The researchers found that even with the molecular motors
driving the system
out of equilibrium, the defects were still able to sense the curvature, with the +1 / 2 defects migrating towards the region
of positive curvature and the -1 / 2 defects migrating towards the region
of negative curvature.
The team took the system, forced it
out -
of -
equilibrium using a
driving force, and subsequently switched the force off to measure the vibrational amplitude as the energy
of the system decayed.
In case
of a car jack, it could be enough for a big vehicle to
drive close to your car and blow it
out of the
equilibrium with the wind it creates.
[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in
equilibrium with water / ice, would precipitate
out if not for the CO2, so acts as a feedback; since the oceans cover so much
of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the
driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its
driving gradient decreases; the larger slower meanders increase the amplitude and duration
of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (
