Blood-Brain Barrier: Stories from the Borderlands of Science, Story 7. Olga the Science Cat

This collection of short stories by Stan Rice, who is also the author of nonfiction books of popular science and science novels, takes the reader to the frontier between science and worlds of the impossible (see his author website here). Readers of my science blog will appreciate the creative telling of scientifically impossible stories; readers of my religion blog will appreciate the question of whether, even if these things were possible, would they be good?

 

The stories in this collection are The Man Who Could Work Miracles, Light Apparel, Flow of Blood, Wisdom Builds Her House, Rock Bunnies, Entropy (all reviewed earlier), Olga the Science Cat (reviewed here), Doghouse, and Fresh Air.

Rice wrote a book about the scientific method. But how much better it would be to have the scientific method explained to you by a cat! No, not a talking cat like the gorilla in Daniel Quinn’s Ishmael. In Olga the Science Cat, the cat com-mew-nicates by grabbing items and leaving them on the floor or table in such a way as to answer human scientific questions. After Olga helps the kids with their science fair projects, she helps save the little girl’s life by dragging a hamburger sack from the garbage, with its evidence of salmonella poisoning.

Rice is not known for juvenile literature. This is the only piece of juvenile literature I have seen from him.

The Ecology of Fiction Publication, part one. Publishers vs. Kindle

I have frequently written on this blog about my non-fiction publications. But I have also written a huge amount of fiction. My fiction would be very hard to sell to commercial publishers, because I have so much science in them. That is exactly the reason that readers of this blog would like them, and commercial publishers would not.

I am no amateur in fiction writing. I have been writing fiction for decades, often rewriting the same story or novel over and over until I get it as good as it can be. In the process, I have removed whole chunks of text that I originally thought were really good but which I admitted would not advance the plot and might, however well written, cause the reader to give up.

But I have almost no fiction publications—just in a couple of minor literary journals that no longer exist. I have earned a grand total of $25, which I sent to a writer and environmentalist who, unlike me, had no steady employment. So the question arose, decades ago, how should I publish my fiction?

The days of submitting manuscripts “over the transom” ended decades ago. Now, to approach an editor of even a small press, you have to be represented by an agent. When I started writing fiction, agents were actual people, and they sent me personal responses. But now, the prospective fiction writer seldom gets any response whatsoever, and if so, it is a form letter. I now have the suspicion, in the modern age of artificial intelligence, that agents almost never read submissions, because they already know what they are going to send to publishers: the works written by their friends, themselves under a different name, or by an AI program they have installed. They claim to be looking for new talent, but I simply do not believe it. In fact, agents may actually themselves be artificial intelligences. They may have their photos on the agency website, but they may not be actual people. An agency can leave the entire process—choosing which manuscripts, if any, to represent, and then sending them to editors—to artificial intelligence. I have encountered a grand total of about five agents out of hundreds who have given personal responses that indicate that they are human. An AI bot can write fiction that is as marketable as that written by most human authors. I guess what I am saying is that getting a fiction agent for a commercial publisher is practically impossible. I have been told this by many authors—you know, the ones that spend their time and money going to writers’ conferences.

For many years, an attractive alternative has been to self-publish on Amazon. Gone are the days of vanity presses, where the author pays for a few hundred copies of the book to be printed, and then the author has to figure out what to do with them. These are the days of Amazon, in two ways:

First, no commercial publisher can afford to do “print-on-demand,” because there has to be a minimum print run of at least a thousand books each day to justify the costs of printing. But Amazon can do it, because they sell so many books. It does not have to be a thousand copies of the same book. Print-on-demand is one of the Amazon options. If just one person wants your book, they can get it.

Second, e-books cost very little to produce. A Kindle book can be produced and sent to customers with very little cost, except for maintaining the servers. Once again, if just one person wants your e-book, they can get it.

Kindle publishing is rather clumsy. If it is just text, as in most novels, it works fine. But I have never seen a really satisfactory illustration in a Kindle book. It usually ends up really small and illegible.

The advantages of Kindle books are astonishing. The software, at least now, is relatively simple. You provide a cover illustration (just the front cover), a document with the whole book in it, financial information, the jacket blurb (which will show up on the Amazon site), etc. You can do it all yourself. If you mess something up, you will get an email telling you what to fix. The best part might be that the author gets to keep 70 percent of the money. In contrast, a commercial publisher offers 10 percent, which must be split with an agent. This would mean an author gets 8 percent. A hundred books (@$5.00) generates $500, of which the author gets to keep $350. From a commercial publisher, you would get $40.

