Scouring Museums

The transcript discusses the debate on whether quasi crystals are inherently delicate or energetically favored phases. It explores the possibility of forming quasi crystals in laboratories and their natural occurrence. The speaker shares their experience of searching for quasi crystals in museums, highlighting the challenges of distinguishing them from other materials like pyrites. The discussion emphasizes the importance of understanding quasi crystals for both fundamental physics and practical applications.

What was the speaker's approach to finding materials in nature that resemble quasi-crystals?

Explain the confusion regarding the pentagonal shapes observed in pyrites and their relation to crystallography.
