how does it come a major research institution was unaware of the difference?

Really??

So, how was the United States able to produce the atom bomb?

They were aware of things nobody else was aware of!!!

I see you are avoiding answering the question. Please do your best!! It is ok and I expect you do not know the answer.

Tell me, what is the difference between these too formula's?

They express the same thing.
