Let's revisit the idea of the thesis itself. It is a hypothesis, a conjecture, a theorem. The dissertation is a formal, stylized document used to argue your thesis. The thesis must be significant, original (no one has yet demonstrated it to be true), and it must extend the state of scientific knowledge.
Twinning (crystallography). A process in which two or more crystals, or parts of crystals, assume orientations such that one may be brought to coincidence with the other by reflection across a plane or by rotation about an axis.winning of calcite by the pressure of a blade (Baumhauerâs method). If the structural homogeneity of a single crystal is disrupted by a great number of twin formations, the crystal is called a polysynthetic twin (Figure 3).
