How can reality be non local and its expression be local.

Click For Summary
The discussion centers on the concept of non-locality in reality and its local expressions, prompting questions about its meaning. Participants seek clarification on the topic, indicating a need for specificity in the inquiry. The conversation suggests exploring related concepts such as quantum entanglement and Bell's theorem for a deeper understanding. A resource is provided for further reading on these complex ideas. Ultimately, the dialogue emphasizes the importance of clear communication when discussing intricate scientific theories.

You're going to have to be a bit more specific. It's not really clear what you're asking. Please write in complete sentences with proper punctuation, capitalization, etc.
 
If you want to know about entanglement, nonlocality, Bell's theorem, and the like, you can read the excellent explanation http://quantumtantra.com/bell2.html.
 

Thread 'Two equivalent statements of time reversal symmetric Hamiltonian'

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
