Student or Learner
please tell me is there any difference bewteen "be excited with sth" and "be excited by sth" as i do see people replace "with" instead of "by" sometimes.
Here is Context of "excited by":
Scientists excited by Big Bang machine experiments.
and followed with "excited with":
People are excited with new Gadgets.
I wonder whether it's ok to say
"Scientists excited with Big Bang machine experiments."
"People are excited by new Gadgets."
If "excited with/by" are able to be replaced with each other in the situation above, when they can not do that? could you show me some examples and tell me why they can not do that.
