X-Ray crystallography is nowadays an accurate and rapid method of determining conformation in the crystal lattice, which conformation usually corresponds to the preferred conformation in solution.

Many transition states have a well-defined preferred geometrical requirement.

Every chemical reaction has a transition state.

We were making the first step out of the age of chemistry and physics, and into the age of biology.

I don't think anyone would look at Colombia today and say that it is failing. This positive outcome is an example of the effective application of smart power - it is succeeding.
