Danny Dunn and the Homework Machine

Danny Dunn

Danny Dunn and the Homework Machine by Jay Williams and Raymond Abrashkin, 1958.

At the beginning of the book, Danny develops a device that allows him to do his homework and his friend Joe’s homework at the same time by using a system of pulleys and a board that holds two pens at once. (This seems like an unnecessarily complicated device, since he and his friend could accomplish the same thing just by sitting next to each other and talking over their answers as they both write them down at the same time, although Danny says that he plans to build a second pen board so Joe can work on their English homework at the same time as Danny does their math homework.) Danny thinks that it would save even more time if he could find a way to build a robot that will just do the homework for them, but Joe warns him to be careful because things often go wrong with his inventions.

Joe leaves to get more materials for their homework device, and suddenly, Danny is surprised by a tapping at the window, and he sees a girl’s face looking in at him. It’s surprising because Danny is on the second floor of his house. At first, he thinks that this girl who seems to be hovering in the air must be from outer space or something, but it turns out that she’s just an ordinary girl on a ladder.

The girl tells Danny that her name is Irene Miller and that her family just moved in next door. Her father, Dr. Miller, is an astronomer who will be working at Midston University. The reason why Irene is up on a ladder is that she’s built a weather balloon, and now, it’s stuck on the roof of Danny’s house. Unfortunately, she’s just discovered that her ladder isn’t quite long enough to reach the roof. Danny, who loves science, is intrigued by Irene’s weather balloon, and he helps Irene retrieve it by climbing out an attic window and onto the roof.

Danny shows Irene his device for doing homework, but Irene says it doesn’t seem quite honest because it’s basically like copying from someone else. Danny defends his idea, saying it’s not really cheating if the second person actually does know how to do the homework and would give the right answers anyway. He just sees it as a time-saving device. He also says that Professor Bullfinch, an inventor and physicist at the university, says that homework isn’t relevant to the learning kids do in the classroom. Danny’s father is dead, and his mother is Professor Bullfinch’s housekeeper, so Danny and his mother live with him.

Danny is surprised at how much Irene knows about science because he didn’t think girls would be into science. Irene says that there have always been female scientists, like Marie Curie, and she also wants to study physics. Although Danny has learned a lot from Professor Bullfinch, he’s a little intimidated that there are things that Irene knows that he doesn’t.

When Joe returns, he isn’t enthusiastic that Danny has made friends with a girl. When Joe is derisive about women and girls, Danny even defends Irene and how much she knows. Irene confesses to Danny that getting her weather balloon stuck on the roof wasn’t an accident. Her mother had already talked to Danny’s mother, so she knew Danny was interested in science. She purposely got the balloon stuck on the roof to get his attention and give them a reason for meeting. Joe uses that as part of his assertion that women are trouble.

Irene joins Danny and Joe’s class at school, and she starts making some other friends there. There is one boy in class, Eddie, who seems to have a crush on Irene. She’s a little flattered that he thinks she’s pretty, but she begins to feel uncomfortable with his attention because he keeps staring at her. Danny explains to Irene that people call Eddie “Snitcher” because he’s always telling on somebody for things they do, seemingly out of spite.

When Danny invites Irene to come to his house for cookies after school, Professor Bullfinch surprises them by telling them that he’s going on a business trip, and while he’s gone, he’s going to let Danny take care of his new computer. The computer is called Miniac, which is short for “miniature automatic computer.” It’s much smaller than most computers of its time. During the 1950s, computers could take up an entire room. The Miniac is about the side of a large sideboard.

Joe asks Professor Bullfinch how the Minaic works, and he explains that they can ask it questions through a microphone. The computer prints out answers with an electric typewriter. Irene asks if they can ask it a question to see how it works, and she asks the Miniac a question from their homework. Joe is amazed at how quickly the computer answers the question, and Professor Bullfinch explain a little more about how computer work, with a memory unit that stores information. He says that facts are stored on magnetic tape. (This was true at the time this book was written, although 21st century computers are constructed differently, in ways that allow them to be made much smaller than 1950s computers. What he says next about the nature of computer intelligence is still true, although I’m going to have some things to say about AI in my reaction section.)

Irene marvels at how the computer seems almost like something from science fiction (for her time) and how amazing it is to have a device that can give you the answers to everything. Professor Bullfinch explains to her that’s not quite true, and that there’s something more amazing: the human mind.

It is only a kind of supertool. Everything in this machine is inside the human head, in the much smaller space of the human brain. Just think of it — all the hundreds of thousands of switches, core memory planes, miles of wire, tubes — all that’s in that big case and in this console — are all huge and awkward compared to the delicate, tiny cells of the human brain which is capable of doing as much as, or more than, the best of these machines. It’s the human brain which can produce a mechanical brain like this one. … The computer can reason … It can do sums and give information and draw logical conclusions, but it can’t create anything. It could give you all the words that rhyme with moon, for instance, but it couldn’t put them together into a poem. … It’s a wonderful, complex tool, but it has no mind. It doesn’t know it exists.”