Now, for the ecology of book publishing. It is like a tree or bush disseminating its seeds. There are lots of ways of doing this. A tree could produce a few, large seeds, inside of fruits that animals want to eat; or a lot of small seeds, that blow away in the wind. Wild plant species use both options, just like a writer could use the agent/publisher option or the Amazon option. There is, in the world of publishing just as in seed dispersal, no single correct way of doing it. I spent decades on the agent/publisher route, and am now ready to try the Kindle route. My first Kindle novel just came out today.

What you don’t want to do is to publish online and then ignore all publicity. Fruits and seeds dispersed by animals put a lot of expenditure into publicity—that is, into attracting animals to disperse them. Publicity—that’s what the next essays are about.

The Teachable Moment: A Feather

When I retired from college science teaching, I thought I would continue teaching in an informal capacity. I have continued to write books and blog essays (you are reading one). I also have two grandchildren who are at the discover-the-wonder-of-the-world stage of childhood. I thought that I would impart to them fragments of my vast knowledge about the world.

Of course that is not exactly how it worked. They (ages 7 and 5) have a nearly unlimited capacity to ignore whatever anyone is saying to them, even mid-sentence. What I had to do instead was to wait for a teachable moment, when they showed spontaneous interest in something, or could be led into it.

They were playing with their nature treasure boxes, which included pigeon feathers. (Pigeons make up most of the bird biomass of Alsace.) These particular feathers were fine and delicate. I said I had a story about feathers that my mother (their great-grandmother) told me. Lena immediately said that people used to dip quills in ink to write. But, I said, they had pens by the time my mother was a little girl. Instead, I told them about how my grandfather, their great-great-grandfather, used a turkey feather to put medicine on my Mom’s face. This is not what they were expecting.

My mother, as a little girl, got into the natural world in Oklahoma by brushing poison ivy (Toxicodendron radicans) against her face. Of course, her face swelled up dangerously. Her father went to town in his wagon (other people had cars, but not him) to get medicine, which was probably some ointment with mercury or something in it. He used a turkey feather to gently apply it to my mother’s face. It was important to not break the skin, which would leave a scar, and also allow bacteria to infect the skin. The in my granddaughter’s box opened up a discussion of infection.

And of allergies. Poison ivy is not poison. Urushiol, found also in poison oak (T. diversilobum) and poison sumac (T. vernix) is not poisonous. It just provokes a massive allergic reaction in most people. But not in everyone. Some people do not react to urushiol at all. One of the main characteristics of allergies is that they differ from one person to the next. I told them the story of the girl with a peanut allergy who died after her boyfriend ate a candy bar and kissed her. (I heard this on the news, but have been unable to trace a source for it.) Most of us do not have peanut allergies. But Lena knew a distant cousin, on the French side of the family, who did.

Urushiol does not cause allergic reactions in all mammals. Deer eat the leaves, and squirrels eat the berries. Horses can eat the leaves. The urushiol comes out in their sweat and you can get it on your legs from riding the horse. I do not know if dogs and cats can get poison ivy, since they are primarily carnivores; but if your dog runs around in poison ivy and then runs up to you, beware of giving the dog a hug.

But it was not just science education; it was also cultural education. An Asian species, T. vernicifluum, produces sap that is used in the production of Chinese and Japanese lacquerware.

All this biology education, just from a feather in my granddaughter’s nature box. She showed genuine interest and surprise. I could easily have missed this teachable moment, had I not been watching for it.

The Stars in their Courses

This is from an email I wanted to send to the office of the Oklahoma State Superintendent of Public Instruction, Ryan Walters. However, neither he nor the department had any way for the public to contact them. They hand down their decisions from an undefiled lofty summit, without any input from the public they supposedly represent.

Walters has become infamous for mandating that all Oklahoma Public School classrooms teach from the Bible, and he means this literally. He has sought bids for the state to buy 55,000 Bibles to distribute among Oklahoma classrooms. But to my knowledge he has not provided any guidance about how to do this in a manner that is acceptable to him, personally.

I pushed the limits of truth in this letter. I retired from public university teaching in Oklahoma. My university classroom would not, itself, have been required to teach from the Bible. I taught biology and evolution, not astronomy, but there was some cosmology and astronomy in my courses.

