How can you say Galileo didn't use tools? He invented the telescope fer God's sake. He timed the descent of falling objects by hiring musicians to keep a beat (no watches). When he couldn't time things, he built ramps and arches to compare things side by side. Much of his machinery was didactic because he often needed to demonstrate his ideas to the courtiers who supported him. We credit him with the invention of the experimental method today because described them in language reminiscent of geometric proofs.

I agree with you about the CV thing, though. We should talk sometime...
