Analyzing Tsunami Waves with an Established Benchmark Model
The 1993 Hokkaidō earthquake in Japan caused tsunami waves that reached massive runup heights — one recorded wave in Monai Valley even reached as high as 32 m (~104 ft)!
The Science Behind Cooking Caramel
Whether you’re adding it to brownies, crème brûlée, or an ice cream sundae, cooking caramel is a precarious task: One wrong move and it could burn and taste bitter or recrystallize and harden.
Modeling the Behavior of an Oldroyd-B Polymer
Have you ever noticed that when a certain force is applied to a viscoelastic fluid, the fluid starts to look like beads on a string? Here, we showcase an example that uses an Oldroyd-B polymer.
