Discussion Overview

The discussion centers on the contributions of classical and modern physics to modern civilization, particularly in relation to technological advancements and inventions such as cars, airplanes, and computers. Participants explore the historical significance and interconnections between different branches of physics and their applications.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that classical physics, including mechanics and thermodynamics, has been foundational for many modern inventions, while modern physics has only recently become intertwined with these applications.
  • Another participant argues that the distinction between classical and modern physics is blurred, as modern technology often relies on principles from both fields, such as GPS systems that depend on general relativity.
  • A participant challenges the premise of the discussion, stating that it assumes a direct correlation between specific branches of physics and various inventions without evidence.
  • One post mentions solid state physics as a relevant area, though it does not elaborate on its contributions.
  • Another participant humorously notes that the history of physics involves borrowing concepts across different branches, suggesting that mathematics itself could be seen as a unifying factor.
  • A biologist contributes to the discussion by highlighting the importance of modern medicine, such as antibiotics and vaccines, as significant advancements for civilization.
  • One participant points to classical chemistry, specifically the Haber process, as a critical development that has impacted population growth and food production.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding which branch of physics has contributed more to modern civilization, with no consensus reached on the matter.

Contextual Notes

The discussion reflects a variety of perspectives on the interrelation between different scientific disciplines and their contributions, with some participants emphasizing the historical context and others focusing on specific applications.

Classical or modern physics? Basically, which branch is responsible for all modern inventions: Cars, airplanes, modern sea ships, spacecraft s, microwaves, ovens, computers, televisions, smartphones, etc. (Also, how did we get to the moon, using concepts from classical or modern physics?)

Classical physics is: classical/Newtonian mechanics, electromagnetism, thermodynamics
Modern Physics is: relativity, quantum mechanics, optics, nuclear and particle physics

I don't think you can draw a line nowadays as every car has microchips built in and ships are steered by GR dependent GPS signals. However, overall, I think it is plain old classical mechanics. It ruled our world for thousands of years and only since a century, the two fields became connected. But this doesn't change the fact, that the law of levers is still silently used everywhere and all the time.

Objection! Assumes facts not in evidence!

You question assumes that the same subfield gives us cars and smartphones.

Classical physics...
 
Quite decent part of the history of every branch of physics is about utilizing (aka: stealing:smile:) the math, ideas, solutions from other branches and apply them on different areas.

To sort it out is like tracking back the family tree of an old style guinea pig breeding farm...

Well, if I must pick only one single suspect for this, then it'll be ... mathematics :wink:
 
Hello from the biologists:

Modern medicine (antibiotics, vaccines, etc.) are pretty important inventions to modern civilization too!

I would say classical chemistry, for example the Haber process where fertiliser could be plucked out of the air, feeding populations is the basis of the modern population explosion.
