we can know the path an electron takes as it moves through a space,
or we can know where it is at a given instant,
but we cannot know both.
What this means in practice is that you can never predict where an electron will be at any given moment.
You can only list its probability of being there.
In a sense, an electron doesn’t exist until it is observed.
Or, put slightly differently, until it is observed an electron must be regarded as being “at once everywhere and nowhere."

are human as substantial as they looks like?
could feelings have a shape?