“Dear Superintendent Walters,

“I have been an Oklahoma science teacher for many years. Among the subjects that I have taught are biology and astronomy.

“In order to comply with your order, I would have to use the Bible as the basis for astronomy. I assume from what I have heard that you are a creationist who accepts the recent miraculous creation of the Earth. But that is not what I am writing about.

“Instead, my understanding is that even creationist astronomy does not include astrology, that is, the belief that stars and planets directly influence human affairs.

“Imagine my surprise when I re-discovered Judges 5:20. (I have read the Bible twice, but I forgot about this verse.) Judges is a book, which you would consider historical (it is not psalms, proverbs, or prophecy) about the Israelite conquest of Canaan. This passage is from the victory song of Deborah (a woman army leader) and Barak about a recent Israelite victory over the Canaanites. It reads, “From heaven fought the stars, from their courses they fought against Sisera.”

“Am I supposed to teach that astrology is, under some circumstances, true? If so, perhaps the state should also require classroom horoscopes and, if so, your department would issue the official horoscopes for public school use.

“If, instead, you consider this passage to be poetic allusion, then I would have no difficulty with this passage. However, how is a public school teacher to decide which Biblical passages are literal and which are poetic allusion? Your department should also issue official guidelines about this as well, perhaps an official state manual for Bible interpretation.

“Could you help me out in my confusion?”

There is much legal uncertainty about whether Walters will have to rescind his command for public school Bible instruction.

The Pleasure of Finding Things Out

This is the phrase that celebrity physicist Richard Feynman used to describe the joy of scientific research. But it also describes the joy of science education. Feynman was as brilliant of a scientist as you could hope to meet, and to him mathematical equations were as obvious as the nose on your face. But he knew very well that science education did not consist of learning piles of facts. He knew it was a matter of joy: professors and students alike should share this joy. This is what I always tried to do as a science educator, even to the extent of trying out what some colleagues thought of as stunts.

This is the reason that Bill Nye the Science Guy is more popular among people in general than any professor could hope to be. Professors try to impress their colleagues; but Bill Nye’s audience is ordinary intelligent people.

 

Jamy Gormaud is France’s answer to Bill Nye. He started off as a reporter, then discovered the joy of science—just as Carl Zimmer and David Quammen started off as fiction writers and found their calling in science writing. Today, with his YouTube channel, Jamy uses humor—a lot of it—to communicate not only science but also history to a large audience. My wife and I started watching his videos in order to learn French, by slowing down the videos and reading subtitles. But I appreciate his joy of science. In one of his books (Mon Tour de France: Des CuriositĂ©s Naturelles et Scientifiques) he has assembled a tour of France to see scientific curiosities. Several dozen videos later, he is still one of our favorite video hosts. Jamy describes the pleasure of learning new things as “la connaissance qui soulève l’esprit” (knowledge that lifts the spirit). He practices “la vulgarisation de la science.” Vulgarization is not a bad word in French, although American professors and writers hate to be accused of vulgarization. It just means making science understandable and interesting to non-specialists.

He takes his readers to old places to see new things. He starts his book in the marshlands of northeastern France mainly because he saw some great sunrises there when he was a kid. This chapter is about why sunrises (and sunsets) are red. Maybe you know why, and maybe you don’t. My answer was mostly right.

Sunlight is intensely white, which results from the mixture of all visible wavelengths of light. But when sunlight encounters atmosphere, it scatters. Blue wavelenths, at one end of the spectrum, scatter more than the others, which is why the sky around the noontime sun on a clear day is blue and the sunlight itself is yellowish: the sunlight is white minus some of the blue color. When sunlight has to travel through more of the atmosphere, as when it comes in at an angle at sunrise or sunset, not only do the blue wavelengths scatter but also the others, except those at the red end of the spectrum. If you did not know this, you might have felt your brain grow a little bit right then. Thanks to Jamy, and maybe to some outstanding science teacher you may have had in the past.

