Episode notes
INSIGHT

Measuring Star Distances

  • Measure star distances using parallax, the change in a star's apparent angle as Earth orbits the Sun.
  • This change helps calculate distance in parsecs or light-years.
INSIGHT

Refractive Index and Heating

  • Higher refractive index doesn't directly cause more heating, as photons are re-emitted in transparent materials.
  • Heating occurs when photons are absorbed and their energy converts to kinetic energy.
ANECDOTE

Slowing Light

  • Stephen Wolfram once saw materials slowing light enough for visible travel.
  • These materials used trapped atoms in a uniform state, similar to Bose-Einstein condensates.
