Click For Summary

Discussion Overview

The discussion centers on the practical applications of breakthroughs in quantum mechanics, exploring various fields such as electronics, materials science, and medical technology. Participants share examples and implications of quantum mechanics in real-world scenarios.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants highlight the semiconductor industry, lasers, and medical imaging technologies like MRI as significant applications of quantum mechanics.
  • Others mention the impact of quantum mechanics on solid state physics, nano-physics, and the development of devices such as tunnel diodes.
  • One participant claims that a substantial portion of the American economy relies on quantum mechanics.
  • There are assertions that modern electronics, including LEDs and computers, owe their existence to quantum mechanics, with a suggestion that over 50% of everyday items are influenced by it.
  • A participant introduces nuclear power as a less obvious application, emphasizing the quantum nature of nuclear decay and its implications for reaction control.
  • Discussion includes the potential future applications of quantum technology, such as quantum computers and advancements in nanotechnology.
  • Another participant notes that quantum mechanics plays a role in minimizing device sizes and in the analysis and simulation of device structures.
  • A newcomer seeks resources for understanding quantum wire structures and their physics, indicating a desire for foundational knowledge in the area.

Areas of Agreement / Disagreement

Participants generally agree on the significance of quantum mechanics in various applications, but there are differing opinions on the extent of its impact and the characterization of physics without quantum mechanics. Some statements are contested, particularly regarding the implications of quantum mechanics on the triviality of classical physics.

Contextual Notes

What are some ways that breakthroughs in quantum mechanics have been applied to real world applications?
 
Physics news on Phys.org
Many things for sure.

How about development of the entire semiconductor industry which has clearly had major impacts on technology, and lasers...

/Fredrik
 
The big three I can think of are transistors (electronics), lasers, and medical scans (MRI, etc).
 
Almost everything that involves Atoms and Molecules. Solid state physics (materials), nano-physics.
 
I especially like this practical application:

http://en.wikipedia.org/wiki/Tunnel_diode

wikipedia.org said:
In the tunnel diode, the dopant concentration in the P and N layers are increased to the point where the reverse breakdown voltage becomes zero and the diode conducts in the reverse direction. However, when forward-biased, an odd effect occurs called 'quantum mechanical tunnelling' which gives rise to a region where an increase in forward voltage is accompanied by a decrease in forward current.

.
 
Apparently more than one third of the American economy relies on quantum mechanics!
 
Knowing why the next time you open your oven, there wouldn't be infinite energies shooting at you? just kidding..

As for the question:
I guess LEDs, computers, all modern electronics (the one who invented the giantmagneto thing just got Nobel prize some time ago), superconductor, a fundamental understanding of chemistry... well, as people have said, solid state physics really has had a gigantic impact on our world and probably more than 50% of the things you use involve inventions that wouldn't have been there without quantum mechanics. Also, physics would be quite trivial and silly without quantum mechanics.
 
essentially the entire modern world as you know it

now that's an absurd statement. you obviously don't know about classical field theory
 
Nuclear power would be a not-so-obvious application; nuclear decay is an intrinsically-quantum mechanical phenomenon, and you need to know about collision cross-sections etc. to control reaction rates.

The next generation of nanotechnology, quantum computers, etc. might turn out to be quite fun too :biggrin:

Quantum mechanics is responsible to minimize the device size...
Analysis of device structures can be done through the quantum mechanics...
Quantum mechanics is used in the simulation of the device structures

Hi all,
I am ulhas..
I am new to pf...
I will be working on simulation of quantum wire structures for lasing action...
And now I am seeking for free Ebooks or sites which are dedicated for the quantum structures.
Basically I am looking for the physics of the quantum structures...

Thanks in advance...
