But if we were shown a movie depicting
atoms jiggling around, until recently we could be reasonably sure we were looking at a cartoon, an artist's impression or a simulation of some sort.
Turin's more controversial theory, put forth in 1996 and now the subject of two popular books, holds instead that odorant receptors sense the way a molecule's
atoms jiggle.
(It is the reason helium ordinarily only occurs as a gas or a liquid: the extremely lightweight
atoms jiggle about too much to form a solid.)

«The
atoms are arranged in a regular periodic grid and are not
jiggling around, as in a liquid,» says Coh.
Normally, you only see quantum - mechanical
jiggling when you look at objects the size of
atoms and molecules, but we are moving into a domain where we see the centers of mass of these big mirrors
jiggle quantum - mechanically.
(Einstein's 1905 model of the erratic
jiggling of microscopic particles was used to prove the existence of
atoms.)
For the first time, new research from the University of Bristol, UK and the University of Waikoto, New Zealand explains how this «wiggling and
jiggling» of the
atoms in enzymes — the proteins that make biological reactions happen — is «choreographed» to make them work at a particular temperature.
Instead, the deformation produced a decrease in the oscillation frequency at higher temperatures — so high that the
jiggling of
atoms would be expected to destroy any quantum effect such as supersolidity.
At high temperatures, the
jiggling atoms point in random directions and their magnetic fields cancel one another.
A characteristic of helium would tend to promote such an exchange — namely, its large zero - point motion, which is the inherent
jiggling of
atoms that represents a minimum amount of movement required by quantum uncertainty.
Typically, MRI detects the
jiggling of hydrogen
atoms perturbed by strong magnets.
In contrast, a tiny machine unveiled this year
jiggles in ways explicable only by the weird rules of quantum mechanics, which ordinarily govern molecules,
atoms, and subatomic particles.
The challenge is being able to detect such minute variations while screening out far larger sources of background noise, such as vibrations caused by earthquakes or the thermal
jiggling of
atoms.
The
atom feels that
jiggle and can transfer the
jiggle into a light signal we can pick up.
