Hello, I’m Hanrong Zhang. Currently, I am a master’s student in journalism at the School of Journalism and Communication, Nanjing University. My advisor is Associate Professor Chengjun Wang. My research interests lie in the field of computational social science. While I acknowledge that I still have much to learn in the realm of academic research, I am determined to put in my best efforts.

I completed my undergraduate studies at Nankai University, where I had the pleasure of getting to know almost every cat on campus. In my free time, I enjoy photography, playing the piano, stargazing. Welcome to my personal website to know more about me! Link to your favorite subreddit.

Can Quantum-Mechanical Description of Physical Reality Be Considered Complete?

In a complete theory there is an element corresponding to each element of reality. A sufficient condition for the reality of a physical quantity is the possibility of predicting it with certainty, without disturbing the system. In quantum mechanics in the case of two physical quantities described by non-commuting operators, the knowledge of one precludes the knowledge of the other. Then either (1) the description of reality given by the wave function in quantum mechanics is not complete or (2) these two quantities cannot have simultaneous reality. Consideration of the problem of making predictions concerning a system on the basis of measurements made on another system that had previously interacted with it leads to the result that if (1) is false then (2) is also false. One is thus led to conclude that the description of reality as given by a wave function is not complete.
