If you look closely at this old bank near Girona, you will see the remains of an ancient stone wall that nature has reclaimed, just as the jungle reclaimed entire Mayan cities. View in LinkedIn

MEGAMASER. When galaxies merge, they become extremely dense, and hydroxyl molecules produce a specific radio signal known as a maser in radio waves, and when that signal is very bright it is called a megamaser. A megamaser nicknamed Nkalakatha (a Zulu word that means big boss) has been detected 58 thousand billion billion kms from Earth, so the time that the light took to arrive could be greater than the age of the solar system. https://lnkd.in/ginnG4-u View in LinkedIn

CONDENSATE DROPLETS. “This brief review summarizes recent theoretical and experimental results which predict and establish the existence of quantum droplets (QDs), i.e., robust two- and three-dimensional (2D and 3D) self-trapped states in Bose-Einstein condensates (BECs), which are stabilized by effective self-repulsion induced by quantum fluctuations around the mean-field (MF) states.” https://lnkd.in/g78xpDpU View in LinkedIn

ULTRA-COLD MATTER. “Instead, the atoms fall into the same quantum states, and can't be distinguished from one another. At that point the atoms start obeying what are called Bose-Einstein statistics, which are usually applied to particles you can't tell apart, such as photons.” (Some planets are ultra-cold) https://lnkd.in/eu7-Pmkt View in LinkedIn

F ELECTRON ORBITALS. “The electron orbital letters go in the order s, p, d, f, g, h, i, j, etc. At the fourth and higher levels, there are seven f orbitals in addition to the 4s, 4p, and 4d orbitals. Counting the 4s, 4p, and 4d orbitals, this makes a total of 16 orbitals in the fourth level. They have even more complicated shapes. s, p, d, and f orbitals are available at all higher energy levels as well.” (Great graphics). https://lnkd.in/eaQ4p_NY View in LinkedIn

F ELECTRONS AND MULTIPOLARS. “These compounds have in common that the exotic multipolar electric or magnetic distribution occurs on the lanthanide or actinide ion and are thus generated by the f electrons.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

THE RARE MULTIPOLARS. “Thus far, true multipolar order has been discovered, or predicted, for about a dozen crystalline materials.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

HEN’S TEETH. “It turns out, however, that the appearance of true multipolar order, that is, of rank higher than dipolar order, is actually rare in solid state compounds.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

ORBITAL ASYMMETRY. “Since electrons on filled atomic shells lead only to spherical charge distributions, the electrons in open shells are responsible for the anisotropic charge and spin distributions and thus for the eventual appearance of multipolar order.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn
