The treadmill
I've mentioned before how my difficulties with math short-circuited my goal of becoming a researcher in physics, but the truth is, there's more to the story than that.
Even after I realized that I didn't have the mathematical ability -- nor, honestly, enough interest and focus to overcome my challenges -- I still had every intention of pursuing a career in science. I spent some time in the graduate school of oceanography at the University of Washington, and from there switched to biology, but I found neither to be a good fit. It wasn't a lack of interest in the disciplines; biology, in fact, is still a deep and abiding fascination to this day, and I ultimately spent over three decades teaching the subject to high schoolers. What bothered me was the publish-or-perish atmosphere that permeated all of research science. I still recall my shock when one of our professors said, "Scientists spend 25% of their time doing the research they're interested in, and 75% of their time trying to beat everyone else in the field to grant money so they don't starve to death."
It's hard to pinpoint an exact moment that brought me to the realization that the career I'd always dreamed of wasn't for me -- but this was certainly one of the times I said, "Okay, now, just hang on a moment."
I'm not alone in having issues with this. The brilliant theoretical physicist Sabine Hossenfelder did a video on her YouTube channel called "My Dream Died, and Now I'm Here" that's a blistering indictment of the entire edifice of research science. Hossenfelder has the following to say about how science is currently done:
It was a rude awakening to realize that this institute [where she had her first job in physics research] wasn't about knowledge discovery, it was about money-making. And the more I saw of academia, the more I realized it wasn't just this particular institute and this particular professor. It was generally the case. The moment you put people into big institutions, the goal shifts from knowledge discovery to money-making. Here's how this works:The topic comes up today because of two separate studies that came out in the last two weeks that illustrate a hard truth that the scientific establishment as a whole has yet to acknowledge; there's a real human cost to putting talented, creative, bright people on the kind of treadmill Hossenfelder describes.
If a researcher gets a scholarship or research grant, the institution gets part of that money. It's called the "overhead." Technically, that's meant to pay for offices and equipment and administration. But academic institutions pay part of their staff from this overhead, so they need to keep that overhead coming. Small scholarships don't make much money, but big research grants can be tens of millions of dollars. And the overhead can be anything between fifteen and fifty percent. This is why research institutions exert loads of pressure on researchers to bring in grant money. And partly, they do this by keeping the researchers on temporary contracts so that they need grants to get paid themselves... And the overhead isn't even the real problem. The real problem is that the easiest way to grow in academia is to pay other people to produce papers on which you, as the grant holder, can put your name. That's how academia works. Grants pay students and postdocs to produce research papers for the grant holder. And those papers are what the supervisor then uses to apply for more grants. The result is a paper-production machine in which students and postdocs are burnt through to bring in money for the institution...
I began to understand what you need to do to get a grant or to get hired. You have to work on topics that are mainstream enough but not too mainstream. You want them to be a little bit edgy, but not too edgy. It needs to be something that fits into the existing machinery. And since most grants are three years, or five years at most, it also needs to be something that can be wrapped up quickly...
The more I saw of the foundations of physics, the more I became convinced that the research there wasn't based upon sound scientific principles... [Most researchers today] are only interested in writing more papers... To get grants. To get postdocs. To write more papers. To get more grants. And round and round it goes.

