Discussion Overview

The discussion revolves around the nature of Newton's law, specifically the equation F=ma, and the concept of proof in scientific contexts. Participants explore the validity of Newton's laws, the nature of scientific evidence, and the challenges of defining and measuring force.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants express skepticism about the concept of "proof" in science, suggesting that valid evidence is more relevant than mathematical proof.
  • One participant argues that the validity of Newton's laws can be evidenced by practical outcomes, such as the stability of structures and the successful prediction of celestial movements.
  • Another participant introduces the idea that gravity could be considered entropic, implying an alternative perspective on the nature of force.
  • A participant questions the meaningfulness of the definition of force as F=ma, suggesting that definitions cannot be proven and expressing confusion about alternative theories like those of Milgrom and Verlinde.
  • There is a mention of measuring force through mass and acceleration, with a reference to practical tools like a spring scale to illustrate the measurement process.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the nature of proof in science or the validity of Newton's laws. Multiple competing views are presented regarding the definition of force and the implications of alternative theories.

Contextual Notes

Participants highlight the limitations of definitions and the challenges in proving scientific concepts, indicating that the discussion is influenced by differing interpretations of evidence and measurement.

a Newton's law states that : F=m.a , but I realize that it belongs to our sense , but may be someone know more about this . if you have any explanation or proof , let me know :)

Forget about Newton's laws. Think about how you "prove" anything in science!

There is no such thing as "proof" as rigorous as that in mathematics, i.e. a logical proof. There are such a thing as "valid" evidence! The fact that your house still stands is an evidence for the validity of Newton's laws. The fact that we can actually map and predict the location of celestical bodies (i.e. we shoot a space capsule here on earth, and months and years later, actually reach a planet that wasn't at that location months and years earlier) is another evidence for the validity of Newton's laws.

Ofcourse you can. Just say that gravity is entropic.

What this guy said.

In logic,
there are direct proofs (if a goes to b and b goes to c then a goes to c),
proofs by contradiction (you assume the opposite of what you want to prove, then work to find the contradiction in that),
and proofs by induction (Tricky to explain in a single line. look this one up.)
You can look those up.

The types of proof that are not valid that are constantly used are:

Proof by superiority = "The King said the sun is blue.. so the sun is blue." The story of "the emporer has no clothes" is a story that attempts to explain to children that this is not proof.

Proof by Precident.
"We have been doing this for 25 years this way... "
It could have been wrong for 25 years... or incomplete, but if that is all you knew, then that's all you knew.
 
Tell me if I’m wrong. The formula f=ma is a definition of force. You can’t prove a definition. You can ask, is it meaningful? I think it is not. Can you measure force? Well, if you can measure mass and if you can measure the acceleration then you can measure the force. Otherwise I don’t think you can. So I don’t understand Milgrom and I don’t understand Verlinde. What are they doing?

Ever seen a spring scale?
