STEM Tuesday– Bridges and Skyscrapers– Author Interview

Today, we are thrilled to travel to the Czech Republic to interview Magda Garguláková, author of Bridges (April 2025, Post Wave). Explore the amazing world of bridges—from ancient stone arches to modern marvels—and discover how they connect us all! This illustrated 64-page hardcover book delves into the history, engineering, and construction of bridges. Intricate illustrations by Jakub Bachorík invite readers to follow roads and rivers and stumble upon tiny details: a cyclist, a stroller, a leashed dog, and more. 

About the book:

Imagine a world without bridges, where every journey takes longer, rivers become obstacles, and valleys are nearly impossible to cross. Bridges don’t just make travel easier—they connect us to extraordinary places, too.

Take a journey through the fascinating world of bridges, exploring their awe-inspiring structures and the visionary architects who brought them to life. Uncover the secrets of bridge-building and marvel at some of the most famous designs from around the globe. Along the way, enjoy captivating comic strips, fun facts, and hands-on engineering activities.

Bridges

Linda: Tell us about your book, Bridges.

Magda: Bridges is a large-format, illustrated non-fiction book that invites readers into the world of bridges. It is richly illustrated with Jakub Bachorík’s distinctive, playful, and original—yet highly precise—artwork.

I like topics that can be explored from many different angles, and bridges are perfect in this respect. In the book, I don’t look at them strictly as architectural structures, engineering constructions, or from the perspective of how they are built. I also ask why people started building bridges in the first place, how they influenced history and technological progress, how they have evolved, how they have changed our everyday lives, why they are such powerful symbols, and what surprising kinds of “bridges” we can find outside architecture.

The book is intended primarily for children aged nine to eleven. It is fact-based but playful, and the amount of text is just right. I tried to draw readers into the topic and spark curiosity about bridges. Although it is designed for children, it also works very well as an all-age book. I’m really happy with readers’ responses, as it turns out that it resonates across generations and appeals to adults as well.

Linda: That’s wonderful. What inspired you to write about this topic?

Magda: It’s actually quite simple. I’ve been fascinated by bridges since childhood. I don’t even really know why, but they’ve always drawn me in and sparked my curiosity. I’m also an amateur admirer of architecture, especially modern architecture, and I love concrete as a building material as well as riveted steel structures.

What fascinates me about bridges is not only their technical side; I’m equally drawn to how multilayered a symbol they are—how they can bring hope and expectation, how important a role they play in our lives, and, at the same time, how ordinary and invisible they often feel in everyday life. I enjoy the overlaps they offer—into history, art, culture, and everyday experience.

And then there’s one more thing: I’m afraid of heights. So bridges are also a bit of a challenge for me. I actually prefer looking at them rather than from them—and quite often, that turns out to be a more interesting view anyway. 😊

All of this together makes them a perfect subject for a book. It also invites rich illustration, which can communicate with readers in its own way, which is why I like to give illustrations a very important role in my books.

Linda: The textured maze-like illustrations complement the text. How did you organize the material in this book, and why did you choose to present it this way?

Magda: Let me start a bit broadly. When I begin working on a book, the first thing I look for is its overall arc: where I start and where I want to arrive. The flow of the book—how individual pieces of information and thematic sections are arranged—is essential to me. I constantly think about what follows what, why it should be that way, and to what extent I need to follow the logic of the subject. These are questions I return to again and again. During the process, I create several versions of dummy layouts where I test and rearrange the order and structure of the content. It’s one of the most important parts of my creative process.

At the same time, I enjoy when the reader is occasionally surprised, and the expected flow is interrupted—when the rhythm of the book shifts or something unexpected appears.

Bridges reflects all of this. It follows a logical structure of the topic, but it also allows for occasional detours. I wanted the book to flow like a river—one idea leading to another, layering and complementing each other.

It was also important to me that the book works even when read non-linearly. In other words, you can open it almost anywhere and immediately find something that grabs your attention. In this respect, Jakub Bachorík’s illustrations are essential—I knew from the very beginning that they would not just accompany the text, but become an equal part of the storytelling. Thanks to them, the book gains its unique atmosphere and appeal.

