Quantum fluctuations mean that the vacuum is not empty as it is assumed in classical physics. These fluctuations, also known as zero-point fluctuations, produce measurable effects in superconducting electronic devices (Josephson junctions). The energy of zero-point fluc...

Computer reconstructions of heritage sites provide us with a means of visualising past environments, allowing us a glimpse of the past that might otherwise be difficult to appreciate. However, it is essential that these reconstructions incorporate all the physical evide...