Danny’s assignment while the professor is away is to feed data to the computer. The professor has laid out the information and code tables that Danny will need, although the professor says that Danny can add some extra information if he comes across something new and interesting in Scientific American or one of the other science magazines he reads. Irene asks if she can help with this task because she finds it interesting, and the professor gives her permission. Before he leaves, he warns Danny not to get too carry away with his enthusiasm. He knows that Danny likes to experiment, and sometimes, he gets carried away when he has an idea, without stopping to think first. The computer is a tool, not a toy, and the professor wants him to treat it as such.

However, a few days after Professor Bullfinch leaves, Irene has a question about their homework that Danny and Joe can’t answer because they also don’t really understand the subject. Then, Danny gets the idea of asking the computer about it. Inspired by how easily the computer answers the question, Danny suggests to the others that they use the professor’s computer as a “homework machine.” After all, it can answer questions and supply them with information, and Danny thinks he could even program it to write short compositions. Irene is a bit dubious about it, but Danny amends his idea to say that the computer would “help” them with their homework.

My Reaction and Some Spoilers

Advancements in Computer Technology

One of the interesting things about reading a vintage book like this that focuses on the technology of its time is seeing how things have changed and how people’s perceptions of technology have changed. The kids in this book are amazed by the professor’s computer, which is cutting edge for their time, although 21st century children grow up accustomed to computers in their homes that they are allowed to use. Modern children do use computers as toys, playing computer games, and they are also tools for doing homework.

However, even though things have greatly changed in the decades since this book was written, some of the issues surrounding the ethical use of technology are still concerns in the modern world. This story brings up the issue of how much a reliance on technology to do homework borders on cheating and keeps students from gaining the skills they’re supposed to use. This has become a major issue in modern education in the 2020s, with the rise of AI technology. In the story, Professor Bullfinch says that a computer cannot write poetry, which might get a smirk from modern readers because AI has achieved compositional writing skills. What I’d like to point out, though, is that there are still limits on that. As of this writing, the ideal way to use AI in writing is as a starting point for writing and research but not as a replacement for human writers or the human mind to edit and control the content of the writing. AI also uses human writing as the basis for its compositions, not writing everything from scratch:

“… an AI writing tool will gather information based on what other people have said in response to a similar prompt. The bot will search the internet for information about what you’ve asked it to write, then compile that information into a response. While this used to come back as clunky and robotic, the algorithms and programming for AI writers have become much more advanced and can write human-like responses. … AI writers are, so far, limited in their abilities to create emotional and engaging content. Humans, by nature, are storytellers. We have been since the beginning. Robots, however, are not. They are limited by what they’re programmed to do, and AI bots are programmed to gather information and make an educated guess about what you want to hear.”

(AI Writing: What Is It And How Does It Work?, July 2023)

Computers, even those in the 21st century, which are both smaller and more efficient than the ones from the 1950s, still rely on input from human sources to do anything. AI work is not original, it only builds on what humans have given it to use. In spite of the word “intelligence” in the name “artificial intelligence”, it still “has no mind“, as Professor Bullfinch put it. It’s literally artificially intelligent. It knows nothing independently of human beings, and one of the current problems with AI is that, although it can write convincingly and sound almost human, it not only does so only because it’s basing its writing on human writing that has been supplied to it but also, it has no idea whether or not anything it says is true or not. As the Microsoft article points out, it’s only using predictive technology to guess at what you want to hear and just tell you what you want to hear. It still takes a human being to reason out how much sense AI writing actually makes or whether or not it’s accurate.

One of the current problems with AI in the 2020s is AI hallucinations. Sometimes, AI seems to make things up that aren’t true at all because the way it processes information sometimes produces errors, and by itself, AI has no way of knowing when this has occurred. It has no understanding of the subject its writing about. It’s only attempting to predict and supply what it thinks the human who supplied the prompt wants it to supply.

“AI hallucination is a phenomenon wherein a large language model (LLM)—often a generative AI chatbot or computer vision tool—perceives patterns or objects that are nonexistent or imperceptible to human observers, creating outputs that are nonsensical or altogether inaccurate.

Generally, if a user makes a request of a generative AI tool, they desire an output that appropriately addresses the prompt (that is, a correct answer to a question). However, sometimes AI algorithms produce outputs that are not based on training data, are incorrectly decoded by the transformer or do not follow any identifiable pattern. In other words, it “hallucinates” the response.”

There are currently problems with students relying too much on AI to do both their thinking and writing for them, and even professionals who rely too much on AI tools to get through their work faster sometimes fail to notice when the AI writing says things that don’t make sense or are just blatantly untrue. The AI doesn’t know what’s true or not, it’s just telling you what it thinks you want to hear, based on information given to it, put together, and rearranged in its logic programming. Because it doesn’t actually understand the information fed into it, it has no idea when it gets the story wrong. Computers are faster at processing data than a human, but actual understanding of information is still entirely a human quality. A computer cannot understand anything on behalf of a human mind because it “has no mind” of its own to do the understanding.

There have been cases where professional lawyers who have relied on AI writing instead of doing their writing themselves have been sanctioned when AI hallucinations included information that was not only inaccurate but actually fictitious, citing court cases that never actually existed. The lawyers who received disciplinary action about this did not proofread the writing produced by AI, just trusting it to do all of their writing and thinking for them. Yet, the errors jumped out immediately when actual humans read the writing.

