Schrodinger's Cat Is In Town II

Schrodinger's Cat Is In Town II

In this workshop ideated by Postdoctoral Fellow Dena Izadi from the Physics Education Research Lab and Professor Mohammad Maghrebi, makers, physicists, and the community are invited to come together to explore physics phenomena through art. Work collaboratively with Abbie Stevens, NSF Astronomy & Astrophysics Postdoctoral Fellow, to create visual representations of pulsars—celestial objects that emit electromagnetic radiation!

  4. Neutron star • Leftover when a massive star (10-20x as

    big as our Sun) dies in a supernova • About 15 miles across, with 1.5x the mass of the Sun! Watts+16 Image credit: Google maps
  5. Neutron star • Leftover when a massive star (10-20x as

    big as our Sun) dies in a supernova • About 15 miles across, with 1.5x the mass of the Sun! • Their average density is equal to the density of an atomic nucleus! Watts+16 Image credit: Watts+16

  7. Neutron star • Leftover when a massive star (10-20x as

    big as our Sun) dies in a supernova • About 15 miles across, with 1.5x the mass of the Sun! • Their average density is equal to the density of an atomic nucleus! • VERY strong gravity: acceleration at surface is 100,000,000,000x stronger than on Earth Watts+16 Image credit: JBO/John Rowe Animation

    star (10-20x as big as our Sun) dies in a supernova • About 15 miles across, with 1.5x the mass of the Sun! • Their average density is equal to the density of an atomic nucleus! • VERY strong gravity: accelera_on at surface is 100,000,000,000x stronger than on Earth • Has a magne_c field 1 billion – 1 quadrillion _mes stronger than Earth’s

  10. PULSAR • A neutron star with a very strong magne_c

    field Watts+16 Image credit: Mysid/R. Smits Magnetic field lines (invisible!)
  11. PULSAR • A neutron star with a very strong magnetic

    field • Shines bright beams of light out of its north and south magnetic poles Watts+16 Video credit: NASA
  12. Fancy PULSAR Some types of pulsars might have a twisted

    magnetic field structure, so they might have multiple poles in different shapes and locations! Watts+16 Video credit: NASA
  13. PULSAR • A neutron star with a very strong magne_c

    field • Shines bright beams of light out of its north and south magne_c poles • Beams of light + spinning = pulses (like a lighthouse) Watts+16 Kramer gif Image credit: M. Kramer; H.Craft/P.Saville
