How we use astrophysics to study earthbound problems | Federica Bianco

TL;DR

This content explores how an astrophysicist turned her restlessness into an asset by applying her expertise to urban observatories and analyzing various data sets to create transformational solutions.

Transcript

I am an astrophysicist. I research stellar explosions across the universe. But I have a flaw: I'm restless, and I get bored easily. And although as an astrophysicist, I have the incredible opportunity to study the entire universe, the thought of doing only that, always that, makes me feel caged and limited. What if my issues with keeping attention ... Read More

Key Insights

• 🌌 Astrophysicists study stellar explosions in the universe but can feel limited by the inability to interact with their subject matter.
• 🌌 Studying images of the sky has allowed astrophysicists to learn about various aspects of the universe, from the big bang to the evolution of stars and galaxies.
• 🌃 The Urban Observatory, created by astrophysicist Greg Dobler and his wife in 2013, applies astrophysics expertise to studying city lights and pollution.
• 🌃 By studying city lights like stars, insights can be gained about the nature of exploding stars, as well as predicting and managing energy consumption in urban environments.
• 📸 A mathematical model, using image analysis techniques from astrophysics, was built to track plumes of pollution in New York City, providing valuable information for policymakers.
• 🔬 The data analysis methodologies used in astrophysics can be applied to various kinds of data, not just images, as demonstrated when helping a California district attorney understand prosecutorial delays.
• ⚖️ By leveraging astrophysics methods, biases in the prosecution process were identified, leading to transformational solutions that can be applied in other jurisdictions.
• 💡 Exploring outside one's domain, like adapting models used to detect pollution to detect light echoes in the sky, can turn restlessness into an asset and lead to unexpected insights and solutions.

Questions & Answers

Q: What is the purpose of the Urban Observatory?

The Urban Observatory's purpose is to turn the camera towards the city and apply astrophysics expertise to study urban environments. They take pictures of the city at night and analyze city lights like stars to gain insight about the nature of exploding stars. They also capture daytime images to study pollution plumes and build mathematical models to track and classify them, providing policymakers with important information about neighborhood pollution.

Q: How does the Urban Observatory apply data analysis methodologies used in astrophysics to other types of data?

The Urban Observatory applies data analysis methodologies used in astrophysics to various types of data, not just images. For example, they assisted a California district attorney in understanding prosecutorial delays in their jurisdiction. They created visual dashboards to help the DAs better understand the prosecution process and analyzed their extensive data to determine if social inequalities impacted the duration of the process. By using methods typically used to classify stellar explosions, they built a model that can be applied to other jurisdictions to explore biases.

Q: How does the astrophysicist's restlessness and tendency to get bored become an asset?

The astrophysicist's restlessness and tendency to get bored become an asset by driving her to explore new areas outside of her domain. By reaching outside of her expertise and embracing her restlessness, she was able to bring new perspectives and insight to urban science. This led to unexpected collaborations and transformational solutions that improved people's quality of life.

Q: How is the knowledge gained from urban science applied back to the field of astrophysics?

The knowledge gained from urban science is applied back to the field of astrophysics by adapting and applying the same models and methodologies to images of the sky. For example, the Urban Observatory is using the models that detect pollution plumes in city images to detect light echoes in images of the sky. This cross-pollination of ideas and techniques between urban science and astrophysics helps to generate new insights and unexpected solutions in both fields.

Summary & Key Takeaways

• The speaker, an astrophysicist, has a restlessness and boredom that she turns into an asset by studying city lights and pollution in urban environments.

• Using the same data analysis methodologies as astrophysics, the speaker and her team help a district attorney understand prosecutorial delays and explore social inequalities in their jurisdiction.

• The speaker applies her astrophysics background to urban science and vice versa, adapting models to detect light echoes in the sky, emphasizing the importance of exploring different interests to generate new insights and solutions.
