Devised by the German physicist Werner Heisenberg in 1927, the so-called uncertainty principle states that we cannot accurately know both the position and speed of a particle, such as a photon or ...

In 1927, Werner Heisenberg was in Denmark working at Niels Bohr's research institute in Copenhagen. The two scientists worked closely on theoretical investigations into quantum theory and the nature ...

Physicists in Australia and Britain have reshaped quantum uncertainty to sidestep the restriction imposed by the famous Heisenberg uncertainty principle—a result that could underpin future ...

State-of-the-art sensors, such as MRIs and atomic clocks, are capable of making measurements with exquisite precision. MRI is used to image tissues deep within the human body and tells us whether we ...

For almost a century, Heisenberg’s uncertainty principle has stood as one of the defining ideas of quantum physics: a particle’s position and momentum cannot be known at the same time with absolute ...

The uncertainty principle, first introduced by Werner Heisenberg in the late 1920's, is a fundamental concept of quantum mechanics. In the quantum world, particles like the electrons that power all ...

For centuries, scientific progress has depended on more precise tools for measuring the world around us. Galileo’s telescope revealed Jupiter’s moons and shook the geocentric universe. Thomas Young’s ...

Heard of Heisenberg’s uncertainty principle? It says the more certain we are of a quantum particle’s position, the less certain we are of its velocity, and vice versa. While that deals solely with the ...
