Why do you have to wrap x in Dynamic if you want the slider to update it?
i.e. Slider[Dynamic[x]] instead of Slider[x]
It seems to me that Slider would be able to update the value of x without the Dynamic. So in a notebook like this:
The slider should update x and these new values should be reflected in the dynamic expression.
Obviously this isn't how mathematica works because that program doesn't work...
Could anyone explain the underlying mechanism here?
Thanks a lot!
