The concrete of ancient Rome is famous for its durability. Just look at the Pantheon and those iconic aqueducts that helped transport water throughout the empire—still standing 2,000 years later.

But knowledge about how this concrete was made hasn’t been very solid. Well, scientists have discovered a construction site in Pompeii preserved in the volcanic ash, which might hold clues to how we can improve our concrete today. Concrete researcher Admir Masic joins Host Ira Flatow to discuss the findings.

Plus, we’ll look at the infrastructure of the future with engineer Benjamin Lee, who breaks down the recent news of tech companies looking to move their power-hungry data centers to space. They discuss the daunting engineering challenges and possible benefits.

Guests:
Dr. Admir Masic is an associate professor of civil and environmental engineering at MIT in Cambridge, Massachusetts.
Dr. Benjamin Lee is a professor in the department of electrical and systems engineering and the department of computer and information science at the University of Pennsylvania in Philadelphia.