Linda: In the book blurb, there is a statement that “bridges connect us to extraordinary places.” Can you tell us about some of these places?

Magda: When I say that bridges connect us to extraordinary places, I don’t mean only specific destinations on a map or in our surroundings, but also different kinds of experiences and meanings. Some bridges lead into dramatic natural landscapes, places that would otherwise be very difficult to reach. Other bridges become destinations in themselves—iconic landmarks and architectural highlights that people travel to see.

At the same time, we also use the word “bridge” in much broader contexts. Metaphorically, a bridge can take us anywhere we can imagine. We perceive it very positively as a symbol of change or transition, and it can even signify passage into another world. It is a very powerful symbol on many levels.

And then, there is also a more playful aspect where we encounter “bridges” in unexpected places—such as in dentistry or in a yoga class.

Linda: By looking at the word “bridge,” and its many meanings and its symbolism, you added depth to this work. What would you like readers to get out of this book?

Magda: I often think about this. If I keep it to the most basic wish, it is simply that I want my book to inspire enthusiasm for bridges, encouraging us to notice, explore, and appreciate them.

If a reader, thanks to my book, decides to stop on a bridge and enjoy the view, remembers the complexity involved in bridge construction, or, with joy and an awareness of their importance, appreciates a bridge expansion joint, that would already be enough.

The book is quite intense, so it is good to take breaks while reading it, come back to it, and discover things that may have escaped you the first time. I would therefore be very happy if the book worked this way and readers enjoyed returning to it—either on their own or when reading it together.

I have also personally found that it is a great travel companion; it presents a large number of bridges from all over the world, many of which you will simply want to see in real life (or at least some of them). 

Linda: This book includes fun engineering activities. I’m intrigued. How can parents, teachers, and librarians use this material?

Magda: The book includes a challenge to build your own bridge out of dried spaghetti. It’s a playful activity, but it also works as a small test of engineering thinking and technical skills. The task is to build a bridge—of any size and design you dare to attempt—that can hold a load without collapsing.

This activity can be used at home, in schools, or in libraries as a simple project or even a small competition. It is a lot of fun, but also requires real thinking. I’ve tried building several of these bridges myself—and you can probably guess how that went…

Linda: Lol! Instead of building a bridge, it might be easier to boil the spaghetti and toss it with some pasta sauce. Magda, thank you so much for joining us!

STEM Tuesday– Architecture– Interview with Nancy Castaldo!

Welcome to STEM Tuesday: Author Interview, a repeating feature for the last Tuesday of every month. Go Science-Tech-Engineering-Math!

Today, I’m delighted to interview a founding member of STEM Tuesday, Nancy Castaldo!

Nancy’s most recent book is an exploration of a very cool topic – green buildings! And not painted green. No, these buildings are growing, thriving, and . . .  breathing!

BUILDINGS THAT BREATHE: GREENING THE WORLD’S CITIES takes young readers on a journey around the world to discover ecological, sustainable architecture practices such as incorporating trees and other forms of native vegetation into buildings.

Why design buildings that breathe? Because it’s healthier – for humans, wildlife, and the planet. And, these buildings are beautiful!

Learn more about Nancy’s research and writing process:

cover Buildings That Breathe

Andi Diehn: What a great title – what sparked the idea for this book?

Nancy Castaldo: As an Italian-American, I have Italian news stories on my radar. I was excited when I came across the story of Bosco Verticale in Milan. In addition, I studied architecture in graduate school after all my earlier science studies. This project dovetailed with both of those interests. I wasn’t sure what direction the book would take until I attended the United Nations Forum in Urban Forestry in Mantua, Italy in 2018. The book formed out of that participation. I had the opportunity to meet with so many global leaders in urban greening.

AD: Boeri refers to a “new Renaissance” when talking about the future of cities. What does he mean by this?

NC: The Italian Renaissance was a period of recovery from disasters that occurred in the 14th century and a period of tremendous innovation. Milan was home to Leonardo da Vinci, a Renaissance master of innovation. Boeri, the architect for Bosco Verticale, is calling for the opportunity for tremendous innovation in the world’s cities today. His design and his collaborations in Milan and elsewhere are at the forefront of that innovation.

