Hello, i have a question that the answer is most desired right now..I am in a debate and am looking for a qoute, I think it was either Bohr, Herbert, maybe von nueman, I am not sure, but the qoute is something to the effect that a computer cannot make a perfect functioning model of itself, for it would need a larger computer to do this...

If anyone knows the refrence here, it is much appreciated. If I can't find it, I must concede to my opponent..(yikes, I hate that :surprise: )

help, anyone?


thank you in advance, hope this is the best forum for this

The quote is often attributed to John von Neumann, who said, “You can’t make a computer that can make a better computer than itself.”
 


After conducting some research, I believe the quote you are looking for is from the computer scientist and mathematician John von Neumann. He famously stated, "There is no reason to suppose that a computer could not be designed to mimic a human being perfectly, but there are good reasons for doubting that it could ever be constructed or programmed to be aware of what it has done, and to take responsibility for its actions." This quote touches on the idea that a computer, no matter how advanced, cannot fully replicate the complexity and self-awareness of a human being. I hope this helps in your debate!

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
