- kinetic energy, T = 1/2 mv^2
multiplying and dividing m, we get,
T = (1/2 m^2.v^2)/m
= (p^2)/2m ( p= mv)
- Unit of power is watt, which is
watt = joule/second
Unit of Plank constant is joule.second
so, watt.(second)^2 = (joule/second).
(second)^2 = joule.second
which is, in fact, the unit of Plank’s constant. - <ΨIΨ> = 1 is the property of
orthonormality. For example, in cartesian
co-ordinate, i.i = 1
<ΨIF> = 0 is the property of
orthogonality, where Ψ and F are two wave
functions. And they are orthogonal.
For instance, in cartesian co-ordinates, i.j =
0 - Schrödinger’s cat experiment uses
quantum superposition as its basis idea.
The fact that the cat can be both alive and
dead at the same time is an analogy of
quantum superposition. - Quantum computers use qubits the
same way our computers use binary
numbers 0 and 1. But quantum computers
use the principle of quantum superposition.
Therefore, 0 and 1 exist in a superposed
state.
