SUMMARY
The discussion centers on applying the uncertainty principle to demonstrate that electrons with energies in the range of a few electronvolts (eV) can be confined within atomic dimensions, specifically 0.1 nm. The relevant equations include the position-momentum uncertainty relation, \(\Delta x \Delta p \geq \hbar / 2\), and the energy-time uncertainty relation, \(\Delta E \Delta t \geq \hbar / 2\). The value of \(\hbar\) is given as 6.58 x 10-16 eV·s. The challenge lies in deriving the energy-position uncertainty relation to complete the proof.
