has been the uncertainity principle proved wrong ?
The Heisenberg Uncertainty Principle is one of the most well-known and dearly held tenets of modern quantum physics. Its one of those things about science you totally know, even if you dont know you know it. The principle states that on a quantum level, you cant directly measure anything without changing something about it.
Thanks to new measurement techniques, physicists are no longer uncertain that the theory holds up.
Researchers at the University of Toronto may have overcome this obstacle to finely measure quantum particles with a new technique known as weak measurement. In using a weak measurement, the device on which the particle is being measured is nearly imperceptible. After a first weak measurement, researchers sent the particle into a device that measured its velocity, and then measured its mass again using the weak measurement, giving them a good look at how much the act of measuring actually disturbed the particle.
