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 ...

Quantum particles are not really just particles…they are also waves. The word uncertainty is used a lot in quantum mechanics. One school of thought is that this means there's something out there in ...

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 ...

The Heisenberg Uncertainty Principle, formulated by physicist Werner Heisenberg in 1927, reminds us that there are fundamental limits to what can be known simultaneously about certain pairs of ...

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 ...

In quantum mechanics, it is impossible to know both exactly where you are and exactly where you are going. This idea, known as Heisenberg’s uncertainty principle, has been a key part of studying the ...

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 ...

Dr Christophe Valahu in the Quantum Control Laboratory at the University of Sydney Nano Institute. Dr Valahu is standing in front of the ion trap used in the experiment. Physicists in Australia and ...

Scientists generated ultrafast light pulses with controllable, real-time quantum uncertainty, visualizing Heisenberg’s ...
