As computer structures get smaller and smaller, quantum rules start to create difficulties. Suppose electrons move through a channel in a microprocessor. If we know that an electron is somewhere along the 50 nm length of the channel, what is Δνx? If we treat the electron as a classical particle moving at a speed at the outer edge of the uncertainty range, how long would it take to traverse the channel?
