String theory

• How Can You Imagine Curled-Up Dimensions?
  Picture a curled-up dimension as a tiny circular direction at every point in space, like the cross-section of a hose seen from far away.
• What Are Calabi–Yau Moduli Fields?
  Calabi–Yau moduli fields are four-dimensional scalars describing internal geometry; their number and multiplets depend on Hodge numbers and string theory.
