while most other magnetoelectrics demonstrate an ME effect of this magnitude only at extremely low temperatures below -160 degrees Celsius. Bismuth ferrite is an antiferromagnetic, which means that the magnetic moments of its magnetic sublattices (structures formed by atoms with the same parallel spins...
Now we know what space is, it's easier to understand what a rocket is and how it works.A space rocket is a vehicle with a very powerful jet engine designed to carry people or equipment beyond Earth and out into space. If we define space as the region outside Earth's atmosphere, ...
Earth? It might be better called Oceanus: most of it is, after all, covered in water—much of it very warm water. The really interesting thing about the ocean is not how hot it is, but the difference in temperature between the surface (where the Sun keeps the sea relatively hot) and...
Environmental cues such as light, food, and temperature can modulate the rhythmicity of the CC10. It is also known that the CC is susceptible to external magnetic fields (MFs). In the 1960s, Brown et al.11found that small changes in the intensity of Earth’s MF synchronize the CCs of ...
How could the scientists have found the atomic number of the first element? What is the mass of a neutron? The quark composition of the proton is uud, while that of the neutron is udd. Show that the charge, baryon number, and strangeness of ...
"One of the nice things about our model is that it explains how a lunar dynamo could have lasted for a billion years," Nimmo said. "It also makes predictions about how the strength of the field should have changed over the years, and that's potentially testable with enough paleomagnetic ...

In physics, there are still manybig questions and mysteries. There are many phenomena which don't seem to fit, and we don't know how to explain yet. The "Fixion" is satirically presented as a particle which acts as aDeus ex machina, (see alsotvtropes), which solves all of these mys...
How can we store the power of the wind? Is wind the energy of the future? Which countries have most wind power? Micro-wind turbines Find out moreHow does a turbine generate electricity?A turbine, like the ones in a wind farm, is a machine that spins around in a moving fluid (liquid...
The degree of overlap between the plates alters the capacitance and that's what tunes the radio into a particular station. Some variable capacitors have a more "open" design that makes it easier to see how the plates work—and there's a great GIF illustrating that here. How do we measure...
