Performance art differs from other performances, like dance and theater

While performance art is a very flexible genre, it is defined by several core elements: time, space, the body, and the relationship between the artist and the audience. These elements may be manipulated in infinite ways to convey the artist’s message, such as how endurance performances challenge the limits of the body over long periods of time.

The 1819 novel 'Ivanhoe' popularized the word 'freelancing'

In the novel, the author wrote about “free-lances:” mercenary soldiers who were “free” to use their weapons (called, yes, “lances”) in service of whoever paid them the most. A video details that story and other gig economy basics.

Graffiti has its own visual language, including simple 'tags,' large block letters, and complex 'pieces'

Every graffiti artist looks to create their own visual identity, but they often rely on common folk styles, especially when they're still developing their craft. "Tags" are little more than an artist's pseudonym, while "Wildstyle" takes an abstract approach to the signature. More complicated styles, like "blockbuster," are like informal billboards strapped to the sides of buildings and subway cars.

What is rhetoric?

The roots of "rhetoric" stretch back to ancient Greece, where early philosophers defined rhetoric as the art of winning the soul through discourse or the art of persuasion.

‘SNL’ sketches often follow a uniform structure

Sketch comedy relies on pacing, with scripts that hit certain beats. "SNL" often greenlights sketches that lean into a particular formula that features two "turns," or unexpected events that disrupt the "base reality" of the story.

Laminar flow moves in smooth, parallel layers, while turbulent flow is chaotic

In laminar flow, particles that make up a fluid move in consistent paths that do not cross each other. Contrastingly, differences across the speed of these particles cause them to mix, creating turbulence when viscosity cannot suppress the differences.

Sartre believed those who deny their own freedom are operating in 'bad faith'

In "Existentialism is a Humanism," Sartre argues that humans are "condemned to be free"—they are not confined to a divine fate, which means they must take the responsibility of creating their own destinies. Those who reject this freedom, by his estimation, are living in "bad faith."

Despite claims of limitless free energy, zero-point energy cannot be harnessed

Because quantum mechanics prevents systems from ever reaching an energy value of zero, a seemingly empty vacuum of space still contains some amount of energy associated with its lowest allowed state. Since descending to even lower states is forbidden, extracting meaningful amounts of energy from an empty vacuum is impossible.

Pure water does not conduct electricity because this flow of energy requires the movement of charged particles, and water is a neutral molecule.
