Introduction to Quantum Mechanics

Click For Summary

Discussion Overview

The discussion centers around questions related to Quantum Physics, its relationship to Classical Physics, and the concept of a unified physics framework. Participants explore the distinctions and connections between different areas of physics.

Discussion Character

  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Bilal Rajab poses questions about where to learn Quantum Physics and its relation to Classical Physics, expressing curiosity about the existence of multiple branches of physics.
  • Another participant suggests that while there is one unified physics, it encompasses various sub-areas that are interconnected, indicating that different fields can share similar mathematical forms.
  • This participant also emphasizes the importance of using appropriate instruments for different measurements, drawing an analogy between weighing scales and the study of different physics domains.
  • They argue that a physicist should have a foundational understanding of all fundamental areas of physics rather than specializing in just one.

Areas of Agreement / Disagreement

Participants express differing views on the nature of physics as a unified discipline versus a collection of distinct areas. The discussion remains unresolved regarding the implications of these perspectives.

Contextual Notes

Participants have not fully explored the assumptions underlying their statements about the relationship between Quantum and Classical Physics, nor have they clarified the definitions of "one single physics" versus multiple branches.

Hi! I am Bilal Rajab.
I have a question regarding Quantum Physics.
From where can we learn about Quantum Physics and what is its relation to Classical Physics?
Why is there not one single Physics...?
Thanks

Here in the US, at various points along the many thousand of miles of US highway systems, there are "weighing stations" that weigh commercial trailer trucks, to make sure they are not overweight and become a safety hazard. Now, do you think these weighing machines can also weigh chemicals in the sub milligrams scale with the needed accuracy? If you drop a grain of sand on such a scale, do you think it will even make a difference on its reading? You have to switch to a more accurate weighing scale, which will have greater accuracy, but you sacrifice the range of weights that you can now measure. A chemical balance is certainly not the equipment you would use to weight a truck, or even a potato.

In other words, you use the proper instrument to do what you want.

There actually is just ONE single physics. But it has many different loose sub-areas. It also means that they are all inter-related and connected. There are forms and mathematics that look similar or even identical in different areas of physics. This is why the study of magnetism and superconducitivity in condensed matter physics gave birth to the Higgs mechanism in elementary particle physics.

This is why students usually get an undergraduate degree in "Physics", not in Classical Physics, not in Quantum Physics, not in Electromagnetism, etc... A physicist is expected to know the basic knowledge of all the fundamental areas of physics, not just one.
