SUMMARY

Quantum physics is essential in various fields, including electronics, engineering, chemistry, and astrophysics. It underpins the functioning of semiconductors, which are crucial for modern technology. Quantum mechanics also plays a vital role in understanding nuclear fusion and stellar phenomena, such as white dwarfs, providing insights that classical mechanics cannot. Without quantum physics, advancements in technology and scientific understanding would be significantly hindered.

PREREQUISITES
  • Basic understanding of quantum mechanics principles
  • Familiarity with semiconductor technology
  • Knowledge of nuclear fusion processes
  • Awareness of astrophysical concepts, particularly related to stellar phenomena
NEXT STEPS
  • Research the role of quantum mechanics in semiconductor technology
  • Explore quantum tunneling and its implications for nuclear fusion
  • Study the applications of quantum mechanics in chemistry
  • Investigate the relationship between quantum mechanics and astrophysics, focusing on white dwarfs
USEFUL FOR

Students, researchers, and professionals in physics, engineering, and chemistry who seek to understand the foundational role of quantum physics in modern technology and scientific advancements.

I know absolutely nothing about physics. I know that classical mechanics is used in engineering and whatnot, but could anyone explain the uses of quantum physics?

It is used in electronics, engineering, other scientific fields, and in some way is related to almost every field out there. Without quantum physics, I don't think we would know how a semiconductor works, and would probably be far less advanced technologically.

What about astronomy and astrophysics?

I would say most likely. I'm not sure the process behind nuclear fusion and other stellar phenomena would be understood as well as they are without quantum mechanics.
 
"Providing the underlying theory for almost all of chemistry" is also a pretty significant use, IMO. :)

Agreed!

Nuclear fusion would practically impossible without a bit of quantum tunnelling!
