Rewriting Plasma Physics - Dr. Patrick Vanraes, DemystifySci #341

Patrick Vanraes is a postdoctoral researcher at the University of
Antwerp whose research into liquid plasmas has led him to believe
that we have radically, completely, totally misunderstood what it
means for something to be “plasma.” All presentations on the
subject begin with a rote recitation of the fact that plasma is a
fourth state of matter - solid, liquid, gas, then plasma. But
Patrick makes the point that this is an incomprehensible
perspective, because the phase change between solid - liquid -
gas is one of motion. Each phase has more degrees of freedom than
the previous one, and so reveals different macroscopic qualities
of the substance. The transition to plasma is far stranger. Some
component of it does include a greater range of motion, as the
electron shells of the atoms bloom away from their ionic cores.
But far more important is the structural, chemical changes that
accompany plasma, which is exactly what leads Patrick to the
conclusion that perhaps plasma isn’t some strange exotic kind of
matter - it’s some latent capacity of matter that’s far more

#longformpodcast ABOUS US: Anastasia completed her PhD studying
bioelectricity at Columbia University. When not talking to
brilliant people or making movies, she spends her time painting,
reading, and guiding backcountry excursions. Shilo also did his
PhD at Columbia studying the elastic properties of molecular
water. When he's not in the film studio, he's exploring sound in
music. They are both freelance professors at various
universities. PATREON: get episodes early + join our weekly
