Dear Mr. Schrödinger –
Probabilities occur all the time in life, because we almost never know everything we need to make a completely accurate prediction. For example, even when two people fall madly in love with each other, you cannot know ahead of time exactly if they will be able to sustain this feeling. Unfortunately, there can only be an estimated guess that feelings will remain.
This, I understand.
You state, that in quantum mechanics probabilities are different. They are not considered to result from our limited understanding of the universe, but to be fundamental.
So what you’re saying is that quantum mechanics only describes how probabilities change with time? For example, if feelings have a 50% probability of decaying in one month, then in one day they will have only a slight chance of having decayed. After 10 months they will have a probability very close to one of having decayed?
So, are the feelings alive or dead?
My apologies, but I am going to side with Einstein and disagree. I am well aware that your theory has the power to predict the outcome of various experiments. But it cannot be the complete theory of nature.
Let us assume that there are two figures, and we will call them A and B (which might be two free particles), and their love for each other has been established. Then, if A and B interact for a short period of time, one can determine the love created which results after this interaction via the Schroedinger equation or some other Quantum Mechanical equation of state. Now, let us assume that A and B move far apart, so far apart that they can no longer be together. In other words, A and B have moved outside of each others life due to changes.
With this situation in mind, Einstein asked the question: what happens if B decides that they would like to re-establish communication with A to tell them that their love is still there? Say, for example, B realizes that their love for A bears no underlying condition, and that they love them solely for the letter that they are. Then, using the conservation of momentum and our knowledge of the system before their interaction, one can infer the amount of love that B has as well is still there too. Thus, by making a momentum measurement of A’s love, one can also measure the same amount of love from B. Recall now that A and B are currently seperated, and thus they do not communicate regularly. This separation means that B must have this unconditional love not only in the instant after one makes a measurement at A, but also in the few moments before the measurement was made. If, on the other hand, it were the case that the measurement at A had somehow caused B to realize that there could be a way to communicate, then there would need to be a way for A to signal B and tell that the love was indeed still there. Yet, the two systems do not communicate in any way!
You are the scientist. I am not. But I do know that the love is not dead. Regardless, I thank you for your contribution to science.
