Quantum Behavior As Extreme Classical Behavior

Click For Summary
Quantum behavior cannot be fully explained as an extreme version of classical behavior due to fundamental differences in principles, such as entanglement and non-locality. While classical mechanics can describe some phenomena, it fails to account for quantized properties like spin and the indistinguishability of quantum particles, which lead to different statistical distributions. The Stern-Gerlach experiment illustrates that quantum particles exhibit behaviors, such as spin, that classical mechanics cannot adequately explain. Additionally, the double-slit experiment highlights how observation affects particle behavior, a concept that classical analogies struggle to encompass. Ultimately, quantum mechanics introduces unique phenomena that challenge classical interpretations, indicating a deeper connection between the two realms rather than a simple extension of classical behavior.

As it has already been said, you shouldn't try to derive quantum mechanics with classical intuition. Classical mechanics is quantum mechanics within a limit. In many cases it is straightforward to revive the results of classical mechanics from quantum mechanics.

You keep going to the basketball in a hoop example. The basketball is a wave, but consider its wavelength with respect to the distance it travels and the size of the hoop. Now consider the wavelength of an electron compared to Young's slits.
