Interesting. Isn't that just problem solving? If yesterday's problems are unsolved by today, aren't they just today's problems?

  I read it as: - Today, I need to predict tomorrow’s weather. - Yesterday I made some measurements of the (temperature, pressure, etc) conditions that I need for today’s prediction. - Yesterday it was impossible to know what measurements I’d optimally need to take for today’s forecast. - Today, I can (quantumly, probabilisticly) go back in time and make sure I have the optimal set of measurements for today’s prediction. - I can’t change anything that happened between yesterday and today, but I now have better information I can use to change tomorrow.

    So you can measure the past, but not change it?

    If you already know the optimal set of measurements why not skip the whole traveling back in time part and just change tomorrow today?

      > The problem is that, only after the interaction does the metrologist learn which input would have been optimal.
