Can Quantum Mechanics Represent The Fact That

Can Quantum Mechanics Represent The Fact That An Electron Finds Itself Approximately In A Given Place And That It Moves Approximately With A Given Velocity, And Can We Make These Approximations So Close That They Do Not Cause Experimental Difficulties?

...separation Of The Observer From The Phenomenon To Be Observed Is No Longer Possible.

The Problems Of Language Here Are Really Serious. We Wish To Speak In Some Way About The Structure Of The Atoms. But We Cannot Speak About Atoms In Ordinary Language.

You May Object That By Speaking Of Simplicity And Beauty I Am Introducing Aesthetic Criteria Of Truth, And I Frankly Admit That I Am Strongly Attracted By The Simplicity And Beauty Of Mathematical Schemes Which Nature Presents Us.
