Is There a Crystal Lattice Possessing Five-Fold Symmetry?
Kepler’s Mosaics TheGermanscholar Johannes Kepler (1571–1630), who worked as a court mathematician for the Holy Roman Emperor Rudolf II in Prague, is well known especially for his astronomical discoveries.We still today admire his ability to obtain his three laws of planetary motion from data analysis of Tycho Brahe’s observations of Mars. Another outstanding discovery is Kepler’s equation desc...
متن کاملFive-fold symmetry in crystalline quasicrystal lattices.
To demonstrate that crystallographic methods can be applied to index and interpret diffraction patterns from well-ordered quasicrystals that display non-crystallographic 5-fold symmetry, we have characterized the properties of a series of periodic two-dimensional lattices built from pentagons, called Fibonacci pentilings, which resemble aperiodic Penrose tilings. The computed diffraction patter...
متن کاملPossessing Local Relativistic Symmetry
It is shown that the problem of a possible violation of the Lorentz transformations at Lorentz factors γ > 5×10 10 , indicated by the situation which has developed in the physics of ultra-high energy cosmic rays (the absence of the GZK cutoff), has a nontrivial solution. Its essence consists in the discovery of the so-called generalized Lorentz transformations which seem to correctly link the i...
متن کاملSize-Selected Ag Nanoparticles with Five-Fold Symmetry
Silver nanoparticles were synthesized using the inert gas aggregation technique. We found the optimal experimental conditions to synthesize nanoparticles at different sizes: 1.3 ± 0.2, 1.7 ± 0.3, 2.5 ± 0.4, 3.7 ± 0.4, 4.5 ± 0.9, and 5.5 ± 0.3 nm. We were able to investigate the dependence of the size of the nanoparticles on the synthesis parameters. Our data suggest that the aggregation of clus...
متن کاملWhy Believe That There Is a God?
This article presents an argument for the existence of God, showing that the evident phenomena are best explained by supposing that a God causes them. The argument is based on the inductive force of four very evident general phenomena: that there is a physical Universe; that it is governed by very simple natural laws; that those laws are such as to lead to the existence of human bodies; and tha...
