Borns interpretation of the
wave function
It is not possible to measure all properties of
a quantum system precisely
Max Born suggested that the wave function
was related to the probability that an
observable has a specific value.

Why learn grammar?
Yes, you already know how to talk English. Learning grammar allows us to have power
over our language to manipulate it for our advantage.
Grammar may not seem useful now, but it is a skill that needs to be learned, just as its
