It has always seemed to me extreme presumptuousness on the part of those who want to make human ability the measure of what nature can and knows how to do, since, when one comes down to it, there is not one effect in nature, no matter how small, that even the most speculative minds can fully understand.
Measure what is measurable, and make measurable what is not so.
Interpretation
What this quote means
Galileo emphasizes the importance of quantifying and analyzing what can be measured while also striving to understand that which is not easily quantifiable.
In this quote, Galileo Galilei advocates for a systematic approach to understanding the natural world. He suggests that we should focus on measuring aspects of reality that can be quantified, while also applying creativity and innovative thinking to make sense of those elements that are abstract or difficult to measure. This reflects the core of scientific inquiry, where empirical evidence and observation form the basis of understanding.

Intellectual-property rules are clearly necessary to spur innovation: if every invention could be stolen, or every new drug immediately copied, few people would invest in innovation. But too much protection can strangle competition and can limit what economists call 'incremental innovation' - innovations that build, in some way, on others.