The more complex the writing is, the more the limitations of AI become apparent. AI can sound convincing in a short article (especially if you’re not doing any fact checking to see whether it’s talking about something real or not), but it isn’t always consistent or coherent in longer writing. The drama department of one of the local colleges where I lived put on a performance of a play written entirely by AI as a kind of thought experiment, and the results were hilarious. It was a mystery play, and the script was confusingly written. The AI had trouble keeping track of which characters were currently on stage and which were not, so actors who were not actually present in particular scenes had dialogue. At one point, when the detective was questioning everybody, he even talked to the person who was murdered, and the corpse responded. The play didn’t make sense because the AI doing the writing didn’t really understand the story it was telling. It just told a story in the pattern that was requested of it. It was, technically, a complete play, and if you gave it a cursory glance, it would have looked like a fully written play. It’s just that it had absent people and dead people talking. Perhaps at some point in the future, AI can do its own proofreading and learn to catch these types of problems, but for it to do so with the accuracy of an actual human, it would have to have a human level of understanding about the world and the subject matter it writes about. That is, it would have to have real intelligence, not just artificial intelligence.

This video from Wired on YouTube features AI and machine learning professor Graham Morehead from Gonzaga University, answering common questions about the nature of AI. In the video, he explains some of the differences between how AI “thinks” and how a human brain thinks, which help explain why AI can do some things that a human being would find pretty stupid. AI often thinks in terms of two-dimensional images as opposed to the three-dimensional world we live in as humans, and it doesn’t always understand the consequences of actions because, to AI, everything comes down to simple numbers and data as opposed to a physical world where actions have context and consequences.

Overall, I think this story did a good job of evaluating the differences between the human brain and the electronic brain at a point in history where the technology was relatively new and evolving. It also did a surprisingly good job of anticipating some of the developments and problems associated with the use of artificial intelligence, although the form it takes in this story isn’t quite what we’ve seen in the 21st century, and the kids in this story encounter an issue that modern students attempting to use AI to do their homework aren’t likely to encounter.

At the end of this story (spoilers), Danny and his friends come to realize, to their surprise, that they’ve actually been doing more homework than their classmates in order to make their wonderful homework machine function. They had to teach the machine the subjects they’re studying in order to have it do the assignments because the machine doesn’t innately understand the subject matter. The kids have to supply the knowledge base for the machine learning to function, and that ultimately takes more work and study for them than simply understanding the subjects in their own minds and just doing the assignments themselves. Danny’s mother and his teacher allow the kids to continue using the machine once Danny’s mother explains to the teacher how the process works so the kids can experience how a seeming shortcut can actually take more effort.

This is a little different from the 21st century AI tools, where someone else has already done the basic programming work, and students don’t have to actually understand the subjects themselves to use the AI tools. Of course, if the student doesn’t understand the subject matter of the assignment, there’s less chance that they’ll even notice when the AI produces an AI hallucination and says something that isn’t true or doesn’t make sense. There is an incident in the book where the computer messes up and outputs something that makes no sense, and the kids have to figure out why it did that.

The kids also consider the issue of whether or not using the machine to do their homework is cheating or not. Irene has serious reservations about it at first, and their teacher and some classmates think it gives them an unfair advantage when they find out. Danny, on the other hand, defends it, thinking of the computer as just a time-saving tool, like a typewriter, although the computer is doing more for them than a typewriter does. Danny is only focused on the idea of saving time so he can do things other than homework because he’s confident in his own ability to understand the academic subjects and thinks that practicing his skills or proving his knowledge through homework is a waste of his time.

The only reason why the teacher agrees to let them continue using the computer is that Danny’s mother figures out before he does how much extra work he and his friends are doing to teach the computer how to do their homework. This becomes obvious after the teacher gives them a special assignment, beyond what was covered in class, so Danny and his friends have to work extra hard and spend far more time to understand the material themselves and then teach the computer to understand it well enough to do the work. The first assignments weren’t so hard for Danny and his friends to teach the computer how to complete because the kids are at the top of their class, and they do know the material. However, the more difficult the assignments get, and the less familiar they are with the subject matter, the harder it gets to program the computer to handle the assignments. This exposes the flaws in their system and highlights the need for them to understand the material themselves rather than depend on the computer to do their work for them or even necessarily do it more efficiently. The great use of computers is to do tasks more efficiently, but that depends on the task and whether or not the computer has accurate instructions and an efficient knowledge base to draw on to do it. Building the programming and the knowledge base takes the work of a human mind that knows what it’s doing and is willing to put in the effort to do it correctly and to troubleshoot errors.

School in the 1950s

In this book, we get a glimpse of school in the 1950s. Something that stood out to me was when the teacher mentions that the class sizes have grown considerably in recent years, meaning that she has less time to work with individual students than she used to. This was a real problem in the 1950s, due to the effects of the Baby Boom. This generation of children was much larger than previous generations, so there were shortages of teachers and class space, and teachers and students did complain that students got less individual attention. (This documentary on YouTube shows some of the overcrowding.)

