Scientists studying a mysterious effect called cosmic birefringence—a subtle twist in the polarization of the universe’s oldest light—have developed a new way to reduce uncertainty in how it’s ...

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 ...

One of the most often quoted, yet least understood, tenets of physics is the uncertainty principle. Formulated by German physicist Werner Heisenberg in 1927, the rule states that the more precisely ...

What is the meaning of Heisenberg’s analogy? (Courtesy: German Federal Archives) A row has broken out among physicists over an analogy used by Werner Heisenberg in 1927 to make sense of his famous ...

The NA62 Collaboration has dramatically reduced the uncertainty in its measurement of an extremely rare particle decay, in ...

Today, we can measure the position of an object with unprecedented accuracy, but the uncertainty principle places fundamental limits on our ability to measure. Noise that results from of the quantum ...

In the microscopic world of the quantum particle, there are certain rules that are wholly unfamiliar to us on a macroscopic scale. If you measure a particle's position and ask "where are you," the ...
