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.
