(my English is bad,so please try to understand. :)
As we know that bohr said we could not know anything without detecting.To talk about anything of a particle without measuring is meaningless,and we don't know what exactly happened during the process.
Someone think maybe it is just there ,you just don't know.But bohr said it is wrong.
And now I am thinking about something that confuse me.Considering bohr is right,according to Heisenberg's uncertainty principle,we can't konw exactly the position and the momentum of a particle at the same time,and the process of motion is unkonw (or meaningless or something).then what is velocity (speed) at all.Without the defination of velocity (speed),what is momentum.
Thanks.
