Backreaction: What is a theory, What is a model?

Trochę na temat modelu i teorii. Nie zawsze sobie dobrze zdajemy sprawę ze wszystkich implikacji używania tych pojęć…

The word “theory” has a common root with “theater” and originally seems to have meant “contemplation” or generally a “way to look at something,” which is quite close to the use of the word in today’s common language. Scientists adopted the word, but not in any regular way. It’s not like we vote on what gets called a theory and what doesn’t. So I’ll not attempt to give you a definition that nobody uses in practice, but just try an explanation that I think comes close to practice.