Jamy, and other good science educators, also draws in perspectives from outside of science. It was Isaac Newton who explained that white light is all the rainbow colors mixed together. We do not perceive it as a range of colors, but as bands of color. It turns out, for reasons I explain in my book Scientifically Thinking, that our brains create the illusion of bands of color, which helps our brains make sense of the world. But, Jamy wondered, why did Newton say there were seven bands of color? Clearly there are bands, but can you really see seven bands? Violet, indigo, blue, green, yellow, orange, and red. Long before Newton, Robert Boyle had written that a rainbow has five bands of color. Jamy explained in his book that Newton was very religious—he wrote more pages about religion than about science—and to him seven had great Biblical significance. That is, Newton had a little bit of religious illusion even in his hard scientific observations.

He must be very satisfied in his work. To the extent that my videos fulfill the same role as his, I am satisfied. Even though I have retired, I continue to be a science educator, in the tradition of Jamy Gourmaud.

My New Science Education Career

As Fluff told you in the previous essay, I have moved to Strasbourg, France. I was really relieved to get here, and could not have done it without extensive help from my daughter and French son-in-law. They had almost everything ready for us, and are helping us with the rest.

I joked that I was going to be a full-time grandpa. But, as it turns out, that is mostly what is happening. I had fantasies about traveling in Europe, at least in the “Schengen zone” where the only thing you need is a European passport. Not all Schengen countries are in the European Union, with a common currency, but they erect no barriers to one country’s approved residents traveling to another. I thought I would go to see all the natural areas, and continue posting videos and essays about the natural landscape of France. But I am having plenty of challenges even without leaving Strasbourg. Just learning our way around, establishing a bank account, learning to use the tram, and buying a few things keeps me and my wife occupied when I am not reading, writing little essays like this, or staying with my grandkids. The cultural transition I am now experiencing will take several months. Then I can think about travel.

That is my new science education career: teaching my grandkids about the wonders of science. There are a lot of things that I have taken for granted ever since I was a little child, such as the fact the Earth is roughly spherical; it rotates at an angle; it revolves around the sun, and this accounts for the seasons. I just assumed everybody knew this, but my grandkids will have to learn it from me, or from school, hopefully both. And to do this, my wife and I just bought them a globe, nearly identical to the one that I had when I was a child. The fact that the Earth turns, rather than the sun moving across the sky, is not something that you can just see from the ground. It is something you have to deduce from evidence. I feel anew the sense of discovery I had as a child.

The globe also has raised mountains, which will allow me to show the kids how Tibet differs from France in more ways than one. It will also allow me to explain rain shadows. I can also explain the Gulf Stream, which is why Strasbourg, at 48 degrees north, has a moderate climate.

I assumed that everyone knew that when it is winter in the Northern Hemisphere, it is summer in the Southern, and vise versa. But apparently this is not true. A wild right-wing commentator, Dinesh D’Souza, was so angry at global warming science that he would grab at every bit of information he could find to discredit it. In a recent year, he heard that Australia had snow in August. D’Souza proudly declared, how can there be snow in August if there is global warming? He did not know August is winter in Australia. This is something my grandkids will know before they finish elementary school. D’Souza was briefly the president of the King’s College, a fundamentalist Christian college in New York. He was forced to resign, not for ignorance, but for the fact that he had an affair with the wife of one of the administrators of the college.

The only problem with the globe is that it is labeled in Italian. But here in Europe, no matter which country you are in, you are surrounded by other languages. Italy is only a few hundred kilometers south, closer than Spain. So this is not really a problem.

And this is just the first step. Within the next year or so, we will get the grandkids a microscope (surprisingly cheap) which will open new worlds to them, I hope, as it did for me. And a music synthesizer. I hope they will grow up learning music as a language and a form of expression, not just as a pleasant (or annoying) background to other activities. A telescope? Maybe not, since, so far, every night and most days have been cloudy, thanks to the Gulf Stream.

I even thought about making videos and writing essays in French about science and nature. But it will take a long time for me to have enough fluency in French to do this. I will never be another Jamy Gourmaud. I will just never speak or write French well enough. The French language is the subject of my next essay.

Testing a Hypothesis: Sometimes It's Your Only Choice

Plants are dynamic beings that respond continuously to their environments. (Continuous means without interruption, while continual means at recurring intervals.) That is, plants adjust their growth, and even their movements, all the time, day and night, all year.

One fascinating example is called nyctinasty. This is where a plant raises its leaves up, or opens its leaflets, during the day, and lowers the leaves or closes the leaflets at night. Makes sense. During the day they need the light for photosynthesis, and at night they don’t.

