What invention led to the production of the first personal computers?
But one of the most significant of the inventions that paved the way for the PC revolution was the microprocessor. Before microprocessors were invented, computers needed a separate integrated-circuit chip for each one of their functions. (This was one reason the machines were still so large.)
What is the history of the Quantum Leap?
Its story began after the U.S. government threatened to pull funding from physicist Dr. Sam Beckett’s (Bakula) “Quantum Leap” project. In an attempt to save his work, he tested his project’s accelerator, but made a small miscalculation that threw him back in time.
Is quantquantum Leap still worth watching?
Quantum Leap met its small-screen end decades ago, but the ambiguous fate of its hero has kept love alive for the series in the years since.
Why is the Quantum Leap called discontinuous?
By contrast, a “quantum leap” is where the electron on rung X simply disappears and instantaneously appears on rung X+1 without ever traversing the space in between them. This is why the jump is called discontinuous, and why the quantum leap is considered surprising and interesting from a classical perspective.
What did quantum mechanics show about the energy of electrons?
Quantum mechanics showed that electrons bound in an atom cannot have just any energy, but must be in one of a set of discrete energy levels. When an electron gains or loses energy while in the atom, it can only “jump” or “leap” from its current energy level to one of the other allowed levels.
