Catalysts offer the promise of making chemical transformations far less polluting.

Truth titillates the imagination far less than fiction.

Far less envy in America than in France, and far less wit.

It was a far less scientific process back then.

Catalysts are the conductors who choreograph the chemical dance that results in the formation of new structures.

There are risks and costs to action. But they are far less than the long range risks of comfortable inaction.