Problem is, most plants don’t bother opening and closing, or raising and lowering, their green surfaces. The leaves face the sky in the day, but at night, most plants just leave them where they are. Only a few plants raise and lower, or open and close, their leaves. Examples include the velvetleaf Abutilon theophrasti and many members of the bean family, including the mimosa tree Albizzia julibrissin. This photo shows mimosa leaves folding up for the night, even before sunset. Each mimosa leaf consists of leaflets, each of which has lots of little pinnules. It is, as you can see, the pinnules that close up, and they do so by moving upward.


Why should a plant fold up its leaves at night? Nobody knows, but there is plenty of speculation. Some think it protects the leaves from nighttime rain; others say it hides them from bugs. The most likely reason is that the night sky can be very cold, any time of year, even if the air is not. This could cause the leaves to get too cold during the spring (or fall, but autumn leaves have little value to a deciduous plant that is going to drop them anyway). This was Darwin’s idea, and (working with his son Francis) he made the observations to support (but not to prove) it. Of course, this doesn’t explain why the other plants don’t do this.

This is what mimosas do during under regular conditions: they raise their pinnules each sunset and lower them each sunrise. They do so by the alternate swelling and shriveling of little sacs called pulvini (singular pulvinus). But what I wanted to know was, is the pulvinus on the top side of the pinnule stalk, in which case the pulvinus swells to push the pinnule down, and the pinnule moves up when the pulvinus shrivels; or is it on the bottom of the stalk, in which case it pushes the pinnule down when it swells, and the pinnule moves up when the pulvinus shrivels. The swelling of the pulvinus requires energy; the shriveling does not. Therefore, I wondered, does the pulvinus push the pinnule up at dawn, or does it push it down at sunset?

I looked in the scientific literature and all over the web, and (at least in 2018) could not find an answer to this simple question. So, in desperation, I decided to test a hypothesis myself. And I did so without any fancy equipment or a research grant.

Nyctinasty is not the only process that can make a pulvinus shrivel. Drought can also make a pulvinus shrivel, just as it can make every other cell or structure in a plant shrivel.

There happened to be a drought going on in Tulsa, where I live, in summer 2018. So I went looking for a mimosa tree that was experiencing drought. I had to go up on Turkey Mountain (which is a hill and has no turkeys) to find one. As you can see from the photo, a mimosa leaf experiencing drought during the day raises its pinnules before they start to curl up. This means that the pulvini must be on the top of the pinnule stalks. The pinnules lift up because of tension in the cellulose fibers in the cell walls, unless pulvini push them down.


I wanted to know the answer to the question, but I found enjoyment in answering the question in a way that anyone can do, even without a laboratory.

Another question that you might wonder about is this. After you exercise, of course, you breathe faster, and this helps your body to get rid of carbon dioxide that has built up in your blood. But does each breath have more carbon dioxide? To answer this question, all you need to do is to blow bubbles in slightly basic water. The water should contain some phenolphthalein, which turns pink under basic conditions, and turns clear in acid conditions. If each breath has more carbon dioxide (which becomes carbonic acid in water), then the phenolphthalein should turn clear sooner when you blow bubbles in the water right after exercising than when you blow bubbles in the water while rested. You can answer this physiological question, about lungs and carbon dioxide, without any equipment other than two glass jars, a couple of straws, and a little phenolphthalein. (You can’t just walk into the drug store for phenolphthalein, but it is not a controlled substance. You get it from science education supply companies.) If you can’t afford a carbon dioxide measuring device, you can test the hypothesis in a cheap and easy fashion.

These are actually experiments. In the case of the mimosa, it is a natural experiment: nature imposed the drought on the plants. In the case of breathing, the experiment compares the treatment (breath after exercise) against the control (breath while resting).

And it’s fun, too. Students like it. If you are an elementary school teacher, you can do the bubble experiment in your class.

There are probably lots and lots of questions that you wonder about and for which you cannot find an answer. Rather than to give up, try finding the answer by some simple observation or experiment.

Has the Pandemic Made Us Appreciate Science?

 

No.

One would think that the pandemic would have made Americans want to learn more about disease and health, about how to minimize the spread of disease by means of vaccination, social distancing, etc. In fact, this is what science writer Robin Marantz Henig said in the November 2020 issue of National Geographic: “Maybe the pandemic will persuade even the skeptics how crucial scientific discovery is to human flourishing.”