The science of beauty
Here's the email:
Dear Mr. Skepto,You sound pretty worried that you don't have an explanation for everything. People aren't always explainable! They do things because they do them. That's it. Some people believe weird stuff and some people like the explanations from science. Just like some people like the Beatles and some people like Beethoven. It's silly to wear yourself out trying to figure why.Do you worry about why your loved ones love you? Maybe it's some chemical thing in their brain, right? Do you tell your wife that's what love means? Maybe it's a gene or something that's why I think flowers are pretty. If so, the explanation is uglier than the flowers are. I'd rather look at the flowers.All your scientific explanations do is turn all the good things in life into a chemistry class. I think they're worth more than calling them brain chemicals. I'll take religion over science any day. At least it leaves us with our souls.Think about it.L. D.
But you probably already knew that.
There is a reason why musical tastes exist. We're nowhere near the point in brain research where we could discern the explanation; but an explanation does exist for why Shostakovich's Prelude & Fugue in E-flat Minor gives me goosebumps (especially in this recording, played by the composer himself!), while Brahms's symphonies might send someone else into raptures but do nothing for me whatsoever. Nothing just "is because it is."
And I can't fathom how knowing the explanation devalues your appreciation of the thing itself. Me, I would love to know what's happening in my brain when I hear a piece of music I enjoy. We're beginning to get some perspective on this, starting with a 2011 study that found that the neurological response to hearing a piece of music we love is similar to the brain's response to sex.
Cool, yes? I think that's awesome. How would knowing that make me appreciate music less?
Or sex either?
I find flowers even more beautiful knowing that their shapes and colors evolved to attract pollinators, and understanding a bit about the chemistry of photosynthesis.
Tell me why the stars do shineA more scientific type added a verse, to wit:
And tell me why the ivy twines
And tell me why the sky is blue,
And I will say why I love you.
Nuclear fusion is why the stars do shine.Which I think is not only hilarious, it's a good deal more realistic than attributing it all to souls and people "doing things because they do them."
Thigmotropism is why the ivy twines.
Rayleigh scattering is why the sky's so blue,
And testicular hormones are why I love you.
In short: science itself is beautiful. Understanding how the world works should do nothing but increase our sense of wonder. If scientific inquiry isn't accompanied by a sense of "Wow, this is amazing!", you're doing it wrong. I'll end with a quote from Nobel Prize winning physicist Richard Feynman, who in his 1988 book What Do You Care What Other People Think? had the following to say:
I have a friend who's an artist, and he sometimes takes a view which I don't agree with. He'll hold up a flower and say, "Look how beautiful it is," and I'll agree. But then he'll say, "I, as an artist, can see how beautiful a flower is. But you, as a scientist, take it all apart and it becomes dull." I think he's kind of nutty… There are all kinds of interesting questions that come from a knowledge of science, which only adds to the excitement and mystery and awe of a flower. It only adds. I don't understand how it subtracts.

Attitude conversion
Here's a hypothetical for you.
There's a therapeutic practice being proposed for widespread use. It has the following drawbacks:
- its use is strongly correlated with long-term PTSD, depression, and suicidal ideation.
- over half of the patients recommended for this practice are referred not by medical professionals, but by religious leaders.
- it has been denounced by every major medical organization.
- it has very close to a zero percent success rate.
It's attitudes that need to be converted, not people's sexual identity.
People are enraged about the non-issue of children being given sex-change operations on a whim -- like Donald Trump's idiotic lie, "The transgender thing is incredible. Think of it. Your kid goes to school and comes home a few days later with an operation. The school decides what’s going to happen with your child." (I worked in a school for 32 years, and trust me, school nurses are not equipped to do surgery. And nothing in a school happens apropos of a child's health without parental consent, unless it's a life-or-death emergency. Nothing.)
So if you want to be furious about something, how about choosing something real, something that actually does demonstrable and long-lasting harm?
And then take that fury and turn it into something useful -- working to ban forever a practice that does irreparable damage to the mental health of one of the most vulnerable minorities.

A battle between unknowns
"A causeway that crossed the Tollense River, constructed about five hundred years before the battle, is thought to have been the starting point of the conflict," said study co-author Thomas Terberger, of the University of Göttingen. "The causeway was probably part of an important trade route. Control of this bottleneck situation could well have been an important reason for the conflict... This new information has considerably changed the image of the Bronze Age, which was not as peaceful as believed before. The thirteenth century B.C.E. saw changes of burial rites, symbols and material culture. I consider the conflict as a sign that this major transformation process of Bronze Age society was accompanied by violent conflicts. Tollense is probably only the tip of the iceberg."

