When I read this passage from Feynman, some of the main points he made stood out
clearly. First he claims that scientists determine the validity of their rules about nature in three
ways: Precise calculations, general trends, and rough approximations. When nature is arranged in
a simple way, precise predictions can be used. If not every detail can be uncovered, then general
trends and patterns can be utilized to make generalizations. If all of the above fails to surface,
then rough approximations can be employed, capturing the overall sense of what’s happening.
He also stresses that in physics, it's not about organizing them in neat categories, but rather the
attempt to incorporate everything in a unified system--a larger understanding. He admits how
this process could be nevertheless messy: Even when scientists succeed in unifying some areas,
new discoveries like the X-ray continuously complicate matters for them, sometimes prompting
them to be more considerate, other times forcing them to abolish their ideas completely and start
from scratch.
What surprised me was how the author described science like a game of chess. AScience,
as I perceived, was a serious and exact subject, but the analogy of it with chess made it seem
recreational, and even a bit uncertain–just like when you can;’t predict your opponent’s moves. I
also found it interesting that sometimes rules work for a long time and suddenly break down.
Exceptions continuously reshape theorems and rules, and what is considered permanent truths
can fail to explain these anomalies. But rules that we find out now–like Newton's laws, would
have to comply until we find otherwise. Through this revelation, science was made more like an
ongoing adventure, where scientists are explorers, updating maps and books about distant worlds
and the animals that inhabit it.
There were some obscure words in the text, especially the word
amalgamate. It made me pause because I’ve never encountered the word before, but then combining
the context I knew that it probably meant coalesce or merge.
As for questions, I wonder if science would eventually come down to one point, or if new
discoveries and explorations of new realms limit that possibility: maybe nature is too complex
and filled with loose ends that can’t be explained. This also makes me wonder about the
scientists’ works: if they know that what they discover might ultimately be overturned by new
discoveries, would they be discouraged by that? The perseverance of scientists astound me:
unknown of what is ahead of them, but still determined to push towards unification.
