He also adds that the theory “seems to agree quantitatively with experiment only for T ≲ 100 mK”. This is very low compared to ~ 5 K, the degeneracy temperature of non-interacting fermions calculated with the bare mass of the 3He atoms. The properties of the ground state (...
In order to keep up with a changing environment, mobile organisms must be capable of deciding both where and when to move. This precision necessitates a strong sense of time, as otherwise we would fail in many of our movement goals. Yet, despite this intrinsic link, only recently have rese...

This show used to be really good and quite informative but the last few seasons have gotten dumber & dumber. If you're interested in this subject enough to watch the series, you're going to have some basic knowledge of the universe but this series seems to assume that only five year old...
Analyses of the kinetic energy-dependent TCID cross-sections yield 0 K experimental BDEs for these compounds. To complement the experimental BDEs, we compare our measured values to theoretical values calculated at three levels of theory and to existing literature values [8,9,10,11]. In addition,...
A paranoid point, a point of blockage, an outburst of delirium: it comes across clearly in Speed, by William Burroughs, Jr. Is it possible to locate this danger point, should the block be expelled, or should one instead "love, honor, and serve degeneracy wherever it surfaces"? To block...

Aromaticity is one of the most important concepts in chemistry, and it is associated with cyclic electron delocalization (or conjugation) in closed circuits giving rise to bond-length equalization, energy stabilization, large magnetic anisotropies and abnormal chemical shifts, among other well-known eff...
Since its formulation, the heat death concept caused paradoxically an increasingly lively scientific effort to reconcile it with the empirically observed reality. It has been noted long ago that gravity has the capability of circumventing the heat death “theorem” because the gravity energy is not ...
The large inter-base distance (3.5–4.0 Å) provides the spatial allowance to boost the methyl distortion, thus removing the excess excitation energy. The thymine oligomer ultimately evolves in the energetic degeneracy region between SCT(1ππ*) and ground states, i.e., CI(1ππ*/S0), ...