At the time Henig wrote this, it seemed so inescapably reasonable. But this has turned out to not be the case. The surge in covid cases in America, the great majority of them among the unvaccinated, has only strengthened the anti-science fervor among many Americans. About half of Americans disregard science, and many of these openly detest it. Rather than acknowledging that masks slow down the spread of covid, some states not only do not have mask mandates but have made these mandates illegal. Here in Oklahoma, it is illegal for schools and other state entities to require measures that protect either children or adults. It is difficult to appreciate the depth and scope of the hatred that many Americans feel toward science, whether it is the study of how diseases spread (epidemiology), or any other branch of science.

Right now, as shown in this graph from a French news website, America is leading the world in the number of covid deaths per day. Brazil used to be the leader, and Indonesia was briefly, but America has gone back to being the world leader in covid deaths per day.

As a science educator in rural Oklahoma, I feel quite despondent right now about the hostility of my neighbors toward any kind of scientific evidence about anything. I used to be inspired in my work; now, I just count the days to retirement.

General Biology Education: The Same Old Same Old

 

There was a time when dozens of general biology textbooks flooded the college market. They were expensive to produce, but the market was huge. Students did not like buying them, since they were expensive, but they did it. Writing a general biology textbook that was widely adopted was a ticket to at least moderate wealth. From 1992 to 2006, I was on that yellow-brick road. But I never got to the Emerald City, as publishers canceled my contracts. (I got to keep the advances, though.)

This is no longer the case. One editor, who had once worked with me on the general biology textbook that never went to press, said the market had imploded. This is because the textbook itself is no longer very important. Is it well written? Are the explanations clear? Nobody really cares anymore. The most important things now are the online resources, such as homework and quizzes. I believed that my textbook, focusing on world issues, was the best-written manuscript, and I continued to believe it until the contract was canceled in 2006. I still believe it. But now nobody seems to care whether the book is well-written, and relevant to world issues, or not.

At the time I started, as today, general biology textbooks were almost all alike. They have an utterly predictable chapter order: The scientific method; cells, genetics and biotech, evolution, an overview of organisms, then ecology. Last, inexplicably, comes human anatomy and physiology.

One problem with this approach was that the instructors sometimes did not get all the way through the book, with the result that the very important ecological concepts, such as overpopulation and global warming, get overlooked. Students think that biology is all about memorizing the steps of mitosis and get no idea that their decisions about how to live, what to buy, etc., all have immense impacts on the ecosystem of the Earth. The most important concepts get left to the end and get lost. Two authors, Joel Levine and Kenneth Miller, disagreed, and published a textbook that began with ecology and ended with cells and molecules. But, at least on the college level, their textbook was not prominent in the marketplace.


My textbook took a very different approach. In my original chapter order, the book both began and ended with ecological concepts. The first chapters were about what happened to energy and atoms: sunlight, photosynthesis, the cycling of nutrients, etc., what is sometimes called autecology. Then came the chapters that worked their way up through the typical chapter order, until reaching ecology again at the end. This time it was about species interactions and ecological communities (often called synecology). I thought it was a brilliant, circular alternative to the typical linear approach, whether the standard cells-to-Earth order or the reverse Levine-Miller order. At first, one major textbook publisher liked it too. But as they did their market analysis, they found that my chapter order would not sell. They got me to change the outline of the book until, just before they canceled it, the chapter order was the same as everyone else’s. This company still does not have a general biology textbook. They figured they could not penetrate the market, especially with a book as unusual as mine.

This approach, imbedding cells-to-heredity into an ecosystem context, had been successfully used decades earlier, in the 1960s, in the “Green version” of High School Biology, prepared by the Biological Sciences Curriculum Study (BSCS) committee of the American Institute of Biological Sciences. I am not aware that this book is still in print; it may have last been in print in 1992. This version of the book began with something that many kids had seen—a rabbit hiding under a raspberry bush—and started asking questions about. Learning biology was, therefore, a natural outgrowth of instinctive curiosity. There is a good reason that this book remains one of the most famous in the history of biology education.

I had another original and, I thought, unique feature. I did not separate animal from plant anatomy and physiology. There were no chapters about the digestive system, the nervous system, and plant growth. Instead, I identified four common themes, then used both animal and plant examples of each. These are four problems every organism must solve in order to survive and reproduce:

 

  • Energy going into and out of the organism
  • Molecules going into and out of the organism
  • Internal integration of processes in the organism
  • Response to external events in the environment

It turns out that the famous evolutionary scientist George Gaylord Simpson had written a textbook (Life: An Introduction to Biology) that put animal and plant anatomy and physiology together: organic maintenance (procurement, use, transportation, excretion), internal organization, and responsiveness, including behavior.

