In a previous lifetime, I went to a symposium and one of the speakers referenced a paper written by an Applied Mathematics Doctoral candidate from Oklahoma State University.
The context of the problem the Doctoral candidate was working on revolved around the active control of wing-flutter on aircraft. If it were possible to sense vibration modes with an accelerometer on each wing, then perhaps tiny control surfaces could be tweaked to dampen out the kinetic energy before it built up to dangerous levels.
The key finding of the Doctoral candidate was that in spite of everybody's hopes and gut feel, every mode required a dedicated accelerometer, that nothing magical happened by flipping measurements into the frequency domain.
In real life, what it means is that if you have two pieces of information then you cannot draw three, independent conclusions from it. You might draw two conclusions that are different than my two conclusions and that is Kosher. What is not Kosher is for me to combine your conclusions with mine.
Former-Senator Harris bobbled the interview question "When will you visit the border?" twice in just a few days.
Conclusion One: Former-Senator Harris is extraordinarily rigid. She shows very little ability to deviate from her set-piece battle plan during interviews and from day-to-day
Conclusion Two: As of 8:00 AM, EST today she does not have a plan to visit the border and probably does not have anybody assigned to that task.
