The term 'confinement' is used in the podcast episodes to describe different types of constraints or limitations, both physical and conceptual.

In the first episode, WikiPlea: Assange to Go Free, the context of confinement refers to Julian Assange's years of confinement, first in the Ecuadorian embassy and then in UK custody, which is cited as a factor in his accepting a plea deal to avoid a US prison sentence.

In the second episode, 275 | Solo: Quantum Fields, Particles, Forces, and Symmetries, the concept of confinement is discussed in the context of quantum chromodynamics (QCD) and its role in explaining the short-range nature of the strong force.