My proposed merging of plant and animal topics was even more radical than my chapter order. Reviewers liked it but found it very inconvenient.

I have before me a textbook written by a prominent scientist, Gordon Orians. It is The Study of Life: An Introduction to Biology. His organization was different from everyone else’s, including the Levine-Miller organization and my own. His three themes were time, energy, and information.

  • Time: Evolution, and an overview of organisms in an evolutionary framework
  • Energy: Where it comes from, e.g., photosynthesis, and how organisms use it (and matter)
  • Information: How organisms are organized, e.g. DNA, how cells develop, how organisms perceive their environments, and social and ecological community organization.

At a conference of the Botanical Society of America in 1995, during a symposium that I helped organize, I heard Orians talk about this book, which was published and of which sample copies were sent to people and committees for their consideration. He said he had no adoptions. “I mean this literally,” he added. I think he should be proud of his book: it showed his integrated understanding of biology and its relation to the physical and human world. Its failure was caused by the market.

I can’t go around blaming biology teachers for getting into a rut of same old same old. They are busy. I certainly am. I barely have time to manage classroom duties, which now includes online interfaces. I certainly don’t have time to rethink biology education anymore. Looking back on it, I was surprised that (out of dozens of reviewers) so many of them were willing to reorganize their entire courses to accommodate my chapter order, had the book been published. I would have had, I estimated, about twenty adoptions. But since it takes a million dollars to bring a textbook to the market, no company could make a profit from this. I am not a failed idealist, but just a busy one, as I teach the same old same old order of topics. We would have to completely revise the lab schedule otherwise. The person who manages the labs does not have time to do this, nor am I willing to volunteer my time to do it.

And to most students it doesn’t matter. If they are willing to learn, and if the instructor is willing to make the concepts interesting and relevant, they will benefit immensely from general biology, no matter what the order it. Is one chapter order more logical than another? The students do not, and probably should not, care.

What Do You Do with Your Scientific Knowledge?

 Scientific knowledge is not just a private pleasure. It is something to be shared.

A few months back, in my other blog, I shared a story about a kind of Republican you seldom see any more, and I used my childhood optometrist as an example: Dr. James E. Miller of Exeter, California. I recently found an old newspaper clipping about him, from about 1972.

Dr. Miller loved astronomy. Not just looking at stars and planets, but understanding how far away they are and the motions of the planets. He must have felt the kind of excitement that Galileo and Copernicus felt when they realized that the story of the stars was very different from what they had heard when growing up. Dr. Miller was a conservative Christian, but I suspect he must have agreed with Galileo that the Bible told us how to go to heaven, not how the heavens go.

He bought a transparent celestial sphere, with planets and stars, not for his own enjoyment but to teach young people about the heavens. Two places he did this was at Boy Scout camps, helping boys earn their astronomy merit badges, and at SciCon, a science camp from back in the days when there weren’t very many science camps.


On two occasions this month, I got out my telescope (which I keep in my university lab) to look at Mars, Jupiter, and Saturn. I cannot see them very well, and my telescope is very difficult to use. Mars, though at its closest approach to Earth, just looks like a pink disc. I could just barely see Saturn’s rings. I invited students to come and look at the planets. Two of them did. The excitement was not in the quality of the image, but in the experience of having photons from the planets go straight to your retina. One of the students exclaimed, on seeing Saturn’s rings, exclaimed with great excitement, “I see it!”

I also asked the two students why Mars is red. The red comes from oxidized iron. On Earth, this usually means a reaction with oxygen. But Mars has no oxygen. What caused the iron to oxidize, that is, to lose electrons? I hinted it was something that an oxygen derivative largely shields the Earth from. It was the student who was not a science major who guessed right: UV radiation. The red surface of Mars is only a few centimeters deep.

On those evenings last week, I was doing what Dr. Miller did. And I’m pretty sure that I got a lot of my enthusiasm for all the rest of my science teaching from Dr. Miller.

