Do you believe in classical, Newton, mechanics?

Click For Summary

Discussion Overview

The discussion revolves around the acceptance and belief in classical Newtonian mechanics compared to quantum mechanics. Participants explore the philosophical implications of belief in scientific theories, the limitations of Newtonian mechanics, and the historical context of physics theories.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Meta-discussion

Main Points Raised

  • Some participants express skepticism about the term "believe" in relation to scientific theories, suggesting alternatives like "accept" or "agree after examination of evidence."
  • Others argue that while Newtonian mechanics is useful, it has limitations and does not account for extreme cases, necessitating other theories like quantum mechanics and relativity.
  • A participant notes that Newton did not understand the mechanism of gravity, which was later addressed by Einstein's theories and the concept of gravitons in M-theory.
  • One participant expresses a preference for the warped spacetime model over the graviton concept.
  • Another participant critiques Newton's laws, suggesting that Archimedes provided a better foundation for physics and that Newton's laws are merely partial interpretations.
  • There is a discussion about the nature of beliefs in science, with some asserting that everyone holds beliefs, as absolute certainty is unattainable.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the validity of Newtonian mechanics versus other theories, and multiple competing views remain regarding the nature of belief in scientific theories.

Contextual Notes

Some participants highlight the limitations of Newtonian mechanics in extreme scenarios, while others emphasize the philosophical aspects of belief and language in science. There are unresolved discussions about the definitions and implications of terms used in the context of scientific acceptance.

I wonder, is there out someone disbelieving quantum mechanics but accepting the concepts and statements of Newtonian mechanics? I would like to hear such standpoints.
 
Physics news on Phys.org
Physics and science in general is based on observation and theories developed from these observations. Unlike religion, belief has nothing to do with it. Newtonian mechanics works most of the time and is very useful. However, there are extreme cases where it doesn't work. That is why physicists (Einstein, et al) needed other theories (quantum, relativity) to account for these situations.
 
Don't forget that Newton had no idea how gravity worked. It was not until einstein with his spacetime "web" or "grid" did anyone really understand how gravity worked.

And now...
M-theory says that there is a particle called a gravitron that is responsible for gravity.
 
Newtonian mechanics postulates the existence of instantaneus velocity and momentum, for an example.


(ah, the graviton idea was previous to M-theory)
 
The word believe does not effectively describe my attitude towards any scientific hypothesis or theory, period.
 
I vote to toss that graviton thingy, warped spacetime is much more pleasing.
Just thinking about all those particles flying between the planets ...

What about "Do you accept the axioms of...?", or perhaps
"After examination of the empirical evidence, I tend to agree/disagree with the postulates of...?"

Everyone has beliefs be they about science or anything else because no one knows anything with 100% certainty. The root of all creativity comes from beliefs and creativity has a lot to do with physics. Just lighten up people, you're not going to look illogical or like a zealot for using the word "believe."


Anyways I have my quarrels with all of them but I wouldn't really dismiss any of them as completely wrong.
 
I voted against Newton.
I even have a page on it here:

I cannot accesss my page. I don't know why is that. Geocities simply requires me to preregister??
unfortunately, nobody gives a damn.

Every Newton's law is only partial interpretation of the law of lever.
I just think Archimedes does physics better than Newton.
In fact Archimedes is the 1st ever physicist.
Despite that the lever is never mentioned in the educational process.

Hmm, nobody has a vocabulary coinciding 100%, in all the semantic flavourings, with other person. But does that imply that vocabulary, that each word, is a belief?
