Smallest Atomic Displacements Ever and quantum foam

In summary, the conversation discussed a forum post and an article about the Heisenberg uncertainty principle. The article questioned whether at small distances, the principle was being encroached upon. However, it was clarified that the principle does not prevent exact knowledge of a particle's position, but rather its position and momentum at the same time.

hi, this is my first forum post, i hope it is in the correct category.
i was reading an article last month ...

http://www.sciencedaily.com/releases/2011/09/110901142058.htm

now at these small distances that can be measured is the hindenburg principle of uncertainty being encroached upon?
thanks

sorry about the quantum foam in the title as this become prominant at sub-Plank lengths.

Er... "hindenburg principle"?

Are you expecting something to crash and burn?

Zz.

yes i am expecting me to crash and burn on my first post!

i should stop copy/pasting..
i meant say Heisenberg uncertainty principle!

The Heisenberg uncertainty principle does not say that you can't know a particle position exactly. It says that you can't know the particle's position exactly AND its momentum exactly, at the same time. So there is no encroaching here.
 

FAQ: Smallest Atomic Displacements Ever and quantum foam

What are the smallest atomic displacements ever recorded?

The smallest atomic displacements ever recorded are on the scale of picometers (10^-12 meters), which is smaller than the diameter of an atom itself.

How are these small displacements measured?

These small displacements are measured using advanced techniques such as scanning tunneling microscopy (STM) and atomic force microscopy (AFM), which can detect changes in atomic positions.

What is the significance of these small displacements?

These small displacements play a crucial role in understanding the fundamental principles of quantum mechanics and can also help in developing new technologies such as quantum computing.

What is quantum foam?

Quantum foam is a theoretical concept that describes the fluctuations and fluctuations of space-time at a very small scale. It is thought to be made up of tiny, ever-changing bubbles of energy that constantly pop in and out of existence.

How are smallest atomic displacements related to quantum foam?

Smallest atomic displacements are a result of the fluctuations and fluctuations of quantum foam. The uncertainty principle of quantum mechanics states that it is impossible to know the exact position and momentum of a particle at the same time, and these small displacements are a manifestation of this principle.
