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.
GUM, the internationally approved technique for calculating measurement uncertainty, is reliant on the availability of a certified reference sample. Likewise, to find any repeatable offset (systematic ...
How does Thermo Fisher Scientific's analytical software support the calculation of measurement uncertainty? Wilhelm Sanders: According to DIN EN ISO 17025, it is necessary to calculate the measurement ...
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 ...

Optical clock sets new accuracy record, bringing us closer to a new definition of the second
A research team at VTT MIKES has set a new record in optical-clock absolute frequency measurements using a strontium ...
Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...
Researchers from the Polytechnic University of Madrid and Qualifying Photovoltaics, a Madrid-based PV engineering consultancy, have provided a series of practical recommendations for short-term ground ...
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 ...