The focus on science and technology in the Danny Dunn stories is also important to the 1950s because that was the beginning of the era of the Cold War technology race, exemplified by the Space Race. The capitalistic United States and its allies competed against the USSR and its allies for world supremacy following WWII, and one of the ways they did that was by trying to develop superior technology and technological skills. This need to compete in the areas of science and technology led to changes in the US public education system, emphasizing the skills that we would call “STEM” skills today (science, technology, engineering, and mathematics). Echoes of those changes still influence the way we think about education in the 21st century.

This technological and scientific focus also influenced children’s entertainment, as adults tried to encourage children to take an interest in science and technology. The Danny Dunn series is one example of this, showing children who are interested in science and new inventions and portraying them as fun and exciting. Another example was the educational tv show Watch Mr. Wizard, which was being broadcast at the time the Danny Dunn books were written and published. Watch Mr. Wizard featured the title character performing experiments in his laboratory and demonstrating scientific concepts to child visitors. It was very popular, and in the 1950s, there were science clubs for children based around this show. This show also helped inspired new generations of shows with a similar premise, such as Bill Nye, the Science Guy, which was popular when I was a kid.

The Mystery of the Goldfish Pond

Three Cousins Detective Club

#15 The Mystery of the Goldfish Pond by Elspeth Campbell Murphy, 1997.

Timothy’s father wants him to sing at his boss’s retirement dinner. The boss’s wife heard Timothy sing once with his choir, and she wants him to sing a special song for her husband at the start of the dinner. His cousins are invited to come along so he won’t be the only kid there. Timothy doesn’t really want to do the singing, but his parents convince him to do it anyway because the boss’s wife is so fond of him and his singing.

Timothy’s father hopes that the dinner will go well because the boss has been worried about the possibilities of competitors getting their hands on information about their new product. Earlier, the boss temporarily misplaced an important memo about it, and he was worried that someone else got their hands on it.

Timothy’s song goes well, and after the dinner, the kids are allowed to walk outside in the garden while the adults listen to a series of speeches. The gardens outside the banquet hall are beautiful, and the kids start to enjoy themselves. Then, they accidentally overhear a couple of adults talking. They can’t quite catch everything they say, but something strange is going on, and something secret is hidden somewhere in the garden.

The theme of this story is Proverbs 11:13, “No one who gossips can be trusted with a secret, but you can put confidence in someone who is trustworthy.”

The book is available to borrow and read for free online through Internet Archive.

My Reaction and Spoilers

The crime that the adults were plotting involves the theft of information. The kids have to figure out the parts of the conversation they couldn’t hear clearly to figure out where the information is hidden. I thought that the clue the children try to figure out was fairly easy. Part of the conversation the kids try to figure out sounds like “-ake -urtle”, and there aren’t many words that sound like “-urtle.”

The boss’s wife seemed eager for the children to go outside, into the garden, and tell her about it later. The kids wondered why she seemed so eager for them to go outside and what she was hoping that they would tell her afterward. It sets the stage for the kids to expect that something unusual or mysterious might happen, which proves to be the case when they overhear the important conversation. The boss’s wife says later that she suspected something might happen because she knew her husband was worried about people stealing company information, and she realized that this dinner would be a convenient place to hand it off to someone.

We never learn exactly what kind of information or new company products the adults were concerned about. We also don’t know exactly who was trying to steal the information or what happens to that person later. The part that the children care about is that they were able to stop the hand-off of the information.

The Mystery of the Eagle Feather

Three Cousins Detective Club

#9 The Mystery of the Eagle Feather by Elspeth Campbell Murphy, 1995.

Timothy is excited because he has a chance to meet his pen pal, Anthony Two Trees, for the first time. Anthony is a Native American, and he will be dancing at a powwow. Timothy’s cousins get to come along on the trip, too.

Soon after they arrive, though, they learn that someone has been taking pieces of the dancers’ costumes, like fans or headdresses made of eagle feathers. Who could be taking the costume pieces and why?

The costume pieces and the eagle feathers they contain are very expensive, and the kids realize that the thief might be thinking of selling them. It is illegal to deal in eagle feathers because eagles are an endangered species. Even the Native American dancers have to write to the government in order to get eagle feathers for their costumes from eagles that died in zoos. Therefore, the costumes are expensive and require a lot of effort to put together, and losing them is a real blow. The rarity and cost of the feathers might prove to be a temptation to a thief.

The theme of the story is self-control.

The book is available to borrow and read for free online through Internet Archive.

My Reaction

I wasn’t sure if I was going to like this story. I understand the fascination kids have with Native Americans and their costumes and dances. I felt like that when I was a kid, too, but there’s also an element of cringe to it. The cringiness comes from kids (and even adults) who get wrapped up in the fascination of the appearance of other people’s traditions and treat them more like playing dress-up than traditions with deeper, underlying meaning and significance or depicting Native Americans as being stereotypes from old movies and books rather than real, living people.

Fortunately, I was pleased at how this story shows that Timothy’s friend, Anthony, is a regular boy who shares his interest in baseball. They emphasize that Native Americans don’t live in tepees any more, and they don’t treat the Native American characters like stereotypes. I enjoyed some of the facts the story provided about Native American dances and costumes, like the regulations regarding the use of eagle feathers.

