    I Rigorous: Where is the Quantum System Prior to Measurement?

    I don't have much knowledge of quantum mechanics, I hope you'll forgive my meddling. Probability 1 for one position means that all position is false, except for this position. Assigning only 0 and 1 isn't appropriate when we're dealing with a superposition where multiple positions are possibles...

    I Math of Electron Double Slit Experiment

    I'm looking for a good derivation of the "wave" patterns in this experiment. I suppose that if wave-particle duality is an obsolete idea, there must be a derivation from quantum mechanics that gets close results. Thanks in advance

    Java Why is the do-while loop in my Java code printing '9'?

    I know that. I learned while and do-while yesterday, so this program was just to synthesize the content. Thanks

    Java Why is the do-while loop in my Java code printing '9'?

    I will remind to do this for the next time. thanks:smile:

    Java Why is the do-while loop in my Java code printing '9'?

    I wrote ad = 5; before do loop and it worked. Thank you very much!

    Java Why is the do-while loop in my Java code printing '9'?

    int bd= 15; int ad= 5; while(ad!=9){ System.out.println(bd); ad++; bd++; }//output 15,16,17,18 do { System.out.println(ad); ad++; }while(ad<=9);//output 5,6,7,8 thanks for the help

    I Simultaneous measurements of 1 observable

    Hi. I'm new to the forum and and I am currently studying quantum mechanics. According Sakurai, page 24, "When the measurement is performed, the system is" thrown into" one of eigenstates of observable". This raised some questions for me: Is possible two measurements simultaneous of one...
