Because understanding is almost always easier than data collection and tool-building. Pure lack of understanding -- having all the data and having no idea what it means -- can keep a problem open for a generation or two. Einstein is famous because he solved a problem in EM physics that was at most 30 years old. Lack of data or meaningful investigative techniques can keep a subject crippled for centuries. Physics went…

I don't have as many examples but here is one. Galileo discovered his principle by conducting very simple experiments with no special tools or a lot of data collection. How do you find the relevant data or build relevant tools if you don't have a clue about what you are supposed to discover? What computer vision needs is mathematics, in my opinion. And math has nothing to do with "data collection and tool-building".…

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...

Yeah, Galileo is a particularly bad example. I believe he had a professional instrument maker working for him full-time. Newton would illustrate the point better.

Galileo didn't invent the telescope, though. What he did do first is use telescopes for astronomy.
