    Imaginary
In summary, the conversation discusses the implications of the real world being "real" and not "imaginary." It is stated that wave functions and expectation values are real quantities, while operators are not. The equation Ψ* = Ψ is also mentioned, along with the fact that energy levels are real. There is some disagreement about whether wave functions can have an imaginary component.

Homework Statement


The real world is "real" and not "imaginary", what does this imply?

1. wave functions are real quantities
2. expectation values are real quantities
3. operators are real
4. Ψ* = Ψ, where Ψ denotes a wave function
5. energy levels are real
6. wave functions cannot have an imaginary component

Homework Equations

The Attempt at a Solution


I'm pretty sure 4, 5 and 2 are correct, energy levels are essentially expectation values and I'm pretty sure that is real, 3 and 1 are wrong, operators don't have a meaning by themselves, and waves aren't quantities, and not sure about 6, I believe there are actually some values with imaginary parts that still correspond to the real world.. but I might be wrong

4 is not correct. Wave functions can have imaginary values and often do.
 

Related to Are All Aspects of Quantum Mechanics Real or Imaginary?

1. What is the difference between the "real" world and the "imaginary" world?

The "real" world refers to the physical world that we experience through our senses, while the "imaginary" world is a fictional or abstract world that exists only in our imagination.

2. Can something from the "imaginary" world become real?

While ideas or concepts from the "imaginary" world can inspire and influence real life, they cannot physically manifest in the "real" world.

3. How does the "imaginary" world impact our perception of the "real" world?

The "imaginary" world can shape our thoughts, beliefs, and perspectives about the "real" world, but ultimately our perception is based on our physical experiences and interactions.

4. Is the "real" world more important than the "imaginary" world?

Both the "real" and "imaginary" world hold value and importance in different ways. The "real" world is essential for our survival and daily functioning, while the "imaginary" world allows for creativity, imagination, and exploration of possibilities.

5. How can we distinguish between the "real" world and the "imaginary" world?

The "real" world can be verified through our senses and scientific evidence, while the "imaginary" world is subjective and cannot be proven through physical means.
