This chapter explores the various tools used to gather information from the body, including passive instruments that detect warmth and use x-rays, as well as active instruments that send pulses or radiation through the body. The hosts also discuss the potential of using these tools for diagnosing medical conditions.
Is our experience of time a result of our perpetual movement? Neil deGrasse Tyson and co-hosts Chuck Nice and Gary O’Reilly explore spacetime, metaphysics, the Brachistochrone problem and more with astrophysicist Charles Liu.
