"Science" has now many definitions. My personal understanding of "science" is this: [this video]

Feynman's lectures on the character of physical law should be something everyone sees in school. In general we look for a new law by the following process: first we guess it, then we compute the consequences of the guess... and then we compare those computation results to experiment. If it disagrees with experiment it is wrong. In that simple statement is the key to science. It doesn't make a difference how beautiful your guess is. It doesn't make a difference how smart you are, who made the guess, or what his name is. If it disagrees with experiment its wrong, that's all there is to it. Notice however that we never prove it right... In the future there could be a wider range of experiments,

Science is about basic understanding. Monkey see, monkey do. Input A yields outcome B. We get that understanding this way: [this video] I love that whole series of lectures. They are his Cornell introduction to physics lectures and are a gold mine of basic scientific type thinking. So far, science has not increased our knowledge of truth. That's damn tough to come by. What it has done is very significantly expanded our understanding of the world. Our theories are far more predictive in far more contexts than ever! But, that is it! Monkey see, monkey do. Engineering is all about applying that understanding to solve problems in robust, efficient, safe ways.

[this video] < have an explanation by Feynman on the scientific method. (Feynman is a great teacher!) The whole video is pretty good, and the specific point starting with "You cannot prove a vague theory wrong" is explained around 5:10.

Strong rec ddingus · 2024-09 · on “Is accidentally stumbling across the unknown a key part of science?”

Yes! Nature is the authority. Our scientific method allows us to pose any question and it allows us to gain understanding when said questions are testable and repeatable. Notably: we never get to know anything, sadly But, we do understand monkey see, monkey do style: do A get B Observing nature is key, but not the only key. Observation coupled with mathematics allows us to process observation analytically, and all of that allows us to... Guess and test! Richard Feynman taught this at Cornell, and it remains one of the best explanations of the scientific method around because it is clear, funny and short, to the point: [this video] And just another thing to add here, and that is science is not a b

" the only difference between spiritual beliefs and academic ones is the language used to express them" I'm not sure what is meant by "academic", but if it's a synonym for science then I disagree. Watch the link below (feynman on the scientific method), a little after the 5 minute mark he talks about the problems of "vague" theories. This vagueness is where spiritual beliefs usually diverge from scientific beliefs. [this video]

Why not destroy such sceptics (on HN or anywhere else) regarding the rate of climate change and related topics? All you have to do is demonstrate that the data presented by them & their interpretation is garbage, nonsense or whatever else you want to call it. Must surely be easier than presenting a classic logical fallacy - argument by authority and thinking that nails it. Maybe the link is indeed total rubbish but talking about man-hours and 'trained PhD's' is irrelevant. Feynman explains nicely: [this video] . Science is a matter of a debate on facts versus theory not a vote-counting appeal on behalf of the supposed position of an ill-defined electorate.

Here is the definition. Many of the ideas on the parent thread fall into the "you can not prove a vague theory wrong". [this video] I have no idea what you mean by "an arbitrary probability of 95%+"
