Iz zbornika Kmice: Ocena polmera Zemlje na plaži, Milan Ambrožič. Ležiš na plaži in Sonce ravno zaide. Vstaneš (višina človeka h) in še enkrat počakaš, da Sonce izgine. To traja okoli t = 10 s. V tem času se Zemlja zavrti za kot \varphi = 2\,\pi\,t\over t_0, t_0 = 24 ur. Iz geometrije ugotovimo {R\over R+h} = \cos\varphi. Razvijemo kosinus in izračunamo polmer Zemlje R. Referenca: Halliday, Resnik, Walker, Fundamentals of Physics, 1997. Pomanjkljivosti: ne upoštevamo nagnjenosti zemljine osi, loma svetlobe zaradi različnih temperatur ozračja. Nagnjenost se na zemljepisni širini 45 stopinj pozna tako, da je cas t v resnici 17 s namesto 10 s.

New research led by an electrical engineer is aimed at improving lithium-ion batteries through possible new electrode architectures with precise nano-scale designs. The researchers created nanowires that block diffusion of lithium across their silicon surface and promote layer-by-layer axial lithiation of the nanowire's germanium core.

Sept 2013:

Using low-frequency laser pulses, a team of researchers has carried out the first measurements that reveal the detailed characteristics of a unique kind of magnetism found in a mineral called herbertsmithite. In this material, the magnetic elements constantly fluctuate, leading to an exotic state of fluid magnetism called a "quantum spin liquid." This is in contrast to conventional magnetism, found in materials called ferromagnets -- where all of the magnetic forces align in the same direction, reinforcing each other -- or antiferromagnets, where adjacent magnetic elements align in opposite directions, leading to complete cancellation of the material's overall magnetic field

All living things must obey the laws of physics -- including the second law of thermodynamics, which states that the universe's disorder, or entropy, can only grow. Highly ordered cells and organisms appear to contradict this principle, but they actually do conform because they generate heat that increases the universe's overall entropy.http://www.sciencedaily.com/releases/2013/08/130827113031.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fmatter_energy%2Fphysics+%28ScienceDaily%3A+Matter+%26+Energy+News+--+Physics%29

The new material may have very good properties for application as electrodes in for example Li-ion batteries.
