An understanding of molecular dipoles provides insight into how molecules interact and helps to explain many of their properties. A molecule possesses a dipole if it is electrically asymmetric, i.e. if the centers of the distributions of positive and...

In physics, there are two kinds of dipoles (Hellènic: di(s)- = twi- and pòla = pivot, hinge). An electric dipole is a separation of positive and negative charge. The simplest example of this is a pair of electric charges of equal magnitude but...

How empirical analyses provide but a limited perspective A physicist was asked to advise a dairy farmer on ways to improve the productivity of cows. At their first meeting the physicist drew a large circle on his notepad and said to the farmer,...

ABSTRACT A new class of exact vortex dipole solutions is derived for surface quasigeostrophic (sQG) models. The solutions extend the two-dimensional barotropic modon to fully three-dimensional, continuously stratified flow and are a simple model of localized jets on the tropopause. In addition to...

Historians investigating the life of a Dutch Nobel chemistry laureate who worked in Germany during Adolf Hitler's Nazi regime found the scientist complied with anti-Jewish dictates while sometimes helping Jewish colleagues.Peter Debye, who won the Nobel in 1936, was posthumously stripped of honors by two...
