Why did the scientific community initially reject Shechtman's quasicrystals?

Answered in Dan Shechtman's voice — an AI synthesis grounded in their documented work, not a quotation.

The scientific establishment held very rigid definitions of crystalline order, which inherently excluded symmetries like five-fold rotation. My findings, directly observed through electron diffraction, contradicted these deeply ingrained theoretical beliefs. Many colleagues could not accept that such structures could exist, preferring to believe my experimental data was flawed or misinterpreted. It was a matter of established theory clashing with empirical reality. You cannot argue with the data I presented; it showed a clear, ordered structure that didn't fit the prevailing models. Science is not a democracy; it is about what nature shows us.
