the writings, both fabulous and historical, of the Middle Ages connect with royalty some supernatural powers. p272
  • And then, he's writing about the American colonists (and he's kind of against them I think), but I might just call it 'Being Human' - No man has a right to any good without partaking of the evil by which that good is necessarily produced; no man has a right to security by another's danger, nor to plenty by another's labor, but as he gives something of his own which he who meets the danger, or undergoes the labour, but as he gives something of his own which he who meets the danger, or undergoes the labour considers as equivalent; no man has a right to the security of government without bearing his share of inconveniences. ... If by forsaking our native country we could carry away all its happiness and leave its evils behind, what human being would not wish for exile? p272
  • "A decent provision of the poor is a true test of a civilization." p280
  • Forsooth!
  • They used to wear an ink horn dangling from the lapel, for writing on the go. p357

Benjamin Franklin's Autobiography


Written 1706-1790; this is considered the first autobiography (a la Albrecht Dürer's self-portrait?)
  • Says the Pope, judiciously: "Men should be taught as if you taught them not. And things unknown propos'd as things forgot."
  • Ben Franklin became a vegetarian because of that guy's book Way to Health(?), until he realized that animals eat other animals - he saw a fish get cut open once, and other fish were in its stomach.
  • (Talking shit) It was a habit he had acquired. He wanted to please everybody, and having little to give, he gave expectations. 
  • "Taking a Saint Monday" is when you're hung over from Sunday night, and call out of work.
  • He mentions how when they wanted to increase circulation of paper money, rich people didn't like the idea, but they had nobody to write about it. Ben Franklin could write, and had his own press, so he wrote in favor, and it happened. Imagine a day when simply knowing how to write made you that valuable. But also imagine a time when it was so rare that even "the rich" couldn't find one. 
  • I think "shut up" originally meant shut up in the house, not to shut your mouth.
  • He seems to think that reading, in itself, makes you a better person. Granted, it was very new at the time, and so yes it may have given you a huge advantage, like having a PhD today.
  • Imagine the nerve - "In the conduct of my newspaper I carefully excluded libeling and personal abuse, which is of late years become so disgraceful to our country. Whenever I was solicited to insert anything of that kind, and the writers pleaded as they generally did, the liberty of the press, and that a newspaper was like a stagecoach in which any one who would pay had a right to a place, my answer was, that I would print the piece separately if desired, and the author might have as many copies as he pleased to distribute to himself, but that I would not take upon me to spread his detraction, and that having contracted with my subscribers to furnish them with what might be either useful or entertaining, I could not fill their papers with private altercation in which they had no concern without doing them manifest injustice. ... These things I mention as a caution to young printers, and that they may be encouraged not to pollute their presses and disgrace their profession by such infamous practices, but refuse steadily .... In the Pennsylvania Gazette for June 10, 1731, Franklin wrote of having displeased many men "for refusing absolutely to print any of their party or personal reflections". On December 24, 1782, he wrote Francis Hopkinson: "If people will print heir abuses of one another, let them do it in little pamphlets, and distribute them where they think proper.
  • He tells a story of a guy he doesn't like, but who he has no choice but to cooperate with, and who is above him in station, and who would likely be for a long time: "I did not however aim at gaining his favor by paying any servile respect to him, but after some time took this other method. Having heard that he had in his library a certain very scarce and curious book, I wrote a note to him expressing my desire of perusing that book, and requesting he would do me the favor of lending it to me for a few days. He sent it immediately; and I returned it in about a week, with another note expressing strongly my sense of the favor. When we next met in the House he spoke to me, (which he had never done before) and with great civility. And he ever afterwards manifested a readiness to serve me on all occasions, so that we became great friends and our friendship continued to his death. Tis is another instance of the truth of an old maxim I had learned, which says, He that has once done you a kindness will be more ready to do you another, than he whom you yourself have obliged. And it shows how much more profitable it is prudently to remove, than to resent, return and continue inimical proceedings. [inimical: adverse, hurtful, enemy]
  • Ben Franklin on vaccines (in the *** 1700's) - In 1736 I lost one of my sons, a fine boy of 4 years old, by the smallpox taken in the common way. I long regretted bitterly and still regret that I had no given it to him by inoculation. This I mention for the sake of parents, who omit that operation on the supposition that they should never forgive themselves if a child died under it; my example showing that the regret may be the same either way, and that therefore the safer should be chosen. 
  • Note, also from the 1700's, most of the profits of his paper came from advertisements.