The Mystery of the Silly Goose

Three Cousins Detective Club

#10 The Mystery of the Silly Goose by Elspeth Campbell Murphy, 1996.

As soon as they arrive home from their trip to the powwow in the previous book, the cousins are approached by Timothy’s neighbor, the snobby 13-year-old Lyddie, with another mystery. While they were out of town, someone went around the neighborhood, stealing lawn ornaments. Lyddie is concerned because her grandmother has come to live with her and her parents, and her lawn geese were stolen. One of the geese was the mother goose with a silly-looking bonnet on her head, and the others were her goslings. Lyddie’s grandmother is rather attached to the geese because they were a present from someone.

The three cousins don’t really like Lyddie because she and her friends are usually unfriendly and too concerned with being “cool” all the time. However, they feel sorry for her grandmother and agree to take the case. To their surprise, most of the lawn ornaments are actually pretty easy to find. They were hidden in some obvious places around the neighborhood. The only ones that are difficult to find are the geese. Who hid the lawn ornaments and why?

The theme of this story is Proverbs 24:3-4, “It takes wisdom to have a good family. It takes understanding to make it strong. It takes knowledge to fill a home with rare and beautiful treasures.”

The book is available to borrow and read for free online through Internet Archive (multiple copies).

My Reaction

Part of the mystery has to do with image, but it also has to do with sentimental attachment. Lyddie is very obsessed with image because she and her friends try so hard to maintain their cool image. Although she calls in the cousins to find the missing lawn ornaments, she only does it because her grandmother takes the loss of the mother goose so hard. Lyddie doesn’t see why the goose is so important, although she knows that her grandmother is attached to it because it was a present from someone.

The situation changes when Lyddie’s grandmother reveals the full story behind the lawn geese and her own understanding of the situation. Lyddie cares for her grandmother, and she comes to see the geese in a new light once she understands why they matter to her grandmother. It’s not the value of the geese, and it’s not about how the geese look. It’s all about the person her grandmother associates with them. Fortunately, Lyddie’s grandmother is a very understanding woman, and when the lawn ornament thief explains the issue, they work things out to everyone’s satisfaction.

The Mystery of the Haunted Lighthouse

Three Cousins Detective Club

#7 The Mystery of the Haunted Lighthouse by Elspeth Campbell Murphy, 1995.

Sarah-Jane’s parents have been planning a trip, and her cousins, Titus and Timothy are coming, too. At the request of an old family friend, Ned, they are going to visit him and take a look at an old lighthouse that he is thinking of buying. He wants to turn the lighthouse into a bed and breakfast.

However, strange things have started happening at the lighthouse. Someone has vandalized the outside, and Sarah-Jane sees a frightening face up in the tower. Could the old lighthouse be haunted?

The theme of the story is faithfulness.

The book is available to borrow and read for free online through Internet Archive.

My Reaction and Themes

Since this is a Christian-themed mystery, readers can guess that there won’t be any real ghosts. This is more of a light, pseudo-ghost story, like Scooby-Doo mysteries, with another explanation for what’s happening.

There’s more than one kind of haunting. People can be haunted by memories, and living humans are also attached to the places associated with their happy memories. There is someone who has an attachment to the lighthouse and is unhappy that it’s being sold. This person needs to reconcile their feelings to the situation.

Some Christians don’t like the concept of ghost stories at all. In the book, Sarah-Jane likes hearing ghost stories, although she admits that she doesn’t like remembering them later, when she’s alone at night. She enjoys a little spooky excitement, as long as she knows it’s just a story, and she’s hearing it in a safe setting.

Look Up!

Look Up! by Robert Burleigh, illustrated by Raul Colon, 2013.

This picture book is about the life of Henrietta Leavitt, a “Pioneering Woman Astronomer” during the late 19th century and early 20th century.

The story says that Henrietta had a fascination with the night sky from a young age, often wondering just how high the sky was. When she got older, she formally studied astronomy, although most of the other students were men, and it was an uncommon profession for women.

After she graduated, she found a job with an observatory, although she rarely worked on the telescope. She was part of a team of other women who acted as human “computers”, doing basic calculations by hand and compiling information for others to use. Women like Henrietta were not expected to use this information themselves or draw conclusions from their own calculations, but Henrietta had her natural sense of curiosity and confidence in her ability to use her own mind.

She continued studying in her spare time, and while examining photographs of stars and doing her calculations, she began to notice some patterns that made her wonder about the explanations behind them. She studied an effect where stars seemed to become brighter and then dimmer, a kind of “blinking” effect.

She not only discovered that the existence of some of these stars had not been recorded yet, but she also found herself wondering about the pattern of this twinkling effect. Some stars appeared brighter and seemed to “blink” more slowly between bright and dim than other stars that weren’t as bright. By examining the relative brightness of the stars and the patterns of blink rate, she realized that it was possible to calculate the true brightness of the stars and use that to figure out how far away each star is from Earth. When she presented her findings to the head astronomer at the observatory, he was impressed. By using the chart Henrietta compiled, it was possible to calculate the distances of stars even beyond our galaxy. People of Henrietta’s time initially thought our galaxy might be the entire universe, but Henrietta’s finding shows that it was not and also that our galaxy is much larger than people thought.

