Chad Johnson joins Matt Smith and Brian Cross to go tripping through the doors of perception. The team takes on the therapeutic use of psychedelics and the sometimes tricky line between psychedelic scientist and spiritual guru. Matt gets in touch with his alchemical roots as he dephlogisticates the element oxygen. In the headlines, Moas rear their lofty heads, the Parker Solar Probe catches the solar wind, and scientists attempt to fix the “Matthew Effect.”
