Quantum carpets, carpets of light
In 1836 Henry Fox Talbot, an inventor of photography, published the results of some experiments in optics that he had previously demonstrated at a British Association meeting in Bristol. "It was very curious to observe that though the grating was greatly out of the focus of the lens...the appearance of the bands was perfectly distinct and well defined...the experiments are communicated in the h...
متن کاملNumerical Carpets
1 June 1, 1998 Introduction It has long been known that modular arithmetic often produces interesting numerical patterns. These patterns can be made easier to comprehend and more interesting by rendering them as images with colors associated with numerical values. The example most often cited is Pascal’s Triangle, which exhibits the binomial coefficients. If you take the coefficients modulo m f...
متن کاملHazardous Chemicals in Carpets
This study was undertaken to investigate whether certain hazardous chemicals were present as components in new carpets, and if so, in what quantities. The study included analysis of eight new carpet samples that were available for retail in the UK. Some of the carpet samples contained high levels of organotins, in particular TBT (up to 47,500 ppb).

Most of the research on stress conducted to date has focused on physical and psychological aspects; however, there are very few reports about the association between psychological stress and elements within the residen...
متن کاملPatterned polymer carpets.
For the development of polymer carpets as active devices for micro- and nanotechnology, a control of the polymer carpet morphology and especially control of the stimulus responsive polymer brush is needed. Here, we report on the first example for the fabrication of patterned polymer carpets. On a two-dimensional framework of fully crosslinked and chemically patterned nanosheets, polymer brushes...
