One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being ...

Uncertainty affects the accuracy with which measurements can be made in quantum physics. To reduce this uncertainty, physicists have learned to "squeeze" certain measurements. Researchers are now ...

where N is the number of selected events, N BG is the number of background events, f ξ < 5 × 10-6 is the fraction of events that pass the event selection but have ξ<5×10 −6, is the integrated ...

Despite its many successes, physicists are still struggling to nail down a coherent interpretation of quantum mechanics, as it best represents “reality”. Jim Baggott explores the arguments first put ...

CBSE Class 11 Physics notes on Chapter 2, Units and Measurement (Part 3) are available here. Important topics covered in this part are Accuracy, Precision, Errors of ...

Daniel Shaddock is co-founder of Liquid Instruments and professor of physics at the Australian National University in Canberra. He spoke with Hamish Johnston about innovation in the test and ...
