Sentences with phrase «at macroscopic scales»

Statistical mechanics was developed to study solids, gasses and liquids at macroscopic scales, but is now used to describe a variety of complex states of matter, from magnetism to superconductivity.

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 the familiar heat engine model at macroscopic scale, referred to as the Carnot heat engine, the efficiency increases as a function of the ratio between the temperatures of the low - and high - temperature baths.

At the macroscopic scale, we are familiar with the idea that sensors and actuators have to deal with the physical world, but the information - processing unit is isolated from the physical world.

The HCP seeks to map brain connectivity at a macroscopic scale, using magnetic resonance imaging (MRI).

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.

Designing materials for use in the large variety of gadgets and structures that support our everyday lives involves understanding them at their atomic, electronic and macroscopic scales.

X-ray imaging will allow them to visibly see materials and features at the macroscopic level as they evolve during deformations, while simultaneous X-ray diffraction measurements will permit them to examine the deformations at the microscopic scale.

Around the mid-1980s, however, scientists discovered that gold's chemical aloofness only manifests at large, or macroscopic, scales.

The system thus takes advantage of physical measurements at the microscopic scale, while enabling computationally efficient evaluation of macroscopic designs.

Under such supercooled conditions, a large fraction of the atoms collapse into the lowest quantum state, at which point quantum effects become apparent on a macroscopic scale.

The core facility is a two - photon in vivo imaging platform developed at the Nonlinear bioimaging laboratory, a technique that allows for non-invasive structural and functional measurements in small animal models at different scales: from macroscopic imaging of the brain morphology to highly resolved microscopy of neuron populations, single neurons, and even subcellular structures.

Quantum mechanical weirdness that operates at atomic scale does not invalidate this physical description of the macroscopic range that is of interest.

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.

(Of course, the distinction between «ice» and «water» begins to lose meaning at such a small length scale since phases of matter are themselves a macroscopic concept.)
