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 ...

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 ...

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 ...

Scientific progress has been inseparable from better measurements. Before 1927, only human ingenuity seemed to limit how precisely we could measure things. Then Werner Heisenberg discovered that ...

Contrary to what many students are taught, quantum uncertainty may not always be in the eye of the beholder. A new experiment shows that measuring a quantum system does not necessarily introduce ...

In the test and measurement industry, two distinct camps exist: those who favor vector network analyzers (VNA) and those who favor time domain reflectometers (TDR). Each camp relies heavily upon its ...

One of the most important—and famous—results in quantum mechanics is the Heisenberg Uncertainty Principle (HUP). What is less known (at least to non-physicists) is that the HUP exists in two versions.

More than 80 years after the uncertainty principle was first proposed, scientists are ironing out some uncertainties about the famous physics notion. The uncertainty principle, proposed in 1927 by ...

Physicists in Austria and Japan are the first to measure two physical quantities that were used in 1927 by Werner Heisenberg in an early formulation of quantum mechanics – but then abandoned because ...

The principal tool in the Atmospheric Physics Lab is a Fourier Transform Infrared (FTIR) spectrometer. Because the OH stretch (which is an IR active transition) in the water molecule is particularly ...
