Sentences with phrase «on macroscopic scales»

It describes particles, atoms and molecules but gives way to ordinary classical physics on the macroscopic scales of pears, people and planets.

Gravity, however, operates predominantly on macroscopic scales.

The individual forces are the weakest binding forces that exist in nature, but they add up to reach magnitudes that we can perceive very clearly on the macroscopic scale — as in the example of the gecko.

«On a macroscopic scale this is equivalent to observing the world through a set of louvers... that allow light to enter from one direction only,» Pendry says.

If we, say, found that on a macroscopic scale it somehow becomes proportional to the second power of Nv that would be a little alarming.

Not exact matches

Water's behavior was tested with three different approaches: ultrafast optical measurements, which revealed the arrangement of molecules on the nanometric scale; a computer simulation on the atomic scale; and measurement of the water's surface structure and tension, which was done at the macroscopic level.

Ye is most excited about the future possibility of using the atoms in the clock as a gravity sensor, to see how quantum mechanics, which operates on very small spatial scales, interacts with general relativity, the theory of gravity, a macroscopic force.

McKay suggested that the Viking Mars lander may have inadvertently oxidized any evidence of life it its samples of Martian soil, proposed an expedition to gather samples of water from the Saturn moon Enceladus, and offered a child - friendly analogy for how alien life might differ from life on Earth: «I could build a table out of Lincoln logs and you could build a table out of Legos: At the macroscopic scale they'd be the same — they'd both be tables; at the microscopic scale they'd be the same — they'd both be built from carbon atoms.

Thermodynamics is a branch of physics that studies the effects of changes in temperature, pressure, and volume on physical systems at the macroscopic scale by analyzing the collective motion of their particles using statistics.

In a system such as the climate, we can never include enough variables to describe the actual system on all relevant length scales (e.g. the butterfly effect — MICROSCOPIC perturbations grow exponentially in time to drive the system to completely different states over macroscopic time) so the best that we can often do is model it as a complex nonlinear set of ordinary differential equations with stochastic noise terms — a generalized Langevin equation or generalized Master equation, as it were — and average behaviors over what one hopes is a spanning set of butterfly - wing perturbations to assess whether or not the resulting system trajectories fill the available phase space uniformly or perhaps are restricted or constrained in some way.

They neglect the fact that thermodynamics is the valid macroscopic heuristic for statistical mechanics, and that stat mech computations can not be done on an heuristic basis at all; they are horrendously difficult, involving taking limits of nearly infinite sums in just the right way to get the relevant part of the answer and discard the parts that don't scale up to relevance as one goes to large systems.