The book ends with sections of historical information about Henrietta Leavitt and her discoveries and other female astronomers. There is also a glossary, some quotes about stars, and a list of websites for readers to visit.

My Reaction

I enjoy books about historical figures, especially lesser-known ones, and overall, I liked this picture book. The pictures are soft and lovely.

The only criticisms I have are that the book is a little slow and repetitious in places, and the subject matter is a little complex for a young audience. Some repetition is expected in picture books for young children, but how appealing that can be depends on what is being repeated. Henrietta’s work involves a lot of looking at pictures and figures and studying, so the text gives the feeling of long hours studying and “looking,” and many of the pictures are of her looking at books and examining photographs of stars through a magnifying lens. I found the story and pictures charming and in keeping with the Academic aesthetics, but I’m just not sure how much it would appeal to young children.

The story explains some of the concepts that Henrietta Leavitt developed and discovered, and it does so in fairly simple language. However, I still have the feeling that it would mean a little more to a little older child, who already knows something about astronomy, or to an adult like myself, who just enjoys the charming format of the story.

Part of me thinks that this story could have been made into a little longer book, perhaps a beginning chapter book, which would have allowed for a little more complexity. One of the issues with making the story of Henrietta Leavitt into a longer book is that, as the section of historical information says, “not a great deal is known about her life.” There just might not be enough known details about Henrietta’s life to put together a longer book.

Still, I really did enjoy the book, and I liked the presentation of 19th century astronomers and astronomical concepts. I especially enjoyed the way the story portrayed the concept of “human computers.” This type of profession no longer exists because we have electronic computers and computer programs that perform mathematical calculations faster than human beings can, but before that technology existed, humans had to do it themselves. “Human computers” had to work in groups to get through massive amounts of data and calculations, and it was long and tedious work, but their work was largely hidden from the public eye. As the story says, they were expected to do mathematical calculations and compile data, but they were compiling it for someone else’s use. Someone else would use their data to draw conclusions, and that person usually got the credit for whatever they discovered, ignoring all the people who did the grunt work that made it possible. Since women like Henrietta were more likely to be among the “human computers”, working in the background, they often didn’t get much credit for their work. The male astronomers were more likely to be the ones analyzing data and taking credit for the conclusions they drew, although they didn’t do the background calculations themselves. What made Henrietta different was that she stepped beyond the role of simply compiling information but also took on the role of studying patterns and drawing conclusions from the data she was compiling. She did all of it, from compiling data and making calculations to interpreting the data and laying out conclusions and discoveries from it.

Women once worked in similar positions as “human computers” at NASA. The 2016 movie Hidden Figures was about women working as “human computers” at NASA in the 1960s.

Maria’s Comet

Maria’s Comet by Deborah Hopkinson, illustrated by Deborah Lanino, 1999.

This picture book is a fictional story about a real person, Maria Mitchell. (She pronounced her first name “ma-RYE-ah”, not “ma-REE-ah”.) Maria Mitchell was born into a Quaker family on Nantucket Island, Massachusetts in 1818, and she became the first female astronomer in the United States. She is known for discovering a comet only viewable through a telescope in 1847, and she also became the first astronomy professor at Vassar College. She is the namesake of the Maria Mitchell Association, a science center on Nantucket. She was also an abolitionist, although this topic is not touched on in the book. Maria’s father taught her about astronomy when she was young and encouraged her interests and career at a time when not many women were encouraged to pursue careers or higher education.

Maria’s papa is an astronomer. At night, he goes up on the roof their house to use his telescope, and he explains how the telescope works, gathering and focusing light to make distant objects look larger and closer than they would with just a person’s eyes. He especially likes to look for comets. In their time, they’re not entirely sure what comets are made of, and that’s part of what makes studying them interesting. Maria imagines what it would be like to travel across the sky with a comet, encountering the different planets.

Most of Maria’s life centers around their house and family in Nantucket. There are nine children in the family, so Maria helps with chores and tells her siblings bedtime stories. Sometimes, she and her brother Andrew go into the attic and use an old atlas to pretend that they’re explorers. When they read books, Maria likes books about astronomers, but Andrew likes books about sailors. He wants to be a sailor himself.

When Andrew gets older, he runs away from his family to go to sea on a whaling boat. The entire family is sad that he is gone, and Maria soothes her siblings by telling them stories about all of the amazing places their brother will go. That night, after supper, Maria asks her father if she can come with him to look through his telescope or “sweep the sky” as she thinks of it. For a moment, Maria thinks they will say no, but they agree. Maria wants to be an explorer of the sky, like her brother wanted to explore the seas.

Maria’s father points out Polaris, the North Star, to Maria and says that sailors use it to navigate. Maria wonders if Andrew might be looking at the same star right now. Then, she sees a comet streak across the sky.

