The Effects of Video Games on Human Intelligence
With the help of rapidly growing electronics industry offering more affordable electronic gaming devices, an increasing number of people have stepped into the realm of video games and as a result, playing video games has become part of life for many to some extent. While the majority of people are embracing the fun and the thrill that video games have brought about, a handful of people are still holding relatively negative opinions on video games, thinking that playing video game is just a waste of time and money. In fact, the truth is quite the opposite. It has proved that video game is actually playing a multifaceted positive role in improving people’s intelligence, or making people smarter on the physiological aspect, the psychological aspect as well as the sociological aspect
Soft vibrational mode associated with incommensurate orbital order in multiferroic CaMnO
We report inelastic light scattering measurements of lattice dynamics related
to the incommensurate orbital order in . Below the
ordering temperature , we observe extra
phonon peaks as a result of Brillouin-zone folding, as well as a soft
vibrational mode with a power-law -dependent energy, . This temperature dependence demonstrates the
second-order nature of the transition at , and it indicates that
the soft mode can be regarded as the amplitude excitation of the composite
order parameter. Our result strongly suggests that the lattice degrees of
freedom are actively involved in the orbital-ordering mechanism.Comment: 7 pages, 8 figure
