Hi, I am new to this forum. I suffer from asperger's syndrome, so I am not very good at grasping stuff. I am very slow, so please be gentle. I've heard that particle is something that's localized in space and time. Does that mean a table, for instance, can be considered a particle? But what's a wave, what does it mean when they say it's spread out in space? I am finding it hard to understand that, perhaps, some examples might help. Is a wave something that exists in two different points in space at the same time? Some simple examples may help me understand this. Thanks in advance.
