Quantum mechanics is a probabilistic theory that does not describe individual events. Yet when we perform a single measurement, we find a well-defined outcome. This apparent contradiction, known as ...

Biology has always been an unruly science. Cells divide when they want to. Genes switch on and off like temperamental lights.

This morning on BBC Radio 4, the mathematician Roger Penrose, physicist Basil Hiley, and philosopher Simon Saunders had a lively discussion about the “measurement problem in physics” with broadcaster ...

As an applications engineer, I hear about plenty of test and measurement problems: “What’s wrong with my instrument? I keep getting the same errors over and over.” Sometimes, a measurement problem isn ...

(via PBS Space Time) The mystery of what happens when we go from a superposition to a definite state is known as the Measurement Problem, and it’s arguably the most mysterious outstanding problem in ...

What follows is a fairly complete transcript of a discussion about quantum physics on May 19, 1994, the last day of a workshop in Santa Fe, N.M. It begins with some technical issues, posed by John ...

The Journal of Educational Measurement (JEM) is a quarterly journal that publishes original measurement research, reports on new measurement instruments, reviews of measurement publications, and ...

Many research and productionapplications require low-level voltage measurements to characterize materialsand devices. When signal voltages approach the microvolt ...
