Takamitsu “Taka” Ito - Turning Sour, Bloated, and Out of Breath: Ocean Chemistry under Global Warming

In 1997, the Japanese oceanographer Yoshiyuki Nozaki compiled a periodic table of ocean chemistry, encapsulating the distribution of elements as a function of depth. In this periodic table, many…

Computer Science in Six-Tenths of a Second: What Happens After Hitting ENTER in a Google Search - Lance Fortnow

What is computer science? Ask Google or Alexa, and you'll get an answer like "the study of the principles and use of computers." That doesn't really capture the breadth of the…

Ordered and disordered motion in dense active materials - Ludovic Berthier

We discuss how the non-equilibrium driving forces introduced by the natural biological activity or by physical self-propulsion mechanisms generically affect the structure, dynamics and phase behavior…

Local and global avalanches in sheared granular materials - Aghil Abed Zadeh

We perform a stick-slip experiment to characterize avalanches for granular materials. In our experiment, a constant speed stage pulls a slider which rests on a vertical bed of circular photoelastic…

Exploiting disorder - Sid Nagel

We are taught to understand solids by considering ideal crystals. This approach becomes untenable as the amount of disorder increases; for a glass with no well-defined long-range order, a crystal is…

The Topological Character of Smectics - Randy Kamien

Though the systematic use of topology to understand defects in ordered matter is now nearly 50 years old, the original work failed to completely characterize systems with broken translational order,…

Fracturing of marginally stable structures: fiber networks and topological metamaterials - Xiaoming Mao

When conventional brittle materials break, long cracks form due to stress focusing at crack tips: a phenomenon explained by Griffith in the 1920s. In this talk, we will discuss two types of systems…