There’s an Author’s Note in the back of the book that explains about the real life of Maria Mitchell. It has some comments about what people of her time knew and didn’t now about the planets. When she was young, people only knew about seven planets in the solar system. Neptune was discovered during her lifetime (although not by her), and Pluto wasn’t discovered until 1930, after she had died. There is also a section about the astronomy terms used in the story and famous astronomers.

My Reaction

I enjoy books about historical people, although the author admits in the Author’s Note that this particular story about Maria Mitchell is fiction. I have mixed feelings about that. I don’t like to fictionalize real people, and I’m not entirely sure whether there’s any truth to the story about Maria’s relationship with her brother and how she felt when he left to become a sailor. On the other hand, I did appreciate how the book showed Maria becoming interested in astronomy by watching her father and joining him in his studies of the sky, which is apparently true. Overall, I did enjoy the story.

The pictures in the book are wonderful. They capture the coziness of an old-fashioned 19th-century home and also the wonderment of looking to the skies and imagining exploring the big, wide world and the stars beyond it.

Five Secrets in a Box

Five Secrets in a Box by Catherine Brighton, 1987.

This story is about Virginia Galilei (1600-1634), the eldest child of Galileo Galilei, and her perception of his work and equipment as a young child. The book has sections of historical information about Galileo and Virginia in the front and the back inside cover, although the story itself is just about Virginia exploring Galileo’s study.

Virginia, as a young child, knows that her father stays up late at night, studying the night sky, while she is asleep. During the day, she must be quiet to let him sleep. She is not really supposed to touch his scientific instruments, but she can’t resist the temptation to take a look. In her father’s study, she finds a box with five mysterious objects in it, and she investigates what they do.

One of them is a lens that makes small things look bigger. Another is a lens that makes things that are far away look closer. There is another lens that makes everything look blue and another that makes everything look red. Then, there is also a plain, white feather.

Virginia wonders what the purpose of the feather is, and she asks her father about it. He tells her that it is important to his work.

The book is available to borrow and read for free online through Internet Archive.

My Reaction

According to the historical information provided, little Virginia’s mother left Galileo and married someone else while Virginia was still young. Virginia remained living with Galileo and was close to her father. When she was 12 years old, her father sent her to a convent, which was a fairly common way for upper-class girls at that time to get an education. However, Galileo probably intended for his daughters to join the Church as nuns rather than marrying when their education was complete. The book doesn’t explain this, but Virginia and her younger brother and sister were born out of wedlock. Because they were illegitimate (born outside of a legally-recognized marriage – the word “illegitimate” literally refers to someone born outside of the law and legal standing with implications about both the legal status of their parents’ union and the child’s possible future inheritance, depending on the laws of that particular society), their social status was compromised from birth. Galileo believed that it would be difficult for his daughters to find husbands, so joining a convent and becoming nuns would provide the girls with stable lives and careers as well as an education, which is what both of them did. Virginia remained at the convent as a nun, taking the name of Sister Maria Celeste, and unfortunately, died relatively young at the age of 34. The book doesn’t say why, but it was because she contracted dysentery, which is caused by consuming tainted water or food.

The story itself doesn’t really explain the purpose of the five special objects that Virginia examines in her father’s study. Some of them are obvious because readers will recognize what they are and the way they work. The purpose of the feather is left a little mysterious at the end, but readers get the full explanation by reading the section of historical information. Galileo was studying gravity, and apparently, he dropped objects off of the leading tower of Pisa to study how long it took them to fall. A feather will take longer to reach the ground than a stone, but that’s because of air resistance. One of Galileo’s premises was that, if there were no air to produce that air resistance, the stone and the feather would fall at the same rate of time due to gravity. I think I would have preferred to have Galileo explain some of this to his daughter when she asks him about the feather, but the story ends kind of abruptly at that point, with Virginia just playing with the feather. I felt like the ending isn’t exactly an ending without that explanation.

The pictures are the main reason why I really liked this book. They are colorful and realistic, and I thought they did a great job of showing the scientific instruments of the past. I also liked some of the little details of the house included in the backgrounds of the pictures. There is a crucifix hanging on the wall behind the telescope in Galileo’s study because this is a religious household, even though some of Galileo’s assertions about the way the world works clashed with Church teachings and got him placed under house arrest. (The book says that he was “sent to prison”, but he was actually placed under house arrest rather than being sent to a prison because he was elderly and in bad health by that point in his life.)

The book doesn’t go into detail about Galileo’s arrest because that happened later in his life, but he was basically considered a heretic for his belief in Copernicus‘s theory that the sun is the center of the solar system instead of the Earth. That sounds like a rather petty charge, and you might wonder why it matters or what different it could make to religion. It wasn’t a new idea because others had reached that conclusion long before him. Copernicus was never arrested for his ideas, partly because he didn’t live very long after he published them, but his book was placed on the restricted list by the Inquisition.