AD: The story of Seneca Village was fascinating – why is it important to remember the people who lived there before the land became Central Park?

NC: Seneca Village and the dissolution of it is important to everyone everywhere. It is an historical example of social injustice that went on and that still occurs in gentrification projects. The residents of Seneca Village that were displaced had their lives disrupted just as many still do today.

green skyscraperAD: Boeri’s vision of a building that incorporates trees and essentially becomes one great tree that “incidentally houses humans” is a real shift from our traditional way of thinking of architecture as serving humans—these buildings serve the land. Why do you think that shift is happening now?

NC: Cities need to be made more livable for residents and healthier for our planet. Urban greening projects do both. The shift is important to combat human-caused climate change that damages our planet and individual health. Cities produce three-quarters of carbon dioxide emissions along with many other pollutants. As city populations increase, so do those emissions. We can do better. Urban greening is one big tool in our toolbox.

AD: You write about Boeri’s team members and their backgrounds, including Laura Gatti and Emanuela Borio. Is it important to have many voices contributing to the plans? Why?page from Buildings That Breathe

NC: Everyone has their own specialties in creating such extraordinary, innovative designs. All contribute to the project’s success. I’m hoping that young readers, of all genders, will find inspiration from these individuals in STEM careers.

AD: I had no idea that growing trees and bushes on buildings was so complicated! What are some of the things the designers have to consider?

NC: The book describes how the team had to deal with issues of wind and weight on the structure and its trees. When groundbreaking projects like Bosco Verticale are constructed, lessons can be learned for all buildings going forward.

AD: In March, the Intergovernmental Panel on Climate Change announced that we’d be crossing a critical global warming threshold in the 2030s if we didn’t make major changes—how do books like yours help younger generations understand the climate situation?

NC: I hope that Buildings That Breathe can not only inform my readers but inspire them to think about other creative solutions to our global climate crisis. I’ve included ways readers can also get involved in their own communities throughout the book and in the backmatter.

AD: I love the idea of making our living spaces more welcoming to wildlife and birds. How do we balance the benefits of living near and among animals with the possible risks?

NC: Coming to the realization that humans and wildlife are all sharing the same spaces on the planet is the first step. Respecting those creatures that inhabit our world comes next. Learning how to live with wildlife can be a fulfilling and a healthy way to enhance our lives. Do your homework. Think of things like adding bird feeders and native plants to yards and terraces.

AD: I like how you discuss modern innovations alongside ancient technology like sod roofs. What can we learn from looking at old ways of doing things?

page from Buildings that Breathe

NC: If it isn’t broke, don’t fix it. That old adage is often true. A look back at traditional solutions might inspire how we develop new ideas, like green roofs.

AD: I love the story about people celebrating rooftop gardens and posting their pictures to social media. Why is this kind of connection an important part of combatting climate change?

NC: Good news should be spread, don’t you think? It’s one of the best uses of social media. Let’s hope it will inspire action and change.

AD: You include a discussion of pros and cons in most chapters – why is it important to look at innovations from all different sides?

NC: All voices need to be heard. In that way, solutions can be addressed. Everyone’s voice matters. And we all know that “there is no free lunch.” Solutions are not always 100% risk free. We should acknowledge that and attempt to make the best decisions going forward to mitigate any problems.page from Buildings That Breathe

AD: I like that you discuss green architecture happening in lower-income areas, and the problem of eco-gentrification. How are innovators addressing the need to reach all populations, not just the wealthy? How might they work with existing neighbors to ensure no one is forced out of their home for the sake of green building?

NC: This is a huge topic, but one that needs to be addressed. I included it because all stakeholders in urban projects need to be considered. Sadly, not all city neighborhoods have the same amount of parks and greenery. More parks are needed to even this out and create healthy places for all city residents. In addition, residents who suffer from eco-gentrification projects need to have their voices heard and their properties considered. Suggestions for how readers can attend public forums and ways to turn your community green are included in Buildings That Breathe.
