A Quote by Werner Heisenberg
The uncertainty relation does not refer to the past; if the velocity of the electron is at first known and the position then exactly measured, the position for times previous to the measurement may be calculated.

The uncertainty principle refers to the degree of indeterminateness in the possible present knowledge of the simultaneous values of various quantities with which the quantum theory deals; it does not restrict, for example, the exactness of a position measurement alone or a velocity measurement alone.
We compel the electron to assume a definite position. We ourselves produce the results of the measurement.
Morality—like velocity—is relative. The determination of it depends on what the objects around you are doing. All one can do is measure one's position in relation to them; never can one measure one's velocity or morality in terms of absolutes.
Any measurement must take into account the position of the observer. There is no such thing as measurement absolute, there is only measurement relative.
Now if this electron is displaced from its equilibrium position, a force that is directly proportional to the displacement restores it like a pendulum to its position of rest.
We're on the same radius from the Earth, and then we start to swing around to where we're ahead of them on the velocity vector, so we come in relative to the station from this forward velocity position and dock on to the forward end of the Lab.
If we ask, for instance, whether the position of the electron remains the same, we must say 'no'; if we ask whether the electron's position changes with time, we must say 'no'; if we ask whether the electron is at rest, we must say 'no'; if we ask whether it is in motion, we must say 'no'.
The movement of a single atom from one known position to another known position changes an experience from nothing to overwhelming. This means that mind and matter at the quantum mechanical level are all spun together.
The superior man does what is proper to the station in which he is; he does not desire to go beyond this. In a position of wealth and honor, he does what is proper to a position of wealth and honor. In a poor and low position, he does what is proper to a poor and low position.
When I was at art college, the teachers who helped me were not the ones I agreed with, or the ones who encouraged me, but the ones who took very strong positions. Because if someone does that, you can find your own position in relation to it: what is it that I don't agree with? In the studio I want to articulate a position clearly enough so that other people can use it - or chuck it away if they don't want it.
The more precise the measurement of position, the more imprecise the measurement of momentum, and vice versa.
The relation of color and the relation of proportion are both based on the relation of position.
In the United Nations, when China entered, we voted on the same position, and since then we have maintained the same position, that position has not changed.
Social progress can be measured exactly by the social position of the fair sex.
The character of greatness must be measured in two ways, else the measurement is flawed. First, and by far most popular of all, is by one's ability to succeed in times of trial where others may fail. But of no less importance, and perhaps foundational to any form of greatness, is one's willingness to start over in spite of failure, when success seems farthest away.
As Israel prepares to enter, my position is well known. It is one that I have taken at previous Olympics. It is wrong that the IOC refuses to have a minute's silence for Israeli athletes that were slaughtered in Munich.