The reason why the relative positions of the sun and the Earth mattered depend on whether particular Biblical passages are meant to be interpreted literally or figuratively. Under a strict literal interpretation, which was the interpretation approved by the Church at that time, the conclusion was that the Earth was the center of the solar system, so saying otherwise would be to go against the Bible and Church teaching, making it a heresy. It wasn’t so much that the relative positions of the sun and the Earth were that important by themselves so much as the act of apparently contradicting the Bible. The Renaissance era was also the era of the Reformation, where Protestants were breaking away from the Catholic Church, partly because of the questions of literal interpretation of the Bible and Church doctrine. The Catholic Church’s response to that during this period was to become more strict in enforcing moral and doctrinal standards in the Counter-Reformation, so anything that seemed to challenge these aspects of the faith was taken far more seriously during this period. This stance would shift again later in history.

The background and aftermath to this story is far more complex than the story itself, although I think part of the charm of the story is it’s simplicity. This is one particular day and a small incident, seen through the eyes of a child, even though adult readers know that there are bigger events surrounding it.

Anno’s Journey

Anno’s Journey by Mitsumasa Anno, 1977.

This picture book is unusual because there are no words in it at all until the very end. It’s all pictures, except for the part that explains the inspiration for the story. The author/illustrator, Mitsumasa Anno, depicts himself as a traveler, traveling through the countryside and towns of Europe. The “story” is the story of his journey, but it’s all in the pictures.

In the first pages of the book, we see Anno arriving by rowboat and either buying or renting a horse. The following pages are a little like the Where’s Waldo/Wally books, showing Anno’s travels. Anno appears somewhere on every page, riding his horse, but readers have to look for him. There are also other things to look for, but readers don’t get that explanation until the very end.

The scenes start out in the countryside, and as Anno goes through towns and cities, they can be very busy, with many people and lots of things happening. Toward the end of the book, Anno goes through the countryside again, and it ends with him riding off toward the horizon.

Along the way, there are interesting, detailed scenes that show various aspects of countryside and town life. There are people working in farm fields, people packing up to move house, some men carving tombstones for a churchyard, some children playing and running a race near their school, and a busy market square.

There are also special occasions and very busy scenes, from a wedding in front of a town church to a circus scene and a parade through a city. Aside from the main event in each scene, there are also other things happening in the background, from people working to repair a roof to a prisoner escaping from a castle. Through it all, Anno is always somewhere in the scene, riding the horse.

There is hidden depth to the pictures. There is a section at the back which explains the story behind the book. The author and illustrator, Mitsumasa Anno, is from Japan, but he has always been fascinated by European culture, art, and architecture. Twice, during the 1960s and 1970s, he visited Europe, taking in the sights and producing his own art. This book is based on his travels, and the pictures incorporate the types of towns, fields, and churches he saw. However, they also include many hidden details, including details from famous paintings, characters from books and folktales (and also Sesame Street), and the stories of some of the characters in this book, carried across multiple pages, for readers to notice.

The book is available to borrow and read for free online through Internet Archive, along with a couple of other books by the same author, in a similar format, Anno’s Italy and Anno’s Britain.

My Reaction

I enjoy books with detailed pictures, especially ones that contain details for readers to notice, like a game. I didn’t see many of the details that are hidden in plain sight until after I read the explanation of what to look for, but there is quite a lot to see in this book. It’s the kind of book that you can look at many times and notice something new every time! Although this is considered a children’s picture book, I think that there are many things that adults might see in it that would go over the heads of children. Children wouldn’t be likely to get all of the art references, for example. It’s a book that can appeal to a variety of people of different ages!

Moonflute

Moonflute by Audrey Wood, illustrated by Don Wood, 1980, 1986.

One night, a little girl named Firen can’t sleep. It’s a hot summer night, the moon is full, and Firen feels like the moon has taken away her sleep, so she must go out into the night and look for it.

Outside, Firen raises up her hands to the moon and asks for her sleep back. The magical moon sends her a moonbeam, and when Firen touches it, she realizes that it’s solid. It’s actually a flute. When Firen plays the flute, it makes magical music that doesn’t sound like any normal flute, and it brings all sorts of wonderful smells of things that Firen loves. As she continues to play, she feels light and tingly, and she realizes that she is rising into the air!

Firen flies over the countryside, looking for her sleep. As she journeys through the night, she sees various animals and wonders if they have her sleep. She sees cats in a patch of catnip, whales playing in the ocean, and bats and monkeys in a jungle.

When Firen sees a couple of monkeys soothing a baby monkey to sleep, she thinks about her own parents and uses the flute to return home. Is the moonflute helping her find her sleep at home with her parents, or has she actually been asleep all the time?

The book is available to borrow and read for free online through Internet Archive.

My Reaction

This book follows the “It was all a dream” theme, where the main character experiences something fantastic, but they were dreaming all the time. While Firen was wondering where her sleep was, she apparently fell asleep. It isn’t definite that’s what happened, but it’s implied when her parents go to her room, and she’s in bed, without the flute. If readers would like to think of it differently, that Firen really did have her flying adventures, it’s possible to read it that way, too.

The pictures really make this book! The illustrations are oil paintings, and they are beautiful and ethereal. Firen witnesses some stunning scenes, like whales leaping in the ocean, with everything bathed in glowing moonlight.

I was intrigued by the name “Firen” because I don’t think I’ve heard it before, and I like unusual names. I couldn’t find much information about the name online, so it seems like it isn’t very common. I thought at first that it might be a modern, invented name, although one name site says that it has Arabic origins.
