In Landau’s Fermi liquid picture, transport is governed by scattering between quasi-particles. The normal liquid 3He conforms to this picture but only at very low temperature. Here, we show that the deviation from the standard behavior is concomitant with the fermion-fermion scattering time falli...
We consider the problem of finding the energy spectrum of electrons localized above the surface of a liquid helium film under the electrostatic attraction of induced charges. We show that the forces of attraction to the charges induced on the surface of a conductor located beneath the film ...
To do this, the wires are continually bathed in liquid helium at 452.4 degrees below zero Fahrenheit (269.1 below zero degrees Celsius) [source: Coyne]. This cold is insulated by a vacuum. While superconductive magnets are expensive, the strong magnetic field allows for the highest-quality ...
You see glow-in-the-dark stuff in all kinds of places, but it is most common in toys. My son, for example, has a glow-in-the-dark yo-yo, a glow-in-the-dark ball, a glow-in-the-dark mobile and even (if you can believe it) a pair of glow-in-the-dark pajamas! They make...
Remember that these factors can sometimes be extreme in one of two ways: very hot or very cold, highly acidic or highly alkaline. Most organisms that we see or encounter subsist in temperatures ranging from 41 degrees Fahrenheit (5 degrees Celsius) to 104 degrees Fahrenheit (40 degrees Cel...
Among these, the three main scales are the Celsius scale, Fahrenheit scale, and the Kelvin scale. The Kelvin scale is considered to be the thermodynamic unit of temperature and is defined as 1/273.15 of the triple point of water's temperature....
The chamber is cooled down to almost absolute zero by a cryogenic source, such as a liquid helium refrigerator. A pump creates a very high vacuum in the chamber. The sample being scanned serves as one electrode. The probe tip, an incredibly small distance above, serves as the other electr...
Styrofoam is an insulator, which means it'll help keep the heat from the environment out of your cooler. However, you'll still need cooling agents (like ice packs) to make the cooler cold in the first place.
is deceptive; it takes cutting-edge aeronautical engineering, modern materials and precision manufacturing to pull one off -- which partly explains why an idea nearly as old as powered flight was repeatedly taken up and cast aside for decades before achieving limited success during the Cold War. ...
Homeostatic - Living things carry out functions that keep them in a constant, relatively unchanging state called homeostasis. For example, your body has systems that keep your body temperature constant -- you shiver if you're cold, sweat if you're hot. Reproduces - Living things make copies ...
