In this episode, we meet with Dr. Arnold Mathijssen, Assistant Professor of Physics at U. Penn., and author of a paper recently published in Physics of Fluids, "Pour-over coffee: Mixing by a water jet impinging on a granular bed with avalanche dynamics". This paper just did the mainstream media rounds, so you may have heard about its findings on some other outlet. In this podcast we break it down and figure out whether physicists at U. Penn. revolutionized pour over.

The paper can be found here and is also available in the CLR library (link on instagram, @coffeelitrev).

Introduction featuring James Hoffmann.

Chris is joined by Dr. Alex Murray to discuss chlorogenic acid. We talk about how plants make it, what it does, what it tastes like, and how we might make it. We discuss a variety of papers, book chapter, and so forth. Check the library link on instagram for some of them.

Then, we shift to discussing movies of 2024 with Prof. Carl Brozek. Did anything released this year compete with Prof. Brozek or Chris' top three movies of all time?

About Dr. Alex Murray: He is from Hull, UK, and received his PhD from Bath. After a brief postdoc at MIT, followed by a professorship at Kent, he joined a startup Boston-based startup, Daqus. They specialize in creating novel battery materials. Chris and Alex lived together during their PhDs. and have been doing annual awards for a long time, but its the first time we put it on record.

About Prof. Carl Brozek: Prof. Brozek leads a materials chemistry research group at the University of Oregon. He is from Chicago, with a PhD at MIT and postdoc at Washington. Chris and Carl collaborate a lot.

Introduction preamble: Airplane 2.

Chris and Doran are joined by Emilee Bryant to discuss a pair of papers that probe whether latte art a) is perceived as more valuable and b) affects the perceived flavor of the drink.

Ordering a cappuccino is delightful. But is it more delightful with a rosetta? Would you be somehow compelled to pay more for it if it had one? Does it taste sweeter?