Not magic
I got in a friendly argument online a few days ago with someone who finds my reliance on the scientific method "limited." (His word.)
He accepts science, he said, but added that if that's your only way of understanding, there's stuff you'll miss. "There are features of reality that science can't, or won't, study," he said. "Science deals with what is tangible and quantifiable; there are other ways of knowing that allow you to access what is intangible and unquantifiable. Without those, you're ignoring half of the universe."
The whole thing put me in mind of biologist Stephen Jay Gould's idea of non-overlapping magisteria -- that there are different domains of inquiry, and science only addresses one of them. (Gould considered religion to be one of those other magisteria -- and that science and religion could coexist just fine unless one chose to tread on the other's toes.)
The problem with this is that science has been progressively chewing away at the other magisteria, as more and more of the universe is explained scientifically. Phenomena that were thought to be utterly mysterious are now accounted for by rational scientific models -- heredity and tectonic activity are just two of many examples. (In some realms -- such as legal documents -- we still have vestiges of this older way of thinking, in calling certain natural occurrences "acts of God.")
Even some religious people are uncomfortable with this approach. Theologian Dietrich Bonhoeffer referred to it as "the God of the gaps," and pointed out the most obvious problem with it:
How wrong it is to use God as a stop-gap for the incompleteness of our knowledge. If in fact the frontiers of knowledge are being pushed further and further back (and that is bound to be the case), then God is being pushed back with them, and is therefore continually in retreat. We are to find God in what we know, not in what we don't know.
So accounting for a phenomenon using some not necessarily religious, but non-scientific, explanation is basically nothing more than the argument from ignorance; "we don't yet know how this works, so it must be beyond science to explain."
Emphasis on the word "yet."
Take, for example, the bleeding polenta of Padua.
In 1819, there were reports of what some were calling a miracle and others a work of Satan -- the appearance of what seemed to be drops of blood in polenta, bread, and other starchy food. Whatever it was did look convincingly like blood, as you can see from the above photograph. Italy in the nineteenth century was a devoutly Roman Catholic country, and the phenomenon was considered a "sign" (of what, depended upon whom you asked; some thought it was a harbinger of the end of the world, unsurprising considering how often this claim still comes up).
But a chemist at the University of Padua, Bartolomeo Bizio, firmly believed that there had to be a natural, rational cause for the spots. He obtained samples of the red-stained food, and very quickly discovered two things: (1) if he put a drop of the red material on a sterile dish of starch, it rapidly developed red streaks as well; and (2) when he looked at some of it under a microscope, he saw cells -- but not blood cells. Whatever it was might have the same color as blood, but it wasn't blood.
It was, in fact, a bacteria, which Bizio named Serratia marcescens -- the genus name after Florentine biologist Serafino Serrati, and the species name from a Latin word meaning "decay." The red color comes from an organic compound called prodiogiosin. Serratia marcescens has been found to be a more-or-less ubiquitous bacteria in soils and on moist surfaces -- it's responsible for the pinkish color that sometimes shows up in spoiled food and around the edges of unscrubbed sinks and drains.
It's a simple example, but it does show how "it happened because of something supernatural" is not really an explanation at all. It is, in fact, a way to stop thinking. Bizio started from the standpoint of "let's assume this has a rational cause," and it was only because that was his baseline assumption that he was able to take the step forward into understanding it.
Now, don't misunderstand me; it's not that I'm sure that science can explain everything, and it's certainly not because I think science has explained everything. It's more that before we jump to a paranormal answer, we'd better make sure we've ruled out all the scientific ones first. Because in the past two hundred years, the other magisteria have gradually shrunk as science has explained more and more of the universe.
As the inimitable Tim Minchin put it: "Throughout history, every mystery ever solved has turned out to be -- not magic."

Chutzpah
As always, Yiddish has a word for it, and the word is chutzpah.
Chutzpah means extreme self-confidence and audacity, but there's more to it than that. There's a cheekiness to it, an in-your face, scornful sense of "I dare you even to try to do something about this." As writer Leo Rosten put it, "Chutzpah is the guy who killed both of his parents and then appealed to the judge for mercy because he's an orphan."
The reason this comes up is, unsurprisingly, Mark Zuckerberg, who raises chutzpah to the level of performance art. This time it's because of his interview last week with The Verge, which looked at his company Meta's embrace of AI -- and his sneering attitude toward the creative people whose work is being stolen to train it, and without which the entire enterprise wouldn't even get off the ground. When asked about whether this was fair or ethical, Zuckerberg basically said that the question was irrelevant, because if someone objected, their work was of little worth anyhow.
"I think individual creators or publishers tend to overestimate the value of their specific content in the grand scheme of this," Zuckerberg said. "My guess is that there are going to be certain partnerships that get made when content is really important and valuable. But if creators are concerned or object, when push comes to shove, if they demanded that we don’t use their content, then we just wouldn’t use their content. It’s not like that’s going to change the outcome of this stuff that much... I think that in any new medium in technology, there are the concepts around fair use and where the boundary is between what you have control over. When you put something out in the world, to what degree do you still get to control it and own it and license it?"![]() |