The Ascent of Jacob Bronowski


I just finished reading a pre-publication copy of Timothy Sandefur’s upcoming The Ascent of Jacob Bronowski. If even I, a reader of many popular science books, have barely heard of Jacob Bronowski, you can bet that most people have forgotten him. But before there was Neil DeGrasse Tyson, before Stephen Jay Gould, before Carl Sagan, there was Jacob Bronowski (1908-1974) whose passion was to open up the minds of non-scientists to the power and beauty of science.


Bronowski’s work was based on a fundamental assertion of faith that I share, but which I sometimes question. It is that most people are smart enough to understand science, at least in its basic outlines, and smart enough to use the scientific mode of thought. This is the basis of my book, to be released in December, ScientificallyThinking. Bronowski’s gospel was to get scientists to speak clearly and simply to non-scientists and open their eyes to science. I believe that most people are smart enough to do this, but relatively few people really want to. Most people would rather sit in their backwater of ignorance and listen only to things that reinforce their lazy prejudices.

Bronowski (known to his friends as Bruno) was the perfect example of a Renaissance Man, that is, someone who is interested in everything. I first learned this term back about 1977 when a friend called me a Renaissance Man. I was a biology major who wrote novels, wrote orchestra music, and studied history and languages. Perhaps only a Renaissance Man (or woman) can make the connections necessary to bring people from all different modes of thought together. This was certainly Bronowski. An English child of eastern European immigrants, he started off as a poet. But he was also interested in mathematics, which led to statistics. (Statistics differs from pure mathematics because pure math deals with the certainties of deduction, while statistics tries to understand the messy reality of the world through induction. At least, that’s my summary of it.) His mathematical expertise got him involved in the effort for the Allies to win World War II, and later to make industrial production more efficient.

This mathematical work did not always lead Bronowski where he might have expected. Yes, he helped the Allies win World War II, but like many other scientists he was deeply disturbed by the effects of atomic bombs. He traveled in Japan after the bombs, and knew that the new power we had unleashed from the atom was completely disproportionate to any legitimate military goals even the best of countries might have. Also, his dedication to industrial efficiency led him on the ultimately quixotic quest to produce Bronowski Bricks from coal dust, sort of a fossil fuel version of charcoal briquets. The briquets reduced coal waste, to be sure, but they were very expensive to produce, and, according to Prince Philip, they looked like turds.

But Bruno’s wide knowledge, and being at the right place at the right time, threw him into the public spotlight in radio and television broadcasting. He produced, one after another, important science documentaries, culminating in his still-famous The Ascent of Man. He dabbled in lots of things at which he was not really skilled, such as writing a light opera libretto that was not very good (the music was by Peter Racine Fricker, who was on the music faculty when I entered the University of California at Santa Barbara). But he tried!

Science and art, said Bronowski, were both creative. Take, for example, Copernicus, who did some of the earliest work that proved the sun to be the center of the solar system, rather than Earth being the center of the universe. Copernicus had to imagine what the planets would do if he were at a central solar vantage point, but as an artist has to imagine what the final work would look like. Both scientists and artists test concepts: scientists, how well the concept explains the natural world, and poets, how well the poem expands our experience.

Another idea he had was that animals need intelligence in order to have free will. You have to be able to visualize possible futures before you can choose among them. Only humans can do this. I do not know if Bronowski actually solved the problem of free will, but he clarified it, at least for non-philosophers like me. He helped lay the foundation for the study of language acquisition. He said that only humans can make a sentence out of separate words, and then isolate one word and generalize about that one concept.

When he helped to start the Salk Institute, Bronowski moved to La Jolla, California. He would host scholars for discussions in his living room (where he also filed the final episode of Ascent). He was an inspiring partner for dialogue. While he knew everything about everything, he could make you feel brilliant even when he was saying you were wrong, according to more than one of his acquaintances.

Jacob Bronowski inspired us to think big, to see all human thought as a single fabric rather than as a collage of specialties. And he was an early inspiration for what we now call citizen science. They didn’t have the internet back then, but on his televised shows he encouraged viewers to send in postcards with their own scientific thoughts on them.

You can get a taste for the kind of spellbinding quality Bruno had by seeing this short YouTube clip from one of the Ascent episodes. Apparently when the BBC was filming this segment, they did not expect Bruno to walk out into the pond; this was extemporized.

I have a lot of different kinds of creative and intellectual output. I am not equally good at all of them, and am not world-class at any of them, as far as I can tell. But I can still do a lot of good with them. Bruno is my guiding light in this respect.
