 
 <prompt> Which physical property get one transition point wey dem name after one popular female scientist? Based on the question wey dey above, write one context wey get the answer. E fit be 1 - 20 sentences. Context: <response>: Similarly, group theory dey help predict di changes wey dey happen for physical properties wen material dey undergo phase transition, for example, from cubic to tetrahedral crystalline form. One example na ferroelectric materials, where di change from paraelectric to ferroelectric state dey happen for di Curie temperature and e dey related to change from high-symmetry paraelectric state to lower symmetry ferroelectric state, wey dey come with soft phonon mode, wey be vibrational lattice mode wey dey go to zero frequency for di transition.
